City of South Bend, IN – Department of Public Works <br />RFQ Response: Guaranteed Energy Savings Contract <br /> Page | 9 <br />Administration and Laboratory Building <br />Veregy recommends installing solar on most of the <br />roofing area to maximize the amount of carbon <br />offset in the most economical method. The solar <br />produced electricity will also provide a positive cash <br />flow by offsetting purchases from the utility for the <br />energy consumed at Administration Building. <br /> <br />After the maximum amount of solar was placed on <br />the roof, the design was optimized. The projected <br />electric generation from this was compared to the <br />present consumption. The table above summarizes <br />our findings, and the layout for the array can be <br />found to the right. Further information about the <br />design can be found in the Appendix. <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br />Administration / Laboratory Building <br /> <br />HVAC Measures <br />Veregy engineers inspected all the facilities at the WWTP and found most of the HVAC systems <br />to be in good working order. It is our recommendation to replace a 7.5-ton ACCU, building <br />controls, and recommission existing systems in the headworks building. Replace building <br />controls and recommission existing systems in the administration building. Replace a window <br />air conditioning unit in the dewatering building with a central AC system and repair the window <br />where unit is removed. <br /> <br />LED Lighting <br />Our lighting engineer walked all the facility and found 392 light fixtures that we recommend be <br />upgraded to LED. This scope of work will realize a quick payback in savings and, coupled with <br />a rebate from the utility, will provide a great return on investment. <br /> <br />Administration / Laboratory Building <br />3113 Riverside Drive, South Bend, IN <br />Solar Array Size 60 kW AC <br />Annual Electric <br />Production <br />88 MWh <br />Existing Annual <br />Consumption <br />217 MWh <br />Portion Offset by Solar 28%
