Architecture Misfit #25: Ernst May

Ernst May
[July 1886 — September 1970]

New Frankfurt [in German, Neues Frankfurt] was an affordable public housing program in Frankfurt started in 1925 and completed in 1930. The mayor of Frankfurt hired Ernst May as general manager of the project to bring together architects to work on it. The goal was housing that could be rented for no more than 25% of a person’s monthly income.

May’s developments were remarkable for their time for being compact. The 60 sq.m. area of a typical three-room apartment was fifteen sq.m. less than the standard for the time. Economic pressures led to two-room apartments for four people having an area of 40  sq.m. These were known as transitional minimum subsistence dwellings. The plan was to later combine them into larger units.

The housing units were semi-independent, well-equipped with community elements like playgrounds, schools, theatres, and common washing areas. This is admirable.

May used simplified, prefabricated forms for the sake of economy and construction speed. This shows a comprehension of the scale and urgency of the problem.

The settlements were planned to have new ideals such as equal access to sunlight, air, and common areas. This was most progressive.

The settlement layouts and the dwellings and their spaces were highly functional. This was not the pursuit of functionalism as a style, but a means of not wasting space and the building materials to enclose it.

The development of the Frankfurt Kitchen in 1926 by Austrian architect Margarete (Grete) Schütte-Lihotzky was one of the offshoots of their joint research. It was the first unit kitchen.

May was responsible for the production of approximately 15,000 housing units between 1925 and 1932. This is a huge achievement for any person in any country in any era, but was in Germany during a period of INCREASING POLITICAL TURMOIL – a period that, as it happened, coincided with the heyday of the Bauhaus.

Here’s what happened.

Johnson & Hitchcock have nothing to say about May, save for this parenthesised reference on p233 of The International Style.

Others however noticed. May’s achievements were recognised at the 1929 CIAM conference. This brought him to the attention of the Soviet Union.

In 1930 May took virtually his entire New Frankfurt-team to Russia. … The promise of the “Socialist paradise” was still fresh, and May’s Brigade and other groups of western planners had the hope of constructing entire cities. The first was to be Magnitogorsk. Although May’s group is indeed credited with building 20 cities in three years, the reality was that May found Magnitogorsk already under construction and the town site dominated by the mine. Officials were indecisive, then distrustful, corruption and delay frustrated their efforts, and May himself made misjudgements about the climate. May’s contract expired in 1933, and he left for Kenya (then British East Africa).

May’s reputation thus went the same way as Architecture Misfit #1: Hannes Meyer and Architecture Misfit #23: André LurçatMay isn’t mentioned much in the history of modern architecture. It’s not just because he went to the Soviet Union when other German architects were busy brushing up their English. May was a professional who, when given the problem of providing housing for the country’s population, didn’t see his role as developing prototypes for mass production, but to actually make it happen. And he did. 15,000 of them. And they’re still lived in.

Despite existing from 1919–1932, the Bauhaus contributed little to solving Germany’s housing problem. Gropius’ Dessau-Törten Estate of 1926–1928 provided 317 dwellings with areas of 57–75 sqm but it was a job on the side, independent of his 1919–1928 stint as Bauhaus director. Gropius put the experience to good use and, immediately upon leaving the Bauhaus in 1928, won a competition for the design of Dammerstock Colony. In 1934 he was to leave Germany and its mass housing problems behind him forever.

Dammerstock_vista_aerea_desde_oeste.jpg

For the period 1926–1928 at the very least, Gropius was involved with both architectural education and the solving of real-world housing problems but, for a person renowned as an educator, the thought that education might be about training people to solve real-world problems never seems to have crossed his mind. He kept education and real-world problems very separate. It didn’t do his career any harm but, if we were to ask when the rot set in, it would be here. I use the term architectural education loosely, as Gropius must have on his CV, for it was Hannes Meyer who added architecture to the Bauhaus curriculum. And it was Meyer who connected architecture with the solving of real-world problems, only for Mies to separate it again. What happened afterwards – and, unfortunately for us –  is not history.

It’s often said Hitler’s preference for pitched roofs was responsible for the dissolution of the Bauhaus. Perhaps it was, but Ernst May still managed to get 15,000 flat-roofed housey things built before leaving Germany in 1930, four years before Gropius and eight years before Mies. May’s leaving was the greater loss for Germany. In 1954 he was invited back and began work again at the planning department of the City of Hamburg.

Corner Stores

Corner stores are the opportunistic colonisers of underused space for our benefit. They’re the friendly bacteria of cities. Cities don’t work because of enigmatic signifiers, junk space or parameters. They work because of corner stores.

There’s not much about corner stores we don’t already know, apart from possibly the fact they’re usually called that because they’re located on the corner plots or street ends of rows of terraced housing, often Victorian or Edwardian factory workers’ houses. Here’s one from the early 1900s. It doesn’t look like the UK.

CornerStoreEarly1900s-long goodbye

Even if they didn’t stock Salada Tea, corner stores were a common sight in Britain until the 1970s. Many closed with the advent of large supermarkets that combined the services of many small local stores into a single building with lower overheads, centralised purchasing and whatnot. But many survived by offering a wider variety of services or opening for longer hours. Immigrant families had a competitive advantage as they were more likely to work those longer hours. Many stores were absorbed into franchises such as SevenEleven and came to be known as convenience stores.

store

Trivia. In the states of Western Australia and South Australia, a small convenience store is often known as a deli (a contraction of delicatessen). Elsewhere, deli retains more of its original meaning.

the-corner-deli

But wherever you are, corner stores are there for you when you run out of milk or bread. They’re there for you when you discover you’ve no tea or coffee for the morning, or when there’s people coming over and you forgot to buy cigarettes, alcohol, crisps and nuts. Many London convenience stores have a wide selection of cigarettes, alcohol, crisps and nuts as if that’s all city dwellers exist on.

