Anderson Transformer Lecture 2 Housing Type Figure 2.1: !Annual Energy vs. Volume to Surface Area Ratio: Four Housing Types Claim: !The comparison of energy consumption vs. housing types illustrates that the most efficient housing type is the midrise apartment. When using measured energy consumption data of existing mid-rise buildings, the relationship between energy use and building form cannot be easily demonstrated. The operational energy used in Figure 2 is normalized for climate loads and floor area, but it is still difficult to isolate the relationship of building geometry and energy use. The variability of measured data is mostly due to detail differences in the building envelope and occupant behavior. Therefore, we need to increase the scope of research to include large statistical samples and more detail for these buildings to identify which building forms most affect energy use.
