Home Energy Efficiency

Improving home energy efficiency is one of the simplest ways for residents to save money, increase comfort, and reduce everyday environmental impact. Even small, do‑it‑yourself upgrades like sealing air leaks, adding weatherstripping, or improving insulation around doors and windows can make a noticeable difference in monthly bills. Whether you are a home-owner or a renter, learning a few basic projects allows you to take control of your space, avoid costly service calls, and create a home that feels more comfortable year‑round.

Explore the pages below to learn how to do home energy efficiency upgrades on your own. Each DIY page will include the indication to look for that the measures are worth doing in your home, a priority level and difficulty level, materials needed, directions, and other tips for the upgrade. 

You can also explore the pages on No-Cost Tips you can make in your home, a deeper explanation of home energy use & efficiency, and other resources for non-DIY measures to make your home more comfortable, safe, and energy efficient.
