Prof. Armstrong completed his BSc in Engineering Design and Economic Evaluation from the University of Colorado in 1975 and MSc, Mechanical Engineering, from Colorado State University in1980 where he was responsible for instrumentation and monitoring of the second of three NSF research houses at the Solar Energy Applications Laboratory. He continued to work at SEAL as research engineer in charge of the REconfigurable Passive Energy Analysis and Test (REPEAT) facility until 1985 when he founded Colorado Energy Associates. At CEA he led DOE and ASHRAE research projects on control of thermal transients and solar gains in buildings as well as numerous energy analysis projects for NREL, local architects, and private clients. He provided technical assistance to the Gansu Natural Energy Research Institute, PRC under a UNDP grant. He joined Pacific Northwest National Laboratory in 1990 to lead a number of Federal Energy Management projects (NPS-Ellis Island, five FORSCOM sites , WGNAS, Rome AFB, etc.). Armstrong directed instrumentation of 40 buildings in six Russian cities under the World Bank Enterprise Housing Divestiture Project 1995-98 and was recognized as one of the Lab’s top 30 inventors 2000-2003. He received his PhD from MIT, Building Technology program, in 2004. Armstrong is a Fellow of ASHRAE. He serves on several technical and standards committees and recently completed a term as chair of TC1.13, Optimization, from 2017-2019.
