Hwee Jan’s green building transformation: from efficiency to excellence
At Hwee Jan, we believe sustainability is not just a buzzword — it’s a responsibility. That’s why we’ve made a bold move to significantly reduce our carbon footprint while future-proofing our facilities.
We’re proud to share that our factory has undergone a complete green transformation — and the results speak for themselves.
Harnessing the sun: 590 solar panels installed


In our biggest energy shift to date, we installed 590 pieces of high-efficiency monocrystalline bifacial solar modules, each rated at 585Wp. This brings our total solar capacity to 345.15 kWp, generating an impressive 431,000 kWh per year — enough to fully power our daily operations.
The best part? Our system is already meeting 100% of our energy needs, and we’ve still left room for more panels in future phases.
Upgrading to 5-tick air conditioning systems
As part of our energy efficiency overhaul, we replaced all outdated air conditioning units (previously ranging from 1- to 3-tick efficiency ratings) with top-rated 5-tick models. These new units not only reduce energy consumption but also improve cooling performance for our employees and equipment.
Switching to LED lighting
Lighting also plays a major role in building energy usage. We replaced all 319 non-LED lights throughout the facility with energy-efficient LED alternatives. This simple but impactful move significantly lowered our electricity usage and improved workplace illumination.
BCA Green Mark Platinum Super Low Energy (SLE)


These upgrades have culminated in our proudest achievement yet — earning the BCA Green Mark Platinum Super Low Energy (SLE) award, Singapore’s highest green building certification.
This award is a testament to our commitment to sustainable infrastructure and operational excellence, recognizing organizations that go beyond compliance to drive real change.
Our commitment to a greener future
Our green transformation is just the beginning. We see sustainability as a continuous journey and will keep investing in technologies and practices that reduce waste, save energy, and protect our planet — one initiative at a time.
Through solar power integration and energy-efficient upgrades, we’ve shown that even industrial manufacturers can play a vital role in Singapore’s transition to a low-carbon future. We hope our journey encourages more businesses in supporting industries to step forward too.
