Lumeta PowerPly PV Panels

So I have been studying for my LEED AP exam lately, so my interest was peaked when I came across this article online. Apparently, DRI Energy has come out with a product called Lumeta PowerPly which adheres directly to the roofing membrane instead of being mounted on an expensive and heavy roof structure, which is one of the prohibitive cost factors in the implementation Photovoltaic Panels. I imagine that this application will have less of a yield because it is fixed to the angle of the roof than rack mounted systems, which can be tuned to face an optimal angle or even rotate and tilt to follow the sun.What is lost in yield I imagine can be made up on roofs that would normally not be able to handle PV panels (such as curved roofs and steep pitches). In addition, I would worry that since this bonds to the roofing membrane, if there is a membrane failure the PV panels will need to be replaced as well, instead of being able to be removed and remounted in a traditional system.

I knew that this technology was out there, but I was unaware that it was already being marketed. I think that this kind of application process could definitely help bring PV panels and solar energy use to projects that would normally not even consider it.

(And in case anyone is wonder, no they aren’t in rainbow colors and are not actually made by Lisa Frank)

Article: As seen at the Apple Store …

The New York Times ran an article about an architect who used a glass stair in his home to open it up and create more light. Glass stairs are nothing new to commercial architecture – they’ve been around for many years before Apple* built one in their iconic SoHo store in NYC, but they are relatively new in residential construction. Part of the reason for this is that the structural components for a glass stair like the one in the article (a concealed steel structure) are not commonly used in American stick frame architecture. Wooden stairs, though much less transparent, are less expensive, and thus tend to be the the de-facto choice, even under skylights.

The thing that i find interesting about this article is the introduction of typically commercial elements (glass and steel) into a victorian townhouse. I noticed that the article makes no mention of the historic preservation / adaptive reuse element of this story, nor does it question the merits of completely transforming a house of this age in this manner. I’m not saying that i think it was the wrong move (i don’t know the full scope of the architecture) but from the accompanying images it seems as if the remodeling has thoroughly removed any traces of the house’s former life. Such a drastic move as this always makes me wonder if there was a more subtle way of adapting a house such as this to the needs of the occupants?

* – It should be noted that Apple’s iconic stair is a self supporting glass stair – there are no hidden steel support stringers, the glass is supported by a glass wall below.

In defense of Architects

This past weekend the Washington Post ran an article in their magazine describing one man’s trauma renovating his kitchen. It has some very negative things to say about the architect, the contractor, and the building process as a whole. It is obvious that there is blame to go around. Yes, the architect made poor design decisions and the contractor had his errors as well; but speaking as a member of the profession, I feel that the greatest problem here is with the public conception of what is the job of an architect.

It is very clear what a contractor does. They interpret the architect/designer’s plans (or owner’s description) into a real built environment. Thats it. They may hire out subcontractors, manage time, and coordinate, but their number one job is to build.

An architect’s number one job is to plan and oversee, not, as commonly believed, to design or create. Yes, part of the planning process is the creation of the original design with the input of the owner, but the real job of an architect (or at least a construction/production architect) in the US today is to make sure that end result conforms to code, performs within reasonable expectations (doesn’t leak, has adequate HVAC ,has the proper plumbing hookups, is structurally sound, etc – the actual design of which may be outsourced to engineers depending on the size of the project), and is to the satisfaction of the owner. It is not to come in under budget or ahead of schedule, or even on time. These are commendable goals that every architect should strive for, but they should not supersede the needs of a building that just WORKS. This management roll is why an architect is/should be involved from the day the project begins site selection until the owner has the keys in their hand.

All of this sounds fine, until, like the tinkering of a a mad chemist, you combine a contractor and an architect. The ensuing relationship may (albeit very rarely) be one of silky smooth communication and efficient construction, or (not as rarely but still not usually) an explosive clash of interests and egos the likes of which the senate chamber has never seen. Usually, the result is a sometimes friendly, sometimes adversarial relationship where the contractor spends a lot of time undoing and redoing work. This is mostly due to a breakdown in communication and some key issues that are overlooked 99% of the time. Without going into the in depths mechanics of construction administration, it will suffice to say that a contractor must submit everything to the architect for approval before it is built, while it is being built, and after it has been built. This process usually has holes due to time or budget demands and a desire on the part of the contractor to increase their profit. Contractors want to have as little time spent waiting for approval as possible and owners tend not to want to pay architects to continually visit the job site and oversee the work of contractors. Because of this, details like window flashing (waterproofing at exterior surface penetrations), movement joints, insulation, and anything else that gets hidden tend to get constructed improperly. There are many reasons for this (lack of skill in the installers/staff, errors in the documents, a desire to cut corners, etc) but as far as the owner is concerned they all look the same: “perfectly good work” being torn out because some “fussy” architect has to have everything his way. This isn’t to say that there are some cases where the architect is being overly cautious/anal retentive, but in the sad state of modern practice, it is usually the architect trying to prevent themselves from being the subject of a lawsuit when your new skylight leaks all over your original mid-century modern rug and ruins it.

