Bringing Energy Full Circle


At Performance Systems Development, we are passionately committed to building performance by improving the energy efficiency of buildings.  Our training, software, services provide you with the tools, support, and knowledge needed to achieve peak building performance.  These efforts yield energy efficient, safe, healthy, and comfortable spaces in which to work and live.

Our clients span 47 states, and include energy efficiency programs, energy service providers and commercial building owners.  Energy efficiency programs in over 20 states rely on our program software to manage information, track jobs, and report results.  Our hallmark energy modeling software (TREAT) is used by thousands of energy auditors and engineers nationwide. TREAT serves the needs to many weatherization agencies and is still the only DOE-approved software for weatherization programs serving all building types from mobile homes to multi-family dwellings.  And a growing number of commercial building owners and managers rely on our benchmarking and energy tracking software and services to track commercial building performance and prioritize efficiency upgrades.
