Is anyone familiar with NYC development strategies? I ask because I’m curious as to the significance of these proposed code revisions:

• Exempt external building insulation from floor area requirements, allowing existing buildings to add insulation within their property lines;
• Eliminate penalties for high-performance envelopes in the way floor area is measured, by exempting a portion of thicker, better insulated walls from floor area calculations when buildings substantially exceed the New York City Energy Conservation Code;

Under what circumstances does these rules incent exterior foam insulation?
