Miljöstyrning i Riksbyggens ombyggnadsprocess med hjälp av Miljöbyggnad
How the renovation of the vast Swedish existing building stock with renovation needs will be performed is considered as decisive in order to achieve the target set by the Swedish government of reducing the energy use by 20 percent by 2020. Consequently, the challenge of the building sector consists in reducing the energy use in the existing building stock but at the same time ensuring that the indoor environmental quality is improved and the cultural values are maintained.So far, there have been a few renovation projects which strongly have reduced the energy use and at the same time have taken into account the environmental aspects and the cultural values. The main reasons are that there have been few incentives and a lack of routines in order to steer efficiently a ?sustainable renovation?.The participants in a Nordic project on sustainable renovation thought that it would be a strong advantage to link the concept of sustainable renovation to the Miljöbyggnad certification system. Indeed it is trusted by the Swedish building and construction sectors and can provide sustainability targets in order to steer renovation processes.The objective of the master thesis is to show how the Miljöbyggnad certification system could be integrated in practice in the renovation process of Riksbyggen, an organization which administers housing associations (Bostadsrättsföreningar) and build houses. The method used consists in interviewing different employees who work with renovation and studying the management system of Riksbyggen in order to be able to suggest appropriate steps in their process which enable the integration of the Miljöbyggnad certification system. These steps were discussed within Riksbyggen and with researchers. Finally, the master thesis results in a procedure which step by step describes how the Miljöbyggnad certification system could be integrated in the early stages of the current renovation process of Riksbyggen. The proposal focuses on the early stages and is composed of different steps including carrying out a survey in order to investigate how the residents perceive their indoor environment and selecting targets for the project. The master thesis appreciates the extra time and the extra competences which would be required by such integration. Moreover, the report indicates how Riksbyggen could work further in order to apply in practice these steps and suggests how the Miljöbyggnad certification system could be integrated in the other stages.As opposed to new production, where the certification in itself is often the main driving force for using the Miljöbyggnad certification system, the official certification after a renovation is optional. The proposal focuses rather on supporting the environmental management during a renovation project thanks to the Miljöbyggnad certification system. The main advantages which appear are that the certification gives a framework in order to steer the whole renovation process and that it provides a good support in order to assess an existing building.Nevertheless, the master thesis shows that there are also some difficulties in order to integrate the certification. Therefore, the report indicates how these difficulties could be overcome and in which direction the Miljöbyggnad certification system could be developed further in order to meet the needs of the housing companies. Indeed, it could be difficult to select a package of renovation measures which aims to reach a better rating according to the certification because it sometimes might not be reasonable. However, it is possible to plan the renovation project in order to improve the rating for the three following categories: energy, indoor environment and materials or for some indicators. Moreover, the survey which investigates how the residents perceive their indoor environment should become an important part of the process and the results of the survey could be used in order to communicate about successful renovation projects.
