Our mission is to bridge the gap between energy analysis and implementation of energy efficiency measures.
When we take advantage of cost effective energy efficiency opportunities, we benefit individuals, businesses,
our nation and the environment.
Marcia Karr, P.E.
Marcia Karr P.E. is a mechanical engineer with over 30 years of experience in commercial building design,
construction, and maintenance and as a building codes plans examiner. She is a registered Professional
Engineer in Washington and Oregon and is a licensed Commercial Buildings Energy Code (NREC) Plans Examiner.
Marcia's range of experience lends perspective in designing calculation tools that meet the needs of HVAC contractors.
She has worked as a commercial sector plan and spec engineer, as a construction project manager and later as a trade
supervisor with a crew of 40 people from all the trades maintaining and operating buildings. She inspected job site
conditions, bid the jobs, designed the systems, obtained permits and supported her construction team to close out.
As the sole mechanical and energy plans examiner for the City of Portland, she saw every engineer's work in her
jurisdiction and supported the construction sector in doing good designs for their customers. Marcia often provided
these contractors with calculations to show energy savings for upgrades to their current direction.
In these years of experience, Marcia recognized the need for a software tool intended for contractors and building owners for
performing site-specific energy analyses of commercial buildings without the expense of building energy modeling.
Carolyn Roos, Ph.D.
Carolyn Roos is a mechanical engineer with over 25 years of experience in industrial and building systems energy efficiency,
