The CPF Center of Engineering Excellence in Nong Chok, Bangkok, transforms a 30-year-old hatchery into a cutting-edge, net-zero innovation hub for CPF (Thailand). Embracing passive design strategies—optimal orientation, natural ventilation, solar shading, and rooftop photovoltaics—the renovation achieves high energy efficiency. Interiors incorporate furniture and finishes made from CP Group’s recycled plastic waste, reinforcing a sustainable, circular design vision. The architecture harmonizes with its surroundings through contextual integration, biophilic links, and a clean geometric form.
