Morgan Street Raleigh, NC 27603 919-832-6303 Fax 919-832-3339 April 27, 2003 Pamela Jones Director of Purchasing and Central Services Orange County 132 E. 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 Padia (with Padia 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 dollazs as well as btus), CO2 savings, and nitrogen savings. This will be compazed to the projected cost of each measure. [/T[/i The following outlines the base audit and analysis costs that will occur, regardless of the specific measures selected. This scope assumes that there are "As-Built" plans for the facility and that additional, detailed field work is not required to determine the existing conditions.

Assuming that you want to go ahead with the majority of this analysis, we will, on your behalf submit a grant proposal to the energy office for the Living Machine and Rainwater Catchment Systems. Let me know as soon as possible if this is acceptable and what percentage of in-kind you want to list (remember that you have to be at least 25% and the more you put in the better your chances will be). I will also need to work with you pretty quickly since the applications are due May 13. We will need to coordinate quite a bit on this and we will need some information from you regarding the application. The application requirements aze enclosed. Ultimately, you will be the applicant an, in turn, need to approve everything. 0 I am not certain if this is the scope of services that you were anticipating but, from a goad quality analysis standpoint, this is what it will take. We could, of course, reduce the scope but the reliability of the cost estimates and projected savings would then be less. If we are off base, just let me know and we will adjust if we can. I will be in the office Tuesday from 8:30 until noon. Then I will be out until late Friday night. However, if you do want to gn after the grant I will need to work on it that weekend (May 3~d and 4`~. The main time that I can work on the grant will be May 3'~ though May 8~°. I will try to call you on Tuesday. Thanks again for the chance to work with you. Sincerely, ~~ e Nicklas, AIA President, Innovative Design
