King Street <br />Hillsborough, NC 27278 <br />Ms, .Jones: <br />I look forward to the opportunity to work with Orange County on such a challenging and <br />exciting project. The sustainable goals put forth by your commissioners fbr the old Cedar <br />C,rovc School are wondertuh 1 would be very proud to be a part of making them come <br />true, 1 thank you for the opportunity. <br />The following presents a proposed list of optional strategies which I-Iarshad Padia (with <br />Padia Cmrsulting) and I feel are opportunities which should be analyzed. Depending <br />upon your budget for this initial work, you could decide upon the level of effort desired. <br />In our very tentative review, we have also tried to place these option in order, in terms of <br />relative potential benefit (both energy dollar savings and environmental impact). We <br />have also identified a fee associated with each item that would allow us to analyze the <br />particular item in relationship to the overall project. <br />To complete the following work, we will, from an energy perspective. require that the <br />current building be inputted into a total building energy simulation program. l o <br />accomplish this analysis, we use the best program available -DOG 11. To additionally <br />simulate any of the daylighting options, we use a program called DAYL.ITG which allows <br />us to simulate the daylighting contribution at numerous points within each individual <br />room, al! day long, 365 days a year. To determine the actual projected lighting and <br />cooling savings, this DAYLITE program output is, in turn, input into DOE 11, which <br />accounts for the savings occurring from the particular daylighting option in relationship <br />to the other building dynamics. 7o calculate the rainwater savings, we will utilize a <br />program developed by Innovative Design, specifically designed for optimizing the size <br />and design of rainwater catchment systems. <br />The proposed analysis will determine, for each measure, the energy savings (in dollars as <br />well as btus), CO2 savings, and nitrogen savings. This will be compared to the projected <br />cost of each measure. <br />
