Walden Pond Visitor Center
General Finances
Funding for the Walden Pond Visitor Center project came from the Commonwealth of Massachusetts, the majority of which came from DCR capital funding. Approximately $255,850 from two grant programs were obtained from the Massachusetts Department of Energy Resources (DOER), related to the zero net energy building and renewable energy components. Other components, including the 100 kW solar canopy, were funded separately. The costs below include non-building costs, including significant site work including the construction of a 100-foot ADA-accessible ramp, landscaping, parking lot reconfiguration, and improvements to a crosswalk across Route 126 to improve pedestrian circulation around the reservation.

Visitor Center - two grants were obtained from MA DOER. One grant, totaling $130,850, funded certain components to fulfill the net-zero design including R-60 roof insulation, R-40 wall insulation, 0.20 U-Value triple-paned windows, LED automated lighting systems, and low flow plumbing fixtures. The other grant totaling $125,000, funded renewable thermal components including a Mitsubishi 12-ton VRF heat pump system and a solar hot water system.
Solar PV array - two grants were obtained, totaling $59,720. One $52,920 grant for the solar PV array was obtained for DOER that covered the construction costs of the canopy, A second grant from the Massachusetts Department of Environmental Protection for $6,800 assisted with the cost of two dual-head Electric Vehicle (EV) charging stations.

A credit of $3,200 was applied to the Walden Visitor Center electric bill by Concord Municipal Light Plant.

Because the building purchases power from a local utility rather from a major utility company, the per-kWh price for excess power is diminished. Revenue generated through the sale of SRECs has been helpful for the economics of the project. If constructing a project in Massachusetts with a local utility, early discussions are recommended to determine anticipated excess sale pricing, rate categorization, ability to bank excess credits, etc…
