Is it Conservation… • Conservation, By Webster a careful preservation and protection of something ; especially : planned management of a natural resource to prevent exploitation, destruction, or neglect 2: the preservation of a physical quantity during transformations or reactions …or Efficiency… • Efficiency, by Webster's effective operation as measured by a comparison of production with cost (as in energy, time, and money) (2): the ratio of the useful energy delivered by a dynamic system to the energy supplied to it …or Sustainability? • Sustainability, by Webster's of, relating to, or being a method of harvesting or using a resource so that the resource is not depleted or permanently damaged <sustainable techniques> <sustainable agriculture> b: of or relating to a lifestyle involving the use of sustainable methods Actually, It’s Easy to be all of these things… Existing Facilities Whether it is residential, commercial or industrial, Success is in 5 areas… – Space Conditioning – Lighting – Envelope – Ancillary Appliances – Process LES’ Sustainable Energy Program Goals 1. Financial savings to the consumer; 2. Mitigation of year-to-year system load growth; and 3. Concerted effort to reduce peak load impact. Year 1- Potential reduction of 6.4 MW in demand and 13,246 MWh in energy. Current Program Overview Continue to promote services currently built into service delivery & annual budgets, including: On Going Services – Walk-thru Audits – Compressed Air System Audits – Residence and Facility Thermography – Energy Star Homes – Energy Ideas on City Access Channel 5 – Energy Depot for Home & Business – Energy Efficient Mortgages – Energy Savings Tips New Program Offerings NEW Cash Incentive Offerings: 1. Whole House Tune Up Program 2. Low Income Weatherization Program 3. LES High Efficiency Heat Pump Program 4. Commercial HVAC Maintenance 5. Commercial Lighting Retrofit Program 6.
