Energy Audit and Solar Feasibility Study About the Facility Camp McDowell is the camp and conference center of the Episcopal Diocese of Alabama and was established in 1923. It is located in Nauvoo, Alabama. The camp is comprised of 80 buildings and can accommodate more than 780 overnight guests. The directors of the camp chose to engage Sain Engineering Associates, Inc. (SEA) to conduct a feasibility study for 100 kW of Solar Photovoltaic array with an opportunity to document low cost energy efficiency opportunities on the campus. Solar Analysis A third party previously recommended a 100 kW solar PV array to Camp McDowell as one of multiple energy sources to be considered in meeting the camp’s vision of becoming a Net-Zero Energy Campus. SEA’s analysis is based on the feasibility of the recommended 100 kW solar PV array. SEA engineers visited Camp McDowell to determine the optimum location and system type for this solar PV array. Feasibility for a solar array is dependent on the following factors: System selection Location Generation capacity Cost Funding After a thorough investigation of each factor, SEA determined that a ground-mounted array on one of three flat, open locations could generate 163,000 kWh annually, or 12% of estimated electrical consumption. This could save the camp approximately $16,700 in utilities each year. Low Cost Energy Efficiency Opportunities SEA also identified several low cost energy efficiency improvements during the one-day site visit. 30 buildings were assessed to seek opportunities for utility savings by making simple changes. Building types investigated included cabin and dormitories, chapels, recreation areas, an infirmary and meeting halls with small kitchens and restrooms. Recommendations, included: adjusting lavatory flow, replacing insulation, turning off day-burning lights and installing door seals. Net-Zero Energy Campus Camp McDowell ultimately wishes to become a Net- Zero Energy Campus. To address the 88% electrical consumption remaining after installation of a solar array, SEA recommends developing an Energy Master Plan. This plan will include future generating options, consideration for base load generation, energy efficiency awareness promotion, and the impact of purchasing and maintaining existing electricity distribution assets currently owned by Alabama Power Company.

Measurement and Verification Services About the Facility The Dixie Group’s Candlewick Yarns manufacturing facility primarily produces yarn for the company’s carpet business, selling to independent carpet manufacturers. Sain Engineering Associates, Inc. (SEA) was contracted by The Dixie Group to perform Measurement and Verification (M&V) of five energy conservation measures. The deliverable included five annual reports that summarized the measurement and verification baseline detailing the testing and quantification for the validity of energy conservation measures. Overall, the project achieved energy and cost savings through retrofit of the lighting system and replacement of the boiler, air compressor, unit heater and power-heat set treating tunnel. Methodology Baseline Year: The M&V baseline was determined to test and quantify the validity of energy conservation measures that were to be implemented in the Candlewick Yarn’s manufacturing facility. The baseline was developed for natural gas consumption and electricity usage. A baseline equation was found for both electric and natural gas consumption with determination coefficients of 77.48% and 75.28%, respectively. These coefficients indicated considerable correlation between the consumption and the criteria against which they were judged. Year 1 : According to facility personnel, the overall output of the plan has increased over the study period. Increased product led to more run-hours for the significant energy users of the plan, such as air compressors and cabling motors, which will result in a higher billed kWh usage. While replacing the heat-set machine and air compressor did save energy, the changes in production resulted in higher electrical usage for all other machines. The variability of the chiller made it impossible to verify the savings associated with replacing the compressor and heat-set machine without some sort of metering. Year 2: The implemented ECMs have saved money and decreased consumption of electricity and natural gas compared to the base line year resulting in energy efficiency increases. Years 3 and 4: Reports outlined savings generated from the ECMs. Technologies Evaluated and Upgraded: Boiler Lighting Retrofits Air Compressor Unit Heaters Power-heat Set Heat Treating Tunnels Download Project Profile
