Renovera och energieffektivisera ett äldre kök : En undersökning om cirkulära material, bevarande och energieffektivisering

Sammanfattning: Buildings today account for 40% of total energy use in Europe. To reduce the development of climate change, it is necessary to reduce energy use in buildings. Sweden is bound by the European Union (EU) to improve energy efficiency in buildings. To reduce emissions and achieve the environmental goals that have been set, the approach to the built environment must be changed, such as using the material that is available. In this way, energy saving, and resource management can be considered as part of the solution to climate change. Reuse of materials can contribute to a circular economy based on extending life cycles and preserving environmental and economic values that are already extracted natural resources. That is, new material does not need to be produced and the used material does not need to be recycled. The energy that is utilized is already present in the existing materials and can thus promote the preservation of cultural-historical values. The work examines a functionalist kitchen in a former desolate house. The survey consists of various qualitative methods in the form of an interview with the owner of the surveyed house, literature studies in the form of previous research and Stockholm City Museum's tips and advice when renovating older kitchens. Measurement drawings of the kitchen in the examined house have been performed in Auto CAD LT as part of the thesis. The purpose of the work is to shed light on circular materials and increase the possibility of making energy-efficient older kitchens more energy-efficient by preserving materials. It is also to increase knowledge of using the materials in the buildings and to investigate what measures the owners have taken during the renovation of the kitchen. The aim of the study is to identify possible prudent energy efficiency measures that can be considered as resources for conservation, use and care for older buildings. The result must then be able to be sold in other similar kitchens, be helpful in decision-making of older kitchens with cultural-historical value and form the basis for future studies. The results show that the owners' renovation was carried out mainly for aesthetic reasons. But also, that the requirement for comfort and practical solutions were important. The owners had thoughts about the impact on the environment but that was not the driving factor during the renovation. The careful renovation carried out in the kitchen was mainly the preserving materials that were reused. The theoretical starting points for conservation and circular economy have both advantages and disadvantages that can be affected by the relationship to renovation. Measurement drawings add to the renovation with clarity about which materials can be preserved so that the kitchen can be reused and adapted to today's comfort requirements.
