Environment and Conservation Fund Green Building Education and Capacity Building Programmes - Micro-credential Topical Course - Energy-efficient Airflow Management for Green Data Centres: Principles, Practices and Retrofit Approaches

Funded by the Environment and Conservation Fund and organised by the Hong Kong Green Building Council (HKGBC), this micro-credential topical course series is designed to provide participants with more in-depth continuing education than traditional CPD webinars. It enables practitioners to construct weekend or after-hours study programmes that meet their development needs. Courses will be rolled out at a frequency of about 1-2 courses per month, throughout a period of two years from 1 September 2025 to 31 August 2027. Participants taking 20 or more courses can apply for a skill enhancement certificate from HKGBC, certifying their significant efforts in studying green building.

Micro-Credential Topical Course – Energy-efficient Airflow Management for Green Data Centres: Principles, Practices and Retrofit Approaches

Data centres consume massive amounts of energy, converting a significant portion of electrical power into waste heat. Carrying out proper airflow management and hot/cold aisle separation is essential to maximise cooling efficiency and lower Power Usage Effectiveness (PUE). As rising AI loads push rack densities to extreme limits, facility operators must transition from traditional air cooling to advanced systems to manage high thermal loads. This course details how to optimise existing infrastructure using practical retrofit strategies such as containment, blanking panels, real-time sensor monitoring, and Computational Fluid Dynamics (CFD) modelling to eliminate hotspots and reduce operational costs.

This course consists of the following two parts:

Part 1 – Understanding Data Centre Airflow and Cooling Efficiency

  • Key drivers of data centre energy consumption and cooling demand
  • The relationship between airflow management, thermal performance and Power Usage Effectiveness (PUE)
  • Common airflow challenges, including hotspots, air recirculation, bypass airflow and uneven rack cooling
  • The impact of rising rack densities and AI-related computing loads
  • Principles of hot-aisle and cold-aisle management

Part 2 – Practical Improvement and Retrofit Strategies

  • Airflow optimisation measures for existing data centres and server rooms
  • Containment, blanking panels, rack configuration and fan-assisted airflow management
  • Dynamic airflow control using temperature and operational data
  • Using monitoring, testing and CFD analysis to evaluate improvement opportunities
  • Implementation considerations, common challenges and lessons learnt
  • Illustrative applications and practical case examples
