Palm, Pandanus, sugar cane and Ti leaf bundles were other common covering materials. Consider this, it takes about 40 Ti leaves to cover a square foot. Palm branches with the lower leaves removed have an added advantage when used in construction. The stiff stalks add rigidity to the framework and with the large mass of the palm the surface can be covered quickly and with depth. Grass thatch will last for many years but being an organic material it will eventually decompose and have to be replaced. Grass and leaves are naturally regenerative and a hale like this is a sustainable design.
There are two basic house designs used in old Hawaii a steep roof ‘A’ frame or an ‘A’ frame raised on short walls. Hawaiians had no nails or metal of any kind. Wooden poles were notched and fastened together with appropriate thicknesses of twisted string, twine or rope. Starting at the bottom, overlapping rows of thatch are tied to horizontal purlins, up the walls and over the roof.
Clermont - Ferrand
Clermont - Ferrand is a city and commune of France, in the Auvergne-Rhône-Alpes region. It sits on the plain of Limagne in the Massif Central the chain of volcanoes Chaîne des Puys surround it. According to Köppen climate classification, the climate is characterized as Cfb (Marine West Coast Climate).
Cfb (subtropical highland variety) climates usually occur in the higher middle latitudes on the western sides of continents between the latitudes of 40° and 60°. The subtropical highland variety of the oceanic climate (Cfb) exists in elevated portions of the world that are within either the tropics or subtropics, though it is typically found in mountainous locations in some tropical countries. Despite the latitude, the higher altitudes of these regions mean that the climate tends to share characteristics with oceanic climates, though it also tends to experience noticeably drier weather during the lower-sun "winter" season. In locations outside the tropics, other than the drying trend in the winter, subtropical highland climates tend to be essentially identical to an oceanic climate, with mild summers and noticeably cooler winters, plus, in some instances, some snowfall. In the tropics, a subtropical highland climate tends to feature spring-like weather year-round, where temperatures remain relatively constant and snowfall is seldom seen.
