We are a Certified Building Commissioning Firm  (CBCF) of the Association of Energy Engineers (AEE) and proud corporate members of AEE, IDEA, ASHRAE, USGBC, AABC, and BCA.  We are “Systems Integrators” and can provide you with the latest advances in the emerging field of remote monitoring and control of building energy and automation systems.   Facility energy engineering is all we do.  We are not a design firm that also offers energy engineering.  Our “product” is our professional advice and service in optimizing HVAC, CHP and central plant systems.  Our recommendations are independent and unbiased.  We don’t have design solutions or products in mind when we start a project.  Because we only sell our professional judgment, we have taken extreme care in assembling our professional staff.  When you click on “About Us”, we think you will agree Bee is different and impressive.

Bush and NASA Astronaut Scott Parazynski, MD are among this year's prestigious guest speakers. 
  • July 2017: Bee® engineers are heading for Hong Kong to present seminar and CBCP workshop to assist its Environment Bureau's EMSD (Electrical and Mechanical Services Department) to promote Retro-Commissioning as a powerful tool for the "Energy Saving for All" program.  
  • March 2017: Bee® engineers are selected and invited to DC to DOE's Building Technology Office (BTO)'s program peer review.  
  • December 2016: Bee® engineers presented AEE's CBCP training course for certification in Toronto, Canada, November 28 - December 2, to building and ship commissioning professionals and peers from local Toronto, Ontario, and across Canada.  We have witnessed the new building Cx and existing building RCx's birth and growth in Canada from the first-row seats and are very pleased and proud to have contributed and demonstrated, and will continue to do so.
