Net-Zero Energy Home
Definition A net-zero energy home at a minimum
supplies to the grid an annual output of
electricity that is equal to the amount of plug
load power purchased from the grid. In many
cases the entire energy consumption (heating,
cooling and electrical) of a net-zero energy home
can be provided by renewable energy sources.

Net-Zero Energy Home
  • Objectives
  • Linking energy efficiency/conservation with
    renewable energy development
  • Expanding the market for localized/onsite green
    power generation
  • Help resolve the issues of cost effectiveness

all customers-- commercial /industrial--with
average monthly peak demands gt 50 kW Red all
consumers (65 to 70 residential) with demands lt
50 kW. Blue Red Grey (adjusted for
distribution losses).

A natural progression in response to concerns
over energy price security, reliability and
sustainability
7
Net-Zero Energy Home Feasibility
  • The technology exists todaymuch of it in the
    province
  • Builds on the work of existing programs such as
    R-2000, EnviroHome, Energuide for Houses
  • Requires a partnership of governments, industry,
    and communities

8
Net-Zero Energy Home--Justification
  • Dual role of power plant and an effective demand
    side management/conservation program
  • Reduced dependence on expensive imported peak
    electricity. Peak load shaving
  • Reduced need for transmission, distribution
    infrastructure
  • An integrated approach to deploying available
    renewable energy technologies into Ontarios
    marketplace
  • Integrating sustainable living and sustainable
    community development

9
Net-Zero Energy Home --Technologies
  • Net-Zero Technology MENU
  • R2000 building efficiency standards
  • Energy Star Appliances
  • Photovoltaic Roof
  • Solar Thermal
  • Earth Energy Systems
  • Heat recovery technologies
  • Solar Hot Water
  • and others

Menu of options allow the consumer flexibility in
designing their Net-Zero Energy Home
  • Excess energy capacity and storage through the
    grid
  • Net-metering allowing customer to reduce monthly
    costs in half
  • Time of use metering allows consumers to balance
    energy load.

10
Net-Zero Energy Home Economics
  • The Technology Learning/Volume Cost Curve
  • Average yearly cost decline of 5 per year with
    increased market size, accelerates
    competitiveness and removes need for government
    support
  • Declining installed costs for new homes in Canada
  • PV 8.00--5.50--2.50/watt
  • Solar Thermal 4K--2K
  • Earth Energy 20K--15K
  • Typically a 10-15 year cycle before costs and
    market begin reaching maturity

Net-Zero Energy Home German Strategy

A similar strategy for NZE technologies can lead
to significant results and benefits in Ontario
13
Net-Zero Home Energy PlanBenefits to Ontario
Environmental Total GHG reductions 144 Megatons
(through to 2050) New power generation 6100 MW
(through to 2050) Conserved energy 178 billion
kWhrs (through to 2050) Sustainable urban
development Green communities Public
education/awareness Empowering
consumers Displacing fossil generation Cleaner
air, reduced smog Economic Development New
manufacturing base Upwards of 25 new PV
factories Direct PV and solar thermal related
jobs 4100 New Jobs from all related
sectors 88,000 Reliable and secure energy
supply De-centralized power
14
Net-Zero Home Energy PlanNext Step
  • What is Required of Ontario in the Short-Term
  • Support a minimum 300 Demonstration Homes
  • Size will help with exposure to markets, learning
    curve, the platform for larger scale grid-tied
    and localized green power systems
  • Provincial commitment required---6.0 Million
    over 3 years
  • Potential for co-funding with the federal
    government
  • Possible DSM funds with support of power
    companies
  • Research and market analysis of projects

15
Net-Zero Home Energy HomeGovernment
  • Federal
  • CMHC, Industry Canada, NRCan, leading supporters
  • Interest in supporting pilots
  • Provincial
  • Ontario Ministry of energy is supportive and
    poised to assist
  • Other provinces expressing interest BC, Alberta,
    Quebec and PEI
  • Municipality
  • Looking for first demonstration location
  • Exploring how municipalities can lend support
  • UtilitiesMilton Hydro

16
Net-Zero Energy Home Defining Success
  • Addressing the incremental cost of 12--15
  • Investment by consumer with a reasonable payback
  • Government assistance with phase out schedule so
    that technologies stand on their own
  • tax abatement incentives, green mortgaging
  • Provide flexibility so that no one technology or
    solution is singled out. A diversified plan
    that promotes the integration of varied
    technologies.
  • Expanding awareness and understanding
