In order to bring higher energy-efficiency standards to Columbia housing, the City Council approved an update to building codes. The Environment and Energy Commission deemed an increase in the amount of attic, wall and perimeter foundation insulation as the most important and cost-effective energy changes from the previous code. The code calls for insulation with a higher R-value, which is a measure of thermal resistance. According to the commission, the new insulation will cause an increase in energy bill savings for home owners of about 3.3 percent more than the previous code.
