Zero Energy Buildings

Topic Background

Zero-Energy Building (ZEB) is a concept of combination of minimizing energy consumption via efficient appliances and energy management system and onsite renewable power generation, mainly solar, to bring the net energy consumption of the building to zero. If this technology is applied world-wide, it would cut carbon emissions by 300Mt by 2050. As heating and cooling account for more than one third of energy condition, which is influenced by different climate condition across the globe, the technology for ZEB needs to be tailored taking regional needs into account.

Where we are heading

According to the Energy Technology Perspectives 2012, compiled by the International Energy Agency (IEA), the development and dissemination of heat-insulating technology for buildings is estimated to create CO2 emission reduction potential of approximately 300 million tons worldwide in 2050.
