Climate-friendly properties
…investments in the insulation of buildings older than 30 years usually pay off quickly in financial terms?
For the majority of energy renovations, a combination of improved insulation and a switch to a CO2-neutral heating system is the optimal approach – from both an environmental and financial perspective.
…a solar heating system covering around 20 m2 of a roof surface will meet 80 percent of the annual electricity requirements of a family of four living in an average single-family home?
And just 4 m2 of solar collectors in combination with a water storage tank will meet more than half the annual hot-water needs of a family of four.