This only reinforces the myth that the countryside is where real food exists, as told in Elizabeth David’s lovely book French Country Cooking. That myth was responsible for people wanting Agas and country-kitchens like the one below.

OLYMPUS DIGITAL CAMERA

This is exactly the kind of kitchen Alain de Botton describes in his book, The Architecture of Happiness. I had to throw the book away when I came across the line  “what could be more pleasant than the early-morning sunlight striking the honey-coloured stone of your kitchen floor?” (I paraphrase, but if you want to find it, you won’t have to read too far.) All this sentence tells me is that

  • your kitchen is a separate room with a window so you probably don’t live in a studio apartment – you live in a house
  • the early-morning (i.e. low-angle) sunlight enters your kitchen and strikes the floor so you probably have a rather large garden outside your kitchen window (i.e. you are rich)
  • you definitely don’t live in an apartment – at least not in London – because your kitchen has a stone floor
  • you are rich (or at least aspirational) because that stone is “honey-coloured” and it’s probably Yorkstone
  • Alain deBotton is a tosser

Of course, we all know that real food doesn’t exist in the countryside. It exists in urban restaurants because now we all want restaurant kitchens – or at least stainless steel stuff raised off the floor. The kitchen in this next image also works the common belief that good food comes not only from restaurants but from Italy.

hottest-stainless-steel-kitchen

It’s a winning combination of associations this next kitchen doesn’t have.

Contemporary-House-with-Completely-Stainless-Steel-Kitchen-with-kitchen-island-sink-oven-stove-cabinet-table-refrigerator-hood

I digressed – but not by much. While all that was happening, the larger UK supermarkets built large out-of-town stores disguised as generic country-style buildings and trained people to do a “weekly shop” from a store on an arterial road in the bountiful countryside.

Sainsbury's_Bradford_on_Avon

An increasingly large proportion of the population without cars but with a certain amount of disposable income remained unexploited and this, like smoke follows fire, led to “urban supermarkets” a.k.a. chain spinoff stores selling cigarettes, alcohol, nuts and crisps. You won’t find steak, onions, spinach or salmon in many, if any. I have a memory of going to this one on Fulham Road, London but to buy what, I don’t know. Cigarettes probably, truth be told.

Stores like these are a new revenue earner for large supermarket chains. Chains without them have profit warnings. Stores like these are spreading from city to suburb, forcing existing corner stores to be even more adaptable and diversify their services to include public transport cards, lottery tickets, post-office services, prepaid cards or recharges for mobile or transport, etc. The battlefield is convenience.

corner-shop

  • Because of their family ownership and management, corner stores open for longer and with fewer holidays. This is good for you.
  • Home deliveries are more personal, more immediate
  • You can get many things done at a decent corner store.
  • If you get on good terms with the management, they may even let you run up a bill you can settle monthly

To sum up, corner stores are good. They’re here in Dubai too, and – ma shah’allah – they’re on corners! The standard 40m x 40m tower has four corners. Meet Millennium Tower (2006, ATKINS. Burj Al Arab reprise as pseudo-truss – believe me, I know.)

P1010700

Whatever we may think of Millennium Tower, the FoodLand store on the ground floor MAKES IT BETTER! Note the tricycles for stable and free home delivery.

P1010706

In buildings such as Millennium Tower, the double ground floor height means it’s possible to get a mezzanine in there for added stock. Win-win for all.

You can see this is a functioning supermarket by what’s on the shelves. It provides local residents with not only the stuff they need, but the stuff they might need. Just up the road is Oasis Tower, the one behind the 19th Street sign.

P1010728

P1010743

Oasis House is host to not one but two corner stores.

P1010732

P1010736

Do a 180 and you’ll be looking at Liberty House.

P1010731

Back in the pre-CC day, its four-storey lobby was all just space and sofas and babbling water in rock-lined pools delineating rows of columns as skirting boards might. Not now.

These days, the lower 4.50 metres of that space is colonised by an ALMAYA supermarket. Technically, Almaya isn’t a corner store not because it’s not on a corner but because it’s part of a small chain.

P1010745

I include it anyway because it well shows what happens when need meets under-exploited space. Plus – because Liberty House and I have history.

This post has no point other than to say LET’S HEAR IT FOR CORNER STORES! YAY!! They’re not architecture, they’re not even buildings FU. P.S.). They’re just some space with some useful stuff in them. Living is more than architecture, more than just shelter.

Architecture Misfit #12: Nader Khalili

NADER KHALILI

Nader Khalili (1936–2008)

Nader Khalili is a good example of an architecture misfit. He really only had one idea. Put whatever sandy stuff is available, into bags, clad it and bingo you have a structure. In 1984 NASA was suitably impressed.

In 1984, Lunar and Space habitation became an integral part of his work. He presented his “Magma Structures” design, based on Geltaftan System, and “Velcro-Adobe” system (later to become Superadobe) at the 1984 NASA symposium, “Lunar Bases and Space Activities of the 21st Century.” He was subsequently invited to Los Alamos National Laboratory as a visiting scientist. 

Later however, he devoted his energies to the problem of how to build shelters for people in the world who have no money and the earthbag building is what he came up with. You’ve probably read about them sometime in the past several years. It difficult to think of a better solution to emergency or ultra-low cost housing.

