A scaling model shows that that the free temperature offset between inside and outside increases with the size of buildings. Reducing the lossiness in buildings offers three energy savings advantages: (1) reduce the multiplicative term, (2) increase the free—temperature subtractive term, and (3) cater to the degree-day distribution. Thermal storage can be made to transfer sufficient heat of the day into the coolth of the night. The daily passive solar input is modeled by integrating over the change in zenith angle during the day. Passive solar storage is sized to give a 12—hour time constant.
