Saving money on HVAC in a classified medical devices facility

An international Medical Devices manufacturer wanted to reduce their energy costs and carbon emissions to ensure their UK operations remained competitive in the global market. It is well known that HVAC typically accounts for 50-75% of a clean-rooms electrical energy use.

Large lab building – Variable Air Volume (VAV) Fume Cupboard Upgrade

This large lab implemented a Variable Air Volume (VAV) control strategy on nine constant air volume laboratory fume cupboards. The objective was to reduce conditioned air extraction when fume cupboard sashes were closed, thereby lowering both ventilation and heating energy consumption while maintaining laboratory safety standards.

Process Building – Ventilation Rebalancing Project

A ventilation optimisation and balancing project was undertaken in one of our clients process buildings to reduce excessive air supply volumes while maintaining required environmental and safety conditions.

Lab Building – Fume Cupboard Hibernation Programme

Following a review of the VAV control system and the use of fume cupboards energy-saving measures were implemented on laboratory fume cupboards within the lab Building.  The project focused on reducing ventilation energy consumption through improved fume cupboard control and operational management.
