Wiwynn, a company originating from Taiwan, has its Malaysia Plant set up in Senai Airport City, Johor Bahru. This industrial project features a building designed with green and sustainable features, encompassing a sustainable façade design, energy and water-efficient technology, a comfortable and healthy indoor environment, and an active workspace.
At the core of Wiwynn Malaysia Plant is a commitment to sustainability and self-sufficiency, reflected in the 2,530 kWp Solar PV design. This renewable energy effort can offset 26% of the total energy consumption of the plant’s operation. Besides that, the plant is also designed with recycled water facilities, including a rainwater harvesting system that enables 77% savings in potable water usage. The harvested rainwater will be used for the building’s cooling tower water make-up. In addition, a wastewater recycling system will be installed to reuse air conditioning condensate and greywater from the toilets for irrigation and cooling tower make-up purposes. The wastewater recycling system contributes up to 17%, exceeding the 10% reduction requirement. All sanitary fittings in the development are carefully selected to ensure high water efficiency.
The sustainable initiatives in architectural design include 70mm mass insulation on the façade wall claddings, roof insulation, and Low-e high-performance double-glazing units (DGU) glass windows. These initiatives significantly reduce heat gain into the building, achieving an Overall Thermal Transfer Value (OTTV) of 12 W/m², compared to the Malaysia Standard (MS) base requirement of 50 W/m². This helps lower the power consumption of indoor air-cooling systems. The green features of the building’s energy system include high-efficiency chillers, variable speed driven (VSD) air handling units (AHUs), and fan and pump equipment to run the air conditioning system efficiently. The building is also designed with a KNX lighting control system. This addressable lighting interface system can manage and control light switches or illuminance levels by reading motion and daylight sensors.
The design offers greater flexibility for light switching, making it easier to illuminate only occupied areas to optimise energy savings. Carbon dioxide sensors are installed in the AHUs to provide the minimum necessary fresh air, reducing energy consumption without compromising human comfort. All these passive and active designs contribute to an energy use intensity (EUI) of 530 kWh/m²/year, resulting in a 30% energy saving. Both digital electrical and water meters are linked to the building management system (BMS) for recording and monitoring purposes. A qualified GBI Accredited Commissioning Specialist (CxS) is onboard to ensure that all energy efficiency and indoor air quality standards, among others, are met.
During construction, the building contractors practiced sustainable construction by prioritising reused and recycled-content, and regional building materials during material selection. To ensure occupant’s health and well-being, the building’s interior finishes were selected for their low volatile organic compounds (VOC) content. The contractors achieved a high quality of workmanship in construction, scoring 80 points in the Quality Assessment System in Construction (QLASSIC) system.
The project owner also provides breakout space, with facilities such as table tennis and board games to reduce worker fatigue. The building’s perimeter design, including the façade and windows, provides ample daylighting, ensuring visual comfort for workers while enhancing their connectivity with the outdoor environment. During operation, shufler buses are provided for factory workers to reduce carbon emissions and air pollution. Wiwynn Malaysia Plant is commifled to driving sustainability by instilling sustainable practices and lifestyles in the long run. This project aims to raise awareness about various climate issues and encourages businesses to adopt practices and policies that are more environmentally friendly.
