With New York City’s 80x50 initiative to reduce greenhouse gas (GHG) emissions 80 percent by 2050, the stakes are high for the city to adopt progressively more stringent energy codes.

Insulation is a critical component to specify when designing a functional, cost-effective, and energy-efficient building. One method to insulate a building is by installing 50 to 152 mm (2 to 6 in.) of rigid foam insulation on the exterior side of the wall framing.

Buildings are a combination of design and construction. On paper, it may all seem to flow and make sense, but a small change in the former can have major impacts on the latter. Alterations that happen during the construction phase can end up causing significant design problems.

With glazed façades dominating urban landscapes, the strides made to improve the energy efficiency of glass are well-documented and generally well-understood. However, the framing members of wall and window systems have also been re-engineered.

Insulation manufacturers have devised numerous ways to improve the thermal performance of their products. Adding carbon or alumina particles to expanded polystyrene (EPS) increases infrared reflectance, and hence boosts R-value. For buildings that need heat stopped during the day and released at night, there are phase-change materials.

The fluid-applied air barrier (FAAB) concept was originally a Canadian-developed technology from more than 40 years ago. Back in the early 1970s, the genesis was an adhesive combining air- and vapor-retarding characteristics—eventually, this material would find its way into building codes.
