How do I become an energy auditor?

There are many paths that a professional can take to become a certified energy auditor or building analyst. The best way to start is to sign up for a building performance class with a reputable organization such as Stonehenge Associates. As a Certified BPI Test Center, we are qualified to administer certification tests for the full range of BPI certifications.

I already have insulation. Why do I need an energy audit?

Unfortunately, the insulation in many North American homes and buildings does not perform to its rated R-value in the real world, due to a number of factors including settling over time, improper installation, and other factors. We can analyze your building's insulation and determine whether it's actually working, or whether you could benefit from an upgrade. As an independent analyst, we do not profit from our recommendations.

How do I pay for my energy retrofit?

The upfront cost is often enough to dissuade homeowners from investing in home energy upgrades. However, this investment is one of the best that a homeowner can make, leading to energy savings throughout the year. Fortunately, New York State offers generous incentives for home performance upgrades. In other areas such as Vermont, Connecticut and New Jersey, other programs are available to offset some of the upfront costs. We can help you figure this all out.

How do I get started?

What is an Energy Audit?

An energy audit is a comprehensive investigation of your home or building from an energy efficiency standpoint. We analyze the building envelope, levels of insulation, air-tightness, HVAC equipment, and other areas of your home that may contribute to energy waste. In doing so, we also evaluate your home for health issues such as poor indoor air quality.

What are the top energy savings measures for buildings?

The best energy savings measure for a building depends on the details of that building. Typically, however, measures such as attic insulation, air sealing, wall insulation, crawlspace encapsulation and duct sealing are the most cost-effective building upgrades.
