Natural Spaces Domes are the most energy efficient domes, and we'll continue to prove it!

 

 

 

 

A Natural Spaces Dome built by Kim and Steve Long near Perry, Iowa (30 miles NW of Des Moines) has been independently rated, energy wise. The local utility has rated The Natural Spaces Dome as an Energy Star 5 Plus, the highest rating.

 

The other rating is called the HERS Index, 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 2006 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.

The Natural Spaces Dome scored a 60 HERS Index which is extremely low. This means that their dome is 40% more efficient than a new conventional home built to meet the requirements of the new 2006 energy code. Kim and Steve are thrilled as one of their main reasons for building our dome in the middle of a cornfield was to achieve a tight, energy efficient home oblivious to the Midwestern prairie winds and snow. The winter of 2006/2007 will be their first and we will report on the heating and cooling costs.
