Council Chambers get energy-efficient lighting retrofit

Guelph Council Chambers was retrofitted with new light emitting diode (LED) lighting to replace burned out and faded light bulbs. The new LED lighting will save about 8,500 kilowatt hours (kWh) annually — roughly the amount of energy used by one household over three months, which reduces our energy costs by about $1,250 per year. An additional $5,000 will also be saved annually in maintenance costs, based on 2,000 hours of operation. The retrofit replaced 91 incandescent bulbs and 136 fluorescent lamps over three days and cost $19,870. Facts about LEDs use 46 per cent less electricity, last longer and need less maintenance produce less waste heat and that means less energy is needed to cool Council Chambers improve light quality: they’re brighter and don’t… Continue reading Council Chambers get energy-efficient lighting retrofit

First LED traffic signal replacements underway since original upgrade in 2006

LED upgrades paid off faster than anticipated Guelph, Ont., January 18, 2017—The City of Guelph is starting the first city-wide replacement of LED traffic signal bulbs since they were installed over 10 years ago. The City expected a four–year payback period from the LED traffic signal upgrades, but saw a much shorter, two–year payback period, and continues to see operational savings every year. “The City has saved 90 per cent a year on energy costs for traffic signal operation since we replaced incandescent bulbs with LED lighting,” said Steve Anderson, Supervisor of Traffic Engineering with the City. Previously, traffic signal bulbs had to be replaced twice a year. LED lights are generally maintenance free for 7-10 years, which reduces operational costs for bulbs and replacement… Continue reading First LED traffic signal replacements underway since original upgrade in 2006

City tests LED street lights

Energy efficient, low maintenance LED street lights can save Guelph $750K annually Guelph, Ont., January 18, 2016–The City and Guelph Hydro are testing a number of LED options on residential Guelph streets to determine the best energy efficient alternative to the City’s current high pressure sodium (HPS) street lights. “The City is in a position to save about 50 per cent of its 13,000 street lights’ energy use, about $750 thousand dollars in annual cost savings, by switching out Guelph’s HPS  street lights with LEDs,” said Alex Chapman, the City’s program manager of Corporate Energy. “LED lights last longer, use much less electricity, require less maintenance and provide better illumination than the HPS lights we’re currently using.” During the test period, which runs until March, the City… Continue reading City tests LED street lights
