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 entireenergy consumption (heating, cooling and electrical) of a net-
zero energy home can be provided by renewable energy sources.

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

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 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

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
