3Barriers
- Misplaced incentives, building owners do not
install equipment - Energy small portion of operating costs
- Significant initial capital investments
- Lack of criteria identifying High Efficiency in
all product categories - Availability of product meeting the criteria or
long lead times - Confusion regarding application
- Lack of awareness of the benefits
4Opportunities

7 ENERGY STAR for Rebuilt Refrigerated Vending
Machines
- Beverage companies rebuild vending machines to
extend their life. - A vending machine can be rebuilt two or three
times and stay in service over 15 years. - US EPA has a draft criteria for an ENERGY STAR
rating for refurbished vending machines.
- Requirements
- Refurbishment centre and original equipment
manufacturer must be ENERGY STAR partners. - Rebuilt machine must meet the energy consumption
and low-power mode requirements of ENERGY STAR.

12Opportunity - 80 PLUS
- Market transformation initiative for internal
power supplies of desktop computers and
desktop-derived servers - 80 or greater efficiency at 20, 50 and 100 of
rated load - True power factor of 0.9 or greater
- Offers utilities an opportunity to secure energy
and peak savings in the Commercial /
Institutional sector - Utilities offset the incremental cost to
manufacturers by paying for each qualified PC
sold in their territories - Reduced heat loss of gt ½ means 40 increased
reliability (heat is one of the leading causes
of semiconductor failure). - 100 per repair incident
- Creates early market traction for the upcoming
ENERGY STAR specification revision.

- 2005 sales gt 3 million desktop PCs
- Sales are expected to increase by 6 per year in
2006 and 2007. - Average lifespan of a PC is 4-5 years.
14Opportunity Premium T8 Lighting
- CEE / Industry Consensus Premium Efficiency 4ft
T8 (higher lumen output) - When compared to a T12 system, electricity
savings of a high-performance T8 system can be as
high as 40 percent. - List on CEE site (soon to be on NRCan site)
- http//www.cee1.org/com/com-lt/com-lt-prod.pdf
15Opportunity Condensing and near-Condensing
Boilers
- CSA 4.9 (ANSI Z21.13) safety standard requires
that boiler greater than 300,000 Btu/hr have a
minimum combustion efficiency of 80. - Proposed High Efficiency Criteria
- Tier 1 85 - 88 (near condensing)
- Tier 2 89 and above (condensing)
- Technologies/Applications to meet these levels
- Corrosion resistant heat exchanger stainless
steel - PVC Venting of combustion products condensing
- Stainless steel chimney liners near condensing
- Condensing boilers require return water
temperatures (50ºC max) - Medium efficiency boilers require higher return
water temperature - Condensing boilers are not recommended for all
applications - Condensing boiler applications using hot water
at low temperature. - Mid-efficiency boiler applications needing hot
water at high temperature
