How Building Insulation Choices Alter Local Microclimates and Energy Use
Quick fact
In a dense city, upgrading building insulation can reduce a building's heating and cooling energy by up to 40%, but it can also raise local air temperatures by several degrees because waste heat is trapped between insulated buildings.
Why this is interesting
