Sustainable buildings are the only way forward, just ask property developer Humlegården Fastigheter. With three keywords in mind – reusing, recycling and upcycling, Humlegården developed the concept surrounding Greenhouse in Solna Strand. A project focused on refurbishing what is already there and utilising smart lighting control systems to future-proof the building for years to come, and reaching environmental savings of as much as 75 tonnes of carbon dioxide.
