London’s first Passivehaus has a heavily insulated shell made from prefabricated European larch timber. The term Passivehaus refers to an advanced low-energy construction standard that ensures homes are cool in the summer, warm during the winter, and well ventilated with perfect air humidity levels. As a result, the energy-efficient home maintains a high level of indoor air quality while consuming much less energy than other south-facing terraced houses in the area.
The south and west-facing sides of the house feature triple-glazed windows that create bright, airy interior spaces. Retractable external venetian blinds with automatic solar controls adjust sun exposure while allowing the home to take advantage of cool breezes during hot summer days in the British capital. A highly efficient heat recovery ventilation system is up to ten times more efficient than standard systems, and the interior features non-toxic materials to maintain exceptional air quality.
Water for drinking and bathing gets filtered before it reaches the taps, and an external solar thermal panel provides hot water for the home. The house’s lush outdoor spaces foster biodiversity, while a hidden rainwater-harvesting tank under the garden provides enough water for the sweet wildflower meadow, green roof and ivy-covered stone walls.
