Case study 296 is a ‘stepping stone’ towards our aim of producing an ecologically advanced Passivhaus refurbishment of a Listed London terrace house, combining many health benefits for the occupants with advanced low energy design. Some of the original external walls have been internally insulated; historic windows have been draft proofed with brush seals and secondary glazing; solar thermal hot water heating has been installed and energy-saving passivhaus heat recovery ventilation provides filtered fresh air throughout the building. A mall green roof has also been installed. A primary objective of this project is to demonstrate that a beautiful Listed home can discreetly incorporate an environmental approach that goes some way to address the ecological imperatives of the 21st century.
