History[ edit ] The essential concept of the double-skin facade was first explored and tested by the Swiss-French architect Le Corbusier in the early 20th century.

American engineers studying the system in informed Le Corbusier that it would use much more energy than a conventional air system, but Harvey Bryan later concluded Le Corbusier's idea had merit if it included solar heating.

This house included "an elaborate double envelope" with a 2-foot-deep air space conditioned by a separate system from the house itself.

The use of a double skin is evident in construction. Both of these buildings achieve great environmental credentials for their size, with the benefits of a double skin key to this. The Gherkin features triangular windows on the outer skin which skelter up the skyscraper. These windows open according to weather and building data, allowing more or less air to cross flow through the building for ventilation.

Technical Details[ edit ] The cavity between the two skins may be either naturally or mechanically ventilated.

Aging and Thermal Regulation

In cool climates the solar gain within the cavity may be circulated to the occupied space to offset heating requirements, while in hot climates the cavity may be vented out of the building to mitigate solar gain and decrease the cooling load.

In each case the assumption is that a higher insulative value may be achieved by using this glazing configuration versus a conventional glazing configuration. Recent studies showed that the energy performance of a building connected to a double-skin facade can be improved both in the cold and the warm season or in cold and warm climates by optimizing the ventilation strategy of the facade.

The cavity results in a decrease in usable floor space, and depending on the strategy for ventilating the cavity, it may have problems with condensation, becoming soiled or introducing outside noise. The construction of a second skin may also present a significant increase in materials and design costs.

Building energy modelling of double-skin facades is inherently more difficult because of varying heat transfer properties within the cavity, making the modeling of energy performance and the prediction of savings debatable. The literature survey covers a brief description of the concept, history and common double-skin facade types and classifications.

A technical description including construction parameters, facade opening principles and choice of panes and shading devices is also given.

The possibilities and limitations of the system are described and the advantages and disadvantages are presented. Daylight simulations control strategies are also discussed.
