Embracing sustainability : The panel highlights the need for the data centre industry to prioritise sustainability . As the sector continues to grow , there is a concern that current practices may not align with sustainable principles . The panel agrees on the importance of learning from past experiences and implementing lessons to drive positive change . This includes a focus on sustainability from a global perspective , with specific attention to regions like Africa .
Harnessing heat recovery : One of the key strategies discussed is the significant potential of heat recovery in data centres . The panel emphasises the importance of exploring heat recovery applications , particularly in regions such as the colder Nordic countries and other parts of Europe . While the market demand for heat recovery may vary , there is a consensus on its value in reducing energy waste . By capturing and utilising excess heat , data centres can achieve both energy efficiency and sustainability goals .
Addressing water and power scarcity : Water and power scarcity emerge as critical considerations in data centre design . The panel recognises the need to account for these challenges when developing cooling systems . To mitigate water scarcity , alternatives to traditional cooling methods , such as refrigerant usage reduction , are explored . Additionally , the discussion touches on the importance of considering power scarcity and the potential for data centres to integrate with local energy grids , benefiting both the centres and surrounding communities .
Exploring efficient cooling technologies : The panel acknowledges the importance of adopting efficient cooling technologies to minimise energy consumption . The panellists highlight the need to reduce reliance on refrigerants and explore alternative cooling approaches . Examples include direct and indirect air cooling , liquid cooling , and the integration of renewable energy sources . By leveraging advanced cooling technologies , data centres can optimise energy usage , reduce carbon emissions , and enhance overall sustainability .
THE VITAL IMPORTANCE OF AIR CONDITIONING AND COOLING IN DATA CENTRE CONSTRUCTION One delegate to the Pan-African DataCentre Exhibition & Conference estimated the growth trajectory for the Africawide data centre market at 600 % over the next four years , based on scheduled projects and orders .
With the increasing demand for data storage and processing , ensuring the proper management of heat , temperature , humidity , and air quality is essential . Implementing efficient and reliable cooling systems not only protects valuable equipment but also optimises energy consumption , reduces downtime , and contributes to the overall success and longevity of data centres in the digital era . Schneider Electric has an area of specialisation in data centre building management systems ( BMS ) solutions and has a strong presence in Africa .
Describing the need for BMS in data centres , Mark Freeman , offer manager Digital Buildings , Anglophone Africa at Schneider Electric , says : “ BMS is particularly well-suited for buildings with complex requirements such as data centres , hospitals , hotels , and commercial office parks . These facilities often consume more energy than typical buildings and require precise monitoring and control . Additionally , BMS

can optimise energy usage and space allocation , allowing for efficient segregation of offices and dynamic adjustments to HVAC systems . Any building that benefits from intelligent control , improved energy management , and cost savings can greatly benefit from a BMS implementation .
“ Data centres require meticulous control and monitoring due to their constant energy demand and the need for temperature and humidity regulation . BMS offers advanced capabilities for managing HVAC systems , particularly the intricate cooling requirements common to data centres . By integrating with various sensors and equipment , BMS provides real-time monitoring and control of temperature , humidity , and airflow . This ensures that servers operate within optimal conditions , mitigating the risk of overheating and potential system failures .
“ Unlike traditional buildings , data centres have specific challenges that need to be addressed . The constant load on HVAC systems and the sensitivity of equipment necessitates precise temperature management . BMS helps detect and visualise potential hotspots within the data centre , allowing operators to distribute cooling more effectively and prevent equipment failures . Additionally , data centres require robust backup power solutions , and BMS plays a vital role in monitoring and controlling generators , ensuring uninterrupted power supply during utility outages ,” says Freeman .
“ BMS is particularly wellsuited for buildings with complex requirements such as data centres , hospitals , hotels , and commercial office parks .
