King Street Hillsborough, NC 27278 Ms. Jones: I look forward to the opportunity to work with Orange County on such a challenging as well as exciting project. The sustainable goals put forth by your commissioners, for the old Cedar Grove School, are wonderful. I would be very proud to be a part of making them come true. I thank you for the opportunity. The following presents a proposed list of optional strategies which Harshad Podia (with Podia Consulting) and myself feel are opportunities which should be analyzed. Depending upon your budget for this initial work, you could decide upon the level of effort desired. In our very tentative review, we have also tried to place these option in order in terms of relative potential benefit (both energy dollar savings and environmental impact). We have also identified a fee associated with each item that would allow us to analyze the particular item in relationship to the overall project. To complete the following work we will, from an energy perspective, require that the current building be input into a total building energy simulation program. To accomplish this analysis we use the best program available -DOE II. To additionally simulate any of the daylighting options, we use a program called DAYLITE which allows us to simulate the daylighting contribution at numerous points within each individual room, all day long, 365 days a year. To determine the actual projected lighting and cooling savings, this DAYLITE program output is, in turn, input into DOE II, which accounts for the savings occurring from the particular daylighting option in relationship to the other building dynamics. To calculate the rainwater savings we will utilize a program developed by Innovative Design, specifically designed for optimizing the size and design of rainwater catchment systems. The proposed analysis will determine, for each measure, the energy savings (in dollars as well as btus), C02 savings, and nitrogen savings. This will be compazed to the projected cost of each measure.
