Abstract
In Sweden, as well as in Europe, buildings are estimated to consume 40 % of the total energy use. Moreover, one third of the European building stock consists of buildings with some sort of distinguable cultural or historic significance, and it follows logically that a considerable percentage of Sweden’s and Europe’s total energy is consumed by this category of buildings –historic buildings. Especially when considering that historic buildings typically have inferior energy performance than other buildings. The challenge to improve the energy performance in historic buildings while also taking heritage values into consideration is undertaken within the scope of this master’s thesis. The European standard “Conservation of cultural heritage –Guidelines for improving the energy performance of historic buildings” (SS-EN 16883:2017) is partially applied to a case-building in order to approach the challenge methodically.The energy performance of a building and proposed refurbishment measures is evaluated through the use of computer-generated building energy models. Three different scenarios with sets of refurbishment measures have been simulated; (1) light impact, (2) moderate impact and(3) heavy impact on heritage values. Categorization of the refurbishment measures have been accomplished by using an objectivistic approach based on contemporary conservation theories and definitions. The theoretical framework is primarily based on conservation practices laid out by the Burra Charter.The light refurbishment package would reduce the heating energy use by almost 11 % while having little to no impact on the building’s heritage values. The moderate package would reduce the heating energy use by 34,5 % without having a major impact on the building’s heritage values. The most invasive refurbishment package would, the heavy refurbishment package,would reduce the heating energy use by almost 40 %. This significant energy use reduction would not come without its drawbacks. This package of measures would in fact alter some of the expressed character defining elements of the building.Improving the energy efficiency of built heritage is a challenge, especially when trying to assess the impact it might have on its heritage values. This master’s thesis can provide some insight into the act of balancing energy improvement measures and cultural heritage values against one another, especially for buildings that lack formal protection in the form of legislative directives or policies.
