The transition to a Net Zero society requires all sectors to reduce their greenhouse gas/carbon emissions. The buildings sector accounts for approximately 40% of global greenhouse gas emissions. Carbon emissions from buildings arise from 2 distinct categories – the embodied carbon associated with construction materials and equipment; and carbon emissions associated with building operational energy use.

Traditionally, building decarbonisation has focused primarily on the operational energy use. But as we transition to enable Net Zero and energy grids to decarbonise, our building designs and construction must now start to focus on their embodied carbon contribution to global emissions. Globally, this is an emerging area of focus. Reporting of the embodied carbon of buildings is now mandatory in many regions and will come into force in Ireland by 2027 as part of Ireland’s response to the EU Energy Performance of Buildings Directive.

An overview of what the whole life carbon assessment is and how to do it will be provided. The webinar will be of interest to engineers and others involved in the design and construction of buildings across Europe.

Stephen is working on a Sustainable Energy Authority of Ireland (SEAI) funded project to develop a national methodology for Whole Life Carbon assessments of buildings in anticipation of future changes in legislation as a result of the update to the EU Energy Performance of Buildings Directive. The methodology is already being tested on multiple live projects to create a group of uniformly assessed buildings to create the baseline for typical building practices in Ireland today.
