Let's be real here. I'm "certified." Lots of people are certified. So what? Who certifies them?
You're probably here because you're shopping for someone. You need an energy audit, or some insulation, or an air conditioner, or your electricity bill is high, or you have questions, or you're sneezing a lot and don't know why, and you don't know who to call.
So do this. Go to BPI's website and choose "Hawaii." Last time I checked, there were two BPI-certified people in Hawaii. Only one of them on the Big Island. Bonus points if you guess who that is.
Do your contractor have what you need?
Here's a dirty secret: if you call a company, any company, you might get the new hire. Or the salesman. You deserve better.

The skinny: The Building Performance Institute is the nation's leading building science accreditation organization. The "house as a system" philosophy looks at a building's various components (building envelope, attic, basement, combustion equipment, ventilation sources) and the relationship between them to make your house more well-behaved. This approach leads to greater energy efficiency and to buildings that simply work better. A home that has been analyzed and upgraded from a whole-house standpoint is healthier, more comfortable, and more energy efficient. For information about BPI's standards, check it out: Technical Standards for Building Analysts (PDF).
