IDENTIFYING HVAC ENERGY REDUCTION STRATEGIES AT A PHARMACEUTICAL MANUFACTURING FACILITY
Data was requested from the client site on the energy consumption, HVAC system design, operation and critical product quality requirements in key process (higher grade GMP) areas.
EECO2 analysed this data to determine the likely opportunities for efficiency improvements. 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:
Add VSD to extraction fans in several key areas to enable fresh air to be reduced
Reduce air change rates
Introduce temperature and relative humidity deadbands
Introduce PID loop tuning
Install control sensors and implement turn off strategy for finished goods warehouse
Our recommendations included a practical plan for implementation including budgets and payback period. This project assessed 43% of the site HVAC energy consumption, and therefore recommended a thorough, focused review of non-classified areas, including secondary packaging, laboratories and other non-GMP areas which were not included in this initial scope.
You always open our eyes to the savings opportunities that exist and how to go about implementing them. Thanks.

Energy savings identified (per year)
(11% site energy reduction)
Energy cost savings identified (per year)
Emissions reduction (per year)
of CO2 emissions
The savings identified have an estimated overall payback period of less than 2 years.
A further $220,000 of annual savings are likely on the remaining HVAC systems not assessed.
