Buildings hold great potential for cost-effective energy savings. The IEA estimates that the energy savings potential in this sector in 2009 will be in the range of 20 exajoules (EJ) per year by 2030, which is the same as the current annual electricity consumption of the United States and Japan combined.
Barriers such as split incentives between tenants and landlords, lack of awareness of efficient technologies, absence of qualified "green" technicians and high initial investment costs threaten market-driven energy savings measures.
