Buildings account for approximately 40 percent of global energy consumption . Smart technology based on IoT can drastically improve the energy efficiency of buildings. Norway is a leader when it comes to the use of this technology on a large scale. For example, Statsbygg – which is responsible for all state-funded construction projects – invests a lot here. This has opened up the market and made similar solutions more accessible to private actors. Norway is also making great progress through strict requirements for energy use in new buildings. In the private sector , the Powerhouse alliance develops energy-positive buildings that generate more energy than they consume throughout their lifetime. Powerhouse and similar Norwegian firms have attracted considerable international attention as spearheads for energy-positive architecture.