The principle is simple. 1) Put sand into long bags and use them to make curved walls that act as their own stabilisers.

709033552_cal-earth-nader-khalili-1ED1

2) Make spaces for openings as you wish.

naderkhalili_ecodome_esquisse

3) The earthbag curves are laid in gradually decreasing radii to form domes.

4) The entire thing is finished according to your local stucco and culturo-personal preference.

The construction method is infinitely variable, durable, earthquake resistant, thermally impressive and, above all, dirt cheap. It requires little skilled knowledge or labour to build. The most expensive component is the bags and the barbed wire [ ! ] that is ingeniously used to increase friction between the bags.

earthbag-basement-sm

What’s not to like? In the world of glossy architecture, possibly all of the above despite the fact that the system can also be used to construct some conventionally appealing spaces and in some conventionally appealing shapes

EarthBag Home -10

and that have some fairly complex spatial arrangements.

casavergara18

No disrespect intended to Calearth,

cal-earth-header-designs

but the Californification of Khalili’s system for off-grid living should not be allowed to overshadow its fundamental humanitarian purpose of providing low-cost and/or emergency housing.

So then, Nader Khalili

You created a system that enables anyone
with some earthbags and land, to build a dwelling
that is sturdy, durable and comfortable.
For services to architecture and humanity

POSTSCRIPT: Acoustic suppression is not normally considered a major indicator of building performance but, apparently, Khalili’s structures reduce external noise by 17dB. Today’s Guardian reported that Heathrow airport is to pay 21 local schools to build Khalili’s “superadobe” shelters.

Pupils of Hounslow Heath school play around the huts in the playground as another low jet flies in

How this works out to £85,000 per school suggests someone is paying through the nose. Never trust those London builders’ quotes!

Architecture Misfit #10: Colin Lucas

colin anderson lucas

Colin Anderson Lucas (1906–84)

was an English architect and pioneer of reinforced-concrete construction. He formed a company to build concrete structures in the style of International Modernism, including Noah’s House at Spade Oak Reach, Bourne End, Bucks. (1930), and Hop Field House, St Mary’s Platt, Wrotham, Kent (1933—with Amyas Connell and Basil Ward (1902–76).

house in kent In 1933 he joined Connell and Ward to form Connell, Ward, & Lucas, and brought his expertise to the creation of a whole series of International Modernist houses such as High and Over Estate, Amersham, Buckinghamshire. (1929),

high_and_over_mvs210610_1

There’s more information and pics here. And here’s a short contemporary (1931) film about it, titled The House of a Dream.

There was also the Gunn House, The Ridgeway, Westbury-on-Trym, Bristol (1936),

Gunn House the Tarburn House, Temple Gardens, Moor Park, Herts. (1937–8), Walford House, 66 Frognal, Hampstead, London (1937)

frognal and Potcraft, Thomas House, Sutton, Surrey (1938) unparalleled elsewhere in the country. In short, until WWII he had quite a respectable career.

After the 1939–45 war he worked in the Architects’ Department of the London County Council, heading a team of young Modernists who designed, among much else, the Le Corbusier-inspired Alton Estate West at Roehampton, London (1951–78), where the slab-blocks are on a very small scale yet superficially modelled on Le Corbusier’s Unités d’Habitation.

History tells us nothing of why Lucas went to work in the Architects’ Department of the London County Council which, in the 1950s, was the largest architectural practice in the world. But he did.

It was a move away from one way of making buildings, and towards to another way of making  buildings. It was the change from making little architectural one-offs for the benefit of wealthy individuals and one’s own reputation, to using one’s skill as an architect to improve mass housing prototypes for the good of many, largely anonymously. 

There’s more to see and hear here about the London County Council but this next image shows part of the Alton West Estate.

alton estate westI’m not so sure the Alton West slab blocks are ‘superficially modelled’ on Le Corbusier’s Unités d’Habitation for in some ways they’re better. Here’s a plan of Ud’H 1.0 – Marseilles.

Unite Typical Floor Plan

  • Instead of a central corridor every third floor, Alton West has gallery access every second. These corridors will be cold, but bright. Horses for courses.

alton west corridor

  • The apartments at Alton West are double storey but have no double storey living room (like Apartment A at Ud’H) or no double storey master bedroom (like Apartment B at Ud’H) for that matter. At last, somebody’s redrawn the section!

CORBGRAPHIC

  • The kitchens at Alton West are separate and have windows (and larders!). This was a buildings regulations requirement. There is a hallway – building regs again – and bedrooms of usual (regulated) minimum width. All quite nice really.

alton-west-slab-fp-01

As well as adpating PJ’s prototype for British building regulations, the London County Council architects were trying to improve upon what PJ had proposed. The interlocking plan, central corridor and double-height living rooms were never an option. The double height living/bed room is a waste of enclosed volume that could be more responsibly provided with a floor and used to house more people. It is also a poor use of surface area if regulations require your kitchens and bathrooms to have windows.  

But all of this is to miss the most important difference. At Alton West there are five slab buildings, not one. There are almost twenty point blocks.

alton west

Let’s have a closer look at those point blocks.

point blocks at alton west

This is the sunny side.

3585226403_6a8317074d_z

These buildings are stair-rich, presumably because of stricter fire code back then.

alton-west-point-fp-01

  • All apartments are corner apartments, as you’d expect with four apartments and point access.
  • No two living rooms are horizontally adjacent.
  • Less space is used for circulation, even with the two stairwells.
  • Each apartment has a large hallway.
  • Whereas perhaps 80% of the apartments at Unité d’Habitations are double-sided and two storey, all Alton West Point apartments are single level and two-sided.
  • The service riser is beautiful.

