The construction industry is currently responsible for a large amount of greenhouse gas emissions that contribute to the enhanced greenhouse effect. In hopes of facilizing a sustainable development, a new law came in force 2022 requiring climate declarations for new construction projects. This requirement means that construction companies around the country must climate calculate for their construction projects. Among these companies is Akademiska hus, a property management company that strives to become a carbon neutral operation. The thesis was conducted in collaboration with Akademiska hus to investigate how the method of climate calculations can be made more effective. The study was conducted through an interview and a case study of two different projects, Solna Campus Office and Retzius Laboratory. The aim was to identify which part of the process that needs to be made more efficient, and then to develop a solution proposal. The calculation tools Prodikt and One Click LCA were then tested to measure the carbon footprint of the projects, and standard value data was developed. The result from the interview study showed that the problem lies in the lack of a clear method for collecting input data, but that the calculation tools Prodikt and One Click LCA can facilitate the streamlining of climate calculations. The results from the case study shows that the carbon footprint for the projects was measured to, internal wall: 7.21 kgCO2e/m2construction, ceiling: 3.23 kgCO2e/m2 material internal floor: 9.58 kgCO2e/m2 material, wall cladding: 14.18 kgCO2e/m2 material, parts of the ventilation system for Solna Campus Office: 1.12 kgCO2e/m2gross floor area, parts of the ventilation system for Retzius Laboratory HG6: 14.4 kgCO2e/m2gross floor area. Furthermore, it is concluded that these values can be used as standard value data for reconstruction projects under 50 MSEK of office and laboratory environments at Akademiska hus. The conclusion was drawn that if standard value data is developed for reconstruction projects under 50 MSEK, the method of climate calculations will be made more effective.
