Abstract [en]

An environmental certificate gives information about the characteristics of the building today, but does not, as the current study shows, guarantee future performance. The question investigated in this study is if there are any demands at all on a newly constructed and certified building to provide any form of information that shows that the building actually perform according to the promises of the certificate. If there is, then which certificate does have these criteria and how common is it? This report is an attempt to compare popular environmental certificates for newly constructed buildings, but from the perspective of their demand of follow-ups. From the point of view of a property investor and a valuation professional, it should be of interest to identify measurable parameters that could provide historical performance data on a building. Also from an environmental perspective actual long term performance should be most important. In the paper we formulate three conditions that a long term credible environmental rating system should fulfill: any certificate should only be preliminary until it has been verified by actual performance metrics, continuous monitoring should be done and it should be mandatory to re-evaluate the building every fifth year according to updated versions of the rating system in question

Abstract [en]

The trend that started with Green Building has moved on into Sustainable Building. But how do we know that something is really sustainable? This project started out with the intention to find a small set of performance indicators for commercial buildings, which could be continuously measured and monitored over time, which would give a good indication of the level of sustainability of the building and as such, and be presented as an additional part in a valuation. Since it has been shown several times over by now that properties that can prove they are sustainable generate a higher market price, these performance indicators would be interesting from the perspective of a valuation professional. In order to find these parameters, the project began with three of the international environmental certification systems and one Swedish system, to study which parameters are considered important in these systems. Following that study, surveys and interviews within the real estate business in Sweden provided an insight into how performance is measured today. Lastly, by combining those studies with a review of the sustainability information considered important by the Royal Institute of Chartered Surveyors (RICS) from a valuation professional’s point of view and an updated literature review, a simple set of indicators could indeed be identified. There is however, still a problem with defining their actual impact on market price. Other authors have come to the conclusion that although sustainability can be measured to some extent, incorporating that information into valuation of the property in a statistical secure way is not yet possible. We need to increase our knowledge about the performance of our built environment and the presented key performance indicators in this thesis would help us do just that. We can also see that real estate owners in many cases already gather much information about their buildings, but they lack the incentives to share that data with others.
