Abstract

Embodied Carbon (EC) in buildings is increasingly becoming an important factor in carbon management. There are numerous tools and methods to estimate EC right from the beginning of a construction project. However, each tool has its own pros and cons. One such approach is to estimate EC using Element Unit Rates (EC-EUR) and Element Unit Quantity (EUQ). This is made possible by identifying carbon hotspots in buildings in the first instance and developing EC-EURs for different specifications of the carbon hotspots. Development of elemental EC-EUR benchmarks and its application in the proposed elemental approach for predicting EC is presented in the paper. Carbon hotspots of office buildings were identified using a sample of 28 office buildings in the UK where Substructure, Frame, Upper Floors, External Walls and Services were identified as the carbon hotspots. EC-EUR benchmarks were developed for different specifications of the hotspots by statistically modelling the sample for Frame. However, EC-EURs of the rest of the hotspots were not developed due to lack of specification information. The key outcomes of the research include the carbon hotspots of office buildings leading to the development of an early design stage EC prediction model and the concept of developing EC-EUR benchmarks which are not established at the moment and hence, fill the knowledge gap in the literature.
