• AstraZeneca is a major international healthcare
  business engaged in the research, development,
  manufacture and marketing of prescription
  pharmaceuticals and the supply of healthcare
  services.
• It is one of the world's leading pharmaceutical
  companies with healthcare sales of 26.47
  billion.
• AstraZeneca is listed in the Dow Jones
  sustainability index (global) as well as the
  FTSE4 good index.

4

• AstraZeneca Cheshire
• 2 Sites Alderley Park Research

5

• Macclesfield - Manufacturing

6

• Energy Consumption approx 24 million
• Floor area of heated buildings 390,000m2
• 8000 Employees

7

• 60 to 70 of energy consumed is associated with
  HVAC systems.
• HVAC systems are used to maintain cleanliness in
  pharmaceutical manufacturing environments.
• HVAC systems are used to contain potent
  pharmaceutical products in addition to solvents
  to protect our employees

8

• Linked to our license to operate
• Health and Safety
• Regulatory Compliance
• The pharmaceutical industry is traditionally
  conservative about HVAC in these areas.

9

• Understanding / reducing energy usage of
  existing facilities.
• Monitoring energy consumption is the first
  fundamental in being in a position to conserve
  energy.
• Investment made into Metering and on-line
  monitoring of electricity consumption and steam
  at Macclesfield.
• 600k invested over 4 years since 2003

10

• 380 Electricity Meters
• 26 steam meters
• 3 water meters
• 3 nitrogen meters

11

• Existing savings can be monitored and maintained
• Adverse energy usage trends can be quickly
  identified and rectified
• Future savings can be identified faster than if
  no system in place
• Demonstrate to building owners / users how much
  energy is being consumed and how much it costs,
  for example each month
• Building owners / staff aware of the cost of
  energy they consume critical in ensuring users
  manage consumption

12

• 2006 AZ Cheshire received EUETS carbon credits
  which were sold for 800, 000
• Linked to earlier decision to install CHP at
  Macclesfield.
• AZ decided to re-invest this money into energy
  efficiency projects
• 150,000 on the first phase of Stark at Alderley
  Park

13

• AZE Embarked on a rolling programme of HVAC
  optimisation works.
• To date 9 projects worth 1.3 million sanctioned
  or in for sanction
• Paying back between 1.5 and 5 years.
• What are we doing?
• Nothing Complicated!
• Turn it down
• Turn it off
• Set it back
• All while maintaining business as usual.

• Controlling energy consumption in our new
  facilities.
• Part L is generally not directed at our
  buildings.
• We must comply but far greater energy savings
  available from optimising our processes.

16

• Example
• Applying Variable Air Volume fume hood control
  and heat recovery to the new PRD facility
  Macclesfield.
• Should use 15 of the energy (per fume hood) of
  the facility it replaces.
• 220 fume hoods, conventional annual running
  costs of 1300 each.

17

• Automatic Closing Sashes
• Widely adopted by our Swedish sites

18
Sustainability Network

• Preparation and Education around sustainable
  solutions
• Enabling timely input into projects
• Missed opportunities
• Avoids repeat effort in evaluating opportunities

19

What Next

• Continue to Role out Stark at Alderley Park
• Continue with out HVAC optimisation work
• Continue to improve our new facilities.
• Benchmarking our energy use with other pharma
  companies.
