We are a proud active member of AEE, IDEA, ASHRAE, USGBC, AABC's ACG, NEBB, and BCA, a Certified Building Commissioning Firm (CBCF) by AEE, and a certified TAB firm by NEBB.  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.  With in-house more-than-handful Engineering Ph.D.s, Doctor of Engineering, P.E.s, and practical certifications such as CEA, CEM®, CMVP®, CWEP®, REP, CBCP®, CxA, LEED AP, and NEBB Certified Professional on TAB, our “product” is our professional advice and service in optimizing buildings and campuses, and their MEP and energy systems, including HVAC, BAS/PAS, central utility plant, CHP, TES, PV, EV, district heating and cooling systems, micro-grid, etc., for conservation, operability, reliability, efficiency, sustainability and resiliency.  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.
