SCIENCE BUILDING CONSULTING
The Science Behind Better Homes
Certified expertise in energy-efficient, healthy home design
Building science is a multidisciplinary approach to understanding how homes function and interact with their environment. By applying principles of physics, engineering, and building design, we evaluate how insulation, ventilation, moisture control, and material interactions affect energy efficiency, indoor air quality, and overall comfort. The goal is simple: homes that perform better, use less energy, and support healthier indoor living.
When these factors are overlooked, buildings can become inefficient, uncomfortable, and even unhealthy. We believe your home should be a place where your family can truly thrive. Thoughtful, science-based improvements have the power to transform how your home feels—and how you experience everyday life.

Fletcher Otwell and Stellar Air is one of the best service providers I have ever worked with … In a world where setting and managing expectations is critical, Fletcher set expectations for the process up front and provided informative updates during the whole process, while also being extremely responsive … Fletcher also showed an unparalleled respect for being in our home during the process. We are recommending Fletcher Otwell (Stellar Air) and Quilt to many more people.

Fletcher is fantastic. I've worked with several other heat pump installers in the past. None of them even came close to the skill, knowledge and expertise that Fletcher possesses. Fletcher was meticulous in all the phases of installation. It was comforting to know that this sophisticated heat pump system was being installed correctly. And it all paid off. The system which consists of 4 outdoor heat pumps and 4 indoor heads works perfectly.
