OSRAM Opto Semiconductor’s new wafer facility in Penang, Pen32, is certified as a Green Building, conforming to a multitude of requirements on design and construction under the GBI (Green Building Index). The new building aligns with OSRAM’s standards for fabrication sites and is one of the first industrial buildings in Malaysia to have been awarded the certification after going through close scrutiny on design and construction.
GBI looks at the efficient use of resources (such as energy, water, and materials) and the reduction of building impact on human health and environment during a building’s lifecycle. It is challenging for an industrial building to meet these criteria but the company has a strong conviction to achieve the task.
“Right from the beginning when we planned to build a new wafer facility here, we wanted it to have minimal impact on its surroundings,” said Dr. Roland Mueller, Managing Director of OSRAM Opto Semiconductors (M) Sdn Bhd. “Not only can we achieve savings in our operations, but also we can show that we are committed for a better future for the people and environment around us.”
Starting with the construction phase, amenities have been made available and accessible to the project workers. Care has been taken not to be the source of pollution during and after construction. All construction materials are acquired locally in line with the GBI requirement while refrigerants and cleaning agents are of non-ozone depleting types. Waste is removed properly on a daily basis and stations are set up to collect materials that can be recycled.
Penang has equatorial climate. To cool down the building and to lower the overall building thermal transfer value to be within GBI acceptable levels, several measures are taken. The use of thermal efficient bricks and low emissivity glass, together with adequate insulation, significantly reduces the overall thermal transfer. Energy usage is optimized through the use of lighting zoning, relevant energy monitoring sub-meters and medium temperature chillers. The pumping systems are fitted with variable speed drives to cater for different usage, thus further reducing energy needs.
Indoor environment quality also forms part of the GBI.
