Framework to Model Building Carbon Emissions

As part of the DynamicRenowave project on life cycle assessment and energy simulation of building renovation strategies activities, a new modeling framework has been created. Two objectives were set first to define a common modeling approach to assess operational GHG emissions in buildings. Secondly, define a standard life cycle assessment approach to assess the embodied GHG emissions allowing to compare different new and existing buildings and energy conservation measures worldwide. Several meetings and discussions took place between January and June 2024 to identify a systematic methodology for assessing the overheating risk in buildings and enable the comparative evaluation of carbon emissions of buildings and building services. The authors succeeded in identifying two major approaches based on international standards and in line with IPCC reports. The framework comprises ten decision modules that allow coupling the embodied, operational and end-of-life emissions calculations based on international standards and materials databases.
