Energi Panel

1. Energi Panel

2. Introduction • Kingspan aims to provide solutions to meet the construction industries needs • Growing emphasis on building “greener buildings” as a result of - Escalating fuel prices - Commitment to reduce CO2 emissions • UK Merton Rule - 10% renewable energy 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

3. Energi Panel Product Description • Energi Panel derived from existing Five Crown profile. • Hollowed crown made possible by patented manufacturing technique • Void dimensions specifically engineered to ensure optimal air flow to heat transfer • Optimal thermal and structural characteristics of the Five Crown panel maintained – added foam thickness • Energi Panel has dual functionality

6. Energi Panel Component Parts • Number of features associated with the solar functionality of the product • 0.5 mm steel solar collector • Profiled Foam fillers • Mesh Inserts • Stepped Energi Panel drip flashing • Internal crown access holes

7. Energi Panel Component Parts • Stepped Energi Panel drip flashing • Internal crown access holes

8. Energi Panel Collection System • Double Chamber Arrangement • Mechanically affixed back to liner tray using peel rivets • Pre-drilled holes encapsulated inside plenum 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

10. 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

11. 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

12. Test Houses • Two 250m3 identical test houses constructed at the R&D 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

15. 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

16. 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

17. 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

20. 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

21. Energi Panel Performance Characteristics • Characteristic logarithmic curve representative the operating efficiency of the Energi Panel Solar Collector

22. 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

23. 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

24. 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 CarbonFootprint (associated with extra steelwork, transport costs etc.)

25. 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

26. 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 Panel 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)
