Energy Ratings and Mortgages

Home Energy Ratings

Home energy ratings provide a standard measurement of a home’s energy efficiency. New and existing homes use these ratings. In new homes rating often verify energy performance for the ENERGY STAR homes program, energy efficient mortgages, and energy code compliance.

Cornerstone can help homeowners improve their home’s energy efficiency. We use energy ratings which evaluate specific cost-effective improvements. Existing homeowners receive a report displaying cost-effective options to improve their home’s energy efficiency . Obtaining an energy rating enables the homebuyer to easily evaluate the energy performance of the homes being considered.

There are two types of ratings:

  • Projected ratings – Ratings performed prior to the construction of a home or prior to the installation of energy improvements to an existing home.
  • Confirmed ratings – Ratings completed using data gathered from an on-site inspection, which could include performance testing of the home.

Confirmed ratings involve an on-site inspection of a home by a residential energy efficiency professional, a home energy rater. Cornerstone energy raters are trained and certified by RESNET. (Residential Energy Services Network – An accredited home national consortium of builders, bankers, utilities and government agencies)

Cornerstone’s home energy rater reviews many items:

  • Insulation levels
  • Window efficiency
  • Wall-to-window ratios
  • The heating and cooling system efficiency
  • The solar orientation of the home
  • The water heating system
  • Performance testing, such as a blower door test, for air leakage and duct leakage, is usually part of the rating as well

Once the data is collected, the home is scored between 1 and 100, depending on its relative efficiency. The home’s estimated energy costs are also included. The energy rating is then equated to a Star rating system:


A voluntary partnership between the government and more than 9,000 organizations, including 2,500 of the nation’s home builders, ENERGY STAR is the government backed symbol for energy efficiency. The logo identifies new homes and more than 40 types of products for energy efficiency while offering the features, quality, and personal comfort that today’s consumers expect.

ENERGY STAR products include:

  • Appliances
  • Lighting
  • Home office equipment
  • Consumer electronics
  • Heating and cooling equipment

On new homes, the ENERGY STAR label means:

  • Significantly more efficient than standard home
  • Lower utility bills
  • Reduction in air pollution

Last year alone, Americans using ENERGY STAR saved enough energy to power 20 million homes and reduced greenhouse gas emissions equivalent to those from 18 million cars, while saving $9 billion in energy costs.

How do homes qualify as ENERGY STAR?

ENERGY STAR homes are significantly more efficient than standard homes. Home builders use a variety of features to achieve this high efficiency.

How much more efficient? To qualify, homes must be at least 15% more efficient than the International Energy Conservation Code, or 15% better than the state energy code, whichever is greater.
