It is predicted that global energy demand may double by the year 2050. Energy consumption has far reaching effects on the environment and on our health. Consequently, Pepperdine continues to maximize energy efficiency. Dating back to 1986, Pepperdine has regularly evaluated the Malibu campus for ways to reduce overall energy consumption. The resulting policy and operational changes have conserved energy throughout the campus. This represents one of the more challenging aspects of sustainability as energy consumption connects in some way with all of our sustainability practices and campus operations from transportation, to our current construction projects, to our food and water consumption.
Pepperdine utilizes an Energy Management System (EMS) to control most of the HVAC equipment, some lighting on campus, and to monitor our waste water flow station. Pepperdine can monitor and make adjustments to equipment by any computer on or off campus. The EMS incorporates energy saving techniques which include:
The EMS gives Pepperdine the ability to monitor and make changes quickly and keep our students, faculty, and staff in as much comfort as possible while minimizing the amount of energy used. The EMS also provides troubleshooting capabilities so that most problems can be analyzed and corrected quickly.
Through Southern California Edison, 19% of our electricity comes from renewable resources. The renewable energies are derived from five sources, which include 29% wind, 53% geothermal, 6% solar, 5% biomass, and 7% small hydro. The University's endowment is also invested in renewable energy funds.
Pepperdine's energy performance standards go beyond code for all buildings. Both new construction and remodel projects are assessed for ways to incorporate sustainable energy features into the facility. Not every measure is included in every building, but where feasible and complementary to the facility's purpose, such measures are incorporated. These include:
Heating and cooling is the largest energy consumer within most buildings. While estimates vary, heating and cooling systems can account for up to 56% of a buildings energy consumption. Pepperdine seeks to mitigate and minimize this potential by regularly evaluating the HVAC systems to ensure their energy efficiency. The efficiency of Pepperdine's HVAC systems is enhanced through:
Lighting within an environment has profound effects on health, safety, morale, comfort, and productivity. It is imperative that we provide good light quantity and quality while also conserving energy. Currently, 99% of all lighting on the Malibu campus is energy efficient. A campus wide lighting audit in 2002 resulted in of the following changes, which are representative of the types of measures implemented around campus:
The 2002 lighting audit alone resulted in the annual conservation of over 325,000 kilowatt hours. The savings would power about 37 houses for an entire year.
ENERGY STAR is a joint program of the U.S. Environmental Protection Agency and the U.S. Department of Energy which strives to help people save money and protect the environment through energy efficient products and practices. In order to reduce the energy needed to run appliances on campus, approximately 30% are ENERGY STAR rated.