Something else that is easily ignored is the power of the purse. Owners should never pay contractors without pay authorizations going through the architect, and these should be based on percent of work completed, not an arbitrary timetable. This allows the owner to accurately pay for work rendered; this way incase there is a cessation of work – for natural or legal reasons – the owner has not overpaid the contractor. This goes double for the end of a job, the owner needs to hold off on the final pay authorization until the architect has ran a final punch-list (a checklist of issue that need addressing) and can vouch that the project is completed.

All of this goes back to a post I wrote at the very start of this blogging experiment – courses in the bureaucracy and business of home repair/renovation for homeowners just like the mortgage seminars some home buyers must take. Owners do not need to be infinitely involved in the day to day issues of construction, this is one of the reasons to hire an architect or a construction manager, but they should know be comfortable knowing that an architect may seem to be wasting their time but they are really protecting their interests. Such seminars could, in a single half hour session, help to clear up these misconceptions and also help home owners to realize the value added by hiring an architect in the first place.

The author closes his article stating that before you renovate, make sure you know more about construction than your architect or contractor. This is wrong, owners do not need to know how things work, what they do need to do is to be prepared for their 1 month renovation to stretch on for a year. It is essential that an owner understand that no time estimate is definitive and that in the end it is better to wait for a new kitchen that functions than to have the project delivered on time and be of sub-par construction. The old adage IS right: good things come to those who wait.

She’ll be riding on the Metro when she lands …

Today The Washington Post reported that the rumors of the demise of the Dulles Metro Extension were greatly exaggerated. Of course, this does not mean that the funding is free and clear, it just means that the project has not been scrapped and it will continue, with certain requirements to be met.

For those unfamiliar, this project is a rail extension for the WMATA run METRO’s Orange Line. The new line would run out to Dulles Airport, the main international terminal for DC, which is currently only reachable by Bus, taxi, or personal vehicles. This extension would also service the towns between the end of the orange line and the Dulles Airport, a heavily developed stretch of land that currently has very heavy commute times into and out from the city.

This is some of the best news for Northern Virginia and the DC metro area in a long while. There has been rampant speculation in the housing and development markets in regards to locations of future metro stations; this was all in great danger of collapsing after some recent articles warning of the possible death of the project due to federal oversight and fears of a bloated budget. If the speculation did not pan out, this could have triggered another horrible fall in the local housing markets, and could have meant many more foreclosures. Also, the extension will provide greater rail access farther west from the city than is currently available and may help alleviate some of the beltway and commuter traffic. If this project is successful it will bring with it hope that commuter rail solutions to traffic in Northern Virginia could be a reality and that the fable purple line (a ring line around the city) might one day be constructed.

Organic Planning?

Recently I have made a number of posts regarding green buildings and the paradigm shift which will be necessary if we are even going to have a truly green architecture (see posts here and here). I bring this up again because i recently read two different articles online from two different architectural professionals from two different cultures, Martha Schwartz – a Boston & London based landscape architect and Harald Bodenschatz – a professor of Sociology and Planning in at the Technical University of Berlin and they both discuss similar goals for a more environmentally friendly development. Schwartz focuses on the urban landscape and its development (or lack thereof) currently as opposed to in a truly green environment, and Bodenscahtz focuses on the development of inner cities and suburbia as sustainable growth tactics and in such a way to help the European city thrive.

While neither of these articles explicitly states my previously argued hypothesis (that in order to be a truly sustainably designed society we need to increase our population densities and thus maximize our transportation schemes), both provide intellectual support to my arguments. Without a new 21st century version of urban renewal – one which is culturally, environmentally and economically sensitive – we will never be able to sustain our growth and development. This collapse in infrastructure is one of the issues facing us today, and it is potentially more threatening than global warming, rising oceans, and food shortages. With more people in the suburbs there are more cars on the road, the more cars the more wear on the roads. The more cars, the higher the demand for and thus the higher the price of gasoline, and the higher the demand for gas the less money available for other “necessities.” Greatly improved mass transit systems could alleviate the strain on our fuel supply and roads, while slightly increased mass transit systems but planned suburban clumping and urban densification could easily have the same impact.

