Originally built in 1910 as the stables for the Marshall-Wells Hardware Company, the Lovejoy Building is the home of Opsis Architects. The owner/architects purchased and renovated the historic building to house their growing business and to provide ground-floor office lease space and second-floor offices for their firm.

Opsis wanted to use the building to experience and demonstrate the technologies and practices it promotes with clients. Creating an open, comfortable and resource-efficient office space was a priority; incorporating upgraded efficiency features was considered an integral part of the normal project budget.

Environmental Aspects

Opsis wanted to incorporate as many energy-efficient measures into the building as possible, and it was able to include almost everything it considered. Lighting controls, operable windows and night flush were some of the measures for which the owners were willing to pay more. Radiant concrete walls were studied but were determined to be cost-ineffective. Some significant features used are:

• High thermal mass envelope
• In floor radiant heating/cooling
• Night flush
• Automated sunshades
• High performance glazing
• Daylighting with window, skylights and dimmable ballasts
• CO2 regulated demand control ventilation
