What we will cover
  • Barriers
  • Opportunities - Equipment
  • Energy Star Criteria
  • Other Premium Efficiency Criteria
  • Early replacement
  • Putting it Together
  • New Buildings - High performance new 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

4
Opportunities
  • ENERGY STAR Criteria
  • Office equipment (computers, monitors, imaging
    equipment)
  • Appliances (commercial refrigeration, vending
    machines, commercial clothes washers, water
    coolers, commercial cooking)

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.

Opportunities
  • Other Premium Efficiency Equipment Criteria
  • NEMA Premium Motors (CanMOST)
  • 80 Plus (80 efficiency internal power supplies)
  • Near Condensing and Condensing Boilers (NRCan
    list)

    many times the purchase cost.
  • Built from superior materials and
    design-optimized, premium-efficiency motors can
    also improve your systems reliability.
  • CanMOST helps you
  • Find the most energy efficient motor for your
    application.
  • Quickly and easily determine the energy and cost
    savings associated with any motor purchase,
    repair or replace decision.
  • Features
  • Comprehensive database of 43,000 motors
  • Energy savings calculations
  • Greenhouse gas reductions calculations
  • Lifecycle cost analysis
  • Specialized parameters (e.g. centrifugal
    speed/load correction)
  • Canadian utility rates dollar values

Opportunity - 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.

80 PLUS Potential
Potential Savings Estimates Energy Savings
GHG Emissions (GWh/yr) Reductions (Kt
CO2e) 2006 17 7 2007 50 21
  • For the 2-year duration of the program
  • Assumes
  • 7 market penetration in year 1 and 14 in year
    2.
  • Standard rate of 430 kgCO2e/kWh
  • 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.

14
Opportunity 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

15
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
