Baakline, Lebanon

EcoBkerzay

The project is the new construction of a village around a pottery workshop, including houses, kitchen, restaurant, pool, hammam, and other facilities. It obtained a 'Very Good' BREEAM rating.

Description

The EcoBkerzay project reflects the local natural and cultural environment using the principles of vernacular architecture, sustainable design, and endemic design styles. It is a newly built village that grows organically around a pottery workshop and nests itself within the natural setting of a mountainside forest near Baakline in the Chouf area. Bio-climatic design and energy efficiency were achieved through carefully studied windows positioning and proper orientation to allow for cross-ventilation and shading. Except for the very hot mid-summer days, the project relies exclusively on natural ventilation and ceiling fans for cooling. Space heating is achieved through wood trims harvested from the Bkerzay forest and burned in wood stoves. LED & lighting zoning was implemented to reduce the energy load. Solar water heating provides hot water to all lodges, restaurants, workshops, and service areas. To further reduce energy consumption, the project relies on the use of a steam generator to heat the Turkish Bath (Hammam). The project also includes a large array of PV.
