Abstract [en]

Technical characteristics and cultural values affect the possibility of saving energy in the historic building stock. The issue has been addressed and studied in monumental buildings. For the majority of historic buildings, defined in this research as traditional constructions built before 1945 when the building sector became more industrialised, there is still a need for further studies. In order to study a large building stock it is necessary to make generalisations. To break down the stock into a few statistically representative categories is one way of doing that.

The aim of this article is to present the development of a method to categorise a historic building stock with the ability to identify the potential for energy saving and preservation of cultural values. By studying building categories and typical buildings in detail the results can be extrapolated to represent a large building stock.

The method for categorisation is done in three steps: building inventory, categorisation and selection of typical buildings. The inventory is when data on the building stock is gathered and compiled. This is necessary in order to have a sound statistical basis for the following steps of the method. The categorisation is done by dividing the buildings in groups based on their basic characteristics; for example size and number of adjoining walls. A delimitation is done, if necessary, in order to exclude atypical buildings.

Typical buildings from each category are then selected by letting the medium values within the categories decide the characteristics of the typical buildings. Other characteristics such as age, use, construction type etc. can be determined for the typical buildings and motivated statistically based on the data in the inventory.

A case study has been carried out on the historic building stock in the town Visby in Sweden, a UNESCO World Heritage Site. When applying the method for categorisation on the buildings built before 1945 in Visby the results show that 70 % of the buildings’ volume is represented by 87 % of the buildings. The study shows that it is possible to generalise some aspects even in a relatively richly nuanced building stock by letting the basic characteristics constitute the first common denominators in a categorisation.

The result of the categorisation facilitates the identification of representative typical buildings that can be used for energy modelling. The six groups of typical buildings identified in Visby are presented at the end of the article.

This study has been conducted within the multi-disciplinary projects Potential and policies for energy efficiency in Swedish buildings built before 1945, financed by the Swedish Energy Agency and Energy Efficiency for EU Historic Districts, funded by the European Commission under its Seventh Framework Programme.
