Abstract [en]

Evaluation of carbon impacts during building design has for too long unilaterally focused on the operational carbon impacts through the application of Energy Efficiency Measures (EEMs), e.g. enhancing the thermal resistance of the building envelope by using additional insulations, Window to Wall Ratio (WWR) etc. Research indicates that there is a need to also include the embodied carbon impacts and optimizing the trade-off between embodied and operational carbon impacts. Multi-objective optimization approaches can be a solution for handling this trade-off. Therefore, a previously developed BIM-based multi-objective optimization approach has been extended to also cover the impact of the carbon footprint. The extended optimization approach was then tested in a case study of a multifamily residential building located in Stockholm to find the optimal design solutions of the embodied versus operational carbon impact trade-off. The results of the case study demonstrate the applicability of the extended approach in handling the trade-off problem and aiding in more environmentally friendly decisions during the design process.
