This Global Status Report by the Global Alliance for Buildings and Construction (GABC) reconfirms the significance of building energy consumption as a contributor to global greenhouse gas (GHG) emissions. It also shows that efforts to decarbonise the building sector through the implementation of comprehensive policy frameworks and the deployment of existing energy efficient technologies and building design approaches can deliver positive economic, social, health and environmental benefits.
According to the report, the effective implementation of building energy policies, technologies and efficient building designs and renovations relies on reliability and accessible data as a basis for decision-making, technical-professional capability and increasing the level of awareness and demand for energy efficient and low-carbon buildings.
The report concludes that some progress is being made; however, the pace and scale of actions does not match neither the need nor the urgency of the challenge. To realise the potential of the sector requires policy, technology and finance measures which will accelerate efforts in all regions.
Key priorities identified in the draft GABC roadmap include:
1. Urban planning policies for energy efficiency
2. Improve the performance of existing buildings
3. Achieve net-zero operating emissions
4. Improve energy management of all buildings
5. Decarbonise energy
6. Reduce embodied energy and emissions
7. Reduce energy demand from appliances
8. Upgrade adaptation

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
In response to feedback, high-income households can reduce their energy use to a larger degree than low-income households (17% vs 3% reduction). This and other insights were gained by two rapid reviews into research, both Australian and International, on digital services and...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
This chapter aims to update the knowledge on the building sector since the Intergovernmental Panel on Climate Change (IPCC) Fourth Assessment Report (AR4) from a mitigation perspective. Buildings and activities in buildings are responsible for a significant share of GHG emissions, but they are also the key to mitigation strategies.
This report illustrates that adjusting building standards to impact the cities' environment, economy and etc. The standards mentioned here starts from the construction process until the entire lifecycle of the building in Chinese cities. Research support that buildings that are both energy efficient and supplied by clean energy is fundamental in securing a climate-safe future.
Buildings are key to low-carbon development everywhere, and many countries have introduced building energy codes to improve energy efficiency in buildings. Yet, building energy codes can only deliver results when the codes are implemented. For this reason, studies of building energy codes need to consider implementation of building energy codes in a consistent and comprehensive way.
The building sector has been identified as a sector with large potential for delivering energy savings and mitigation of GHG emissions. Yet it has been unclear what the specific role of building energy efficiency codes play in achieving these savings.
