As a BPI Building Analyst, your primary responsibilities include conducting comprehensive home energy audits, assessing building envelope performance, and identifying opportunities for energy efficiency improvements. You will use specialized diagnostic equipment to measure air leakage, evaluate insulation levels, and test HVAC systems for safety and performance. Regular interaction with homeowners or property managers is common, as you'll need to explain audit findings and recommend practical solutions. The role often involves working both independently and as part of a team with energy consultants, contractors, and utility program administrators. This hands-on, investigative work plays a key role in improving comfort, safety, and energy savings for building occupants.
