As a LEED Proven Provider® our methods for documenting and earning LEED credits have been perfected over time and are trusted by the USGBC. We are truly experts as our team has collectively worked on over 400 LEED projects and 50 Million SF of commissioning, retro-commissioning, energy auditing, and energy modeling projects. What this means for you is that you will not miss any credits due to improper documentation or inexperience, and most importantly we can help you with every aspect of your LEED project. Most companies do not offer both LEED consulting and the engineering services required for some of the prerequisites and credits each project must earn, but we do.
