Specialist High Skills Major Energy Efficiency Training Awareness featuring the Energy Star Program

What is Energy Efficiency? Means conserving energy by…  Using less energy  Using existing energy more effectively Like time and money, energy can be used effectively or squandered. What everyday examples can you think of, of Energy wastage? Of effective use?

Why Energy Efficiency?  Energy costs everyone $$$$$!  Shortages of energy  Environmental impact  Public Health

New House Construction & Renovations  Energy Efficient products… “green”  Improved installation quality  New installation techniques  Testing But what standard can be used to compare One house with another?

Energy Star Program for new homes  International symbol measuring product energy efficiency  International program developed in US by the EPA in 1992  In Canada since 2001  New homes can receive symbol in 2005  In 2007 program piloted in Ontario & Saskatchewan  Administered by Enerquality Corporation

Success – media Over 700 newspaper articles since pilot launch. Q. What is the most common upgrade to new houses in Ontario? SPECIALIST HIGH SKILLS MAJORS (Construction) © EnerQuality Corporation 2008 A. Granite countertop

House Performance Goals House Performance Goals Up to 30% less energy consumed than a house built to the minimum Ontario Building Code 2006 Up to 1,200 kWhs reduction in electricity use Up to 3 tonnes reduction of greenhouse gas emissions SPECIALIST HIGH SKILLS MAJORS (Construction) © EnerQuality Corporation 2008

How it works Homes can only receive an ENERGY STAR ® label if they have been enrolled. Enrollment is $100 by the builder when the house is sold Enrollment provides the homeowner, on behalf of the builder, an ENERGY STAR ® Homeowner’s Package which includes the following items: –ENERGY STAR Qualified New Home label –ENERGY STAR Qualified New Home Certificate –Homeowner’s Letter from NRCan –“Look for ENERGY STAR ® Product Guide” –“Tips to help you… Conserve Energy and Save Money” –ENERGY STAR ® Plaque (exterior application) SPECIALIST HIGH SKILLS MAJORS (Construction) © EnerQuality Corporation 2008

SPECIALIST HIGH SKILLS MAJORS (Construction) © EnerQuality Corporation 2008 Insulating Any Questions??

Other important facts about insulation…  The Ontario Building Code required a minimum standard of R- 19 in walls. How is this achieved in our house? The minimum standard of insulation in attics is R 40 How was this achieved in our house?

 Are there any other energy efficient products that were used in our house that haven’t been mentioned?  Once the house is built what products can homeowners purchase to add to energy conservation in the home?
