According to the left in the Saxon state parliament, the climate-friendly conversion of buildings must not be done at the expense of the tenants. “Energetic modernization must not increase the rent more than the later savings in heating costs. We want to abolish the modernization levy,” said MP Juliane Nagel on Monday in Dresden, referring to an emergency program of the federal government with measures for a climate-neutral building stock. Apart from vague declarations of intent, there is no concept in Saxony that includes both greater energy efficiency and climate-friendly energy supply.
