Beirut, Lebanon

IC Preschool and Middle School

Preschool and Middle School building, which was second LEED Gold certified project in Lebanon as part of the International College campus in Beirut. In terms of environmental design, the new facilities include water-saving fixtures and water-efficient landscaping, materials sourced locally or regionally, and enhanced energy-efficient thermal comfort systems amongst others, integrated into a very dense residential, and commercial urban environment of Beirut.

Description

After completing the new Elementary School as the first LEED Gold building in Lebanon, the preschool and middle school buildings became the second building part of the IC campus to receive the certification. The design includes a series of roof terraces used as green space and play area with a courtyard in the middle. The two limestone and glass classroom buildings are connected underground by a three-level car and bus parking deck, which provides direct and secure access to the buildings. A two-story cultural center with music rooms, a library, and a tree-covered roof terrace link the two buildings above ground.
