Award Description: The City of Roanoke will use Energy Efficiency & Conservation Block Grant Recovery Act funds to implement a broad based program of resource conservation and energy efficiency measures. These measures will reduce the City's carbon footprint, create/preserve jobs, expand energy efficiency measures to include every city facility, allow implementation of a comprehensive energy conservation program and reduce operating costs. The program will integrate four (4) distinct projects that will have an immediate, substantial impact, resulting in sustainable and measurable energy savings: (1) City-wide LED Traffic Signal Head Replacements, (2) Retrofit of T-Lighting in the Courthouse (a municipal facility), (3) Installation of Digital Controls in the Courthouse, and (4) LED Lighting Retrofits for City of Roanoke Market Square Garage. As it relates to Project #1 (City-wide LED Traffic Signal Head Replacements), the City will replace incandescent traffic signals with LED traffic signals at 80 intersections. LED traffic signals use approximately 70% less electricity saving 200,000 kWh per year. Based on Roanoke's prior experience with changing signals from incandescent to LED lights, the project will result in a reduction of $40,000 - $50,000 per year, giving this element of the program a Return on Investment (ROI) of 3% at the conclusion of the EECBG funding initiatives. Savings on energy expenditures will also continue for serveral years following installation and at the 5-year mark, the project will have achieved over $200,000 in savings on electricity expenditure, an ROI of 13.3%. Project #2 (Retrofit of T-Lighting in the Courthouse) will result in the purchase and installation of new T-8 lighting to replace the existing F-40 lights in the Courthouse. This retrofit will exchange 2,500 F-40 lights for high efficiency T-8 lights, thus providing a higher quality of illumination and resulting in an estimated energy cost savings of $4.20 per kilowatt hour. A proposal from an independent contractor estimated a payback in six years (by 2015). Project #3 (Installation of Digital Controls in the Courthouse) will result in the purchase and installation of digital controls for the courthouse.The controls will be used to control five (5) air handlers, two (2) boilers, one (1) chiller and associated chill water, condenser water pumps and cooling towers. The controls will communicate via BACNET protocol and will report back to a network controller, which will have time of day scheduling for occupied, unoccupied and alarm capabilities. The five (5) supply and five (5) return fans will be replaced with energy efficiency motors along with installation of new variable frequency drives. Due to the size of the air handlers and combined load, significant energy will be saved with Direct Digital operation of the new equipment. Project #4 (LED Retrofits of the Market Square Garage) will replace illuminated High Pressure Sodium (HPS) and Metal Halide (MH) lighting with LED lighting in the Market Square Garage which will reduce energy costs and maintenance for public garage lighting and use significantly less electricity than traditional fixtures. Estimated annual energy cost savings is $26,020. In addition to the energy savings, the life of the LED fixture is 3 to 5 times longer than the current lighting in the Market Garage. Due to the long service life, the use of LED fixtures can eliminate the need for bulb replacements for the service life of the fixture, thereby saving not only the cost of the bulbs, but also the cost of the labor and materials required to change them. This aspect of the project will generate another $40,000 ($10,000 per year) in savings for the City over the next four (4) years.
