We are a Certified Building Commissioning Firm  (CBCF) of the Association of Energy Engineers (AEE) and proud corporate member of AEE, IDEA, ASHRAE, USGBC, AABC's ACG, 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.
