AMERESCO4 Green . Clean . Sustainable Color Changing LED Lighting Retrofit Strategy: - Existing alcove recessed can fixtures with metal halide lamps in suites 12-15 were replaced with color changing LED fixtures. Reflective film was installed on the windows to reflect color changing LED light. - Existing LED floor fixtures in the pavilion canopy were replaced with color changing LED flood fixtures. The new fixtures are higher wattage to increase light levels. How Savings Were Determined —The savings were initially determined by utilizing wattages provided by the manufacturers and data from past projects. Additionally, burn hours were assumed through information provided by facility personnel, industry standards, and site data collection. These variables were used to calculate the electricity consumption and demand savings from reducing lighting wattage in the facility. Measurement and Verification — The M&V approach for the Lighting Upgrades ECM is based on IPMVP Option A. This approach consists of taking measurements of actual wattage consumption on a sample of the most common fixture types installed as part of this project. The electrical contractor utilized a true RMS meter to obtain these measurements. Once measurements of actual fixture wattage were obtained, Ameresco grouped the fixture types together and calculated the actual wattage associated with specific fixture types. These wattages were then inserted back into the original spreadsheet calculations to determine the Actual Savings. A table of the lighting measurements is included in the Appendix. Since wattages are very consistent and burn hours do not change from year to year, the savings will be realized throughout the full term of the guarantee as long as the city continues to repair burned out fixtures with the same lamps and ballasts that were installed as part of this project.
