Abstract
The upcoming revision of the Energy Performance of Buildings Directive (EPBD) will require reporting of the whole life-cycle global warming potential (GWP) for new buildings from 2028 at the European level. In the Nordic countries, several frontrunners have already introduced national climate declaration requirements for new buildings. The focus was primarily on embodied emissions from building materials. However, buildings also comprise a wide range of building energy systems (BES) and technical installations, which contribute to the overall impact. Despite their importance, there is currently a lack of research regarding these building components. Therefore, this paper presents greenhouse gas (GHG) emissions of BES and technical... (More)
The upcoming revision of the Energy Performance of Buildings Directive (EPBD) will require reporting of the whole life-cycle global warming potential (GWP) for new buildings from 2028 at the European level. In the Nordic countries, several frontrunners have already introduced national climate declaration requirements for new buildings. The focus was primarily on embodied emissions from building materials. However, buildings also comprise a wide range of building energy systems (BES) and technical installations, which contribute to the overall impact. Despite their importance, there is currently a lack of research regarding these building components. Therefore, this paper presents greenhouse gas (GHG) emissions of BES and technical installations by using GWP-total climate data. The embodied GHG emissions from the production of air handling units (AHU), lighting systems, cables, cable joints/connectors, LED kits, panel radiators, and transformers are presented as minimum, median, mean, and maximum values. The analysis is based on a dataset of 1,622 environmental product declarations (EPDs) collected across the Nordic countries. The dataset is largely composed of products manufactured in Sweden (44%), followed by Norway (22%) and Estonia (19%), with smaller shares from Finland (7%), Denmark (6%), and Lithuania (2%). The mean values can be used by building designers and environmental consultants as generic climate data to support early-stage sustainable building design and to address data gaps where product-specific information is unavailable.
