Sustainability

Energy and Buildings

Reduction in energy use and in the use of fossil fuels are core components of CSUN’s commitment to sustainability. These reductions can be achieved in three ways – by conservation, efficiencies, and use of renewables. The proposed plan puts a priority on those actions that will lead to conservation and efficiency savings.

Main Strategies

  1. Improve means to measure, report and communicate energy consumption at a building/unit level
  2. Improve physical infrastructure to save energy through efficiency and conservation measures
  3. Increase energy-related education and outreach to students, faculty and staff, and implement program to change behavior
  4. Increase energy supplied from renewable and clean sources
  5. Establish and implement strict building standards for new construction

Objectives for 2023

  1. All buildings to be individually metered for gas, water and electricity
  2. Retro-commissioning to be completed on all buildings by 2023
  3. Real-time and historical energy use available online to all campus community by 2018
  4. Reduction in energy intensity (energy/sq. ft.) of 15% by 2018 and 25% by 2023 over 2012
  5. Generate 20% on-site by 2018, with 25% on-site generation by 2023
  6. Increase investment in renewable energy: 10% from renewables by 2023
  7. All new buildings to meet LEED Gold or higher standard effective 2013

2018-19 Priorities and Outcomes

  • Perform a Demand Flow Optimization on one campus building.
    • Demand Flow Optimization will be piloted on University Hall in conjunction with fault detection and diagnostic analytics. Fault detection and diagnostics will also be implemented on Sequoia, Citrus, Magnolia, Bookstein and Education.
  • Complete outdoor walkway lighting retrofits.
    • 197 LED retrofit kits have been installed on all remaining outdoor walkway fixtures, reducing the energy consumption of each light by 76%.
  • Complete at least 200 indoor lighting LED retrofits or replacements.
    • Over 270 LED fixtures have been installed with daylight and occupancy sensors, replacing older fluorescent fixtures. These newer fixtures use 45% less power and respond to occupancy to reduce overall runtime.
  • Assess the potential savings in energy and water from pool covers.
    • The University Student Union is using pool covers to prevent heat loss and save energy. The pools at Campus Housing are not heated, and thus, are not covered when not in use.
  • Evaluate The Sustainability Center for Net Zero Achievement.
    • The building's solar array will have been operational for a full year as of June 18th, 2019, at which point a full net zero assessment will be conducted. Preliminary evaluation suggests that the building generated about 80% of the energy that it consumed in its first year of operation.
  • Evaluate potential for research lab energy efficiency measures.
    • CSUN has identified several technologies that could play a role in reducing lab energy consumption. The campus will be piloting low pressure drop vent hood valves and vertical sash doors to decrease effective opening size in vent hoods in one of the labs to determine total savings potential and viability for expanding the pilot program.

  Other Highlights

  • The Fuel Cell was decommissioned in August 2018 to reduce Greenhouse Gas Emissions and annual utility expenditures.
  • 1,381 fixtures in the G3 and B5 parking structures were retrofitted from fluorescent to LED lamps at no cost to the university. This will reduce their energy consumption over 30% and save over $37,000 annually.

   2019-20 Priorities

  • Launch a retro-commissioning and fault detection & diagnostics (FDD) program for three campus buildings.
  • Conduct analysis to determine feasibility of utilizing solar thermal hot water heating as a supplement for the HHW loop.
  • Conduct lighting audits for five campus buildings.
  • Pilot window films as a way to reduce heating and cooling loads of campus buildings.
