It is widely accepted that current levels of energy consumption are unsustainable, and half of energy consumption is related to houses. Passive houses, zero or plus energy buildings should therefore be an important corner stone in any sustainable energy strategy. They combine lowest possible energy consumption, as well as providing high levels of comfort and favourable long term economic value. The European Union wants passive houses to be the building standard by 2020.

This comprehensive guide introduces readers to the basic concepts of passive houses. It provides detailed examples of passive houses in different geographical areas and climates. It compares the advantages of different solutions for well-insulated and air-tight construction and details suitable ventilation systems. The economic and ecological benefits of this new type of building are explained and demonstrated.

While the passive house principle is also applicable to the refurbishment of old houses, this book will concentrate on the development of new buildings. Overall the book provides an accessible, up-to-date text suitable for architects, building owners and students.
