Project Title: Levedo Residential Development
Location: 241 Talbot Avenue, Dorchester MA
Client: Domenech Hicks & Krockmalnic Architects
Description: This project involves mechanical, electrical and fire protection design for a four story, 24 unit residential development to be constructed at 241 Talbot Ave in Dorchester. The design includes “green” technologies, such as heat recovery, enhanced ventilation, photovoltaic solar energy and high efficiency boilers. The building team has applied for LEED Homes Certification and the Energy Star Homes Program.

Project Title: Visiting Nurses Association
Location: 405 Alewife Brook Parkway, Somerville, MA
Client: Chia Ming Sze Architects
Description: The VNA project was the first phase of development of a 194 unit complex of handicapped accessible apartments for senior living.

The design incorporated several “green” technologies, such as solar power, rain water recycling, cogeneration of electricity and Advanced Building Design (A.B. Design), which is promoted by the utility providers.

The second phase of this project is the redevelopment of the City of Somerville’s Capen Court Senior Housing, which will be the first affordable Continuing Care Community for low and moderate income residents in the country.

Project Title: Viet-Aid
Location: 1460 Dorchester Avenue, Dorchester MA
Client: Chia Ming Sze Architects
Description: This mixed use transit oriented project created 43 affordable studio and one bedroom units occupying three floors above 5 commercial spaces.

The design included solar panels, balanced ventilation, heat recovery and highly efficient boilers. The project was one of five recipients of the national Energy Star Affordable Housing awards in 2009.

Project Title: Good Shepherd Day Care
Location: Milford, CT
Client: The Office of Michael Rosenfeld, Inc., Architects
Description: The HVAC systems serving the building consist of a high efficiency, variable speed gas furnace for heating with an integrated refrigerant coil for cooling.

In addition to the furnaces for heating, the classrooms are being heated with hot water radiant heat. The hot water is generated by a small gas fired boiler which is 95% efficient, as are the furnaces.

The ventilation systems utilize an energy recovery unit which tempers the outside air being introduced into the building with the exhaust air being taken from the building. By implementing this system, the overall system capacity required for cooling and heating of the building was reduced. Additionally, the outside air is continuously being adjusted to meet the needs of the spaces.
