Utvärdering av poängkriterier i Svanens miljömärkningav flerbostadshus : Mervärde och ekonomiska aspekter av valbara kriterier

Sammanfattning: Environmental awareness in society is increasing and more resources are focused on sustainable development. This has been demonstrated in the construction industry by the fact that more building developers choose to certify their buildings according to the various environmental systems available on the market. A relatively new eco-label for multi-family buildings is the Nordic Swan ecolabel, which usage has increased since its inception in 2011. This can be explained by the fact that the Swan Ecolabelling system is well adapted for the Swedish construction industry, and that the Nordic Ecolabelling brand is well-known in Scandinavia.   The Nordic Swan ecolabel consist of mandatory and optional criterions. There is a total of 14 optional criterions, where a certain number of points can be achieved. There is a total of 44 points for multi-family buildings, of which 17 must be obtained to achieve a Nordic Swan label. These points can be freely picked out of the 14 optional criterions.   The purpose of the study was to assert which of the 14 criterions that gives the most value and should be invested in. The study was approached by two perspectives; the cost of the respective points and the added value of the criteria based on opinions from interested parties.   To evaluate the cost investment per point, all criteria have been reviewed and information has been gathered through relevant sources of information and comparative items. Calculations have been made based on a cost comparison where prices and possible changes have been evaluated to achieve the optional points. Skanska's project Tullholmsviken in Karlstad has been used as a reference project for certain criteria.   In order to measure the added value of the criterions, an interview study has been conducted where employees from Skanska, property owners and residents in a Swan-labeled multi-family house, have been interviewed.   The result of the calculated cost of each criterion and the measured added value, were compiled in a chart, where an average of the different approaches was weighted for each criterion. The highest weighted criteria on the basis of all parties in question, with the highest value overall, were; water-saving measures and energy-efficient products. These should be achieved in a Nordic Swan project, in order to meet needs and wishes from most perspectives. Renewable energy sources and sound environment were the lowest weighted criterions, because of high cost or low priority.
