JEC Thailand supplied, installed, and commissioned the E&M systems for Chula Block L, Chulalongkorn University, which included their air-conditioning & ventilation, water supply & fire protection, and electrical & communication systems.

The building is twelve stories tall covering a total area of 51,861m2, with the first five floors serving as a state-of-the-art tutorial centre, and the remaining floors are used as car parks.

Ventilation and Air-Conditioning Systems
For the ventilation and air-conditioning systems JEC has installed three sets of 325 ton chillers with a cooling capacity to serve 134 sets of FCUs and AHUs. On the third and fourth floors, 14 sets of VRV modules and 90 sets of FCUs have a combined cooling capacity of 555 tons. The retail shops have a ventilation system which has eight sets of KEF and KFF, and pressurised fans in the emergency fire stair wells to prevent smoke entering.

Electrical and Communication System
JEC installed the following electrical systems: SF-6 Load Break Switch Gear, two dry-type transformers with a total capacity of 2,000/2800 KVA, a reserve generator with a capacity of 650 KVA, main distribution system (MDB) consisting of three MDB1, MDB2 and EMDB as a backup, two-wire lighting system, and UPS. JEC also installed the communication and security systems which involved the public address, MATV, CCTV, access control, telephone, and PABX systems. Additionally JEC installed the safety systems which involves the fire alarm, and building automation systems (BAS).
