CleanEdison's Building Performance Institute (BPI) Building Analyst Essentials covers the basic principles of building science, including assessing energy efficiency in a home while also monitoring conditions that have a direct impact on human health and safety. This manual works best as an accompaniment to the CleanEdison training program aimed towards those interested in becoming BPI Building Analysts, but will also be useful to those that are interested in learning about residential energy efficiency more generally. BPI Standards emphasize the 'house-as-a-system' approach to inspecting a home, meaning that all systems are interconnected, from the HVAC equipment, to the envelope, the foundation, walls, roof, doors and windows. You will learn how to use diagnostic equipment such as the blower door and the combustion analyzer to ensure systems are functioning together correctly to maximize home performance, comfort, energy efficiency, safety and durability. CleanEdison offers online and live, in-person trainings in a variety of green building fields all around the United States.
