A Day in the Sun, part 1

The recent controversy surrounding the U.S. Department of Energy Solar Decathlon, which this year is being displaced from its traditional sight on the National Mall in Washington DC to a yet to be decided venue, prompted me to learn more about this event.  I took the opportunity to talk to my former FXFOWLE colleague Minnie Jan, who participated with her team FabLab in the Solar Decathlon Europe in 2010.

The Solar Decathlon occurs every two years, in Europe on the even years, in America on the odd years, and China is set to join in 2013. Collaborating with the Institute for Advanced Architecture of Catalonia (IaaC), the FabLab team produced a provocative design for a net zero home designed for a specific location, 2010’s site was in Madrid, with its particular solar resource and climatic demands.

FabLab’s design, a rounded, solar panel coated, passive house assembled from prefabricated wood glulam panels that form an ellipsoid rib-like structure, rises on piloti of sorts to create air circulation space beneath the home and to impact the site minimally. Simultaneously, as the passive design increases in efficiency, intelligent systems become increasingly effective in monitoring and controlling the home’s temperature and energy use.

Fascinated with the design, I asked Minnie Jan more about the process.

How was working in Spain? How different or similar was the construction methods?
As a first timer in Spain, I found it incredibly beautiful and full of history. However, Spain is extremely hot and humid during summer, so we considered those factors in figuring tolerances for a wood construction house. Solar Decathlon Europe is a competition between universities from all over the world, but all construction methods have to comply with U.S. codes or standard codes of the schools locales.

What was the most challenging aspect of the home design process, why?
There were three challenges: geometry, space, and construction.  A standard paraboloid section is suitable for solar tracking—per year per day. We deformed it to get optimal orientation for summer—narrowing to the west, eastward widening and flattening toward the zenith of 70 degrees. The freedom of the paraboloid prototype model allowed us to swiftly and smoothly adapt the prototype’s envelope.

The FabLab House’s rounded shape maximizes internal volume with minimal exterior surface, and it elevates off the ground upon three ‘legs’ in order to create a space under the house for certain outdoor activities. Using the house itself to create shaded space allows cooled air to be introduced into the home for natural ventilation. This simultaneously creates a comfortable outdoor space that doubles the living area. These three ‘legs’ are structural and provide special points for programs and technical equipment for ground level access.

Solar Decathlon Europe required all homes to be assembled and disassembled on site at Madrid in ten days. Thus we designed the house so it could separate into 20 parts and be transported by five trucks. All plumbing and electricity were also pre-designed to be connected on site and be fully functional.

What programs or equipment did FabLab use to prepare the design for construction?
The maximum solar incident radiation in Madrid informed the prototype, so we used Ecotec to adjust the building position to maximize the surface area for solar panels. Achieving a desired volume and footprint, we then used Rhino to construct a precise 3D model, including plug-ins such as Grasshopper, to produce the necessary information for digital fabrication.

Next post I’ll talk with Minnie more about the process of developing and building the FabLab house. READ MORE >

Land Use & Construction Law, part 2

Going into the lunch session, Richard Anderson, President of the New York Building Congress, was the keynote speaker. Construction spending continues to decline from its 2007-8 high point, but he anticipates it to increase slightly in 2011-12, but only if the MTA capital plan is fully funded at $7.6 billion in 2012. The overall health of the local construction industry remains highly dependent upon government work—62% of all NYC construction dollars in 2010. Investment in the metropolitan region’s infrastructure, with a particular emphasis on transportation (MTA) and education (SCA), is crucial to providing essential services upon which the City’s growth depends.

Where the trades come together - the construction site.

After lunch, a high-power panel convened on modernizing public construction law. I missed the second session, which focused on financing, but the first session targeted procurement laws and how they affect the construction of public projects at the State and local level.

Current state law permits only design-bid-build on State projects in order to prevent procurement abuses. These laws evolved to separate procurement from politicians, and they require award on fully designed scopes. Because projects have become increasingly more complex—with numerous specialists, BIM, and sustainability issues—the government needs a broader tool kit to match construction delivery methods to specific projects. The current sequential, fragmented process needs to be re-integrated to get the full team involved early on to reap the benefits of multiple areas of expertise. The existing system impairs collaboration, stifles innovation, and leads to greater costs associated with multiple contracts. 

According to Marla Simpson, Director of the NYC Mayor’s Office of Contract Services, changes in 2008 to the State law now permits use of “project labor agreements” in lieu of the Wicks Law (multiple prime contracts) in its procurement process, which has saved the City about $350 million, a figure confirmed by Paul Fernandes of the Building & Construction Trades Council of Greater NY.  Another procurement innovation, as noted by David Resnick of NYC Department of Design and Construction, is the Design and Construction Excellence Program, which bases selection for procurement of design services on quality rather than lowest bid; this fundamental change in procurement should be extended to contractors as well. According to Thomas Scarangello, Chairman of engineering firm Thornton Tomasetti, building information modeling has allowed them to deliver three-dimensional model information directly to contractors; as an industry, we are just beginning to explore the unintended consequences of this technical change.

