In Sweden, there is opportunity to implement energy efficiency measures in about one million existing apartments that are likely to be refurbished within the next 20 years. System analyses of installation of energy efficient windows, and increased insulation in attic and in exterior walls for an existing multi-story building showed that the primary energy savings for the measures depend on the energy supply system. Energy efficiency potential was higher with installation of efficient windows than improved attic insulation. Responses of 673 chairpersons of co-operative hosing associations to a mail-in survey in 2010 also showed that greater proportion of respondents perceived that energy efficient windows had advantages over insulation improvements. However, majority had no intention to implement such measures during next 10 years and economic factors guide their decisions. Lack of expertise to assess the benefits of energy efficiency measures was the most cited hindrances to energy efficiency investments.
