G.Z. Brown, director of Energy Studies and Buildings Laboratory, just returned from the National Energy Efficiency Technology Roadmapping Summit. Researchers in building energy use were invited to update and refine a portfolio of residential and commercial technology roadmaps. Their efforts helped to establish a “research agenda to guide technology investment strategies in building design and envelopes, lighting, HVAC, energy management systems, and other areas.” Brown described the Sloan-funded BioBE project and the potential for microorganisms to enhance the energy performance of buildings.
