The document discusses several building projects where Petersen Engineering played a key role in integrating energy efficiency and renewable energy solutions. It describes instances where they helped teams commit to high performance building envelopes, simplify mechanical systems, optimize energy models, include energy efficiency in early design phases, address heating issues through the building envelope, and sign on to district heating systems with no fossil fuel backup. The case studies covered a variety of building types across New England and highlighted total energy usage goals ranging from 40 to 94 kBtu/sqft/year.
