Increase Utilization & Maximize Savings

Energy efficiency programs are complex. How do you design and launch sustainable programs, encourage participation, comply with state and federal mandates, and receive verifiable energy savings?

To achieve peak performance of buildings, we translate building science into actionable information for energy efficiency program success. Our combination of technical engineering, and industry innovation enables PSD to see the big picture, apply best practices, and achieve unmatched results.

Collaboration is critical when it comes to the creation and delivery of cost-effective energy efficiency programs. Our team will engage and interact from day one to the final delivery. We listen to your needs and tailor our services to meet your program objectives.

Take Your Energy Savings to the Next Level


Easily at the top of our list are the programs run by PSD. Their commitment to full support of the program stakeholders through their intuitive Compass interface, live support, solicitation of constant feedback, quality training, and education make them a professional pleasure to work with.

HERS Rater

We have worked with PSD in the FirstEnergy New Homes program in Pennsylvania for the past couple of years. It is so refreshing to work with an organization that is easy to work with, supportive and quick to respond to any questions we have. PSD’s process of registering and applying for rebates is such an easy process. Thank you for making this so user friendly!

Energy Contractor

I love to work with PSD on above code and energy efficiency programs.  Their software is easy to understand and convenient to use.  There technical help is both knowledgeable and timely, I just send them an email and I usually hear back within an hour.  They make it easy for me to help my customers maximize their participation in the programs.

HERS Rater

I just wanted to thank you for the feedback, and for the quality of the QA report. Because of the many rebate programs in which we operate, we get a lot of QA done by the implementers of utility funded programs. This is by far the most professional QA report I have received from an incentive program.
