International Green Construction Code will include option for outcome-based approach

The 2015 International Green Construction Code (IgCC) will include the option to use an outcome-based approach when complying with local building energy codes, the first time the IgCC has allowed this method.

Previously, building energy codes relied on two main pathways to demonstrate compliance: performance (modeling energy consumption), and prescriptive measures (following code-defined values for individual building components). Both approaches fail to fully account for how buildings use power once they are completed, occupied, and maintained, according to the Institute for Market Transformation (IMT).

The new provision will help communities to ensure energy-efficient buildings are meeting performance expectations. The outcome-based approach requires the building owner to provide the building’s utility bills for a 12-month period within three years. This will ease pressure on code departments and align with the growing number of energy benchmarking regulations across the country, IMT says.

The decision to include an outcome-based pathway in the 2015 IgCC will directly influence future editions of the IgCC and other codes such as the Energy Conservation Code. This should smooth the process of including ASHRAE Standard 189.1 and the LEED green building program into the development of the IgCC, IMT says.

New York City has two very large buildings dedicated to answering the 911 calls of its five boroughs. With more than 11 million emergency calls annually, it makes perfect sense. The second of these buildings, the Public Safety Answering Center II (PSAC II) is located on a nine-acre parcel of land in the Bronx. It’s an imposing 450,000 square-foot structure—a 240-foot-wide by 240-foot-tall cube. The gleaming aluminum cube risesthe equivalent of 24 stories from behind a grassy berm, projecting the unlikely impression that it might actually be floating. Like most visually striking structures, the building has drawn as much scorn as it has admiration.
