As the UK faces increasing summer temperatures, many homeowners are turning to the Passivhaus standard for energy-efficient cooling solutions. Marion Baeli's home exemplifies this trend, maintaining a temperature significantly cooler than the outside without air conditioning, thanks to extensive retrofitting over a decade.
The Passivhaus approach focuses on airtight construction and effective insulation, which can reduce energy consumption by up to 90%. While retrofitting can be costly, the upcoming Future Homes Standard aims to raise energy performance requirements for new builds, potentially increasing the adoption of these practices.
