Multi Family


Apple Energy Group recognizes the unique requirements of performing Multi-Family audits.  Having performed Multi-Family audits and trained Multi-Family auditors in numerous climate zones, AEG has the expertise and experience to evaluate the building performance of individual Multi-Family units and Multi-Family complexes alike.  Our auditors understand the ways in which a wide variety of both centralized and decentralized systems interact to affect the energy flow of multi-unit buildings.  As a result, AEG delivers a thorough energy analysis that enables residents and complex owners to identify ways to stretch their energy dollars further through strategic investment.

What kinds of tests are run during an Multi-Family Energy Audit?

  • Blower Door Test measures air tightness to identify leaks and evaluate the airflow within the home
  • Duct testing to find leakage within the HVAC system
  • Combustion Testing of gas appliances to ensure they are running safely and efficiently
  • Property owner, maintenance, and resident interviews to assess usage and reoccurring issues within the home
  • Unit/Complex walk through to evaluate any potential problems
  • Insulation assessment
  • Lighting and appliance assessment
  • Health and Safety Inspection
  • Infrared camera test to see possible areas in need

“I have been associated with Apple Energy for a number of years and with Greg Hall personally over the same time period.  During this time period, I have had the opportunity to work with Greg and Apple Energy in several business areas.  I have always been impressed with the professional nature of his company and especially the individuals who are apart of his Apple Energy team.  I am also very impressed with Greg's ability to attract and hire quality young enthusiastic individuals who support his business development programs, while maintaining an extremely capable and experienced technical training staff. These attributes of Apple Energy along with Greg's ability to set strategic objectives create a very dynamic business entity.”
