Data Centre Trivia
Welcome to our Data Centre Trivia hub, where we gather a growing list of questions designed to challenge and educate anyone working in or curious about the world of digital infrastructure.
Each month on Australian IT Services’ LinkedIn, we share a new trivia question inspired by data centre cleaning companies, real-world data centre operations, technology, sustainability and best practice. This blog brings them together so you can quiz yourself, test your team or spark some friendly competition in the comms room.

2. How much extra energy can HVAC systems consume when coils and air handling components become fouled with dust, debris and biofilm?
Industry research has shown that contaminated HVAC components and coil fouling can create significant energy penalties within cooling systems.
According to published HVAC studies, biofouling and particulate build-up between maintenance intervals can increase energy consumption by approximately 10–15% due to restricted airflow and reduced heat transfer efficiency.
Additional studies have found that cleaning fouled coils can significantly improve airflow capacity while reducing fan energy consumption and system strain.
Industry Sources & Research
• ACEEE (American Council for an Energy-Efficient Economy) reported that dirty HVAC coils and airflow restrictions can reduce system performance and increase energy consumption.
• A hospital HVAC case study by RTF Energy Solutions found that coil cleaning improved airflow from 8,407 CFM to 13,839 CFM and reduced fan energy consumption, delivering measurable energy savings.
• NADCA research also identified supply airflow improvements of up to 46% following HVAC system cleaning.
In critical environments such as data centres, maintaining a clean technical environment can help minimise airborne dust and particulate contamination that may contribute to HVAC fouling over time.
Australian IT Services provides specialised antistatic technical cleaning services designed to help reduce contamination risks within sensitive environments including data centres, computer and server rooms and critical infrastructure facilities.
