Energy Conservation & Solar

ACC’s Greenhouse Gas Inventory indicates over 46% of ACC’s GHG emissions are coming from purchased electricity.  ACC has implemented a variety of initiatives to save energy and make the district's building more sustainable.

HVAC Systems

ACC has upgraded HVAC systems to more energy efficient units across all campuses.


ACC is phasing out inefficient incandescent bulbs throughout the district to abide by the Energy Independence and Security Act.

ACC had adopted energy efficient Fluorescent Tube Lighting and Compact Fluorescent Lighting (CFL) in most areas already. We will be replacing remaining incandescent bulbs with energy efficient CFL or LED lighting.

The Rio Grande Campus has recently reduced energy consumption of 250 hallway lights by 45%.  T12 fluorescent lights were replaced with more efficient and luminous T5 models.


ACC reduced energy consumption by a total of 69% through the Northridge Campus Outdoor Lighting Project.  In addition to saving energy, this project uses a ROAM system to dim unneccessary lights during unoccupied times and enhances safety and security in the parking lot by improved light quality.  This project is one of the largest installations in the nation among other LED outdoor lighting applications.  Some of the improvements included:

  • Replacing 104, 1,000-watt high pressure sodium lights in one parking lot with 104, 265-watt LED lights.
  • Replacing 32, 400-watt metal halide lights with 32, 250-watt LED lights.
  • Replacing 47, 175-watt metal halide lights in the courtyard with 47, 72-watt LED lights.
  • Replacing 21, 174-watt metal halide lights around the building perimeter with 21 53-watt LED lights.

Desktop Lamps

ACC's Office of Energy & Sustainability offers LED desktop lamps to eligible faculty and staff while supplies last.  This lamp uses less energy than current desktop lamps, improves lighting, and saves money.  Submit your application for a new desktop lamp.

Occupancy Sensors

ACC has, and continues to, install occupancy sensors in several building across the district.  These sensors shut off lights once individuals have vacated a room or hallway.

Solar Panels

Green Cleaning

ACC started Green Cleaning practices in 2010. While occasional special cleaning might be necessary, our ordinary cleaning will be maintained to a higher and safer standard.

Custodial services are maintained at the minimum level of APPA II with environmentally preferable products including:

● GreenSeal Certified Cleaning Chemicals

● EPA Preferred Disinfectant

● Reusable Microfiber

● Touchless Foam Dispenser - uses 1/2 the soap of conventional soap dispenser

● Touchless Paper Towel Dispenser - saves up to 30% of paper towels and uses 100% recycled paper

● Coreless Multipack Toilet Paper Dispenser
