    • 5. A History lesson:
      To our knowledge there has never been any scientifically based work to identify Pharma Manufacturing ACPH requirements
      Current ACPH “Guidelines” are based upon experiments to identify the high failure rates of rocket gyroscopes in the 1950’s for the USAF
      Similarly for Aseptic manufacturing laminar air velocities have not been fully challenged.
      Compliance requirements are based upon air quality
      Collaborative scientifically based review of ACPH & Laminarity has just been completed
      The initial indications are – prepare for change!
    • 6. An Inconvenient Truth!
      Compliance driven, business risk aversion, has resulted in over designed systems for many years
      HVAC systems commonly found to be 50% + oversized
      This has now come back to haunt us, as we are now paying higher energy costs and increased emissions
      Key Challenge; maintaining compliance and product quality, at the same time as reducing energy costs
      Otherwise how do you retain your competitive edge, in a global market, if your “fixed” overhead is constantly increasing?
      The recession may temporarily slow Energy cost increases, providing a breathing space to mitigate your baseline Energy costs
      Corporate Responsibility – Sustainability. ISO16001
    • 7. The Other Inconvenient Truth!
    • 8. Sustainable Energy Improvement Process
      (SEIP) Using OE Principles

    • 22. HVAC - The “Usual suspects”
      Top 10 most commonly found opportunities:
      High air change rates.
      High fresh air volumes.
      Challenge area classifications & manufacturing demand.
      Operational changes made in areas served.
      High energy, low capacity filtration.
      BMS not Optimised.
      Dehumidifiers not Optimised.
      Few VSD’s & where fitted left on “manual”
      Switch off/reduce HVAC during none operational hours
      Laboratory fume cupboards - upgrades
    • 23. Identify “size of the prize”
    • 24. Sample – Energy Audit Summary
    • 25. Improve
    • 26. Energy Design Flow Path
      Production Area:
      Product & Compliance
      need driven
      Design HVAC to
      Meet - not exceed
      Chillers &
      Support Utilities
      1. Identify current product need
      2. Review; Classification & Pressure Regimes etc.
      3. Energy Audit space
      4. Calculate required ACPH
      5. Design HVAC Plant to meet 1>4
      6. Ensure all elements of design are Energy Efficient
      7. System should be fit for purpose
      8. Designed to support 1>7
      9. Using Energy Efficiency;
      Best Engineering Practice
      10. Integrate relevant innovation
      Minimising Air Change Rates is the key issue
    • 27. Quick Win Opportunities?:
      Design review of HVAC systems – ACPH & Fresh air volumes
      Review potential to switch off or set back air volumes in non cGMP areas at nights & week ends
      Secondary Packaging
      Modify fresh air HVAC systems to recirculation system with “free cooling “ where viable – mitigate potential cross contamination issues - filtration
      BMS Optimisation, strategy review, system maintenance
      VSD’s with volume control reduces Energy demand & improves flexibility
      Review current AHU & terminal filtration, replace with low energy types
      Challenge requirement for dehumidification & energy upgrade when required
    • 28. Big Win Opportunities!
      Minimise fresh air volumes to achieve pressure cascades, overcome loss & personnel requirements
      • Fresh air volume has a significant impact on HVAC Energy demand
      • 29. Season dependant it requires: cooling, heating, filtering, dehumidifying etc
      • 30. If it requires dehumidification: reactivation heating, cooling & filtration
      • 31. The Dehumidification process uses significant energy
      Minimise air change rates (ACPH) to meet air quality requirements & Production equipment heat loads
      • Excessive ACPH increases fan power & cooling demand for no benefit
      • 32. Most areas have excessive ACPH
      • 33. Review potential to set back ACPH during none operation hours
      Identify actual HVAC operational hours vs Manufacturing schedules
    • 34. Key Project Issues;
      Energy Efficiency need not compromise : Compliance, product quality, quantity or safety
      Structured approach to identifying and safely delivering Energy Efficiency
      Functional Requirement Specification (FRS): area classifications, product & production requirements, identifies cGMP & change control requirements
      Identify viable solutions to reduce HVAC energy
      Review the Production Area’s current and projected HVAC demand
      Balance that demand with the most Energy Efficient HVAC operation
      Plan production impact minimisation
      Energy upgrading can qualify for Enhanced Capital Allowances (EHA)
    • 35. Project Development Process:
      Following completion of HVAC Energy Audit:
      Step 1: Prioritise upgrades based on: best cost savings @ least business risk
      Step 2: Commence with “quick win” opportunities
      Step 3: Complete FRS risk assessment with: Eng/QA/Users/EHS
      Step 4: Devise low impact implementation strategy
      Step 5: Programme to minimise and manage shutdowns & business impact
      Step 6: Verify savings projected have been delivered
    • 36. Energy Focused Strategic Planning:
      Development of Business Risk Strategic Planning:
      Virgin Refrigerant R22 ceased in January 2010, usage banned in 2015 – affects older chillers
      Phased Chiller replacement with energy efficient replacements based in LCCA
      Chiller replacement design load based on reduced cooling demand not historical
      Recommission HVAC air systems to ensure they meet cGMP Guides
      Install EEF1 motors on failure or VSD installation
      Phased upgrade to low energy filtration
      Dust extract units: air pulse on ΔP & review carrier air velocity
    • 37. Re - Measure
    • 38. Low Cost MM&T

    • 40. Way Forward
      Think that you have already picked your “low hanging fruit” – think again!
      Take ownership of energy management
      Identify where your energy is used
      If you cannot measure it – you cannot manage it!
      Team work solutions – Engineering/QA/Production/EHS
      Do not be afraid to challenge/challenge/challenge – perceived “standards”
      The bottom line is!
      If you do not make it cheaper – someone else will!
