CBE’s research team has developed new ways to “take the pulse” of buildings in operation: measuring the occupants’ responses to their indoor environments, and linking them to improved physical measurements of indoor environmental quality. We also study technologies that hold promise for making buildings more environmentally friendly, more productive to work in, and more economical to operate.
