Energy Savings

HVAC Energy Savings

Cleanrooms typically have substantial energy usage, due to the requirement for high air change rates and the use of HEPA Filters to achieve air contamination control. The HVAC air conditioning serving these cleanroom facilities will typically run 24/7, creating a significant carbon footprint.

Clean Air Technologies have used our unique experience in order to develop a specialist service to achieve the optimum balance between energy consumption and regulatory compliance, in these specialist cleanroom facilities.

Our expertise gained with working with secondary pharmaceutical manufacturers allows us to speak their language, understanding and meeting the requirements of the 4 key stakeholders: –

• Quality
• Engineering
• Production
• Procurement

We believe in a staged approach with 3 distinct phases eliminating wastage and then challenging the site norm minimising contingency in terms of current SOP’s and regulatory compliance, associated with the air supply.

Non Intrusive HVAC Savings

An opportunity to identify, then realise, energy savings that can be achieved with no modification or changes to the infra structure of existing Air Delivery Systems. Achieving the best balance between system efficiency and regulatory compliance. Any change to the system performance must still conform to site performance requirements thus the system is bench-marked in terms of the following performance criterion.

• Particle Counts
• Room Clean ups
• Air Change Rates
• Temperature and Humidity control
• Pressure

Then potentials savings are identified in the form of a report from the collated data. Once the remedial works are implemented the system is then bench marked again by re-validation of all supporting data and actual savings are calculated.

Intrusive HVAC Savings

An opportunity to identify, then realise, energy savings that can be achieved with modification or changes to the infrastructure of existing Air Delivery Systems with The associated impact on Production, Capital Cost and Pay back. These can include –

• Fan / Fan Motor replacement
• Inverters
• Damper selection and control
• Night Setback for Air Change rates Temperature, Humidity

Each site will have different systems and requirements so each opportunity will be individual so a generic approach for the Phase A cannot be adopted however all the collated data can be incorporated into this phase.

Cleanroom Operational Savings

Having built an in-depth knowledge of licensing regulations and the necessary understanding of GMP procedures and protocols, we can realise energy and operational savings by challenging the site norm in terms of environmental conditions on a risk based analysis by challenging and minimising contingency that may have built up over years of production leading to the re-classification of areas, re-writing of SOP’s which in turn can realise substantial savings in terms of –

• Consumables
• Laundry
• Fan Energy

The generic energy saving activities have all been mapped and processed flow to allow transparency for our client’s facilitating communication and reflecting the requirements of a regulated industry.
