We care deeply about making our built environment more energy efficient. We realized a few years ago that contractors and building energy professionals were spending way too much time collecting data and still getting left in the dark with poor and inconsistent modeling results. So we decided to take a whole new approach to energy assessment, one that completely leverages available information, minimizes the impact of unknowns and guesses, and provides real-time feedback to the user from the best physics-based models. The result is remarkable. We are able to streamline the assessment process, save our users significant time and money, help people become better auditors, and help home and building owners save A LOT of energy! In addition to our residential building performance software, OptiMiser now provides do-it-yourself customer-facing audit websites, a project management system, a commercial building portfolio utility analysis platform, and custom solutions of all sizes for lots of people in the building performance industry.
