There are dozens of projects that will improve the energy conservation of an older home. Appliance upgrades, air-sealing, or tree planting are DIY jobs that get the energy-saving job done with minimum fuss and instant gratification. Other projects, like installation of replacement heating or cooling equipment, require help. As you examine whole house systems for ways to reduce energy use, consider sustainability as well. You don’t want to do damage to the environment while attempting to be a better energy conservationist. Shoot for projects that limit waste, keep ecological design in mind, and use materials that may be repurposed. Be sure to get an energy audit to help plan your work.