Article: A bicycle built for exclusion?

The SmartBikeDC System

This past Sunday, The New York Times ran an article about bike sharing coming to DC (as did The Washington Post and The Associated Press.) I find it interesting that I had, not 4 days sooner, blogged about the Parisian and Viennese bicycle sharing programs.

The program, named SmartBike DC, is only currently going to be implemented in the North West of the District; the article mentions that there will only be 120 bikes and 10 stations in the system, but that it is hoped that it will grow to over a 1000. I applaud this move by the district and its partnering with clear channel which has made this a possibility. More government services should look to this as a test of private sponsorship as an alternative to privatization. In addition, I hope more bikes and racks are swiftly forthcoming, the more capacity this system has the greater the ridership and impact it will have.

Unfortunately, I worry that the system is not in place for those who could use it the most, the residents of NE and SE, many of whom are WAMTA bound and to whom $40 a year unlimited use rental fee will be much more reasonable than the $40 weekly Metro passes or the $11 weekly ($44 monthly) unlimited bus passes. In addition, besides the Shaw neighborhood and the Reeves Center (which is close but not in the heart of the columbia heights gentrification), none of the other 8 bike locations are in non-gentrified non-majority white neighborhoods. Furthermore, of the few images of people that are present on the website, none seem to represent people of color. To me this seems to reek of a further separation of transportation methods amongst the district residents. White middle and upper class people in NW will now take cabs, the metro, and bikes, while the working poor in NE and SE will be forced to rely on the same failing bus system that they have in the past. This makes me wonder if this whole endeavor is in some way an attempt to kowtow to environmental pressure from the middle and upper classes and not a means of democratizing transportation.

Article: Gehry goes Geometric!

Frank O. Gehry‘s new building at Princeton University – the Lewis Library – is nearing completion. Princeton’s website has an article describing the new building and giving us a sneak peak inside.

I hate to prejudge this building, but from the pictures, I worry that this is going to be even worse of an occupant experience than MIT’s Stata Center. The bright contrasting colors of the interior and the sharp dramatic angles seem to go one step beyond the Stata, which looked like it was falling down, instead, the exterior of the Lewis Library looks like a jumble of child’s block swept under a rug and the inside looks like something from a medieval view of hell. In addition, from what we can see in the photographs and what has been installed already, there seems to be a lot of hard surfaces with little acoustic dampening (a problem at the Stata as well). The article makes the claim that the third and fourth floors of the building’s tower will be the quietest places on campus, but i have to wonder about the rest of the building. As far as the exterior goes, it seems to be a natural progression in Gehry’s work. The obvious influences are the Stata center and the disney concert hall as well, but there are more subtle influences here as well. I can see shades of Chiat Day in the volumetric massing and even some of his Gehry house in Santa Monica in the delaminating of the skin from the building and subverting of building conventions.

The thing that I find the most compelling is that when taken as a series this building, Bilbao, the Stata Center, and the Disney Concert hall you can see the progression of how GehryPartners designs – they create volumes and then wrap them in a skin. Bilbao and Disney are both skin-type buildings, Stata is a volume building. The Lewis Library is the closest thing to a hybrid showing both volumes of program and a steel wrapped skin. In two years, after this building has been open and inhabited for a while and has had its due in the architectural magazines we will see what the verdict is n this building.

Article: Un velo a day keeps the traffic away.

A Bike Station in Paris

Horns honking, cabbies swearing, streets filled with a slow moving mass of metal particles, pedestrians choking on exhaust fumes: Traffic.   Nothing says Urban center like a heaping helping of fossil fuel consumption, or does it?   Paris and Vienna have both rolled out free short term bicycle rentals (albeit at different scales) as a social experiment and attempt to reduce reliance on automobiles and ease traffic within the urban centers of these two European Cities (read about it here).

