Miljöklassningssystem
Skillnader mellan Miljöklassad Byggnad och LEED samt dess påverkan på fastighetsvärdet
A uniform environmental rating system for green buildings is demanded in today's society, where the requirements of the energy consumption for real estate are increasing. There are several different systems around the world used to rate buildings, all with different assessment criteria and starting points, which make it difficult to compare environmental rated buildings with each other.The purpose of this paper is to acquire knowledge about the differences between the Swedish environmental rating system Miljöklassad Byggnad and the American LEED, to discover which system is most advantageous. We also examine whether environmental rating affect the value of a property.Miljöklassad Byggnad is relatively simple structured, which makes it possible for private individuals to rate their property. LEED is better structured on the other hand in the case of environmental classification of commercial properties, because there are manuals for among others hospitals, schools and retail. The rating system for Miljöklassad Byggnad is good since the system seeks to fix the number of errors and deficiencies as soon as possible. LEED is an international environmental rating system which is favorable to international investors. However, the fees for are LEED higher than that of Miljöklassad Byggnad.Green buildings are an environmental opportunity and are important for the economy. Lind & Lundström (2009), Eichholtz et al. (2009) and Åslund (2009) show that the rental income and the selling price for green buildings are on the increase, compared to traditional real estate. This is because the rental guests ask for and payment of green buildings is greater than for traditional, because an environmental rated property has lower operating and maintenance costs due to lower energy costs. It is difficult to say to what extent the values of the properties will be affected by environmental classification where no accepted valuation method is available for the environmental rated property. We think green lease are the future ? contracts where both tenants and property owners are working together to reduce the building's energy consumption.
