Analysis of the Icelandic Modified Pitched Green Roof

Abstract:

In Iceland appears historically proven construction of the pitched green roof. The material composition and methods of technological implementation create a unique comprehensive bond, which is resistant to frequent changes and fluctuations of the extreme climate conditions. Nowadays, the design of the construction is not being further developed, it does not use modern construction methods, knowledge, materials and also the construction does not meet the requirements of the building legislation in the European Union and in the Czech Republic. The article is an analysis of structural and material design of the original concept of the pitched turf roof originated from Iceland and particularly the theoretical design solution its modernized modification, which is adapted to suit the requirements of the building codes and laws in the European Union and in the Czech Republic. Another discussed problem is the assessment of the impacts of climate phenomena and its effect on the overall stability and behaviour of building physics of the roof structure and the individual layers captures possible utilization of this construction. The grass mats that create the casing of the pitched green roof affect the physical behaviour of the structure, which is discussed on a theoretical basis.
