Case Study | Cambridge Multi-Unit

exteriorAedi Construction is focused on building and renovating eco-friendly homes and office spaces that are resource efficient and responsive to the environment. We were awarded the first LEED-H certification for a multi-unit building in the country and were awarded the first LEED-H certified home in Massachusetts. The Cambridge City Council and Mayor’s Office recognized Aedi’s leadership via a unanimous resolution to encourage further ‘green’ development. Since a considerable amount of US housing is multi-unit buildings, we believe it is significant to have established a design template to encourage others to convert existing multi-unit buildings into LEED certified living environments.


ExteriorAedi selected 53 Standish Street for its proximity to parks, public transportation, shopping and schools within Huron Village in West Cambridge, MA. Aedi transformed a traditional three unit shingled building into a more contemporary exterior by using pre-painted Hardiplank® clapboard siding and trim with low-e black windows. The design intent was to subtly convey modern lines while complementing other buildings in the neighborhood. Native plantings and a permeable parking area helped to minimize water use, improve drainage and eliminate harmful effects of black top paving while still offering a stylish, modern design.


living roomWhile conventional multi-units in the area have traditional interior room partitions, we chose to create an open floor plan to maximize the benefits of natural sunlight and to create an ‘eye stretch’ feeling to the outdoors. The main interior wall design is angled giving a ‘foreshortened perspective’ (making the unit feel larger) while maximizing space for bedrooms, closets and the HVAC system. This approach eliminates hallways -therefore no wasted space – and maximizes circulation. The second en-suite bathroom functioned as a common bathroom and bedroom bathroom (2 entries), reducing the need for a hallway lavatory. The enclosed rear porch serves as a home office space to conserve transportation costs and improve quality of life.


kitchenEnergy Star® awarded us with a 93.3 HERS rating – an exceptional score for a development property. Elements such as cellulose insulation in the exterior walls, interior walls and ceilings; Low-E windows; Rinnai® on-demand hot water heaters; Energy Star® lighting fixtures and appliances such as Bosch®, LG®; Toto® dual-flush toilets; Kohler® low flow water fixtures; Carrier® 16 SEER HVAC system and wiring for solar panels all contributed to our very high Energy Star® rating.


bathTo maximize the health of the indoor living environment we installed programmable, automatic venting systems and overhead venting above the stoves. In addition, we used bamboo flooring; recycled glass tiles; recycled quartz countertops; non-formaldehyde filled doors; 99% recycled wall board with 100% recycled paper; FSC certified wood trim; recycled newspaper for insulation; recycled carpet and walk-off mats; non and low-VOC caulking, paints and sealants and recycled composite decking.

By design, unit owners enjoy what we call “sustainable luxury™” - energy savings, healthier living and designated outdoor space without compromising on the modern elements and amenities found in conventional buildings.
