Home Energy Audit

An energy audit is critical to understanding the sources of energy waste and discomfort in single-family homes, condos, or multi-family buildings. An eZing Energy Audit includes:

  • Interview with client
  • Blower door test to determine overall air leakage and to pinpoint the location and severity of leaks
  • Infrared scan to find out levels of insulation, uncover damage to insulation
  • Evaluation of mechanical equipment for age and efficiency
  • Combustion safety testing for carbon monoxide levels and natural gas leaks
  • Evaluation of windows and doors (glazing and framing type)
  • Analysis of duct system (if applicable)
  • Comprehensive report that summarizes audit results and outlines a detailed action plan that prioritizes and sequences energy improvements to be done based on their cost-effectiveness
  • A list of preferred contractors (HVAC, insulation, and air sealing) to give clients a starting place for making their home more energy efficient.

An eZing Energy Audit typically takes 5-6 hours with two energy analysts. Base prices start at $500.

Energy Consultation

For clients interested in having eZing evaluate a more specific energy issue in their home, eZing offers our Energy Consultation service. An Energy Consultation costs $250 for a 2-hour visit, and $100 for every additional hour on the job. We can visit your home with any or all of our diagnostic tools to focus only on the issues you are concerned with. This service includes a 2-4 page report.

We also observe the quality of installation and test its performance once the work has been completed. Prices depend on the scope of the job and are set at a fixed fee.

Energy audit with REM/Rate Analysis

This service includes all the components of our Energy Audit plus a computer analysis using REM/Rate.

This service is relevant for housing associations, extensive rehab planning, and documentation for energy improvement financing.
