The document analyzes energy efficiency opportunities in the Herberger administration building. It estimates that the building consumes 12-14% of the total metered energy based on its size and functions. Lighting makes up almost half of energy usage. Converting remaining lights to more efficient T8 bulbs and adjusting lighting schedules could save over 2.5% on the annual energy bill. Appliances like computers and copiers already meet standards while optimization of vending machines could save over $600 annually. Replacing aging chillers qualifies for large tax credits and would improve efficiency over twice as the current system. Commissioning the HVAC system could ensure proper functioning and calibration for improved performance.

3. Notes on Calculations Lighting and Office Appliances were calculated through “bottom-up” physical inventory of building HVAC was calculated from a “top-down” approach, as follows:

4. Average Yearly Cost Creation of estimate range based on building type Since the Herbergerbuilding houses more lighting, office equipment, and a greater air volume due to large foyers and auditorium, it is estimated that the building consumes anywhere from 12 to 14% of total metered area.

8. The Average T12 bulb lasts only 12,000 hours, effectively doubling the purchase/replacement of lightCurrent Replacement Costs

9. Appliance Analysis and Recommendations Great News! Computer consoles and monitors exceed EnergyStar guidelines and represent low electrical usage, regardless of sleep mode or power off mode Xerox machines also offer powerful energy savings, though these features may not be optimized Optimization of power settings will enable maximum energy savings of up to 7,900 kWh, a reduction of $645 annually Vending machines represent huge drains of electricity, though this can be mitigated in two ways Requesting to vendor that machines be delamped costs nothing, and will instantly save $286 annually Vend Misers can also be installed, at a cost of $358, and savings of $143 annually, creating a payback of 2.5 years

10. HVAC Analysis and Recommendations The two 200 ton York chillers are nearing the end of their lifespan, and replacement qualifies for Federal tax credits of $.60-1.20 per square foot of the buildings they service (Energy Policy Act of 2005). At 51,608 sq ft., the Herberger building would qualify for $30,965 to $61,930 in rebates to replace chillers Projects servicing areas less than 100,000 sq ft. with electricity rates greater than .07 per kWh and usage hours above 5,000 per year are ideal candidates Eliminates the use of R11 and R12 refrigerants, which contain CFCs that harm the ozone (banned from production in 1996, though quantities still available)
