INTERVIEW: Serge Appel Talks to Inhabitat About One Bryant Park

New York City’s 1 Bryant Park  building (also known as the Bank of America building)  is the greenest skyscraper in the world  and Inhabitat was fortunate enough to have the chance to speak with lead architect on the project Serge Appel  of Cook+Fox Architects , who helped it reach that illustrious distinction. The glossy glass structure  towering over Midtown Manhattan racks up the green points with rainwater cachement and reuse, greywater recycling, recycled and sustainable building materials, energy efficient building systems, and high performance glass which maximizes daylighting and minimizes solar heat gain and loss. Read on for our interview with lead architect on the project, Serge Appel to learn more about the design of this fascinating green building.
Appel: For me, the best part of this project isn’t a single element or technology but rather the chance to work with an incredible team of dedicated professionals all driven by the same goal. Having the backing of the Bank of America  and the Durst Organization  has made a tremendous difference in setting the bar high in terms of sustainable design. On top of that, each consultant on the team is top notch and fully engaged with the project.
Appel: Certainly the most difficult part of this project has been the intense and detailed coordination required for such a large and complex building. The vast majority of that has far less to do with the green elements than with the requirements of a major banking institution being built in the middle of midtown Manhattan post 9/11.
Appel: I’m still involved daily in almost all aspects of the project, from the spire detailing to quality control on the installation of the curtain wall. Even after several years, there’s always something exciting and new right around the corner – not to mention that One Bryant Park is not your ordinary office building. Even still, staying personally motivated and keeping a team of people working over many years requires a strong sense of ownership and responsibility, as well as a fair amount of patience. Fortunately, projects this large are always broken down into smaller pieces, each with its own bit of gratification.
Appel: They’re not exactly giant ice cubes, but the thermal storage system basically works like a “battery” for cooling. In the basement, there are 44 10-foot high, cylindrical tanks with water and a cooling coil inside. At night, when electrical production from the co-generation plant exceeds the building’s needs, we use that excess to run the chilling equipment to freeze the water in the tanks. During the day, the ice melts and provides cooling to the building. This shifts some of the electrical load from daytime to nighttime, which reduces the impact on an already stressed NYC electric grid.
Appel: Waterless urinals are pretty straightforward; from the point of view of the user, there is no real difference. We have them in our own office, which we moved into last year and is also LEED Platinum – the first in New York. Instead of flushing, the urinals have a special drain fitted with a cartridge full of a liquid less dense than urine, which “floats” on top and seals out odors. Like all urinals, they have to be regularly maintained and cleaned and the cartridge has to be changed on occasion.
Appel: Building green is not a trend, at least not in our minds. The idea of building green really is about building smarter, higher performing buildings which are considerate of the people who live or work in them. Like any other aspect of the building, the benefits need to be weighed against the costs. There were several items which just couldn’t be justified today. When we started the project, we were sure that there would be building-integrated photovoltaics, but the more we looked at the amount of electricity generated, the less it made sense. We also looked seriously at including a wind turbine – in fact, the building originally had two spires, one architectural and one for the wind turbine. We even set up an anemometer on top of the adjacent 4 Times Square and took a full year of wind measurements. What we discovered is that while there is sufficient “quantity” of wind, it isn’t consistent enough to make the power generated worthwhile, at least not at the current state of the technology.
Appel: The building is almost fully leased, and from what we have heard being green has made a significant difference. We are designing one of the tenant floors at the moment for fashion designer Elie Tahari LTD, and the green elements of this building were very important to them.