This is something that could work in the Old Growth Cities along the eastern seaboard of the US, as long as it is kept free for short term rides and deployed in massive numbers (like Paris). If you coupled this with a good commuter rail system this could make up for a non-extensive subway system: it would be a method of getting people from the rail terminus to their destinations. I can see this working like the zip car phenomenon, but in reverse. Instead of renting one on those rare occasions where you need to drive out of town, people could rent bikes daily (if there was enough of a supply) to go to and from work and the store. Of course this would not help commuters from the suburbs, but since it could alleviate casual car use amongst residents it would reduce some of the daily traffic. I could imagine NY, Boston, Philadelphia, Baltimore, and DC all benefitting greatly from this kind of program.

Article: New Urbanism, is it old hat?

Whether you know it by name or not, most of America has at one time or another come into contact with New Urbanism. This anti-modernist anti-sprawl post-modern offshoot which has been with us for almost 30 years, since the development of Seaside, Florida in 1980 held a conference in Old Town Alexandria, VA. If you understood the nature of New Urbanism, the fact that their conference was being held in one of the oldest downtowns in virginia is quite the irony.

New Urbanism stands for the creation of artificial suburban (and sometimes urban) downtowns and mixed use communities, something, which like the path to hell, is paved with good intentions. The problem I have always had with the New Urbanist movement is its non-organic nature. Communities get branded before they are built; house styles and strict zoning rules are pre-planned and approved by designers preventing any straying from the ideal image from entering the perfect new (sub)urban town. They also stand in direct opposition to Modernism; instead of drawing on both the strengths and weaknesses of modernism, they look to its failures and piece together historical pastiche architecture in an attempt to meet the needs of the present. Which is ironic, considering that modernism’s creed was to disregard all architecture that came before it to re-discover the natural forms of building.

On the other hand, I have great respect for what the movement did. It changed the discourse of suburbia and the planned town. No longer was planning a black and white contrast between Levittowns and Unité d’Habitations, but instead planned communities could approach multiple scales and occur both in and outside of cities. In addition it brought a focus back to mixing uses, developing ground floor commercial corridors with residents above and providing mass transit systems.

In recent years, New Urbanism has seen a wax and wane with the tides of fashion. More and more developers are using the New Urbanist Town Center model, but not applying the actual design philosophy to it. While at the same time the newest move by New Urbanists is to co-opt the language of Green Building, because by nature the New Urbanist system is very green friendly (if you disregard that most New Urbanist construction is on Greenfield/virgin sites). In my opinion this is a smart move; New Urbanism is appealing to local planning commissions and if it also helps bring about environmentally friendly design and planning that would be a boon for American Suburbia.

Article: Green Architecture is HOUSES!

This past week, the New York Times ran an interesting article about building green, not just in urban environments, but in suburbia too. The article deals with renovations as well as new construction and outlines some of the trials and tribulations home owners, architects, and builders can face when trying to build “green.”

In light of tuesday being earth day I wanted to take a moment and discuss Green Residential Building (I wouldn’t go so far as to say architecture). Lately we’ve been plagued with ads telling us that all we need to do to save the planet is:

  • change a lightbulb
  • drive less
  • use different soap
  • insulate our windows
  • switch to low flow faucets
  • use cloth bags instead of paper or plastic
  • etc

But in reality these are just stop gap measures. Yes, they help. Yes, they are better than not doing anything. But without creating a real paradigm shift, that is to say the way we eat, work and live, we will always be playing catchup. Not only do we need to eat foods grown locally, but we also need to eat seasonally and organically. We need to work closer to home and in buildings that do not constantly fight against nature to create ergonomically correct comfort level. Our houses need to not just take less, but also give back.

All of this is applicable the practice of architecture as well. Not only do we need low VOC carpets, but we need to design a space to reduce long term cleaning and wear on said carpets. It is not enough to choose low-E high transmissivity glass with a high diffusion and spread factors but we need to start actively using passive solar design and incorporating operable windows into buildings. White roofs to prevent urban heat islands are great, but green roofs which grow community gardens and have micro wind turbines to supplement building energy use are better. Even better still is to build sheltered into the ground such that there is no roof – only landscape. All of these possibilities are there, and they being debated and practiced on some of the more avant-garde Record Houses and buildings; but until the day that suburban tract houses are situated on their site to take best advantage of solar, wind, geothermal and other natural forces we will constantly be battling against the limits of technology.

The modernists, metabolists, futurists, hi-tech post modernists, et al had it wrong. The essence of the future is not to be found in crystals and made into glittering towers of glass and steel, but rather in the nooks and crannies of the world – the mythic caves of our ancestors – recreated as built landscape just as full of architecture interest and challenge as the glass spire, if not more.
