For the last 10 years in the world has been actively introducing standards of sustainable construction. They are applied to different types of buildings: residential, office, public ones. They also differ in indicators proofing the achievement of the required energy efficiency level ranging from reducing current resource consumption up to awarding a certain energy-efficiency ranking level.
The ACEEE report illustrates many approaches that can be used in developing a building efficiency program to achieve long-term climate goals, to reduce energy consumption and greenhouse gas emissions.
For example, the Tokyo administration has special subsidy packages to spread the practice of "green" rent (commercial rent which ensures the environmental sustainability of the rented property) which partially cover the owners' cost of refurbishment as the rent terms with the tenant are agreed.
The Dutch Government provides tax preferences to partially offset the cost of energy efficiency measures, green loans for commercial buildings and provide preferential interest rates. New York City has had a Green Buildings Law in place since 2009, which requires annual energy and water supply analysis for buildings over 4,600 square metres.
