A large proportion of energy used worldwide is expended in the building sector. From a sustainability point of view, it is clear: to bring about a green society, we have to invest in green buildings. But do investments in green buildings pay off? From a micro per- spective, it may be clear: a house-owner installing a more efficient heating system is making a good investment, as the energy costs saved will pay for the investment and more. But is this also true from a macro perspective? What about investors planning to invest in green buildings directly or indirectly—does that pay off as well? In this edition of Inrate Sustainability Matters, we will give you an answer to this question based on recent studies as well as provide you with some interesting company examples. The publication also features an interview with Mr. Noel Morrin, Senior Vice President Sustainability at Skanska on the current sustainability challenges within the construction sector.
