Power sector decarbonisation and enhanced energy efficiency in buildings have helped to stabilise the influences of population and floor area growth on buildings sector emissions.

IEA’s new Efficient World Scenario
The world is missing opportunities to improve energy efficiency and policy is not delivering the full potential gains that are available with current technology.
• What is possible with greater efforts on energy efficiency?
• The IEA’s new Efficient World Scenario answers the question:
What would happen by 2040 if countries realised all the economically viable energy efficiency potential that is available today?

There is significant cost-effective savings potential in every sector
Only one third of the cost-effective potential cumulative energy savings in the Efficient World Scenario are realised in current policies and NDC commitments (New Policies Scenario).

Markets are not keeping up with energy efficiency potential
The average efficiency of air conditioners sold today is less than half of what is typically available on shelves – and one third of best available technology.

Access to cooling is a critical issue in some of the hottest places
There are around 2.8 billion people living in places where it is hot every single day. Only 8% of them have an air conditioner today.

Efficient World Scenario: Buildings could be 40% more efficient
What is possible by 2040? Key policy actions
• Building space could increase by 60% for no additional energy use.
• Space heating, space cooling and water heating offer 60% of savings.
• Comprehensive efficiency regulations, targeting both new and existing building stock and appliances.
• Incentives to encourage consumers to adopt high efficiency appliances and undertake deep energy retrofits.
• Improved quality and availability of energy performance information and tools.

To achieve the Efficient World Scenario, cost effective incremental investment would need to increase to over USD 200 billion in the coming years and to over 300 billion out to 2040.

Energy as a share of total household expenditure is rising, but it is less thanks to efficiency. To 2040, households can avoid over USD 550 billion in the Efficient World Scenario.
