energy awareness
Energy Awareness
  • Global demand for all energy sources forecast to grow 57% over next 25 years
  • U.S. demand for all types of energy expected to increase 31% within 25 years
  • By 2030, Asia will use 56% of the world’s energy
  • U.S. electricity demand will grow by at least 40% by 2032.
  • New power generation equal to nearly 300 power plants (1,000MW) will be needed to meet electricity demand by 2030.
  • Currently, 50% of U.S. electrical generation relies on coal (fossil fuel) while 85% of U.S. greenhouse gas emissions result from energy-consuming activities supported by fossil fuels.

california energy efficiency strategic plan 2008
California Energy Efficiency Strategic Plan (2008)

“The goal is for California’s energy to be adequate,

affordable, technologically advanced, and

environmentally-sound…Cost effective energy

efficiency is the resource of first choice for meeting

California’s energy needs. Energy efficiency is the

least cost, most reliable, and most environmentally sensitive

resource, and minimizes our contribution to climate change.”

sce mission
SCE Mission

Comprehensive HVACA vision for an integrated HVAC portfolio driving market transformation

SCE Comprehensive HVAC exists to:

  • support the HVAC goals of the CPUC
  • provide a catalyst for continuous improvement
  • demonstrate fiduciary responsibility to SCE customers
  • Starting with packaged AC equipment
  • Among Southern California businesses, HVAC is typically the largest consumer of energy, the single largest contributor to peak demand and the highest operating expense.
  • An optimized HVAC system reduces energy consumption, saves money, and prevents costly system breakdown.
  • Improved HVAC operation is a leading opportunity for improved energy efficiency, reduced peak power demand, and cost savings.
  • CPUC directed implementation new HVAC program amongst IOU’s to support California’s contractors

Remediation of Service and Operational Issues


Hot outside air is cooled as it passes through the EZ-Frame, before it reaches the condenser coils.

This allows the system to operate as though it were cooler outside than it actually is.

On recent 100 degree days (73 wet bulb), in a humid Southeastern U.S. climate, the leaving air temperature of the EvaporCool system entering the condenser is 79.2 degrees!

what is demand response
What is Demand Response?
  • Mechanisms used to encourage consumers to reduce electricity during times of peak demand; high wholesale prices, or grid emergencies
    • Customers temporarily shed or shift loads in response to a request made by utility
    • Useful in controlling overall energy procurement costs and avoiding emergencies (blackouts)
    • Different than energy efficiency measures
      • Energy efficiency – customers find ways to do the same thing with less power
      • DR – customers go above and beyond EE measures to temporarily curtail or shift load to different times
eventconnect share the power what makes a good customer
“EventConnect–Share The Power”: What Makes a Good Customer
