Valley Green

Valley Green Residence is characterised by its unique site. Th complex is situated in a calm region close to the city, amidst the orange garden on the road that links Mkales to ESIB University. It is composed of four sections: Blocks A, B, C and D with a total of 210 studios and suites. It includes also a health club, roof garden, wide lobby area with a coffee shop, and a swimming pool.

Description

The target of the project is to provide Valley Green with total independence from the grid and diesel generator. Therefore, the owner seeks to implement a PV system and a centralized solar thermal plant in the available space. The rooms' standard electrical loads are used by an independent AC, electric heater, television, refrigerator, and three to five lamps.
