Cleanroom facilities consume 5-50 times more energy than commercial spaces in the same sizes to achieve specified air cleanliness. Recent design and research developments focus more on achieving high performance while reducing energy consumption and improving sustainability. The seminar starts with a presentation addressing general cleanroom design criteria, such as cleanliness, particle, temperature, humidity, pressure, filter type and exhaust/make-up air in relationship with energy use. The second presentation reveals the findings from recent ASHRAE project which utilized real-time particle sensors to trace particle migration between rooms of different cleanliness classes and pressures to identify the minimum pressure differentials under various scenarios and conditions. The last topic covers case studies in energy reductions by using particle monitoring to reduce airflow, by recapturing lost pressure air, and by switching from ducted to fan-powered systems, etc.
