Craig Wray has 30 years of experience as a consulting engineer and building scientist addressing energy, airflow, pollutant transport, and commissioning issues in both commercial and residential buildings. As a Mechanical Engineer at Berkeley Lab, his current efforts focus on air-handling system experiments, modeling these systems, developing related diagnostic methods, and assessing benefits and risks related to improvements.

Mr. Wray has Master of Science and Bachelor of Science degrees in mechanical engineering from the University of Manitoba, and is a registered professional engineer in Manitoba and British Columbia. At ASHRAE, he is currently Vice Chair of the Multidisciplinary Task Group “High Performance Air-Handling Systems for Buildings Except Low-Rise Residential Buildings”, and in the past has served as Chair of the Technical Activities Committee and Head of the “Load Calculations and Energy Requirements” Technical Section. He is also active on several Technical and Standards Project Committees. Mr. Wray was a recent Co-Chair for the American Council for an Energy-Efficient Economy’s Summer Study on Energy Efficiency in Buildings. He is a recipient of ASHRAE's Distinguished Service Award and DOE's Outstanding Mentor Award, as well as two Berkeley Lab Outstanding Performance Awards.

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