During his time as an architect at the London County Council, Colin Lucas was also responsible for these two identical buildings.

Somerset Estate, Battersea

Somerset Estate, Battersea

Three floors of four two-bedroom apartments alternate with one floor of one-bedroom apartments. Apartments are arranged in a pinwheel arrangement, but split two to a side by the elevator lobby that has a single fire escape stair at one end, and a laundry drying room and garbage chute room at the other. This lobby is naturally ventilated and daylit. It develops the configuration of the point blocks at Alton West. Here’s a two-bed apartment plan.

And here’s what the kitchen looks like. The column from which everything below it in the plan above is cantilevered, is just out of the picture. Not shown in the plan above is the small window above the cooker, made possible by the pinwheel arrangement.

For about five years, I used to live on the 18th floor of Selworthy House in Battersea. I can testify to the solidity, liveability and humanity of these buildings.

Selworthy House

The view is also very nice, but that’s just an accident of history.

view of london from selworthy houseWhen these buildings were built, nobody valued views, especially those over Battersea, Rotherhithe, Wandwsorth or Camberwell.

rainbow over batterseaWhat impresses me most about the design of these buildings is how, by alternating three floors of two-bedroom apartments with one floor of one-bedroom apartments, Colin Lucas managed to make something special out of what must have been a very constraining brief. He did not have to do that.

These eleven buildings do not receive any mention in the history of post-war British architecture. They probably never will.

  • As part of the British government’s thirty-year war against its own people, the idea of social housing as a government obligation has been being erased from the consciousness of the people.
    1. Social housing has had its name changed to the less-loaded ‘affordable housing’. (The current mayor of London is at present attempting to redefine affordable housing as rents at 80% of market rent.)
    2. Whether past or present, highly-visible social housing is frowned upon. It is amusing to see how photographers contrive to omit the Somerset Estate towers from photographs of the (then) Richard Rogers Partnership’s Montevetro. Here’s a page of google images of Montevetro. This next image is from RSHY’s website.
      rogers stirk harbour young Here’s what looks like a planning application site elevation. Anything unpleasant is only shown in outline. One can almost hear the planners say “No higher than those hideous towers and you must respect the listed Church of St. Mary.” I have no respect for Richard Rogers or Montevetro.montevetro
  • Meanwhile, on the other side of town, Trellick Tower by Ernö Goldfinger is iconified as a Brutalist poster building by a famous architect in much the same way as PJ’s UdH is.Trellick-Tower
  • Robin Hood Gardens has people fighting its cause just as much for it being an important building by famous architects Alison and Peter Smithson as for any social significance it may once have have had. For the government, this is the rub – the very idea of highly-visible social housing is anathema.

ROBIN HOOD GARDENS

  • Part of this ongoing stealth campaign to discredit social housing is to encourage people to think of Brutalist architecture as nothing more than a dated stylistic choice.
    1. Any social worth (such as additional floor area) those construction choices may have generated is actively overlooked. Off-form concrete was honest about diverting money away from cladding and finishes and towards more useful parts of a building.
    2. It is easier to brand Brutalism a stylistic choice if it is associated with famous architects. We’re used to that as a concept.
    3. I suspect the Lucas towers are particularly reviled because that one extraneous design decision of the 3+1 repeat makes them very PROUD buildings. Once upon a time this conferred DIGNITY, but nowadays it seems to represent audacity.

Architecture Without Architects

Architecture Without Architects is the title of a book by Bernard Rudofsky, published to accompany an exhibition of the same name at the Museum of Modern Art from November 1964 to February 1965. I first learned of this book when I was a student and in love with the idea of architecture. I thought the images charming and remember being shocked at the apparent blasphemy of the title.

Architecture Without Architects

If you’ve been following my posts regarding The Autopoiesis of Architecture, you’ll know that Mr. Schumacher is claiming it is theoretically impossible for architecture to exist without architects. Vernacular is for losers. Perhaps he’s right, and Mr. Rudofsky and his provocative title are wrong. But there’s more at stake than competing claims over the use of a word describing a concept. Rudofsky’s basic premise remains valid: It is possible to have a built environment that embodies man’s intelligence and humanity, and without involving architects. If you accept this, then you have a problem. Ask yourself: “What is it then that architects actually do? What is it they actually sell?” Get up to speed first, then read on.

Architecture Without Architects had been out of print since 1980 but is now in print again. I’m glad. I’m glad because the book’s message is also a primary theme of this blog – as can be seen from the beginning of the preface.

Architectural history, as written and taught in the Western world, has never been concerned with more than a few select cultures. In terms of space it comprises but a small part of the globe – Europe, stretches of Egypt and Anatolia – or little more than was known in the second century A.D. Moreover, the evolution of architecture is usually dealt with only it its late phases. Skipping the first fifty centuries, chroniclers present us with a full-dress pageant of “formal” architecture, as arbitrary a way of introducing the art of building as, say, dating the birth of music with the advent of the symphony orchestra.  Although the dismissal of the early stages can be explained, though not excused, by the scarcity of architectural monuments, the discriminative approach of the historian is mostly due to his parochialism. Besides, architectural history as we know it is equally biased on the social plane. It amounts to little more than a who’s who of architects who commemorated power and wealth; an anthology of buildings of, by, and for the privileged – the houses of true and false gods, of merchant princes and princes of the blood – with never a word about the houses of lesser people.

