Energy Service & Energy Audit Providers

Making your building more energy efficient involves doing things differently from the old standard. It may mean carefully evaluating energy use and building systems to ensure that operations are as efficient as possible, or tracking down local sustainable building products to make a lasting change to your space that reduces cost in the long term.

Identifying these types of specialized service providers can be tricky. As an advocate for healthy and high performing spaces, Green Building Alliance has compiled the following list of specialized service providers and nonprofit organizations that may be of assistance during your building project.
