Bakich, Lebanon

Le Plateau de Bakich

The project is a brand new single wooden frame house, located in Bakich Metn. The structure will have an area of 270 m2 and contains all the conventional home appliances.

Description

The house will be made of prefabricated wood with insulation material. The blocks will lead to a highly efficient envelope with a small U-value, thus decreasing heating and cooling loads. The slopped roof will be used to install a PV system to reduce energy dependence on EDL and generator subscription.

Specification
The wood structure has been selected to reduce the annual energy bills for cooling and heating. According to HAP simulations the heating load will be reduced from 24.6 to 9.5 kW (61%) and the cooling load will decrease from 20.9 to 16.3 kW (22%). These reduction will be equivalent to cost savings of 13,517 $/year .
