FEASIBILITY AND PLANNING EXPERIENCE

ENERGY EFFICIENCY AND RENEWABLE ENERGY INITIATIVE STUDY, CITY OF RAPID CITY; RAPID CITY, SDStanley Consultants provided mechanical and electrical engineering services to complete a review of 40 city facilities. The intent of the energy audit and review was to identify capital improvement opportunities that would increase energy efficiency and possibly use renewable energy for the city buildings. To complete this energy efficiency study, Stanley Consultants conducted an on-site survey of each building and interviewed facility managers to develop several energy conservation measures (ECM). The facilities included buildings for parks, streets, airport and golf course functions. Specialty buildings included water reclamation, landfill material recovery and composting (recycling), civic center, swim center, ice arenas and fire stations. The ECMs and renewable energy opportunities were then evaluated to determine their technical feasibility, capital investment for implementation and projected savings. From this evaluation, a simple payback was calculated and compared with the city’s goals. The types of feasible ECMs that were identified include: » Exhaust Air Heat Recovery for Composting Facility Ventilation. » Variable Frequency Drives for Fans. » Additional Roof Insulation for Various Buildings. » Waste Oil Heaters for Vehicle Maintenance Facilities. » Lighting Opportunities for Many Buildings. » Waste Vegetable Oil Recovery for Biodiesel. » Wastewater Treatment Biogas. » Landfill Gas. » Solar Thermal Water Heating For Heating And Domestic Service.
