Passive Architecture

Passive houses have an extremely well insulated building envelope that enables low heat losses and thus low heating energy demand.
Passive houses may be built of any materials like steel (above) or massive wall structures (below)

Design
A house has to adapt to varying needs of different users. This demand includes both suitability of a dwelling into desires concerning furnishing and use of the dwelling and a variety of comfort issues. A Passive House’s energy economy makes traditional heating systems obsolete. As radiators are not needed the whole floor surface can be utilized.

A passive house is an extremely energy-efficient residential building with year-round comfortable interior conditions. In a Passive House, energy-efficiency is a route to good indoor conditions. Due to well insulated building envelope and airtight construction the surfaces are warm. There is no risk of cold draft even from window surfaces.

As with traditional housing, a Passive House is suitable for a wide variety of people, and with special consideration can be designed to meet the requirements of special needs groups. Living in a passive house does not require a special life-style, and buildings are not designed for a certain category of people. But it does, like any other house, require an understanding by the occupant regarding it’s operation and maintenance.

Materials
The appearance of a Passive House does not differ from a conventional house. But a Passive House may also have a contemporary look. The concept also allows for experimental and futuristic architecture that can be realized with high energy efficiency and low environmental impacts.

Passive Houses can be built with all the typical building materials for load-bearing frames. The building envelope can compose of wood frames, block or brick structures, and concrete or light-weight concrete structures when adequately insulated. Even modern steel structures can be used building systems in Passive Houses.
