  contribution
• Need to advance the environmental aspect of the
  construction industry
• Innovatively combined existing structural panel
  expertise with an environmental need to develop
  the Energi Panel

  chamber
• Air tight seal achieved using expandable foam
  tape
• First chamber runs continuously the full length
  of elevation behind main steelwork
• Plenums units are lapped at either end
• Secondary chamber houses low energy fan unit

Systems Restrictions

• Energi panel colours must be in excess of 75
  solar absorptivity.
• Energi Panel elevations must ideally be
  orientated within 25 East or West of South
  otherwise payback period increases dramatically
• The elevation height must be at least 3.5 metres
  in length from bottom of panel to access holes
• The Standalone system is limited to buildings
  with low temperature requirement buildings i.e.
  16 degrees
• An Integrated solution is applied to buildings
  requiring higher temperatures i.e. office
  buildings (21ºC) currently in development
• Cannot be applied in shaded areas or elevations
  with windows and doors.
• Energi Panel elevations must be continuous
  lengths of panel no lapping reduces system
  performance

Energi Panel Advantages

• Compared to the traditional Bolt On solar air
  collectors, Energi Panel has the advantage of
  being an integrated part of the insulated panel,
  therefore does not have the typically associated
• - Additional steel single skin
• - Supporting steelwork
• - Extra Panel Fixings
• - Additional Install time and labour
• - Extra Install costs
• - Increased Carbon Footprint (associated with
  extra steelwork, transport costs etc.)

Summary - Key Benefits

• Low cost
• Reliable renewable energy source
• Provides good payback on investment
• Large scale test buildings have shown heating
  costs can be reduced by up to 24
• The building CO2 emissions significantly reduced
• Increased chance of gaining planning permission
  (Merton Rule)
• Future proof building asset value
• Achieve a better EPDB rating
• Unique proposition ONLY structural insulated
  panel providing renewable solar collecting
  potential

15
Other benefits

• Flexible system i.e. can be utilised in a
  standalone heating capacity or can be integrated
  with the buildings HVAC system.
• Is available with the Kingspan TOTAL Guarantee
• Uses low maintenance long life components
• Kingspan Envirocare Technical Services are
  available to assist with building design to
  optimise performance
• Is available in a range of colours (obviously the
  darker the external colour of the panel the
  greater the solar absorption and subsequent
  renewable energy yield)

Energi Panel System Functionality

• The Energi Panel system works on a closed loop
  control system
• Internal temperature and collector air supply
  temperature dictates fan activation/deactivation
• Thermostat activates controllers when internal
  temperature is below preset level
• Fan activation is dependant on collector air
  supply temperature
• Fans create uniform negative pressure ensuring
  balanced airflow through crowns
• System continues to deliver heated fresh air
  until deactivated by thermostat or reduced levels
  of solar radiation

18
Speed Control Function

• Integrated speed control function to maximise
  heating capability
• Internal temperature requirements are programmed
  into controller
• Speed of the fan is dictated by the temperature
  differential between
• The minimum internal temperature requirement
• The air supply temperature from collector
• Low solar radiance intensity low fan speed
• High solar radiance intensity high fan speed

19
Test Houses

• Two 250m3 identical test houses constructed at
  the RD centre
• Both controlled to within the temperature range
  16-19ºC
• Control Building utilises a standard gas fired
  heater
• Energi Panel Building utilises a combination of
  Energi Panel SAH system and the gas fired heater
• Test house doors opened daily 8am-5pm to simulate
  industrial factory/warehouse environment

Monitoring and Data Acquisition

• DT800 Data-Takers installed in either test house.
• Data-Taker serves two purposes
• Control the internal environment of the building
• Record sensor readings at 5 minute intervals
• Internal air temperature sensors, electrical
  power and gas meters installed in both test
  houses
• Cumulative kWhr usage recorded for both test
  houses

23
Monitoring and Data Acquisition

• A range of sensors were applied to the Energi
  Panel SAH system with the purpose of
• Investigating the Energi Panels solar collector
  performance
• Calculate total kWhr solar heating delivered to
  the building
• Air temperature sensors air placed at inlet and
  exit of collector
• Solar Radiance sensors attached to collector
  surface
• Weather station erected chart the effect of
  changing weather conditions on Energi Panel
  performance

Test House Results

• The test houses have been monitored form Oct
  15th- Present
• Control Building 13162kWhr
• Energi Panel Building 10069kWhr
• To date the Energi Panel test house has utilised
  24 less energy than the control building, in
  maintaining the same heating performance
• The Energi Panel building has reduced carbon
  emissions by 685kgCO2
• Test data validated by Battle McCarthy

Energi Panel Performance Characteristics

• Rigorous testing carried out on external rig to
  establish Energi Panel performance curve
• Various flow rates tested and corresponding
  temperature curves establish
• Temperature curves enable an operating efficiency
  to be assigned to each flow rate
• Using the range of operating efficiencies a
  characteristic performance curve can be generated

28
Energi Panel Performance Characteristics

• Characteristic logarithmic curve representative
  the operating efficiency of the Energi Panel
  Solar Collector

29
Energi Panel Destratification System

• In conjunction with the Energi Panel Kingspan
  offer a destratification solution
• Destrat system reduces roof temperature
  minimising heat loss from roof
• Generates 4 air movements per hour resulting in a
  max temperature differential of 1ºC between roof
  and floor
• Benefits both Energi Panel SAH system and
  standard heating by evenly distributing delivered
  heat

30
Energi Panel Predictive Calculation Model

• Using test data it was possible to develop an
  Energi Panel predictive calculation model
• The model can be used to carry out a
  pre-feasibility study on a given project
  specification
• The model generates predicted energy savings
  associated with the installation of
• An area of Energi Panel
• Energi Panel Destratification
• To carry out a standard proposal the model
  utilises
• - A basic building heat loss model
• - RETScreen International weather database
• - RETScreen International Solar Energy Model
• A questionnaire is provided to customers for
  submission upon request of a project proposal
