Free app calculates maximum allowable heights and areas for buildings

A free app that calculates the maximum allowable heights and areas for buildings of various occupancy classifications and types of construction has been released.

The Heights & Areas Calculator, developed by the International Code Council, the American Wood Council, and WoodWorks, is based on provisions in the 2006 to 2015 editions of the International Building Code.

Users can input a given building geometry, site conditions (e.g., open frontage), type of construction, and occupancy.

The tool then shows allowable types of construction that are permitted. The “basic” version of the calculator limits building input to a single occupancy and equal floor areas for the entire building. An “advanced” option permits multiple occupancies and different floor areas.

“We often work with design teams that are exploring wood construction as a way to cost-effectively increase the density of their projects,” said Bill Parsons, vice president of operations for WoodWorks, in a news release. “The new heights and areas app lets building designers quickly determine if they’re maximizing value based on the objectives of the project, and to compare the options available with different construction types.”

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.
