What is Home Performance?

Home performance is a comprehensive whole-house approach to identifying and resolving efficiency, comfort, health and safety issues in the home.  Similar to a car’s performance, a building’s performance is determined by how well the integrated systems are working in conjunction with one another.  A trained home energy auditor uses diagnostic tools to assess a home’s performance by:

  • Collecting valuable data such as utility information, customer concerns, previous measures, remodeling history, age of appliances, etc.
  • Carrying out detailed analysis of every energy attribute of the home home including, construction assemblies, insulation values, fenestration, ventilation, lighting, appliances, attic and crawl space conditions,
  • Conducting science-based diagnostic testing using state-of-the-art equipment to determine the air leakage rates of the building’s shell and distribution system(s)
  • Testing combustion appliances to determine safe operation and performance

Home performance assessments are performed using strict diagnostic testing requirements set by the California Energy Commission and the Building Performance Institute.  Once a thorough energy efficiency analysis has been conducted, a software model is generated to determine the most cost-effective solutions for the customer.    The purpose of home performance analysis is to provide a comprehensive strategy to improve the comfort, health, safety and efficiency of the home.  Once a customer has a complete understanding of what’s going on in the home, he or she can make informed decisions about getting the biggest return on their investment, whether its based on cost-savings, enhancing comfort, improving safety, or all three.
