LYSAGHT^® KLIP-LOK^® 406

Multi-Award-Winning Building at National University of Singapore
The National University of Singapore’s (NUS) School of Design and Environment 4 (SDE4), which is six-stories high and spans 8,588 square metres, is the first net-zero energy building in Singapore and also the first in Southeast Asia to be awarded the Zero Energy Certification by the International Living Future Institute (ILFI).

A key feature of the building, which was designed to be energy efficient, is its rooftop hosting more than 1,200 photovoltaic (PV) panels to harness solar energy. This factors into the objective of the building’s design as it is expected to feed a higher surplus of energy back into the energy grid over a lifespan of 25 years.

LYSAGHT® KLIP-LOK® 406 roof system was chosen for the NUS SDE4’s solar panel installation as it provides an ideal platform for mounting solar panels, where the mounting structure can clamps onto the raised ribs of the KLIP-LOK® 406 roof system without having to make any holes. It is also able to accommodate roof pitches from as low as 2 degrees for solar panels to attain the best performance and harvest more energy.

Further, metal roofs are perfect pairing for solar when it comes to an eco-friendly construction because they offer a solid surface and long-term durability for solar panel installation.

To counter the potential adverse effect of external weather, BlueScope’s recommended COLORBOND® ULTRA steel to deliver long term superior corrosion resistance as its external cladding finish material. To align with the push towards greener environment, COLORBOND® ULTRA steel is incorporated with THERMATECH® solar reflectance technology which allows for the external cladding to absorb less heat* from the sun, effectively minimizing the urban heat island effect.

The building, which was fully operational since January 2019, has went on a winning streak of multiple awards which includes the Architecture MasterPrize 2020 in the Institutional Architecture Category, the Blueprint Awards 2019 for Best Public Use Project with Public Funding, the Green Mark Platinum certification by Singapore’s Building and Construction Authority, and is the first university building in the world to achieve WELL Certified™ Gold, a premier building standard by the International WELL Building Institute (IWBI).