John Miller, of legal firm Patton Boggs, presented his research of different procurement methods—design-bid-build; construction manager at risk; operator maintained—and selection methods—competitive sealed bids, competitive sealed proposals, qualification based. New procurement methods will have management implications. For one, public owners must be more flexible and accept a greater degree of team work. Bid proposals must be evaluated on several factors, not only price. Despite these hurdles, Commissioner David Perini, of the Massachusetts Division of Capital Asset Management and Maintenance, described how Massachusetts has revised its procurement regulations and attracted higher quality contractors, consequently experiencing both good team work and delivery of projects on schedule and on budget.

If New York State can implement legislation to change its procurement methods it is anticipated that construction costs would be reduced and higher quality projects achieved.  But any change that threatens the Wicks Law will have resistance from labor, unless it can be shown to increase construction jobs. Politics being the art of the possible, it will not be an easy task for Albany to change design and construction procurement laws.

Land Use & Construction Law, part 1

 

Towards the end of January, I attended the conference “Developing the 21st Century: in the Built Environment” at the New York City Bar Association. Despite the chilly weather, the panel drew about 100 people to the oak-paneled hall on 44th Street. The major points I came away with are:

  1. continued investment in mass transit is critical to economic growth and sustainability;
  2. climate change will result in rising sea level and potential liability for architects;
  3. legislative change on community benefit agreements or State contract procurement will not come anytime soon.

 

Nordhavnen: City Regenerative

James Parrott, Chief Economist at the Fiscal Policy Institute, predicted that we are gradually emerging from the recession with this year’s GDP anticipated to grow 3%. However, the end of the Federal stimulus package will highlight severe budget problems in New York State. Locally, high business taxes should be seen in a broader context since New York City has the highest value added and profit per worker in the country. It’s not surprising considering that our mass transit system fosters close proximity and high density. Clearly the government should focus on expanding and modernizing this infrastructure. 

Kenneth Fisher, of law firm Cozen O’Connor, and Margaret Stix, of the eponymous Margaret Stix & Associates, discussed the controversial agreements between developers and community organizations known as Public or Community Benefit Agreements (CBAs). Many community groups feel that development imposes burdens without offering benefits, which the Uniform Land Use Review Procedure (ULURP) does not address. In a CBA process, which is done outside ULURP, a developer may gain certainty while a community may gain such benefits as affordable housing, schools, parks, or “living wage.” A task force convened by NYC Comptroller John C. Liu, Public Benefit Agreements, studied NYC and nation-wide precedents before concluding that private agreements are legally unenforceable and the process can be flawed—CBAs  may undermine statutory public review process, they may lack nexus, public objectives may conflict, or they may even be coercive. One could implement private CBAs via restrictive declaration but only in addressing land use actions. Once public officials become involved the process must be explicitly regulated, as with NYC Economic Development Corporation projects, which can include broader social benefits. The task force recommendations of greater accountability, transparency, inclusiveness, consistency, fiscal responsibility, and enforceability have not been implemented. A scandal or a crisis may finally catalyze legislation.

FXFOWLE’s own Mark Strauss discussed the architect’s role in public policy and two founding visions of the American city—Alexander Hamilton’s “cities are necessary for our economic well-being” and Thomas Jefferson’s “cities are corrupting”—before explicating his “five Rs.” He supplied examples of the firm’s work illustrative of Re-development (Water Street), Re-integration, Re-thinking (Nordhavnen: City Regenerative), Re-positioning (Nassau Hub Redevelopment Plan), and Re-vitalization. Quoting Robert Ivy’s March 2010 editorial in Architectural Record, “The density of existing cities, and the interdependencies they provide, point to the best solutions, rather than designs for the most sustainable individual building and/or communities,” Mark emphasized the need to strategically invest in infrastructure and cities. Per person, cities produce ¼ the greenhouse gas emissions of suburbs because of a highly developed mass transit system. The mayor’s office, in a bid for increased sustainability, launched plaNYC, part of which targets reducing greenhouse gas emissions 30% by 2030 from 2005 levels. It was noted that buildings contribute 79% of carbon gas emissions in NYC, thus a large part of this challenge rests on the shoulders of the A/E/C industry.     

Thus, there is no doubt that climate change will impact projects! Michael Gerrard, Director of the Center for Climate Change Law at Columbia Law School, reviewed his studies of environmental legislation, including National Environmental Policy Act, State Environmental Quality Review, and City Environmental Quality Review (CEQR). While Congress questions the existence of global warming, litigation has established that greenhouse gases must be evaluated as “air pollution” in an Environmental Impact Statement (EIS). Gerrard noted that there is draft text to extend this quantification of emissions to the Environmental Assessment Statement process, and that the new edition of the CEQR Technical Manual has detailed metrics for greenhouse gas emissions. 

If that it isn’t change enough, the 2010 Sea Level Rise Task Force recommended that the State adopt sea level rise projections for the year 2100. This would classify areas at risk of coastal flooding, require evaluating projects in those areas to determine whether they should be classified as Type 1 (full EIS) or not, and recommend changes to building codes. Merely consulting FEMA maps is inadequate because they are based on past performance not future projections. Organizations such as the Securities and Exchange Commission and insurance companies are beginning to add disclosure requirements relative to risk of sea level rise. And closer to home, litigation has been emerging for failure to account for rising sea level, which will present liability for architects and engineers.
