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 entireenergy consumption (heating, cooling and electrical) of a net-

zero energy home can be provided by renewable energy sources.

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

Blue = Milton Hydro'stotal load curve

Grey = aggregate loadprofile of all customers--commercial /industrial--with average monthlypeak demands > 50 kW

Red = all consumers

(65 to 70% residential)with demands < 50 kW.

Blue = Red + Grey(adjusted for distributionlosses).

Net-Zero Energy Home Feasibility

The technology exists todaymuch of it in theprovince

Builds on the work of existing programs such

as R-2000, EnviroHome, Energuide for Houses

Requires a partnership of governments, industry,and communities


8/16

Net-Zero Energy Home--Justification

Dual role of power plant and an effective demand sidemanagement/conservation program

Reduced dependence on expensive imported peakelectricity. Peak load shaving

Reduced need for transmission, distribution infrastructure

An integrated approach to deploying available renewableenergy technologies into Ontarios marketplace

Integrating sustainable living and sustainable communitydevelopment

Net-Zero Energy Home --Technologies

Net-Zero Technology MENU:

R2000 + building efficiencystandards

Energy Star Appliances Photovoltaic Roof Solar Thermal Earth Energy Systems Heat recovery technologies

Solar Hot Water and others

Menu of options allow the consumerflexibility in designing their Net-ZeroEnergy 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.

Net-Zero Energy Home Economics

The Technology Learning/Volume Cost CurveAverage yearly cost decline of 5% per year with

increased market size, accelerates competitivenessand 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 andmarket begin reaching maturity

Net-Zero Energy Home German Strategy

A similar strategy for NZE technologies can lead to

significant results and benefits in Ontario


13/16

Net-Zero Home Energy PlanBenefits to Ontario

EnvironmentalTotal 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 consumersDisplacing fossil generation Cleaner air, reduced smog

Economic DevelopmentNew 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

Net-Zero Home Energy PlanNext Step

What isR

equired of Ontario in the Short-Term

Support a minimum 300 Demonstration Homeso 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 yearso Potential for co-funding with the federal governmento Possible DSM funds with support of power companies

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 issingled out. A diversified plan that promotes the

integration of varied technologies.

Expanding awareness and understanding
