Energy Task Force briefs Selectmen
Upgrades to town buildings are expected to save the town about $4,500 per year in annual energy costs. Dan Cook, Chair of the Carlisle Energy Task Force, gave the Selectmen on December 7 a description of three Carlisle buildings (Town Hall, the Police Station and Transfer Station/DPW) where electric energy efficiency projects have been completed.
The projects consisted of replacing existing fluorescent lighting with more efficient lamps and ballasts, upgrading exterior lighting to more efficient fixtures and installing motion sensors to turn off lights when no one is around.
After factoring in the utility installation rebates, projected annual cost savings are: Town Hall – $1,008 with a payback period of 5.2 years, Police Station – $1,516 with payback of 2.8 years, Transfer Station/DPW – $2,007 with payback of 2.6 years. The Task Force will be monitoring the energy use in these buildings to confirm the actual energy savings. Also, a new hot water boiler and hot water heater have been installed at the police station.
A current project is attempting to improve the efficiency of the heating and cooling systems in the Town Hall where there are problems with the insulation, duct work and controls. The Task Force is also arranging energy audits at the Carlisle School and the library with NGRID and NSTAR. If Carlisle qualifies as a Green Community under the Massachusetts Green Communities Program, the town would be eligible to receive funding to finance additional energy efficiency projects for town buildings.
Task Force member Helen Young developed the website www.carlisleenergytaskforce.org, which includes:
• Information about the Green Communities Program
• Energy audits that have been completed to date
• Energy use in town buildings
• A copy of the Carlisle Stretch Code and information about it
• Links for town residents to call NGRID and NSTAR to have their homes audited so they can take action to reduce energy costs and their environmental footprint. ∆
