LEED Certification and Building Retrofit Program:
Since 2004, the City has required all new buildings to be LEED Certified. We currently have 37 LEED buildings with plans to add more through 2020. To date, the City has invested $70 million in energy efficiency retrofits: 6 million square feet of retrofitted City facilities are expected to achieve guaranteed energy use reductions of 30%, saving over 22 million kWh of electricity every year. The City’s most recent retrofitting projects were in the Parks and Recreation Department and in the Library Department where we retrofitted 18 libraries.
LED Lighting Conversion Program:
In 2014, at the City’s request, CenterPoint began converting ~175,000 streetlights to LED technology. This project is intended to reduce the City’s streetlight energy usage by approximately 50 percent, while reducing the City’s greenhouse gas emissions by 5 percent. Although the project was supposed to take several years, thanks to overwhelming support from residents asking for lighting to be installed in their neighborhoods and a push to light up the city in time for the Super Bowl, CenterPoint is ahead of schedule.
The Public Works Department also finished replacing the incandescent bulbs at all 2,450 signalized intersections with LEDs and the City is now realizing over $3.6 million a year in savings.
