This technical methodology provides a method for calculating the operational efficiency of a new building. Operational efficiency seeks to address carbon emissions from the use of energy and water in the operation of buildings, while also improving indoor environmental qualities for occupants.  This technical methodology is intended to support a common measurement approach and consistency for assessing operational efficiency across the sector.
