Abstract [en]

Climate change is an increasingly widely known concept. In the EU the construction sector is responsible for more than a third of the carbon dioxide emissions and 40 % of the total energy use. In Sweden, measures have been taken to prevent this climate change. By 16 targets, three of which can be linked to the construction sector, Sweden will reduce the negative trend. None of the three goals with relation to the construction sector will however be achieved before 2020. One of the methods for changing this is to environmentally certificate more buildings, both existing and new constructions. The construction growth in the EU is around 1 % per year, which means that existing buildings represent a very large share of the construction sector and therefore its carbon footprint. To renovate existing buildings to a more sustainable standard is therefore of great importance.

The aim of the study has been to see how the work with the environmental certification system Miljöbyggnad works with existing buildings and to examine whether it is possible to renovate the landmarked building Jakobsbergsskolan in Kristinehamn to any level within Miljöbyggnad higher than Rated, thus Bronze, Silver or Gold. The goal has been to develop a basis for Kristinehamn municipality that may be included in the process of decision-making for the redevelopment of the building. The foundation should consist of new drawings, documentation of the existing building and to show what measures are required to obtain environmental certification of the over one hundred years old school.

To map the building, site visits have been made, including inspections and measurements of the windows, the garret was inspected to try to figure out how the building is constructed and photographs of the facade were taken to then be able to measure the building. In addition to the site visits, literature on Swedish building history have been studied and an experienced carpenter was consulted to get the best possible knowledge of how the building is constructed. Thereafter, the building was drawn in 3D in the program Revit 2014. Kristinehamn municipality has provided data to many of the indicators, such as radon and legionella. In addition, the building have been energy analyzed in VIP-Energy, the thermal climate has been examined by PPD-index and daylight climate investigated with the VELUX Daylight Visualizer. The building has been rated, whereupon appropriate measures were planned and regraded.

Once all 16 of the indicators in Miljöbyggnad was checked, it turned out that the existing building only reaches the grade Rated and is in great need of refurbishment. The parts that require the greatest action for a higher rating are the buildings climate shell, the ventilation system and to overcome the moisture damage. After measures have been taken for most of the indicators, the building can be certified with a rating of Bronze.

Conclusions that can be drawn is that the building needs to be significantly upgraded and it will require major efforts from Kristinehamn ́s municipality for a certification to be possible. If adequate measures are taken, the building will be certified with a rating Bronze. The study shows however, that it will not be possible to achieve Silver or Gold. A certification of the school, which was built in the late nineteenth century would, from Kristinehamn's municipality, show a great interest in sustainable development. It would also show that it is possible to combine the old, through cultural value, with the new, through an environmental certification.
