New house following Passivhaus principles.

This scheme is for a new 3 bedroom eco house located in the Montpelier area of North Bristol. The design follows Passivhaus principles for reducing energy consumption. The clients came to me with a clear brief; to design a very low energy eco house which would significantly reduce the cost of their heating bills but on a restricted budget. The decision was taken at an early stage to follow Passivhaus principles whereby a combination of very high levels of insulation strategies for airtightness controlled ventilation and heat recovery would allow heated air to stay inside the building for longer. Timber I-joists were used as the primary structural members which would allow the space between to be fully filled with over 300mm thickness of insulation and then clad externally with 100mm woodfibre. Junctions between elements (walls roof floor etc.) were carefully detailed and inspected on site to ensure a continuous airtightness layer.
