Dan Coley

Project Manager

Our Board

Doug Mahone

Board of Directors

Doug Mahone joined the Taper Board after retiring from a forty year career in energy efficiency. After completing his architecture degree at MIT, he was appointed as an Assistant Professor to research and teach solar energy and building science subjects. He then left MIT to join a pioneering solar energy firm in New Hampshire, which lasted until Reagan discontinued their research funding. That precipitated a move to California. Once here, Doug worked for several Bay Area energy firms, getting involved in energy simulations, daylighting design, and energy codes. In 1994, he and his wife, Lisa Heschong, started the Heschong Mahone Group in the Sacramento area. HMG grew to 40 employees and three offices, becoming known for their work in energy codes, program evaluation and implementation, and building science research. Along the way, Doug helped form the New Buildings Institute, the Cool Roofs Rating Council, and the California Energy Efficiency Industry Council. In 2013, HMG was sold to TRC Energy Services, so Doug and Lisa retired and moved to Santa Cruz. In addition to joining the Taper Board, Doug serves on the California Technical Forum. When not working, Doug is a bluewater sailor, horseman, hiker, and granddad. He has undergraduate and Master’s Degrees in architecture from MIT.

Before joining UCSC she worked for Santa Cruz County Environmental Health Service as the Program Manager for the Hazardous Materials and Solid Waste programs.
