HGC GlobalCentre Limited (HGCGC) provides data centre services for local and international organizations. It includes data centre facilities, cabinet colocation, managed services, IT operation outsourcing and business continuity service. To become a sustainable green data centre, HGCGC’s Kwai Chung facility establishes, implements and maintains ISO 50001 Energy Management System (EnMS) to save energy and enhance energy efficiency.

International Organization for Standardization (ISO) published ISO 50001 standard in June 2011. The purpose of EnMS is to help different industries to manage energy effectively. Through EnMS, it is expected that energy cost and greenhouse gas emission can be reduced in order that some negative environmental impacts can be alleviated.

HGCGC implements EnMS based on the Plan-Do-Check-Act framework. It sets up the scope of EnMS and energy policy in the planning stage. Then, it compares between energy baseline and energy performance indicator, and establishes energy management objectives and targets according to the result of energy review. Also, HGCGC forms an Energy Management Team to execute energy management action plan. The one of energy saving measures is to monitor and maintain optimal chiller water temperature regularly and to install variable frequency drive for pumps and chillers. HGCGC conducts internal audit regularly to assess the performance of EnMS for continual improvement.

Moreover, HGCGC evaluates its energy policy regularly. Before the evaluation, it collects and analyzes the energy consumption data of energy saving measures of its data centre in Kwai Chung in order to establish a better energy management action plan.“ISO 50001 EnMS is a long-term energy management tool for continued energy saving. We will also adopt ISO 50001 EnMS in our upcoming data centres,”said Mr. Y C Lee, Head of Data Centre of HGCGC. This shows ISO 50001 EnMS is a very critical element in energy management.

Since the Earth’s resources are scarce, we need to advocate environmental protection so as to reduce the usage of resources and save the Earth. With ISO 50001 certification of its Kwai Chung facility, HGCGC has set a role model for the data centre industry. We hope that ISO 50001 EnMS can be adopted by more organisations for sustainable development.
