What is this standard about?
It gives recommendations on reducing energy consumption and maintaining energy efficiency in new and existing cleanrooms and clean air devices. It supports the classifications outlined in BS EN ISO 14644-1.
Who is this standard for?
Users of cleanroom technology such as:
- Hospitals and medical premises
- Life-sciences
- Pharmaceutical and medical sciences
- Micro-electronics
- Aerospace
- Nuclear
Why should you use this standard?
Cleanroom cleanliness can be classified by the concentration of specific contaminants in the air or on surfaces in the cleanroom. Cleanrooms use a considerable amount of energy to provide large amounts of filtered and conditioned air to achieve the specified levels of cleanliness.
Some firms using cleanrooms report that heating and ventilating systems consume up to 80% of the total energy used in their manufacturing facility simply to deliver clean, conditioned air to critical operations. This energy is consumed by heating, cooling, humidification and fan power. Of this, fans required to move air can account for 35% to 50%, much of this being due to the extra energy required to overcome the high pressure differential required for the high efficiency filters and other ventilation components used in cleanrooms. There is therefore a significant potential for energy saving by diligent design in the installation of new cleanrooms, and by retrofit improvements and upgrades to existing facilities.
BS 8568 lists and explains measures that can be taken to reduce energy consumption in cleanrooms and applies to the whole range of “cleanroom technology”. It can be used from cleanrooms to clean air devices, including isolators, glove boxes and mini-environments as described in BS EN ISO 14644-7.
