Smart Builders – Smart Choices – Real Value

E2 Technologies created their Energy Smart Home program to tailor to the needs of the building community. Below are several options associated with improved home performance that builders can choose from:

Energy Code Compliance – Ensure home meets local energy code requirements

Quality Assurance – Independent Third Party onsite Inspection and testing that hold subcontractors accountable and require best crews.

High Performance Windows – Keeps heat in during the winter and out during the summer

Improved and Effective Insulation – Ensures temperatures are even throughout the house, helps use less energy, and increases comfort

Advanced Framing & Smart Construction – Eliminates drafts, moisture, dust, insects, pollen and noise

Energy Efficient Heating and Cooling Equipment – Guarantees enhanced performance, and longer equipment life

Better-Quality Insulated and Air Sealed Ducts – Provides for improved indoor air quality, comfort and efficient duct systems

Radiant Roof Barrier – Protects the home and attic from excessive summer heat and keeps heat in during the winter.

Lighting and Appliances – Higher efficiency lighting & ENERGY STAR qualified products that provide for additional energy savings

Improved Water Efficiency – WaterSense-certified fixtures that provide for water savings without sacrificing performance.

Exceptional Indoor Air Quality – Low VOC paints, carpets and mechanical fresh air intake for improved indoor air quality


The Energy Smart Home Process

The process to certify a home as Energy Smart requires a standardized level of inspection, testing and RESNET oversight as well as access to credible building science consultants (HERS Raters)

There are four main stakeholders in the Energy Smart home build process: Builder, HVAC contractor, Insulator and Home Energy Rater.


Major Steps and Stakeholders

  • Builder or Homebuyer Decide to Build to Higher Performance Standards
  • Builder or Homebuyer Register and Submit a Set of Plans to E2 Technologies
  • Effect Energy performs an Analysis that Includes the HERS Index, Monthly Energy Cost Estimates, System Sizing and UA compliance.
  • HVAC Contractor Designs the System to Manual J, T, S & D criteria
  • Insulator Installs Insulation to RESNET Grade 1 Standards
  • Rater Conducts Visual Insulation and Air Sealing Inspections (Rough-in Inspection)
  • Rater Performs Final Diagnostic Testing (Finish-out Inspection)
  • E2 Technologies Sends Final Certificate, Label and Package to Builder or Homebuyer


How to Work Together

E2 Technoligies’ home performance certificate is generated from the outcome of RESNET’s Home Energy Rating System (HERS). Home energy ratings involve an analysis of a home’s construction plans (as applicable) and onsite inspections. Based on the home’s plans or takeoffs, the Home Energy Rater uses an energy efficiency software package to perform an energy analysis of the home’s design.

Upon completion of the plan analysis, the rater will work with the builder or homeowner to identify the energy efficiency improvements needed to ensure the house will meet predefined certification or performance goals. The rater then conducts onsite inspections, typically including a blower door test (to test the leakiness of the house) and a duct test (to test the leakiness of the duct system). Results of these tests, along with inputs derived from the house plans or takeoffs, are used to generate the HERS Index for the home.

A home energy rating is a recognized tool in the mortgage industry as well as multiple green building programs. Since a rating quantifies the energy performance of a home, the HERS Index provides an easily understandable means to compare the relative energy efficiency of different homes.


The HERS Index

hers-indexThe HERS Index is a scoring system established by the Residential Energy Services Network (RESNET) in which a home built to the specifications of the HERS Reference Home (based on the 2004 International Energy Conservation Code) scores a HERS Index of 100, while a net zero energy home scores a HERS Index of 0. The lower a home’s HERS Index, the more energy efficient it is in comparison to the HERS Reference Home.

Each 1-point decrease in the HERS Index corresponds to a 1% reduction in energy consumption compared to the HERS Reference Home. Thus a home with a HERS Index of 85 is 15% more energy efficient than the HERS Reference Home and a home with a HERS Index of 80 is 20% more energy efficient.


Benefits of Hiring a RESNET Member Rater

Choosing a RESNET rater member means that you are selecting someone you can trust to objectively provide you with a comprehensive analysis of the home’s major energy systems and components.

RESNET rater members are trained and have demonstrated technical proficiency and have committed to maintain and improve their technical proficiency through continuing education.

Members are committed to conducting ratings in accordance with the RESNET Rating Standards of Practice; abiding by the RESNET Rating Code of Ethics, and disclose any financial interest in the home being rated. Through their membership to RESNET, member raters demonstrate their commitment to technical and ethical quality.


Smart Builders – Smart Choices

resnet-builderRESNET Energy Smart Builders are committed to increasing the energy performance of the homes they build. These energy efficient homes are more affordable to maintain, more comfortable and have a higher value compared to regular homes. The efforts of these leading builders benefit consumers, the environment, the local economy and our national security.

Energy Smart Builders are committed to having all of their homes energy rated following RESNET’s stringent standards, and marketing their homes’ HERS Index. The RESNET HERS Index is the industry standard by which a home’s energy efficiency is measured (learn more about the HERS Index). The use of the HERS Index differentiates homes built by RESNET Energy Smart Builders from other homes for sale in the market. Over 1 million homes have been rated on the HERS Index since 1995.

Home builders from across the nation have already been designated as RESNET Energy Smart Builders. View listings:

To be designated by RESNET as an Energy Smart Builder, a builder enters into a Memorandum of Understanding with RESNET to have all of their homes energy rated and to market the homes’ HERS Index. There is no cost to the builder to RESNET to enter into the agreement.
