Building Energy Efficiency - Policy, learning and technology change

Sammanfattning: Popular Abstract in English Over thirty years of experience shows that energy efficiency is the easiest, fastest, and cheapest strategy to reduce today’s rampant energy use. To enhance energy efficiency, governmental intervention and business strategies are needed. The question of which governmental policies are the most effective to support energy efficiency remains unanswered. Policy learning and policy evaluations take us closer to the answer. This doctoral thesis provides valuable insights into which policies supported energy efficiency in the building sector. The results show that mandatory energy performance standards of buildings, so-called building codes, and technology procurements are key policies for introducing energy efficient building technologies to the market. In addition, voluntary approaches, such as the passive house standard, testing activities and enhanced networking are essential business strategies for the diffusion of these technologies.
