Glass Buildings: The Energy Challenge
Tuesday, Mar 3, 2009
The all-glass high-rise tower is an icon of contemporary urban architecture. Developers seem to love the all-glass building as a beautiful object and tenants seem to respond to the panoramic views they provide. From a sustainability perspective, critics have begun to raise concerns and generate cutting edge discussions about the energy performance of such buildings at exactly the time New York City is weighing greener Building Code recommendations. It has been a major topic of discussion here in NYC in considering Building Code recommendations developed by a working group of the US Green Buildings Council NY Chapter. The March 3rd panel will examine the subject in detail, with experts considering
* The engineering calculations that quantify a design's projected energy performance
* Trade-offs between light, heat, and cooling loads
* What energy codes and standards presently apply and how recent high-glass designs have been able to meet them
* How new materials and designs can optimize the use of glass while meeting ratcheted down energy goals
As many of our older skyscrapers have their original glass curtain wall facades nearing end of life, these buildings will need to be "re-skinned." Thus these issues press not only on new construction but also on many existing buildings.
