921 Columbia Street

921 Columbia Street, located in downtown Hudson, is a low-income, five-unit rental property constructed around 1920.
Through the State, the owners received an Energy Reduction Plan, which recommended cost-effective energy improvements.
The $58,000 project consisted of installing attic and wall insulation, double-glazed windows, water heater insulation, and compact fluorescent lamps. Inefficient refrigerators were upgraded and the central boiler was replaced with high efficiency boilers in each apartment with improved temperature controls. The Energy Reduction Plan projected an 11 percent reduction in electricity consumption and 51 percent reduction in natural gas consumption, for a total energy use reduction of 20 percent. Financing for the work came from a variety of sources including State incentives, low-interest loans and building reserves.
As a result of the improvements, the property realized a reduction of 27 percent in overall energy usage, better than originally projected. Since each tenant pays for their own utilities, this had a direct benefit for them. Tenants saw a reduction in their consumption and subsequent costs, in addition to the common areas.
