Increasingly over the last several years, members of the building industry have expressed the need for both broader and more targeted benchmark data on high-performance buildings. The Commercial Building Energy Consumption Survey (CBECS) has long served as the major source of information on the energy use of the nation’s existing building stock. Its suspension last spring posed obvious challenges for data users in the building industry who gathered at a July hearing to discuss solutions. Last week, the National Institute of Building Sciences’ (NIBS) High-Performance Building Data Collection Initiative released a report, Data Needs for Achieving High-Performance Buildings, which incorporates the testimony of key industry players. The report, funded in part by NBI, is an excellent summation of where things stand and succinctly outlines data needs, sources and roles. It should also remind us of just how far we still have to go before a comprehensive and reliable source of widespread energy performance data is in place.Read NBI’s testimony from the July hearing.