The situation Rudofsky described in 1965 is now much worse. The “houses of true and false gods, of merchant princes and princes of the blood” are now those of ASSORTED DICTATORS, DESPOTS AND (OTHER) DEVELOPERS. Forgive my shouting. Rather than have this post become a rant about that, I’ll let Architecture Without Architects speak for itself of the intelligence and humanity of an architecture without architects.

Figs. 16, 18: One of the most radical solutions in the field of shelter is represented by the underground towns and villages in the Chinese loess belts. Loess is silt, transported and deposited by the wind. Because of its great softness and high porosity, it can be easily carved. In places, roads have been cut as much as 40 feet deep into the original level by the action of wheels. In the provinces of Honnan, Shansi, Shensi, and Kansu about ten million people live in dwellings hollowed out from loess.
The photographs show settlements of the most rigorous, not to say abstract, design near Tungkwan (Honnan). The dark squares in the flat landscape are pits an eighth of an acre in area, or about the size of a tennis court. Their vertical sides are 25 to 30 feet high. L-shaped staircases lead to the apartments below who rooms are about 30 feet deep and 15 feet wide, and measure about 15 feet to the top of the vaulted ceiling. They are lighted and aired by openings that give onto the courtyard.

“One may see smoke curling up from the fields,” writes George B. Cressey in his Land of the 500 million: A Geography of China, even though there is no house in sight; “such land does double duty, with dwellings below and fields upstairs.” The dwellings are clean and free of vermin, warm in winter and cool in summer. Not only habitations but factories, schools, hotels and government offices are built entirely underground.

More From Less: The Principle

Here’s some outdoor space. Judging by the colour of the brick, the teapot, and the underused barbeque in the corner, it looks like we’re in England. The peripheral plants are doing their evapotranspiration thing but those benefits won’t be needed much when the average summer temperature is 22°C (71.6 °F).

small-outdoor-space-plantsThis outdoor space is enclosed by masonry on two sides and (almost certainly) timber on a third so any uncomfortable wind is probably blocked – along with any welcome breeze. We can’t tell the orientation from this image but, on evenings either side of summer, the thermal mass of the walls and paving will most likely make it possible to remain in this space for longer before someone suggests it’s maybe time you all went inside. But being outdoors is nice. There are many things we like to do outdoors whenever we can. The outdoor space in this next image seems to be in a climate that gets quite warm and, judging by the bamboo and the banana tree to the right, possibly quite humid as well.

Wooden-floor-outdoor-space Here, we can sit, eat and cook in this space, and even have a nap if we want. There are no walls and the floor is timber so there’ll be no heat retention due to thermal mass. The outdoor fireplace is probably something to look at whether functioning or not but it may help keep insects away. The absence of walls will allow any cooling effect a breeze brings. In this next image, one is protected from the wind and outdoor ambient temperature in this  space which is external to the main building aesthetically, constructionally, and conceptually – so let’s have a barbeque then!

fox_hill_web_024 This space can be used when it’s not desirable to be outdoors, even if standing next to a source of heat. Basically, we’re still inside. It’s the barbeque that looks out of place. Indoors and outdoors remain very separate, but at least we have a better view of the outdoors.

This is an unsponsored link to the full range of Viking barbeques. May as well.

viking barbeque

A whole industry of conservatories and big glass doors and windows has developed to allow people to have a better view of whatever outdoor space they have even if it has to be appreciated next to a fireplace. Nice window!

376221532_bb56cde250_oMoreover, a whole universe of architectural endeavour has arisen to give the impression the outside of a building is really an extension of the inside, even if (or perhaps especially because) it can’t be used for most of the year.

Pawson_House_London_by_Catherine_John_Pawso_CubeMe2 The outdoor space in the image above benefits from wind protection and the high-mass surfaces will re-radiate absorbed heat in the evenings to extend the period of comfort further into the evening or autumn.

This next image is a photo of a Japanese house – actually it’s no ordinary house, it’s  Katsura Palace doing the inside-outside thing that so impressed FLW and many other pre-21st and last-21st century architects such as John Pawson, designer of the space in the photo above.

As far as the internal environment is concerned, its a bit like this next space – a room without walls. Let’s play “Spot the Viking!” Both rooms are most certainly lovely to be in when the weather’s nice but, when it’s not, you really don’t want to be there. In passing, these two images show how thermal comfort is blind to notions of visual beauty. I’ll have more to say on this later but, perhaps one day there will be such a thing as tactile aesthetics – the beauty to be found in a physiologically comfortable internal environment.

outdoor-kitchen-in-log-home1 But other than providing an alternative place to be when weather permits, what’s in all this for the indoor space? Nothing. We need to make a distinction between outdoor space that is no more than outdoor space the other side of a door or window, and outdoor space that also modifies the environment on the inside.  Consider this balcony. It provides the benefit of additional space and the effect of adding value to the apartment but it will also provide the summer benefit of shading the glazing and modifying the thermal environment of the that opens onto it – especially if the balcony faces south. 

Photo-Home-Tour-Azure-Balcony-lo-res-2013

The thing about More From Less is that space that’s not fully enclosed and conditioned can substitute for indoor space some of the time and because it’s not enclosed to the same degree as internal space, can also provide climatic benefits for that internal space. In other words, space that isn’t constructed or detailed for 100% climatic adjustment can still passively benefit the internal environment.

Not all balconies, courtyards or rooftops have a positive passive effect. The courtyard of Ando’s Sumiyoshi House in Osaka will be hot in summer and cold in winter. Please visit this post on contraHABIT for a internal environment analysis of this house in terms of thermally active surfaces and flows, thermal comfort, natural ventilation, cross ventilation, stack effect and high mass cooling. (Nice work Taylor and good luck for the future!)

