With this Communication, released in February 2016, the European Commission presents the first strategy to optimise buildings' and industries' heating and cooling in order to tackle the massive use of energy, particularly fossil fuels, in the sector. Heating and cooling accounts for 50% of the energy consumption in the European Union, and renewables account for just 18% of this.

European legislation makes nearly Zero-Energy Buildings (nZEBs) a standard by 2020. The technology is available and proven; however, the large-scale uptake of nZEB construction and renovation remains a challenge. ZEBRA2020 monitored the market uptake of nZEBs across Europe and provided data and knowledge on how to reach the nZEB standard. This information was structured and analysed to derive recommendations. ZEBRA2020 covers 17 European countries and almost 90% of the EU/EEA building stock and population.

Green building is cost-effective

1. Upfront investment in green building makes properties more valuable, with an average expected increase in value of 4 percent. By virtue of lowered maintenance and energy costs the return on investment from green building is rapid: green retrofit projects are generally expected to pay for itself in just seven years. 3

The purpose of the framework is to create a clear and coherent climate policy.

The Green Building Council of Australia with the Property Council of Australia, Australian Institute of Refrigeration, Air Conditioning and Heating (AIRAH), Energy Efficiency Council, Facilities Management Association of Australia, City of Sydney, City of Melbourne and CitySwitch have produced a policy framework addressing the potential opportunities presented by increasing the energy efficiency requirements for mid-tier buildings.

The original policy issued by The Science Council of Japan was in Japanese, and this English article summarises the policy that outlined a roadmap to realize a healthy low-carbon society. The aim of the policy is to build a low carbon footprint and high environmental performance. There are four parts as below: 

(1) Increasing motivation for new, healthy, low-carbon lifestyles and behavioral changes

Cities need to become ‘smarter’ if we are to save the planet. John Dora, editor of a special issue of ICE Engineering Sustainability journal on smart cities, says the ingenuity of civil engineers will be essential for their delivery.
