One of our goals when building this 7500 square foot branch for Greenfield Savings Bank, designed by architect Joseph Mattei, AIA, was to demonstrate that a large building can be built to the same energy saving standards as a small building. With a final Energy Star Leakage Area Calculation of 1.01 sq/in per 100 sq/ft (14,400 sq/in) of shell area, everybody was pleased with the results. Once we had the shell insulated, we heated the entire site during the interior finish in the winter with one wall hung Modine heater.
