IDENTIFYING HVAC ENERGY REDUCTION STRATEGIES FOR AN ORAL SOLID DOSE PHARMACEUTICAL MANUFACTURING FACILITY
Data was requested from the client site on the energy consumption, HVAC system design, operation and critical product quality requirements. EECO2 analysed this data to determine the likely opportunities for efficiency improvements in each process area. During the site survey, potential opportunities were assessed on 80% of the HVAC systems. These were evaluated and discussed with key stakeholders, to determine a viable site plan to implement the improvements identified.
We identified a number of strategies with significant cumulative energy savings, including:
Switch off fume cupboards out of hours, with appropriate controls in place.
Switch off or reduce air change rates of HVAC units in areas not currently used for production.
Rebalance air distribution systems to minimise extract whilst providing sufficient outside air for dust extractor and leakage to maintain pressurisation.
Install bypass to dehumidifiers in liquids area and raise humidity setpoint within compliance limits.
Improve door sealing and fabric to reduce air leakage.
We also recommended a practical implementation plan which would ensure that changes can be made safely and efficiently whilst maintaining quality and compliance. The plan was agreed in principle with all stakeholders, including Quality Assurance and Validation groups. Much of the implementation can be delivered by the local site team, supplemented by EECO2 technical and project management expertise when requested.
You always open our eyes to the savings opportunities that exist and how to go about implementing them. Thanks.
