Energy Efficiency Auditing questions, answered by experts

Replacing a window frame will improve your home’s energy efficiency if the old frame is cracked or damaged in a way that allows unconditioned air from the outside into your living space or if you upgrade to a more energy-efficient window frame material. Aluminum is the least energy-efficient window frame material, followed by vinyl and wood. Fiberglass and composite frames are the most energy-efficient.

While parts of the appraisal are out of your control, there are some things you can do to potentially raise the home’s value. You can make necessary repairs and upgrades before the appraiser visits—an appraiser can only value what is currently part of the home, not its potential. You can also provide the appraiser with the cost of recent upgrades. The appraiser will likely increase the value of your home by about 50% or more of what you paid for those improvements.

Installing weather stripping or upgrading to insulated panels can improve efficiency.

Modern windows provide enhanced UV protection, improved heat retention, and cooling efficiency, contributing to overall household energy savings.

Generator size requirements vary wildly among properties, but typical generator sizes are listed below based on home square footage:

  • 1,000 sq ft: 6–9 kW

  • 1,500 sq ft: 7–10 kW

  • 2,000 sq ft: 10–14kW

  • 2,500 sq ft: 12–16kW

  • 3,000 sq ft: 16–20kW+

Unfortunately, home square footage isn’t always a good indicator of generator size requirements. Instead, you should call in a professional to discuss which items in your home you’d like to run via your generator. They can calculate peak and average consumption for those items and then size your generator appropriately for optimal performance.