6_lge

If not much in the way of climate control, Ando’s Sumiyoshi/Azuma House is a reminder of how the Japanese manage to aesthetically, if not always physically, appreciate a certain poetry in ambient temperatures lower than many of the rest of us might. When it gets too cold for their houses to do the inside-outside thing, you’ll find Japanese in warm clothes huddled around a source of heat before getting quickly beneath a stack of futons in a shiveringly cold rooms at night.

kominka

In this plan of a traditional farmhouse, Room 3 has an irori (see below) as a source of heat and most winter activity would take place in that room. Room 3 has no external walls. The remainder of the house is being used as a thermal buffer.

800px-Japanese_Traditional_Hearth_L4817 The vernacular housing of many countries will have similar examples of people retreating into the parts of the castle, mansion, or house that can be heated the most economically and efficiently. This sounds familiar. There might be something we can learn from this in terms of seasonally differentiated construction. Why should all of a house have to be used in the same way all the time and all through the year? After all, we all enjoy balconies but don’t expect to use them all year round. You’ve seen this plan before in It’s Not Rocket Science #7: Evapotranspiration. It’s the plan of an Egyptian courtyard house from around 3,000BC.

p143

That post mentioned how cool air is trapped in the courtyard overnight to keep the spaces opening onto the courtyard cooler and cooler for longer into the day. It mentioned how this effect is reinforced by planting a tree in the courtyard to shade it. This works well in places with a large diurnal temperature difference.

cropped-meybod2.jpg This climatic benefit only arises because the central space is not fully enclosed. So if you’re going to read a book, or have a drink and a chat or possibly a nap, do it in the courtyard! Not everything needs to be done indoors all the time. The lesson here seems to be have two types of space. Climate permitting, the light structure can be dispensed with altogether.

???????????????????????????????????????????????????????????????????????????????????????????

The cave dwellings of northern China are another extreme example of this type of construction.

north china cave dwelling With these, there’s a heavy structure and huge thermal mass behind the building but this research shows that in front of the building it is still better to have a courtyard than nothing at all.

1-s2.0-S0378778801001451-gr4 This reminds me of Villa Vals (46°37’15.49″N,  9°10’51.36″E) which, it seems, is now a rental villa. Its famous courtyard faces WNW – and another mountain. In this photo, we’re looking south, down the valley.

1260367142-1villa-vals-search-7899 I don’t know if the courtyard at Villa Vals has a sufficient degree of closure to be a courtyard with any climatic benefits, but the principle is to have an outdoor area with a fair  degree of enclosure fronting a structure with a higher thermal mass. The actual materials  depend upon what’s available and the relative amounts of structures depend upon the climate. Temperate climates are easier to handle.

latapie planThe rear half of the Lacaton & Vassal’s Latapie House is not a courtyard, but nor is it a covered porch added onto a house. And nor is it merely a covered part of the garden. Whatever it is, it is an inexpensive structure with the beneficial effect of extending the range of usable temperatures of what could have been conventional garden, further into the evenings and colder months. It ameliorates wind and temperature extremes and modifies the environment on a seasonal as well as a daily basis. It is not a courtyard but an inexpensive addition that produces climatic advantages not unlike those producedby courtyards in hot, arid climates – except that the object is to trap warmth, not coolth. 

latapie

As is obvious from the plan, the house is not large, but this inexpensive addition permits a luxury of space and use that would not have been possible with more conventional materials and construction. The occupants have more options in terms of when and where to do what they do. Environmentally, the building has not used a wealth of resources. It is trapping heat to make its own volume more habitable and, even when it is unused, this effect carries over to thermally benefit the “main” building.

An earlier post mentioned how Lacaton & Vassal used this same principle in this project for an extension to a high-rise building.

interior view

This is a link to a paper titled “Building Performance Evaluation of Newly Built Greenhouse Residences in Terms of Heating Energy and Thermal Comfort”. These are some of its conclusions:

  •  A greenhouse saves about 25% on annual heating energy demand compared to a residence without greenhouse 
  • It is possible to optimise a GHR in such a manner that the greenhouse zone is usable for up to 750 hours a year, during 10 months

outdoor usage

  • The largest increase in usable time of the greenhouse zone compared to the outdoor climate occurs during the summer period

20-26

  • A properly designed GHR does not exceed thermal comfort limits i.e. weighted overheating hours.
  • The most sensitive parameters are related to heat gains/losses and insulation.In conclusion, we can say that a GHR has benefits in terms of annual heating energy demand and usable hours of the garden zone; nonetheless, highly insulating is more effective as it saves more heating energy. If a GHR is properly designed it is possible to reduce the annual heating energy demand with an acceptable thermal comfort and usable outdoor hours. It needs to be addressed that a GHR has the benefit of the outdoor space, in comparison to other building concepts.

It’s a field of study that promises to pay off, particularly for buildings in temperate climates. In the past, people would enclose porches with lightweight structures in order to make more usable space. Well, in the future, more of what is called architecture just might have to include these lightweight structures that people will have to make the best use of whenever they can. And during extremes when that’s no longer possible, they can retreat into the core of the dwelling while the external structure serves to ameliorate that internal environment somewhat. Lacaton & Vassal are pioneers in that respect. It’s more useful than Sanaa elevating the communal circulation space to the status of architecture.

So what about this then? What’s going on here?

