Mechanical Top Up Cooling Units

• The new Squid top up mechanical cooling units
  are operational and were used towards the end of
  the summer period.
• These units were also retrofitted to the 2nd and
  6th floors.
• They are currently set to operate when internal
  temperature reaches 27Deg. C.
• Design assumes around 200 hours operation per
  summer.

Winter Ventilation to Old Block

• To provide acceptable winter ventilation to the
  old block, a system of Co2 controlled radiators
  is being installed.
• The system is called oXygen manufactured by
  Jaga of Belgium
• 6 oXygen radiators have been installed as part
  of the 3rd floor project

26
REVIVAL STEVENAGE

• System has Co2 controls and can also be used in
  summer to provide controlled ventilation within
  the passive cooled area

27
Two oXegen units within single Radiator
oXegen units are controlled through power
circuit (Laptop is part of control system will
allow detailed monitoring)

Monitoring Evaluation Programme

• Stevenage Monitoring Exercise aims to demonstrate
  improvements in energy performance against a
  target Co2 reduction of 50

Stevenage project will show efficiency
improvements both in terms of the buildings
-Energy performance -Space Utilisation

• Monitoring for 2007

• Monitoring of all REVIVAL Elements will take
  place in 2007
• As well as whole building consumption monitoring,
  Main Emphasis will be Comprehensive Monitoring of
  3rd Floor Old Block, including
• Consumption Monitoring
• Power to lighting office equipment
• Power to Cooldeck, top up cooling, Oxegen units
• Comfort Conditioning Monitoring
• Temperature, RH, Internal Co2,
