Human Centric Lighting in an office building
Improving the light environment of an office building with different technological solution
August 2021 - PDF 1.76MB
By: Luo Tao

In this office building, a lighting retrofit with Human Centric Lighting (HCL) system is provided..The HCL can fully change brightness and colour temperature. Based on ZPLC (Zero Power Line Communications) technology, it takes less than three months to complete the replacement and commissioning, without changing the original power line. After renovation, the luminous environment was greatly improved, while achieving more than 60% energy saving compared to the previous lighting system.
