Putnam Green

Putnam Green, a 100% affordable development comprised of 40 units in two buildings, utilizes a number of Green Features that contribute to its certification as a LEED Platinum building. Below are a sample of some of these efficient and innovative features. A more extensive list of our greening efforts can be viewed at the bottom of this page.



The building envelope is tightly sealed and insulated to minimize heat loss. 625 Putnam Ave. will use 32% less energy than required by the national energy code.  This means lower heating costs and quieter, more comfortable homes.

Superinsulated Panels (SIPS) were used to build 254 Sydney Street to keep it air tight.  The walls have an R-30 rating.

Energy Recovery Ventilators exchange the energy contained in normally exhausted building air and use it to precondition the incoming outdoor air for ventilation.    During the warmer seasons, the system pre-cools and dehumidifies while humidifying and pre-heating in the cooler seasons.

A 10kW solar electric systemwith 50 photovoltaic panels that provide energy to offset the lighting needs for the hallways, stairwells, and elevator.  

A solar domestic hot water system will preheat water that is used in the apartments.  This will save more than 1,000 therms of natural gas per year.

Landscaping features drought-tolerant and low-maintenance plants including: ginko, dogwood, blue holly, magnolia, hydrangea, feather reed grass, coneflower, daylily, juniper, and low bush blueberry. 

BTU Meters have been installed to track the energy consumption of each of the two buildings.  This will allow the owners to evaluate and track the energy consumption of each building off a central boiler system.

A full list of the green features that make this development LEED for Platinum can be found here.
