SIPs and the HERS Index - Dare To Go Low

Posted by Roberta Bartel on July 18, 2018

The Path to Net Zero Energy Homes

According to the Structural Insulated Panel Association, there were over 2,000 homes in the United States receiving a HERS Index of 40 or less in 2017. Colorado leads the way with 502 homes below 40.  How low can you go with SIPs construction?

The Enercept Home pictured here and located in Divide, CO has a HERS Index of 19. home with low HERS Index 

While this is well under the HERS 40 threshold, it still has a ways to go before reaching net-zero standards.

Zero Energy cites 11 integrated steps to achieve affordable Zero Energy Home Construction:

  1. Start with Smart Design
  2. Use Energy Modeling
  3. Super-Seal the Building Envelope
  4. Super-Insulate the Building Envelope
  5. Heat Water Wisely
  6. Use Highly Insulated Windows and Doors
  7. Use the Sun for Solar Tempering
  8. Select an Energy-Efficient Heating and Cooling System
  9. Install Energy Efficient Lighting
  10.  Select Energy Efficient Appliances and Electronics
  11. Use the Sun for Renewable Energy

As you can see, building with super energy-efficient structural insulated panels can play a big role in the building envelope. The superior insulating quality of the solid foam core also creates an air tight  envelope with little or no thermal bridging. When combined with the other measures listed above, it is easy to imagine how easy it would be to go go Net Zero.

In this video Ted Clifton explains building to Net Zero Energy very well:
