For a comprehensive renovation of a family house from the New Green Savings (NZÚ) program, it will be possible to borrow up to two million crowns interest-free. "We can already see at this moment that we have over 2,000 applications. Those applications will include window replacement, door replacement, insulation, but also replacement of the energy source," said Environment Minister Igor Červený for the Motorists party in an interview with Czech Radio Plus.
