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
