District Energy Initiatives 1/23/2012

National Grid – New England Gas Whole Building Assessment (WBA) 1.)Assess energy performance Building envelope Electrical systems HVAC systems Lighting systems & equipment Operation & Maintenance procedures 2.) Identify opportunities for improvement Low & No Cost Opportunities (1-3 years) Capital replacement recommendations (5-10 years) 3.) Action Plans recommended Incentive programs

Low Cost – 2.2 years or less payback period  Education & awareness *  Computer power management *  Vending machine controls  Air sealing/weatherization (doors & windows)  Freezers – National Resource Management (compressors, fans, evaporation controls, temperature controls, defrost controls, walk-in-curtains) *  Demand controller HVAC – Gymnasium *  Compressed air system (pneumatic) assessment  Destratification fans – Gymnasium & Auditorium  Operation & Maintenance practices * * In-process or already completed

Low Cost – 1.4 years or less payback period  Education & awareness *  Computer power management *  Vending machine controls  Freezers – National Resource Management (compressors, fans, evaporation controls, temperature controls, defrost controls, walk-in-curtains) *  Air sealing (classroom exhaust)  Programmable thermostats  Timer on exhaust fans  Insulate hot water pipes (Boiler Room)  Operation & Maintenance practices *   * In-process or already completed

 Review of Energy Efficiency Measures (WBA) Joseph Case Junior High School & Joseph Case High School  Assess other buildings in district for EEM’s  Identify District’s priorities, goals & resources  Determine schedule for implementation of EEM’s  Implement no/low cost measures that do not require further study using:  National Grid Direct Install Program  Internal facilities personnel  Private vendors/procurement  Determine objectives and level of interest to proceed with more detailed research and engineering  Some recommendations may require further investigation as noted in report  Contact National Grid & New England Gas to begin detail study for specific measures  Implement selected measures after their scope of work, costs and energy savings have been evaluated and determined.