Seoul Light Section small

Seoul Light DMC Tower Digital Media City in Seoul, Korea combines technology and sustainability strategies to create a new model of super tall building design. 

A large central atrium spans vertically through hotel, residential and observation deck program areas to allow for penetration of natural light and air throughout the building. 

Air rises through the atrium in a natural “stack effect” and drives wind turbines at the crown of the building. Interior gardens at perimeter atriums act as “lungs” for the tower, providing air circulation and filtration for the varied functions.

0695-6

At 2,100 feet tall (133 stories), the mixed-use tower hosts a collection of green technologies, including solar panels, wind turbines, enhanced daylighting, and living walls. SOM anticipates that these strategies will reduce overall building energy use by 66 percent. “Original constraints on super-tall buildings were vertical transportation and structural requirements,” explains SOM design partner Mustafa Abadan. “Today, those requirements have become easier to solve with technological advancements, but sustainability needs to be addressed. We’ve shifted our priorities to environmental issues.”

Or how about this?

About halfway up the building at the hotel lobby, the more-traditional core is replaced by a 1,000-foot-tall vertical void. Roughly 60 feet wide by 100 feet long, the void is based on the principles of a solar updraft tower. Using the stack effect, air will be drawn into a collection area, where it will be heated naturally by the sun before it rises up through the tower to drive six horizontal-axis wind turbines, each 3 meters (about 10 feet) in diameter. SOM predicts that this “solar engine” will provide 3 to 5 percent of the building’s overall energy.

You can read more here, but I can’t help but wonder if this isn’t a lot of trouble to go to for a 3%–5% energy gain?

0695-5-600x792

Enclosing space is expensive. “More From Less” is about inexpensive ways that space can be enclosed for limited amenity and limited climatic/energy benefit. Using less materials or construction or whatever BECAUSE it is better to do so. It’s quite simple really. This building of SOM’s does not feature lightweight steel framing and polycarbonate sheeting on the outside and which might have worked just as well. Instead, what we have is a large central void almost fully enclosed by some rather serious (and seriously contorted) structure. If the object is to create a column of air that can be heated, then this is over-construction.  Why put a column of air in the middle of a building and then try to heat it from the outside? What were SOM thinking? I can’t believe an externally-mounted lightweight structure would not heat the air better and channel the hot air upwards just as effectively. Does it really take some swishy glass curves to make hot air go up? I find this building retrogressive in its use of maximum means to achieve not very much. The fact it won a a 2010 Chicago Athenaeum Green Good Design Award and a 2010 Eco-Structure Evergreen Award is deeply disturbing.

This is a design study for a building that I did, way back in 1995, exploring the poetics of energy-saving technologies. The point was to make PV panels look all sexy by using technological grandstanding to make allusions to Nature. In other words, the point was to make a big show of representing renewable energy rather than concentrating on actually generating it.

mainhouseTwo huge triangular PV arrays are each mounted on three hydraulically-extendable columns that extend and retract to enable the orientation and inclination of the arrays to track the sun to a greater extent than would otherwise be possible. The array planes are always parallel except at around midday and just after sunset, when hydraulic manoeuvring has to rearrange them so the one at the back is now at the front, not unlike a butterfly refolding its wings.

The entire point of this study was to give poetic representation to renewable energy devices without regard for the initial cost, the amount of embedded energy or the amount of energy actually produced. It’s bullshit really – using devices of virtue for an architecture of decadence. It’s not unlike the eating of songbirds or the eyes of peacocks, but it’s where we’re still at.

It’s Not Rocket Science #7: Evapo-transpiration

Speaking of gardens in the sky, I once lived in an apartment building that had one on the 25th-floor.

It was just a couple of floors missing from the building and wasn’t really integrated with any other space. It had ponds and palms and even a bit of grass and, on the whole, there was probably more evaporation than transpiration happening.

Transpiration occurs during photosynthesis when the plant’s pores (called stomata) on the underside of leaves open so the plant can intake CO2 and a little bit of water escapes when they do. This escaping water functions to transport nutrients from the roots to the leaves and also to cool the plant in hot weather.

dubai temperature and humidity

Dubai is hot and its humidity ranges between 40% and 85% with an annual average of around 65%. However, with summer temperatures in the 40s, the air can hold an enormous amount of moisture and still not feel humid. Singapore, by contrast, has consistently lower daily temperatures and consistently higher humidity. Plants don’t need to work as hard there to transpire. This is a good thing since transpiration would only add to the humidity.

image001

In my garden in the sky, the well-watered plants were shifting the moisture from their roots to their leaves and from there into the air. It did feel perceptibly cooler if there was no breeze or a very slight breeze. Air cooled by evapo-transpiration needs to be kept from moving away.

p143

This is the plan of an Egyptian courtyard house from around 3,000BC. 

This arrangement provides drops in air temperature of 10-20°C (18-36 F°) at night. As evening advances, the warm air of the courtyard, which was heated directly by the sun and indirectly by the warm buildings, rises and is gradually replaced by the already cooled night air from above. This cool air accumulates in the courtyard in laminar layers and seeps into the surrounding rooms, cooling them. In the morning, the air of the courtyard, which is shaded by its four walls, and the surrounding rooms heat slowly and remain cool until late in the day when the sun shines directly into the courtyard. In this way, the courtyard serves as a reservoir of coolness. [Natural Energy and Vernacular Architecture: Principles and Examples with Reference to Hot Arid Climates]

This is the town of Meibod, Iran. The courtyards are filling with the cooler night air. Notice how each of those courtyards also has a tree? After sunrise, photosynthesis will kick in again and the (denser) cool air held in the courtyard will be supplemented by air cooled by evapo-transpiration to extend the cooling effect further into the day. The shade provided by the tree will extend that effect further still. It’s a simple arrangement that works.

