buildings (Integrated design)
3
Barriers
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

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.

Opportunity – 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

High refrigeration needs (up to 50% of the total building energy consumption)
Simultaneous heating and refrigeration requirements
Large use of synthetic refrigerants Exothermic buildings (heat rejected by the R
system > heating requirements) High potential for energy savings and CO2
emission reductions
22
