Cambridge, MA


Tocco Corporation

This project consisted of a renovation to a 9,395 sq ft historic building originally constructed in 1891 to meet Passive House standards. 5 Sacramento St. is owned by Harvard University, and is currently being used for student housing. The building consists of 5 units (3 of which are lofts) each containing 4 bedrooms, 2 bathrooms, a full kitchen, and living area.

In order to comply with passive house standards, ESE designed all new utilities and electrical systems throughout the interior as well as new site electrical work, communication pathways, and site lighting. Some of the interior electrical systems ESE engineered included LED lighting and associated branch wiring, emergency and exit egress lighting, automatic lighting control, mechanical systems power, electrical load calculations, new electrical service, receptacles, power distribution, voice and data plaster ring/stub and string as well as conduit sleeves. In addition, our team designed a new addressable speaker/strobe fire alarm system with voice evacuation, which was provided throughout the building.

This building was designed to comply with 9th Edition of the Massachusetts Building Code and NEC/MEC 2020.
