GREEN MATTERS


It’s smart to be green


HVAC technologies are helping data centres become smarter and greener says Aermec UK’s general manager technical services, Andy Hawes.


D


ata centres support many critical services, from hospitals to fi nancial services. We all know of their strategic importance and how they require


large amounts of water, energy and land resource which continually comes under scrutiny. The data centre industry is making great progress in moving towards a more sustainable transformation that can be resilient to the impact of climate change. By reducing the environmental footprint of data centres, sustainability goals can be achieved. All economies are becoming increasingly digital and dependent on reliable infrastructures for essential and increasingly non-essential services. Governments are driving all industries towards a net zero goal through legislation, tighter building controls and moves towards lower GWP refrigerants.

The HVAC industry is playing a pivotal role by moving


towards more renewable energy sources, smarter technologies, energy effi cient designs and embracing embodied carbon initiatives. Two of the most pressing concerns for data centres are the use of limited resources, water, and power, particularly harmonics can also have a detrimental eff ect on a system’s effi ciency but are often overlooked. Harmonics (electrical pollution) sometimes underestimated, can require an increase in CAPEX and OPEX spending and attracting penalties when introduced to the grid. Data centres are moving towards increasing internal


temperatures in data centre halls in accordance with ASHRAE guidelines. Following a higher temperature strategy off ers more opportunities for free cooling which can help
