REVIVAL STEVENAGE
  • Delivery Context of Stevenage Work Packages
  • The 14 Stevenage work packages are being
    delivered as part of Phased programme of
    refurbishment of an occupied public building.
  • They are part of 8 individual refurbishment
    projects with different funding and timescales.
  • The 8 projects have a total value of 2.35m
  • (3.3m Euros)
  • The Revival financial contribution is 48k
  • (67,000 Euros) 2

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.

Lighting Controls
  • 3rd floor lighting to main open plan area is
    controlled by Solar sensors
  • The lighting in 2 meeting rooms and 2 offices
    are controlled by occupancy sensors.

Solar Water Heating
31 m2 of solar panels 35kw auxiliary gas boiler
21
REVIVAL STEVENAGE
  • Solar Water Heating
  • Existing Hot Water Cylinders could not be reused.
    Final design included for
  • New hot water cylinders
  • Installation of high efficiency gas boiler
  • ( installation costs considerably more than
    original budget)
  • Installation was completed in September 2006

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)
28

Problem Encountered in last reporting period
  • Solar Panels damaged in storm during installation

Problem Encountered in last reporting period
  • Serious Flood to 3rd floor 3 days after
    completion

REVIVAL STEVENAGE
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
efficiency

REVIVAL STEVENAGE
  • 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,

32
REVIVAL STEVENAGE
  • Monitoring for 2007
  • Area Usage monitoring
  • Sample monitoring of Actual occupancy levels
  • Actual periods of use
  • Sample Monitoring of Plant Equipment Operating
    Periods
  • Lighting (Summer Winter)
  • Cooldeck system (summer only)
  • Oxegen ventilation units (Summer Winter)
  • Cooldeck system Performance Monitoring
  • Full 12 point temperature monitoring to be
    repeated
  • PCM performance to be monitored with addition of
    Heat flux sensor

  • Monitoring for 2007
  • Solar Hot Water System Monitoring
  • Gas, Water Electricity consumption
  • ( individual meters for all elements have been
    installed in the boiler room)
  • Solar generation (KWH)
  • Whole building occupancy hours
  • Building a profile of hot water demand and
    assessing match to solar supply capacity

35
Summary of Monitoring Programme 2007
36
REVIVAL STEVENAGE
  • A significant Investment has been made in
    installing monitoring equipment including
    additions to central BEMS
  • Gas meter
  • Solar Heat Meter
  • Water Meter
