Roof Design

The roof is the top cover of a building that protects the inside of the building from rain or snow. The shape of the roof there is a flat and there is a slant, although flat should be thought to drain the water to fall. Materials for the roof vary, among them: genting (ceramic, concrete), corrugated zinc, asbestos, and cast cement. Adapula roof tiles are very lightweight metal, durable, anti-rust and earthquake resistant.

Several types of plants produce traditional roofing materials. The roof of shingle, one of which is made of ironwood aka iron wood that is clipped thinly. Also the leaves of several types of palms and reeds are often strung together for use as a roof. Among them from the leaves of rumbia, coconut, enau and nipah.

Good home construction should pay attention to energy efficiency. Construction of energy efficient homes in tropical Indonesia is not as complicated as home construction in subtropical countries, as there is no extreme seasonal change. Energy requirements for lighting, insulation, ventilation, air conditioning, and others are not as big as homes in countries with four seasons. Energy efficiency can be maximized by using natural daylight lighting, proper lighting layout, energy-efficient lighting, ventilation and wall insulation, non-heat-absorbing roofing, and the use of energy-efficient electrical appliances.

In the design of energy-efficient homes, including all environmentally-friendly building designs, by minimizing the use of non-renewable energy and optimizing the utilization of natural energy. The limitation of natural resources makes the construction of energy efficient homes become increasingly relevant from now on.
