The Ins and Outs of Revolving Doors

Figure 11

The built environment is an energy-guzzler. The U.S. Green Building Council (USGBC) states in this country alone, buildings account for 41 percent of energy use, 73 percent of electricity consumption and 38 percent of all CO2 emissions, and 13.6 percent potable water consumption. Globally, buildings use 40 percent of raw materials, or about 3 billion tons annually.1 Fortunately, the type of doors we select can have a big impact on a building’s energy profile.

The ‘investment’ made in them is as much about the firm’s design reputation, as it is about actual project budget.

Fire-rated curtain walls can prevent a fire from traveling to or from neighboring buildings without restricting visibility. Unlike gypsum, masonry, and other opaque fire-rated materials, this multi-functionality can bring fire and life safety goals in line with the aesthetic design intent where building codes deem the threat of fire is significant from adjacent construction.

Glazed curtain walls are best known for their ability to visually integrate two otherwise separate spaces. Less talked about—though, perhaps more important—are curtain walls with the capability to retain visibility and access to daylight while standing guard against fire.
