This Global Status Report documents the status and trends of key indicators for energy use, emissions, technologies, policies, and investments to track the buildings and construction sector, globally and in key regions. Central findings of this report include:
Buildings play a dominant role in the clean energy transition. Buildings construction and operations accounted for 36% of global final energy use and nearly 40% of energy‐related carbon dioxide (CO2) emissions in 2017.
Global buildings sector energy use continues to grow, but not as quickly as population or floor area. Heating, lighting and household cooking are the most improved building end uses. Continued increases in population and floor area are and will be the principal factors of rising energy demand in buildings.
Buildings and construction sector emissions appear to have levelled off since 2015, although they still represent the largest share of total global energy-related CO2 emissions. A clean energy transition will enable a steady decrease in future emissions.
Global dialogue is supporting progress in developing policies for sustainable buildings. Most countries have submitted nationally determined contributions (NDCs) that relate to buildings and some have improved them; however, many NDCs still lack specific actions.
Countries are continuing to implement and update building energy codes and certification policies. However, most expected future buildings growth is in countries that do not have mandatory energy codes and policies in place today.
Investment in energy efficiency in buildings has slowed. Incremental energy efficiency investment increased by 4.7% in 2017 (3% adjusted for inflation), which is the lowest rate of increase in recent years.
The key conclusions include:
International agreements and initiatives are providing direction.
Buildings sector policies and investments are not improving quickly enough.
Social and economic benefits are at hand and ready for the taking.
Achieving sustainable buildings and construction starts today.
A rapid review on green-rated office buildings, and their operational energy use, found that the conclusions of six studies ranged from the certified buildings performing worse, similarly or much better than the non-certified buildings in terms of energy usage intensity. Two...Read more
Industry misconceptions around high cost and poor market interest in energy efficient homes continue to obstruct the mass adoption of low carbon housing. Josh’s House demonstrates that low carbon housing is accessible and cost effective. The Star Performers series showcases how...Read more
Australia's Chief Scientist Alan Finkel points out, in this interview, the need for Australia to develop better storage systems and reflects on the recent report from ACOLA. California Energy Commissioner Andrew McAllister, also warns Australia to pursue demand side...Read more
Evidence gathered by the International Energy Agency has identified six critical factors to guide policy makers in realising potential savings in both new and existing buildings through the modernisation of building energy codes.
The buildings sector contributes nearly 40% to global energy-related annual GHG emissions (IEA/UNEP, 2018). Final energy demand from buildings is predicted to increase 50% by 2050 compared with 2015 levels under business as usual scenarios due to rapid urbanisation and the doubling of the built surface area.
This publication is an analytical report aiming to support the on-going review/revision of EU climate and energy policy instruments. The first objective of the report is to contribute to making 2016 the year of delivery for EU instruments aiming to reduce buildings' energy consumption and their related GHG emissions.
Energy transition of the EU building stock, from being an energy waster to being highly energy efficient and an energy producer, is a prerequisite for Europe’s carbon neutrality, as well as for meeting Europe’s Sustainable Development Goals (SDGs).
