Minimal Heating or Cooling

Hempcrete homes require minimal heating / cooling because of the unique combination of hempcrete ’ s very good R Value AND its strong thermal mass performance ( the ability to absorb heat and release it back into the interior space when the temperature drops ).
A straw bale home has a good R value , it has almost zero thermal mass performance ; rammed earth houses have a great thermal mass performance but very low R value .
Hempcrete is unique in having both a high R value AND good thermal Mass performance , meaning that heating / cooling of the home is minimal .
This is good news for the home owner ( comfort and electricity bills ) and the environment ( significant reduction of carbon emissions ).