Less rural Persian gardens utilise the same principles but with more importance on visual beauty than cooling performance. As is the way.

Like the Persian courtyard house and its tree, certain combinations of plants and buildings work well for certain climates. Planting trees to shade east and west walls in summer is usual for mediterranean climates. In the cool temperate climates, deciduous trees shade south walls in summer yet allow light and warmth in winter. These uses are good but limited to instances where there is unbuilt land for those trees that are part of the climatic strategy. 

High-rise buildings usually occur in places where land is densely developed and trees are scarce. In any case, buildings these days tend to be taller than trees. If we’re going to put trees onto buildings, then we have to think about what it is that trees can do for a building and its occupants that some other type of solution – such as a shading device – can’t. We need to think about this because buildings and enclosing space of any kind is expensive. If we’re going to mess with the building to include them, then plants in general and trees in particular have to have some sort of quantifiable and unique benefits for the building and its occupants to justify their presence. Otherwise, it’s better to just go plant some trees somewhere, preferably nearby. 

solaris_fusionopolis 2b_r210612_a1

Yeang’s Solaris located in Singapore here at approx. 1°N is a case in point. The plants on the high end of the building face south and can’t provide much in the way of shade, the plants on the east and west shade every third level whilst, from the treed terraces on the north side of the building, it’s possible to look out over more trees!  I just don’t think these trees are there for their benefits of shading and evapo-transpiration.

Let’s move to Milan now and check out Bosco Verticale more closely. The architect says

On flat land, each Bosco Verticale equals, in amount of trees, an area equal to 10,000 sqm of forest.
The Bosco Verticale is a system that optimizes, recuperates and produces energy. The Bosco Verticale aids in the creation of a microclimate and in filtering the dust particles contained in the urban environment. The diversity of the plants and their characteristics produce humidity, absorb CO2 and dust particles, producing oxygen and protect from radiation and acoustic pollution, improving the quality of living spaces and saving energy. Plant irrigation will be produced to great extent through the filtering and reuse of the grey waters produced by the building. Additionally Aeolian and photovoltaic energy systems will contribute, together with the aforementioned microclimate to increase the degree of energetic self sufficiency of the two towers. The management and maintenance of the Bosco Verticale’s vegetation will be centralised and entrusted to an agency with an office counter open to the public. architects website

All good. The balconies are generous and, as is the Italian tradition, their construction looks solid and made to last.

Bosco-Verticale-External-568x340

On his website, you can see that the architect has thought of the types of plant suitable for each facade orientation. I should hope so.

06-Bosco-verticale

The system of irrigation has also been thought through. Again, as it should.

03-Bosco-verticaleI wish the architect and building good luck. It seems a genuine attempt to fuse vegetation a building in a meaningful way. Tall buildings do strange things to wind so there are still unknowns such as how the trees will cope with wind not necessarily coming from the side and rain not necessarily falling downwards but fortunately, Milan is not a very windy city. The trees will tend to grow outwards towards the light so let’s hope overhanging branches aren’t allowed to become dangerously picturesque.

wind_speed_windSpeed_mph

The benefits of all these trees are shown graphically in the diagram below. We shouldn’t be too amazed by any of this. The trees will just be doing what trees have done for the past 400 million years (and, apart from the last 200,000 years of that, for no-one’s particular benefit). Of all the benefits shown, only the noise reduction effect is debatable but even if there is no great tangible reduction in the amount of noise, I believe that at least not being able to see the noise source does go some way towards lessening the awareness of noise. The rustling of leaves may even create a masking white noise. What about birds? Depending upon the type, the time and the amount of noise they make, birds may or may not be welcome. Birds can also be rather messy, but that’s their nature.

08-Bosco-verticale

The green box in the diagram above suggests that the experience of this building will be akin to that of being lost in a forest with its own microclimate, and isolated from the sights and sounds of the city outside. To a certain extent it will be, or at least it will be more so than most of the other buildings around. But what about evapotranspiration?

relative_humidity_percent_pct (1)Let’s ask weatherspark what the humidity in Milan is like.

The relative humidity typically ranges from 45% (comfortable) to 95% (very humid) over the course of the year, rarely dropping below 27% (dry) and reaching as high as 100% (very humid). The air is driest around March 23, at which time the relative humidity drops below 55% (mildly humid) three days out of four; it is most humid around November 1, exceeding 93% (very humid) three days out of four.

Thanks weatherspark. The blue line is the average daily humidity and seems rather high for transpiration to be considered a benefit. Milan has a Mediterranean-type climate with warm dry summers and cool winters with rain. It’s pleasant. The heat and noise of the city might irritate in summer on a humid day and so an amount of trees equivalent to 10,000 sqm of forest, a bit of evaporative cooling and various other benefits including biophilia in all its forms, is totally welcome. However, keeping it real,

it would be more welcome if the buildings did not stand in a park! 

A lot of money has been spent so that the owners of property within a high-rise building can have one of the attributes of land – the joy of having significantly sized trees outside one’s window. This type of joy does not come cheaply in a city. These plants have various marginal microclimatic benefits but their main appeal is just that. They aren’t exactly a part of the food chain or the waste cycle as they would be in truly integrated ecosystems like those that insects and plants manage to create for themselves. These trees are – I’m afraid to say – “Eco Deco”. There! I’ve coined the word and now offer it to the world.
