This study analyzed how industrialized building retrofitting measures contribute better decision supports for building retrofitting strategy to the energy saving potential from a Swedish building typology approach. Contributions to cost-effectiveness retrofitting from one distinguishing but major type of Swedish building stock in Stockholm, Sweden, one of which case was studied from a life cycle perspective as demonstrations for the introduced renovation alternatives. A basic life cycle costing tool coupled with building energy demand calculation was applied. The study focus on the relative costing impact mainly from retrofitting materials and building energy consumptions, as well as corresponding importance of the cost contribution from four life cycle stages .
The tool analyzes the retrofitting material costs and embodied energy consumption after undergoing proposed retrofitting work packages as regards as the relevant payback time simulation. For the case type of building stock, a retrofitting measure compounds in terms of various energy saving and architectural service refurbishments were introduced, the most costly measures could be the most cost-effectiveness alternatives in different life cycle stages based on the typology of the target building.
Every building is unique and represents its own contexts, the proposed approach addresses getting an efficient general knowledge for the whole retrofitting and future building performance costs by life cycle thinking, aims at finding the similarities in Swedish building stock for providing greater resource-efficient, lower life cycle costing, simpler decision making and higher profitable building retrofitting strategy.
