Mary Ann Piette is a Staff Scientist and Director of the Building Technology and Urban Systems Division at Lawrence Berkeley National Laboratory. She oversees LBNL’s building energy research activities with the US Department of Energy and many other R&D sponsors.  She is also the Director of the Demand Response Research Center that evaluates and develops new technology to improve the capability of demand responsive end-use loads. Mary Ann is lead PI on the automated demand response technology known as OpenADR which is in used in over 10 countries around the world. OpenADR is the most prominent open standard for communication between electricity providers and customers. It has been used over 5000 customers in homes, large buildings, and industrial facilities. Mary Ann conducts research related to demand-response load control, open standards, building energy use, sensors, controls, information systems, and fault diagnostics, simulation, and end-use analysis. She has authored over 170 papers on efficiency and demand response.  Mary Ann has worked at LBNL since 1983 and has an MS in Mechanical Engineering from UC Berkeley and a Licentiate in Building Services Engineering from the Chalmers University of Technology in Sweden. 

This publications database is an ongoing project, and not all Division publications are represented here yet.
