IN THE PAST DECADE, green buildings have undergone dramatic development in Stockholm – and indeed throughout Sweden. Construction materials and technologies have developed quickly, and from an investor perspective green building has gone from being an almost unknown concept among developers and investors to being something that is increasingly seen as a necessity. To produce buildings that are not classified in some way as “green” is not an option in Stockholm’s current real estate market. This is a process that is almost completely driven by the market: buildings are built green primarily because it is profitable to build them green, not because the government demands or subsidizes them.
