Roadmap to further cut energy cost
  • If you have a mandate to further reduce costs
  • And youve done most all you can to cut costs ...
  • To save 10-30 more, you must use latest
  • With rebates covering 50 to 100 of project cost
  • Resulting in paybacks from 12 to 36 months
  • And you can complete projects with no cash outlay.

Energy demand is rising and prices follow demand
Delivered commercial energy consumption per
capita - from DOE/EIA Annual Energy Outlook 2006
  • Department of Energy data illustrates increasing
    power demand.
  • You will not offset future cost increases with
    conventional approaches.

Only one strategy materially cuts your present
Delivered commercial energy intensity (variation
from reference case) - DOE/EIA Annual Energy
Outlook 2006
  • Department of Energy data demonstrates that only
    with the
  • best available technology can you significantly
    cut cost.

What level of savings is realistically attainable
  • Additional energy savings of 8 to 12 are being
    achieved for facilities that are already highly
  • But savings can reach 25 to 30 for facilities
    that have not yet effectively engaged in energy

Savings potential of emerging technologies
  • Save to 50 with compressor and controls
    advances, CO and CO2 sensors,
  • wireless EMS, and ultraviolet UVC.
  • Save 20 to 35 for buildings, garages, and street
    lighting with lighting controls.
  • Protect health with ultraviolet emitters to
    destroy DNA of virus, bacteria, mold.
  • Eliminate A/C coil cleaning cost with UVC
    emitters to keep coils clean.

CB Richard Ellis"Your program not only
produced rebates, but it led to many projects
that otherwise wouldn't have happened. You helped
us quantify the opportunities and then guided us
through to their completion..."
Trammell Crow Company"We consider this a
unique approach to utilize our relationships and
infrastructure to benefit our clients and to
significantly expand energy efficiency throughout
our client base."
Charles Dunn Real Estate Services"Your
program and its personnel became an invaluable
resource to us in identifying and implementing
opportunities to reduce energy cost and
receive very attractive rebates."
California Energy Commission"The diversity of
so many energy technologies was another added
value. EIG's guidance led to participants taking
a more comprehensive approach to energy
efficiency BOMA members engaged in a wide
variety of energy projects that reduced peak
period demand by 17,000 kilowatts."

Globalight voltage and current regulator
  • The Technology and Improved Power and Lighting
  • A toroidal transformer and control system slowly
    and smoothly reduces voltage and current from the
    power distribution system to lighting fixtures.
  • Design is matched to ballast type (s) and ballast
    factor, light levels, voltage, lighting system
    condition, manufacturer warranties and IES
  • Globalight reduces harmonics, improves lamp
    current crest factor and provides proper lamp
    electrode temperature.
  • Lighting is visually unchanged due to the
    improved power quality and the gradual power
    reduction process.

HVACR cycle control manager
  • The IntelliCon
  • IntelliCon provides energy management
    intelligence to equipment that is typically
    simply cycled on and off according to fixed set
  • The opportunity to reduce costs
  • HVAC systems are sized to meet worst-case load
    conditions, which occur only a small percentage
    of the time.
  • IntelliCon supplements the antiquated on/off
    action of the thermostat or burner (even smart
    ones) with analysis and control of a computer.

HVACR cycle control manager
  • Taking advantage of excess capacity and thermal
  • The physics of thermal inertia, under reduced
    demand, cause space that has been cooled or
    heated to gain or lose temperature slowly.
  • Each cycle, IntelliCon considers current demand,
    resistance of a large thermal mass to change and
    excess HVACR capacity.
  • IntelliCon determines how long each off cycle
    may be extended, while maintaining temperature
  • Due to excess capacity, any fractional
    temperature change is made up in seconds once
    compressor cycle begins.
  • This is a dynamic process each cycle, based on
    changing real-time conditions, unlike a fixed
    thermostat setting or a timing device.

