About Building Energy Diagnostics

At Building Energy Diagnostics, we believe every homeowner deserves a comfortable, healthy, and energy-efficient home. Our mission is to help homeowners understand how their home performs and identify opportunities to improve comfort, reduce energy costs, and increase overall efficiency.

Building science is the study of how a home’s systems work together—including insulation, air sealing, ventilation, moisture management, and heating and cooling systems. When one component underperforms, it can impact comfort, indoor air quality, durability, and energy consumption throughout the entire home.

Using building science principles and professional diagnostic methods, we evaluate how your home operates as a complete system. Through a comprehensive energy audit, we identify areas where energy is being lost, uncover hidden performance issues, and provide practical recommendations tailored to your home.

Whether you’re experiencing high utility bills, uncomfortable rooms, drafts, or simply want to improve your home’s efficiency, Building Energy Diagnostics provides the information you need to make informed decisions.

Building Energy Diagnostics measures building science in action—helping homeowners create more comfortable, healthier, and more energy-efficient homes throughout the Hudson Valley.
