Buildings account for 36% of EU greenhouse gas emissions. Before the June election, the European Parliament passed amendments to the Energy Efficiency of Buildings Directive (EPBD) on the 12th, hoping to further reduce building carbon emissions. The new regulations require that new buildings must achieve zero carbon emissions from 2030, while new buildings used or owned by public institutions must meet the standard in advance by 2028. The bill also includes regulations for energy-saving renovation of old buildings, reduction of gas boilers, and installation of solar photovoltaics. This important bill on building energy efficiency only has one step left before the EU Council can complete the legislation. However, amid the chaos before the parliamentary election, foreign media said there are still variables. The Building Energy Efficiency Directive was first proposed in 2002 and is an important regulation leading European building energy conservation. According to the European Commission, buildings account for 36% of total EU greenhouse gas emissions and 40% of energy consumption. At the end of 2021, the executive committee proposed amendments to further reduce building carbon emissions. On the 12th, the European Parliament passed an amendment by a vote of 370 to 199, requiring all new buildings to achieve zero carbon emissions from 2030, and new buildings used or owned by public institutions must meet the standard by 2028. EU regulatory member states must formulate policies to reduce energy consumption in residential buildings. The goal is to reduce primary energy by 16% in 2030 and by 20~22% in 2035. The new directive also requires that public and non-residential buildings of a certain size and all new residences be equipped with solar photovoltaics from 2030. Renovation of old buildings involves complex resources
