Macallen Building Condominiums

Project Information

The Macallen Building, a 140-unit condominium building in South Boston, was designed to incorporate green design as a way of marketing a green lifestyle while at the same time increasing revenue from the project. Located in a primarily industrial area among highways, train and bus routes, and an international airport, the site presented challenges for the project team tackling air and noise pollution, addressing the urban heat-island effect, and creating local green space.

The green building features include innovative technologies that will save over 600,000 gallons of water annually while consuming 30% less electricity than a conventional building. This dedication to sustainable initiatives produces many benefits for everyone involved in the project: developer, architects, engineers, and residents alike.

Environmental Aspects

This LEED Gold project has a sloped green roof that controls stormwater drainage, filters pollutants and carbon dioxide out of the air, reduces heating and cooling loads, reduces the project's contribution to the urban heat-island effect, and provides an ecosystem for wildlife. A 20,000-ft2 outdoor terrace incorporated into the building provides similar benefits as the green roof. In addition, a covered garage was integrated into the building to reduce overall square footage and contribution to the urban heat-island effect and stormwater runoff.

The building is well insulated and features several energy-saving technologies, including heat-recovery ventilation and water-source heat pumps. No potable water is used for irrigation on the site. Instead, rainwater and air-conditioner condensate are collected and stored for use. In addition, the project was awarded a LEED innovation point for the use of a system that treats cooling tower blowdown water without the use of chemicals for use in irrigation.
