There has been an EU decision for about 2 weeks that all new buildings from 2021 must meet today's passive house standard. Quote:
Europe's builders must prepare for strict efficiency regulations. From 2021, all new buildings must be constructed fully insulated. The EU bodies agreed on a corresponding law. Buildings, alongside transportation, are among the main emitters of climate-damaging greenhouse gases. Private houses, restaurants, or offices are to be built in the future so that they produce as much energy as they consume. For the first time, industrialized countries are issuing ambitious regulations for buildings with the European Union. Green Party MEP Claude Turmes called the agreement a "breakthrough." Nowhere else in the world are there such building standards, he said after the negotiations. The negotiators of the EU Parliament, the EU Commission, and the Council of Ministers in Brussels had struggled for many months over the requirements. After the now achieved agreement, which still requires formal approval by Parliament and the Council, new buildings are to be equipped with energy-saving modules such as thermal insulation, solar systems, or energy-saving lamps so that their energy consumption amounts to only one tenth of the previous. The regulations apply to private houses from December 31, 2020. New public buildings must already comply with the regulations by the end of 2018.
I am curious how the "massive" builders want to solve this, 17.5 cm exterior walls with 30 cm Styrofoam? In 20 years, the stone house sellers of used properties will lament the resale value.
