Home Weatherization

Every year, Matthew 25 hosts a team of Green Iowa AmeriCorps from the Energy & Community branch. This team focuses on energy efficiency in residential homes as well as education and community outreach programs.

Energy Saver Kits

A big part of the Energy & Community team’s job is to perform Home Energy Assessments in the Cedar Rapids area. However, due to the pandemic, these services have been suspended.

If you’d like to make your home more comfortable, reduce utility costs, and conserve natural resources, click here to request an Energy Saver Kit.

This form will allow us to collect the information needed to customize your kit. A member of Green Iowa AmeriCorps will then contact you to arrange a time to deliver the kit to your doorstep.

 

Why should I weatherize my house?

Check out the video below to learn more about home weatherization from Green Iowa AmeriCorps.

Additionally, ACH means air exchange per hour. This is the percentage of outside air coming into the house and our blower door can test this. We look for an ACH between 0.3 and 0.5. Anything below 0.3 means the house is too tight and could be potentially dangerous if you have a gas or CO2 leak as there would not be a way for it to get out. If the house has an ACH above 0.5 it can get cold or hot (depending on the season) too quickly and therefore will be wasting energy and you will essentially be paying to heat and cool the outside.

 

What’s in your kit, and why?

LED Light Bulbs

Compared to the typical incandescent light bulbs, LED light bulbs use up to 90% less energy, produce the same quality of light and last up to 25 times longer.

Low-Flow Faucet Aerators

Low-flow faucet aerators reduce the flow of water from the faucet without reducing pressure, saving both water and energy.

Low-Flow Shower Head 

Low-flow shower heads are designed to reduce the amount of water, without reducing the pressure.

Water Heater Pipe Insulation

Insulating your hot water pipes can reduce heat loss, which decreases the amount of energy needed to continue to heat your pipes.

Furnace Filter Whistle

This mechanism alerts you when you need to replace your furnace filter by producing a whistling noise. When you replace your furnace filter regularly, it increases the air quality within your house, and allows for your HVAC system (heating, ventilation, and air conditioning) to run smoothly.

Outlet/Light Switch Insulators

Outlet and light switch insulators help to reduce drafts from outlets and switches on exterior walls.

Rope Caulk

Rope caulk can be used to fill gaps around windows and doors to prevent air flow.

Expandable Spray Foam

Expandable spray foam can be used to fill larger gaps and cracks in spaces like basement foundations or attics.
