MEP Assessment for Greener Buildings

Solid information to guide energy-saving, money-saving decisions.

Building Performance Analysis

When Grumman|Butkus was launched in 1973, energy studies were the first service we offered.

Today, we still provide diverse facility analysis services to help owners make the most of their buildings: reducing energy use, cutting costs, and dialing down greenhouse gas emissions.
