    Investigation of the energy performance and renovation opportunities in a historic building.: using questionaire and assessment scale for decision making and improving energy performance.2019Självständigt arbete på avancerad nivå (masterexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [en]

    On a global scale it is estimated that the building sector accounts for about 35% of the final energy use. The building sector accounts for nearly 40% of energy demand in European union (EU) and in Sweden too it is almost the same percentage demand. It is also known that more than 40% of the residential buildings in Europé were built before 1960 when the energy performance regulations for buildings were not so strict in view of the climate change objectives.

    Compared to other countries in the EU, Sweden has a large number of listed or historic buildings as almost 15% of multi-family buildings and 27% of all single-family houses in Sweden were built before 1945. However it also stated that research on listed buildings energy efficiency potential and indoor environment is very scarce in Sweden.

    Due to climate change and the need to reduce greenhouse gas emission

    (mainly CO2) associated with reduction in energy use in buildings is very evident. Some buildings are of heritage significance due to their historical, architectural or cultural values. The Swedish standard SS-EN 16883:2017 refers to them as listed or historic buildings. This standard does not presuppose that all historic buildings need energy performance improvements. The use of this standard is not limited to historic building with heritage values however it can also be applied to historic buildings of all ages and types.

    This study presents an assessment of a historic building built around 1945 where both the building owners energy use data and the building tenants or users indoor environment perceptions includes their expectations on daylight needs, illumination, temperature control or heating and ventilation are evaluated by the assessment scale methodology recommended in the Swedish Standard SS-EN 16883:2017.

    The results obtained have been presented on an assessment scale as per SS-EN 16883:2017 also considering the building users perceptions of the indoor work environment. This could be a basis for future decision making for the building owner considering the planned investments on prioritized and feasible energy effective measures. Thus this study is based on quantitative approach. This assessment scale decision making model can be a basis for future builing investigations and investments iii

    plans in building refurbishments leading to improvements in energy performance of this historic building.
