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)
“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 and CPUC
(Coming soon to all IOUs)
SCE Mission
Comprehensive HVAC
A 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
Background
• 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
SCE Trial Overview
• Upgrade existing and “to code” Units when premium
HVAC equipment cannot be installed
• Installation of Enhanced Ventilation Measure first
opportunity
• Installation of Evaporcool Technology second
opportunity
• Combined Installation of both Technologies third
opportunity
• Both technologies provide ADR potential
• Replacement incentives: $200-$500 per ton
• Additional Incentives for enhanced technologies

EvaporCool
EvaporCool
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!

Lighting
Demand Controlled Lighting
• Retrofit to latest generation of T-8
Lamps
• Dimmable ballasts combined with
lighting controls.
• Reduce lighting energy up to 50% in
occupied spaces and in parking
structures.
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
• Flexibility to shift or shed load
– Peak load greater than 200kW - willing to sustain a load drop
up to 4 hours event
• Existing building automation system or controls infrastructure
• Most industrial loads can be simple and easy
– Stone crushing, recycling, cold storage, and public water
agencies are always reliable loads
• Mid to large size office campuses work very well (5 –10MW+ peak)
– 5% of peak load is quite easy
– 10% of peak load is comfortable
– 20% of peak load is being achieved by many accounts
