Typically the sum of all energies consumed by the building (electricity, natural gas, etc.) over a year is converted into a common dimension (e.g., Btu), which is then divided by gross floor area of the building (e.g., Btu\/GSF yr).\u003Cbr \/\u003E\r\n\u003Cbr \/\u003E\r\nBuilding energy performance metrics like EUI provide some meaningful information regarding the normalized rate of consumption of energy resources during a defined period of time (e.g., Btu\/GSF yr). However, they provide no information regarding the effectiveness of the energy used to provide for the functional performance of buildings. Other metrics are needed, such as tenant or occupant responses, occupant or tenant performance, productivity, and economic rates of ROI. To reduce uncertainties, these functional performance metrics must be quantitatively measurable, valid, repeatable, reliable, and accurate.\u003Cbr \/\u003E\r\n\u003Cbr \/\u003E\r\n\u003Cem\u003EThis quick read is from Davor Novosel, the chief technology officer for the National Energy Management Institute Committee (NEMIC), and James E.
