![]() Compared to other solutions in buildings, the selection of envelope structure and materials is particularly important, given the long lifetime of buildings and the associated cost of the envelope. Good building design, integrating high-performing envelopes, is the most effective way to reduce the thermal needs of buildings and ensure occupants’ thermal comfort. The United Kingdom Department for Energy Security and Net Zero (DESNZ) announced GBP 1.8 billion in 2023 to upgrade the energy efficiency of homes and public buildings through the Social Housing Decarbonisation Fund, Home Upgrade Grant and Public Sector Decarbonisation Scheme.Türkiye, Japan, China, India and Australia updated their buildings regulations, adding more stringent energy efficiency requirements.The European Union’s REPowerEU initiative, one of a wide range of measures for clean energy transition, promotes energy-efficient building retrofits to support rapid reduction of dependence on Russian fossil fuels.The European Union adopted a new revision of the Energy Performance of Buildings Directive (EPBD) in 2023 (pending trilogue approval) that stipulates higher Minimum Energy Performance Standards for existing buildings, timelines to achieve them, and earlier deadlines for buildings to become zero-emissions: for all new public buildings from 2026, and for all new buildings from 2028.The zero-carbon-ready concept includes both operational and embodied emissions.Ĭountries and regions making notable progress to advance on building envelopes include: 1 This also requires 20% of the existing building floor area to be renovated to this level by 2030, with annual energy efficiency renovation rates jumping from less than 1% today to 2.5% by 2030 globally.ġ Zero-carbon-ready-buildings are highly energy-efficient and resilient buildings that either use renewable energy directly, or rely on a source of energy supply that can be fully decarbonised, such as electricity or district energy. To get in step with the Net Zero Emissions by 2050 (NZE) Scenario, all countries need to establish zero-carbon-ready building energy codes for both residential and non-residential buildings by 2030 at the latest, and all new buildings should meet this standard from 2030. Its structure is also important in determining a building’s embodied carbon impact. ![]() More than 110 countries lacked mandatory building energy codes in 2022, meaning that around 2.4 billion square metres of floorspace – the equivalent of Spain’s entire building stock – was built last year without meeting any energy-related performance requirements.īuilding envelope design is critical in defining the service demand for heating and cooling, and to guarantee comfort, indoor environmental quality and safety.
