Morgan Street Raleigh, NC 27603 919-832-6303 Fax 919-832-3339 Apri127, 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 and 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 I 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 inputted 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 inxelationship 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), CO2 savings, and nitrogen savings. This will be compared to the projected cost of each measure. 4 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 are enclosed. Ultimately, you will be the applicant an, in turn, need to approve everything. I am not certain if this is the scope of services that you were anticipating but, froth a good quality analysis standpoint, this is what it will take. We could, of course, reduce the scope but the reliability of the cost estimates and pr~jeeted savings would then be less. If we are off base, just let me know and we will adjust if we can. l will be in the office "fuesday from 8:30 until noon. Then I will be out until late Friday night. 1-lowever, if you do want to go after the grant I will need to work on it that weekend (May 3`~ and 4th). The main time that I can work on the grant will be May ~`~ though May 8th. 1 will try to call you on Tuesday. Thanks again for the chance to work with you. Sincerely, ~ , ke Nicklas, F`AIA President, Innovative Design Orangs County - Living Machine Proposal innovative Design Design Proposal for a Living Machine at grange County's Northern Human Services Center Northern Human Services Center The site for the project is the Northam Human Services Center, boated off Si6~Mnoaef~~Cedar Grove, Orange County. Previously an elementary school, the building is now used as government offices by Orange County. Sited on the southwest comer of the bt EB a softball field, shared with the community. Orange County wishes to renovate the facility in a manner that h~hlights various sustainable features. and sets an example fw the region. Several sustalnabis features are currently being evaluated by the County, inducting daylighttng and energy-eficisnt building shell strategies, energy-efifdent mechanical and electrical systems, green building produdsR sustainable site design and water conservation and management systems. As part of the renovation and extension of the facility, the existing wastewater treatment system. that presently processes 2,700 galbns per day (gpd), is to be expanded to a fatal treatment capacity of 6,000 gpd. To accomplish this treatment in an environmentaNy sound manner, Orange County is now desiring tD implement an innovative, natural and biologically diverse wastewater treatment system equal th or equivalent to a Wing Machine approach. This innovative, natural wastewater and reclamation system uses plants in water gardens to naturally perform water purification procxsses. Project Scope Innovative Design's team will design. assist in biddlttg, and provide construction administration services to Orange County in implementlng a Living Machine type system capable of treating up to 6,000 gpd of wasth. The water will be biologically treated through a system of ponds. The tent is to have the treated water disposed of onsite. The most 8kely approach to be incorporated for this project is a tidal vertical flow ('iVF). The TVF constructed wastewater treatrnent wetlands operate by cydic flooding and draining through a media bed wrth cycle periods of a day or less. The cycle period of a day or less distinguishes these technobgies from other flood and drain systems. The tertiary LTeated effluent would be discharged into either a (1) sut>surfaoe nitrification fiekd, (2) subsurface drip irrigatbn system or (3) surface drip irrigation system. The choice of these three options will depend upon the first phase of tMa project; a detailed assessment of the existing. site and the establishment of priorities of County.

This work will be completed within 40 days of approval of contract. Task 1.1 Biting Analyst and Preliminary Layout Within one week of signing contract, the wuniy will provide our team with the already completed surveys that locate the existing wells, septic fields, topographic characteristics, flee focadons, buildings, outdoor structures, utilities, setbacks, property lines, and currant play areas and the ball field. Add'Rionally, they will provide our team with information on the existing well characteristics (flow rate, depth, water contaminants). Based upon initial site evaluations, discussions with your county officials, and input from state agencies, we will identify potential strategies and the corresponding potential krcatbns of the various system components. Tssk 1.2 Solt. Hydraulk;, and FNk! Layout This work ir>cludes technical soils and site evaluatbn of the options as they relate to regulations required for subsurface systems; hydraulic testing of soil using an Arnoozenteter (as required for systems greater than 3,000 gpd); one gsoprobe boring th groundwathr, hydraulic mounding modeNng; and the nitrifiication field layout and specilk:atlons for the 6,000 gpd system. The evaluation will also address your ooncem regarding any potential impact the system -might have on the existing trees. Task 1.3 Evaluation of Exiting PlumbMg and Etctrical This work wNl consist of a detalted evaluation of the existing plumbing, septic, and well systems in order to determine the optimum connection points and any n~iping naquirements. The current and anticipated electrical system will also be evaluated as it relates to the andcipeted electrical service demands. , We wiM provide you with a report summarizing our conclusions. Task 1 A Evaluation of Functional and Educational Impacts We will analyze the site from a fixxdional and an educational standpoint, to determine the best opportunities and limitations for locating particular components of the system. 1Ne will evaluate the maintenance, security and safety issues and provide you a report summarizing our recommendations. Task 1.6 i~nliminary Review with County and Stab Agencies Although there will not be enough of the design completed at this point to guarantee final acceptance, we will review the proposed strategy with the appropriate state and county agendas as to determine their general acceptance- of our appros~ch.
