MISSION

Our mission is to create value in energy-efficient construction
with practical, cost-effective solutions driven by building science.

To keep up with greater expectations of performance and quality, municipalities all over the country have adopted more and more building, energy, and fire code regulations to produce better performing homes and work spaces. Yet this puts a greater burden on developers to create a better product without increasing costs. We understand that problem, and work with you to balance the need to build better at a reduced cost. Our track record in Michigan’s residential building industry speaks for itself. Almost all of our clients come to us from referrals. That’s because not only do we offer the analysis and code compliance you need, we advocate for you where it matters – out in the field on your job site. Let us navigate you through the maze of code requirements by helping you understand the options, decide the best route, and deliver a code compliant new build.

"I first met Don Nelson, President of D.R. Nelson & Associates, in 1982. At that time, we asked him to help us do a better job of insulating our houses. What impressed me was he solved our problem by thinking outside the box, and he has been that way with every problem we ever asked him to solve regarding energy efficiency. I think he is a terrific individual and very talented. He's the best!"
