BPI Certified Building Analyst: As a certified BPI (Building Performance Institute) Building Analyst, I have had training in BPI's rigorous house-as-a-system approach and kept conscientiously up-to-date on certification (BPI requires Building Analysts to be re-certified every three years). As a BPI Building Analyst I am certified to conduct blower-door tests, combustion appliance inspection and repair, air quality testing including carbon monoxide detection, duct testing and airflow testing in addition to my other contracting services. For more information about BPI's standards, take a look at their Technical Standards for Building Analysts (PDF).
BPI Certified Envelope Professional: Additional BPI training in building science allows me to go beyond a traditional energy audit to perform comprehensive, whole-home assessments, identify problems at the root cause and prescribe and prioritize solutions.
