Energy savings/
CO2 Reduction

To define measurement, reporting, and verification for GHG emissions associated with the operation of buildings types of particular climate regions we calculate the weight of carbon dioxide equivalent emitted per square meter per year (kgCO2e/m2 /year). This is done by the following steps:

Step 1: Calculation of the status quo to determine the baseline of energy consumption in kWh/m2 /year.

Step 2: Calculation of the primary energy consumption of the specific technologies and/or appliances in kWh/m2 /year.

Step 3: For the calculation of the related CO2/m2 /year emissions the energy figures will be multiplied by the CO2 emission factor for the primary energy used. For natural gas the emission factor is 0.0561 KtCO2/TJ (IPCC, 2006) and for coal 0.0946 KtCO2/TJ.

This method for MRV energy use and CO2 emissions in buildings provides the basis for establishing baselines, performance benchmarking, and monitoring building performance improvements. Policy- and decision-makers can use this data for establishing national regulations and to define baselines that can be used to set targets for emission reduction in the building sector.
