Track record
Fifteen years of energy engineering: utility program assessments, implementation projects, a national lab research team and the design of Denver's building electrification program.
- 689electrification feasibility reports tracked in Denver's building electrification program, which Miles designed and launched
- 211Ask E research answers for 48 utilities and efficiency organizations across North America (E Source)
- 16.8 millionkWh of annual electric savings identified in the reports reviewed
- 1,072,000therms of annual gas and steam savings identified
- 17,803metric tons of CO2 avoided per year if implemented (EPA factors)
- 158buildings assessed or improved in five states, across higher education, K-12, recreation, municipal, public safety, healthcare, industrial, hospitality and multifamily
Savings are annual figures identified for recommended measures in utility program assessments, ASHRAE audits, retro-commissioning studies and investment grade audit work, including desktop and AI-assisted retro-commissioning studies prepared at a national ESCO. They are estimates from reports, not verified results. Carbon uses EPA factors of 0.703 t CO2 per MWh, 0.0053 t per therm of natural gas and 0.00664 t per therm of district steam.
