Completed in 2014, this project for the fit out of a disused boiler house to provide a one bedroom Passive House has recently been Certified to the Passivhaus Standard, making it Europe’s smallest inhabited Passivhaus.
The house has a heating load of just 10W/m2 annually – the equivalent of burning 16 candles to heat the whole house. This was tricky to achieve as the existing building was single storey and L-shaped, increasing the surface area available for heat loss, and located in Orkney, with negligible levels of solar gain in winter.

Architeco carried out the design, detailing, calculations, and energy modelling for this project.
