Purpose: In this project work, the purpose is to perform an LCA as well as an LCC on two concept preschools, one with a wooden frame and one with a concrete frame. The result from the LCA is going to highlight, which of the building frames have the lowest environmental impact. In addition to the environmental impact, the project work  is going to include indoor climate together with energy use to get a broader view of the building’s overall performance. Method: This project work is in collaboration with Futurum Fastigheter i Örebro AB, where the authors have been instructed to perform an LCA on two concept preschools. One preschool has a wooden frame and the other has a concrete frame. The objective is to find out which of the buildings has the largest environmental footprint. In addition to this, the authors have evaluated an LCC together with an additional value tool. There are many tools to analyze the consequences from an environmental as well as an economic perspective. The report includes an LCA, LCC and an additional value tool. Result: The results show that the impact on CO2e/m2 for Bettorp was lower than Silva. Furthermore, the comparison between both preschools illustrated that Bettorp had lower emissions in all greenhouse categories except for carbon storage. The additional value tool portrays positive values for each preschool, although they differ. Conclusion: With the help of the software "One Click LCA" and "Visualisering och kvantifiering av mervärden vid energieffektivisering i offentlig sektor", the questionnaire has been answered and they all point to the wooden frame having a less environmental impacts along with a lower social cost of coal. The additional value tool was answered with the help of three employees at Futurum Fastigheter i Örebro AB. One of the participants concluded that there was no difference with regard to additional value between the preschools. The other two participants agreed that the preschool with a wooden frame provided a higher additional value compared to the other preschool.
