Energy Saving Tips for Multifamily Buildings

The following recommendations are the result of MGE's 30+ years of working with rental property owners to reduce their energy bills and improve their energy efficiency.

Reduce drafts and air leaks

  • Invest in a blower door test by a trained technician to identify where the gaps exist. Caulk, weather strip or insulate all openings and gaps.
  • Seal attic air leaks – Seal around penetrations such as:
    • attic access doors
    • chimney
    • pipes
    • electrical conduits
  • Reduce drafts inside – Seal around
    • Gas and water pipes
    • Dryer, furnace and water heater vents
    • Door thresholds
    • Windows
    • Electrical outlets
    • Any gaps identified in the blower door test

Insulate to the following minimum standards

  • Dehumidifiers
  • Dishwashers
  • Refrigerators and Freezers
  • Cable and satellite access equipment
  • Water heaters
  • Air conditioners
  • Boilers with AFUE of 85% or greater
