New Morton Home Exceeds Energy Efficiency Standards

An energy analysis was performed on a new home built by Morton Buildings in Iowa.   Due to our commitment to building energy efficient homes that result in cost savings and increased comfort for owners, this home received a HERS Index of 52!  A score of 52 out of 100 means that this home is approximately 50% more energy efficient than a standard home.

During and after construction, onsite inspections and performance testing was conducted to generate a High Efficiency Rating System (HERS) Index.  Energy characteristics such as insulation, window efficiency, heating and cooling efficiency, and solar orientation of the home were measured, resulting in a point score between 1 and 100.  The lower a home’s HERS Index, the more energy efficient it is in comparison to the HERS Reference Home, whose energy features are based on a home built to recent code standards, and which has an index of 100.  For example, a HERS Index of 80 means the home is projected to be 20% more energy efficient than the HERS Reference home.

This home was inspected by a RESNET Certified Home Energy Rating company that issued the Rater Seal of Quality to us because of meeting higher standards in ethics and quality.  So why are Morton buildings generally more energy efficient that our competitors?  Compared to buildings with concrete-block, stud-wall, or steel framing, post-frame buildings can be better insulated.  Characteristics of a properly insulated post-frame structure that will provide optimal energy efficiency include: wood framing that is an insulator, not a conductor; insulation that fills the cavity from column to column and is continuous from grade to ceiling; an air barrier; vapor retarder; deep truss heel; and a well-ventilated attic.  You can see an example in the following home interior photo.
