BS 8568:2013 Cleanroom energy. Code of practice for improving energy efficiency in cleanrooms and clean air devices

What is BS 8568?

BS 8568 is a new British Standard that 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.

BS 8568 does not apply to the energy efficiency of process equipment, except where it affects the cleanroom environment. It also does not address related production processes such as water treatment, oven, autoclave and stress cycling operations that can also create significant energy demands.

What kind of energy does a cleanroom use?

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. A considerable amount of energy is also used to achieve:

a) The necessary temperature and relative humidity for the process in the cleanroom and for personnel comfort;
b) The necessary pressurization of the space; and
c) In some cases, the necessary airflow volume flow rate for unidirectional airflow and to a reduced extent non-unidirectional airflow.

How can BS 8568 help you to save on energy costs in a cleanroom or clear air device?

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 14644-7.

Cleanroom technology is used by organizations within the life-sciences, micro-electronics, aerospace and nuclear fields. The life-sciences sector includes hospital, pharmaceutical and medical device activities. BS 8568 is therefore a key standard to help you make sure that your cleanroom technology is energy efficient.
