40,000 euros more for a single-family home

The government wants to make solar systems compulsory on house roofs and further tighten the insulation regulations. Other areas also show what climate protection means in everyday life – and what it costs.

Nice new roof: If the environment minister has his way, this bare sight will soon no longer exist.

Et are only eight lines in a 30-page document, but they have what it takes to get excited: according to the plans of the federal government, solar modules are to be compulsory in future on all new buildings. Anyone who extensively renovates their roof should also have to install a photovoltaic system. This is what it says in the draft for the “immediate climate protection program 2022”, which is currently being discussed between the ministries. It also stipulates that new houses must save more energy. The so-called Efficiency House 55 would therefore be raised to the new standard for all buildings from 2023. Standard 40 will then apply two years later. A new building should then only consume 40 percent of the primary energy of a reference house.

Corona is no longer the most important issue in politics; instead, climate protection is once again pressing the top priority. The grand coalition agreed in mid-May that Germany should become climate neutral as early as 2045 and not until 2050. But that goal cannot be achieved simply by writing it into law. People have to change their behavior. Politicians want to achieve this both through regulatory law – such as the solar system requirement that is now being discussed – and through the targeted increase in the price of fossil fuels such as oil and gas. But there is resistance from those affected.
