Retrofit Tips
Here’s a short list of quick tips on retrofit measures that will help you achieve a deep energy retrofit for a healthier, happier, and more climate-friendly home.
Building Envelope Tips
Draft proofing.
A large and cost-effective opportunity – a blower door test will find the leaks.
Adding insulation to the attic
Attic should be topped up to at least R50.
Adding insulation to the basement.
Finishing and insulating the basement provides comfortable extra space in many houses. Codes call for R22.
Adding insulation to the walls.
Wall insulation gets little attention but is a LARGE opportunity for savings. Building Codes now call for R22 at least.
Upgrading to Energy-efficient windows & doors
Energy Star windows increase comfort, reduce bills and enhance curb appeal.
Mechanicals & Equipment Tips
Heating:
Upgrading to a heat pump
Replace the old furnace with a heat pump which can also double as an cooling appliance during the hot summer months to replace your air-conditioner. But only after completing the building envelope upgrades so it is not oversized.
Add or upgrade to a smart thermostat
A smart thermostat allows setting back the temperature overnight or when away.
Hot Water:
Upgrading to heat pump water heaters
A heat pump hot water heater can help get you house off fossil fuels and reduce water heating costs.
Adding a drain water heat recovery pipe
This clever copper pipe will save energy for the rest of the life of the house.
Lights & ENERGY STAR Appliances
Energy Star appliances & LED lighting make a real difference on the electric bill.
Renewables Tips
Solar electric panels can sometimes offset all remaining energy use in an efficient house. Their potential contribution is highly site-specific.
Pairing a home battery system with your solar photovoltaic system allows you to store excess solar energy for later use. These batteries can also supply power during electrical outages and charge up during cheap off-peak hours if your local utility uses time-of-use rates.
A solar hot water system can meet up to half your hot water needs.
