The project site includes the factory, a warehouse, a canteen and some auxiliary areas. The main products manufactured by the factory are sportswear intended for export.

Garment Factory 3 has integrated a wide range of energy and water saving features. Passive Design techniques were applied, including limiting west and east orientation, reducing window-to-wall ratio (only 13.29% of WWR on east/west facades) and maximizing natural ventilation for the canteen building. Low-E glazing was installed for office area with SHGC = 0.55 and corridor was used as buffer between glazed façade and office rooms to limit solar radiation through the building envelope.

In term of materials and resources, 24.27% of all building materials are recycled materials and 100% of non-structural walls are made of non-baked materials (concrete blocks).

To ensure health and comfort for the employees, all manufacturing areas are provided fresh air from exhaust fans used as part of the evaporative cooling system. Natural ventilation provides sufficient fresh air for canteen, guardhouse, medicine room, etc. Added to this, 100% paints, coatings, adhesives, sealants, floorings, composite wood used are low-VOC content products. 100% of occupied area of the factory has views to the outside and 96% of occupied area has appropriate daylight, which increase occupant comfort while reducing the energy required for lighting.