A/C ultraviolet (UVC) emitter technologyInstalls
at A/C coil to cut energy cost, improve IAQ,
eliminate coil cleaning
  • Florida Hospital's experiences have shown UVC
    emitters at the coil enhance IAQ and infection
    control, while saving maintenance and downtime.
    The substantial energy savings are a great
    bonus. Florida Hospital, Orlando, Florida

UVC installation downstream of A/C coils

the spread of infectious disease through A/C
delivery system
  • UV disinfection works by penetrating cell walls
    of pathogenic organisms and structurally altering
    DNA, thus preventing cell replication.
  • U.S Environmental Protection Agency

UVC light is so intense that it destroys DNA of
viruses and other microorganisms
Steril-Aire A/C ultraviolet emitters
  • All A/C attracts mold to reduce building
  • Operating environment of a/c attracts
    microorganisms, which are microscopic and results
    in coil fouling of clean appearing coils.
  • Coil fouling reduces efficiency, requires coil
    cleaning, reduces IAQ with bacteria and viruses
    causes disease, lost productivity and
  • UVC destroys microorganisms to improve
  • Ultraviolet-C emitters at coil attacks the DNA of
    these microorganisms, cleaning them from the coil
    and destroying their ability to replicate.
  • This protects against infectious disease, greatly
    improves IAQ, returns coils to near original
    design efficiency and eliminates coil cleaning.

Ventilation control CO2 sensor technology
Elimination of excess outside air ventilation in
City of Seattle buildings
  • The City of Seattle has standardized on the
    AirTest CO2 sensor although there was
    significant savings on cooling cost, the big
    savings was on heating costs. Seattle City

CO2 sensors placed in zones throughout building
for Demand Control Ventilation
Ventilation control CO2 sensor technology
Elimination of excess outside air ventilation can
save up to 20
  • The cost for heating or cooling of excessive
    levels of outside air for building
    ventilation can be up to 20 of HVAC cost.
  • Occupancy variations and excess ventilation
    over design levels exist in most buildings.

CO2 sensors for demand control ventilation
  • Building air intakes are not measured
  • Most buildings do not measure or control the
    delivery of outside air.
  • The use of excessive amount of outside air
    results in major energy cost.
  • Most buildings are over-ventilated
  • Excessive ventilation often is 200 to 400 in
    excess of actual need.
  • Buildings with occupancy swings incur significant
    added energy cost.
  • CO2 sensor system can eliminate excessive outside
    air use
  • CO2 sensors determine real-time occupancy
    throughout the building.
  • System adjusts outside air to match the need and
    cut HVAC cost 5- 20.

Wireless lighting and HVAC EMSSmaller buildings
can now cost-effectively take advantage of EMS

  • Total demand was reduced from 67 kW before CO
    sensor installation to 7 kW after
    installation, a reduction of 90. The project
    had a simple payback of 12 months. Trident
    Center Project Summary, California Energy

Control unit
Garage fan CO sensor and VFD system
  • Code requirement for garage exhaust fans and
    actual needs
  • Garage exhaust fans typically run continuously
    during all periods when garage is open to protect
    against unhealthful build-up of CO.
  • Generally, it is only during heavy traffic
    periods when CO might rise to a level that would
    require the use of the fans.
  • CO generally reaches levels that would require
    ventilation only approximately 10 of the time of
    garage operation.

Garage fan CO sensor and VFD system
  • CO sensor system can eliminate up to 90 of fan
    energy use
  • City codes authorize CO sensors (often combined
    with VFDs) to operate fans only when necessary to
    keep CO from reaching unhealthful levels.
  • VFDs on fans maintain constant base level of
    ventilation and only increase fans to levels
    necessary if CO is present.
  • New electrochemical sensor has 5 year rated
    sensor life and has a replacement cost of only
    70 after 5 years.

Oil-free refrigerant compressor technology
Turbocor oil-free compressor retrofit reducing
HVAC costs to 50
  • This revolutionary compressor technology provides
    efficiencies up to 30 better than any other
    compressor in its size range in addition to being
    extraordinarily quiet and virtually vibration
    free. 2003 AHR Expo Innovation Awards
