Transcript

  • 1. Insulation forEnergy Saving & Sustainability Dr. Kailash Chandra Sr. Manager Technical, AIIG Insulate Today Insulate Today
  • 2. 1 Multi billion dollar conglomerate2 45 nationalities3 12,000 employees4 50 countries of operation5 300 brands
  • 3. Why to Insulate
  • 4. Why To Insulate Low EfficiencyWhat happens if temp is hot? Less Productivity Running to find comfort
  • 5. Why To Insulate We feel COMFORTABLE when temperature of air around us is 22 +2oC
  • 6. Why To Insulate To bring temperature of air around us as 22 +2oC Either cooling or heating is required
  • 7. Why To Insulate Cooling or Heating Higher temperature Energy difference (ΔT) between external atmosphere and around us leads to higher cooling or heating
  • 8. Why To Insulate Power plants producing electric energy for heating/cooling/air conditioning need a lot of fuel and produce unnecessary air pollution and emits CO2
  • 9. Why To Insulate Carbon Dioxide Emissions are responsible for about 80% of the problems related to Greenhouse Gas Emissions and CO2 is one of the six chemicals methane and Biomethane nitrous oxide hydrofluorocarbons perfluorocarbons sulfur hexafluoride
  • 10. Why To Insulate Carbon Dioxide Emission have caused CO2 concentrations in the atmosphere to reach 387 ppm - over 100 ppm higher than pre- industrial revolution levels that were at 280 ppmCO2 is the main cause for Greenhouse effect and hence Global Warming The total global temperature increase from the 1850s throught to 2005 is 0.76°C Global average temp. is forecast to rise 4°C (7.2°F) toward the end of the 21st century, and this is a mere 90 years away!Doubling of CO2 levels to 550 ppm will in the end produce a 6°C increase.
  • 11. Why To Insulate Effect of Global Warming Draught Un predicted Rains Flood Forest Fire
  • 12. Why To Insulate Global warming is concern of Every responsible individual
  • 13. Why To Insulate What to do? Save Energy !
  • 14. Why To Insulate Energy use 40% of world energy is used in buildings; In GCC it is 50% The buildings have an enormous energy-saving –potential Industry 28% Buildings 40% Transport 32% Source: EURIMA, ECOFIS-study "Mitigation of CO2 Emissions from the Building Stock" Beyond the EU Directive on the Energy Performance of Buildings
  • 15. Why To Insulate Typical Energy consumption of a private household Better savings are expected in GCC due to lack of stringent building code Hot water 11,5% Light 1,5% House hold facilities 11,5% Final energy consumption 2002; Electricity, oil, gas, coal, etc Source: VDEW 2002 Heating/cooling 75,5%
  • 16. Why To Insulate HOW? Simply insulate Simply insulate
  • 17. Insulation
  • 18. Insulation INSULATION -Types A. Inorganic (Mineral Based) Glass wool Rock wool Slag wool Types of Cellular Glass (Foam Glass) commonly Calcium silicate Ceramic wool used Perlite/Vermiculate Insulation Sand Lime Aerated Block (White Block) B. Organic (Plastic Based) Rubber Foam Phenolic Foam PUR / PIR Foam Polystyrene Foam – EPS/XPS PE Foam

  • 23. Insulation Fire Test Videos
  • 24. Insulation selection
  • 25. Insulation Selection based on sustainability criteria Preference for an insulation material among the given options shall be based on Usage of Raw material Handling, transportation and storage Application Requirement Safe to Human Throughout Life Performances (Aging effect) Emissions after in use Fire Class Behaviour during fire Impact on environment (ODP & GWP)
  • 26. Insulation Selection based on sustainability criteria Let’s go with confidence ! By opting Mineral Wool Insulation (Glass wool & Rock wool)
  • 27. Insulation Selection based on sustainability criteriaBecause Mineral Wool (Glass wool & Rock wool) Insulation Are made from abundantly available raw materials (minerals) on the earth Are available as flexible, semi rigid and rigid Are light in weight and compressible Are suitable in wide range of temperature from – 200 oC to + 800 oC Does not promote growth of mould, bacteria and fungus Does not show any aging Are Fire Safe; Resist the fire and achieve highest class of fire safety (Euro Class A1) Environment Friendly – Zero GWP and Zero ODP Can meet almost all application requirements in the buildingAnd moreover “Buy one and get one free” rule is applicable due totheir dual performances ( Acoustic and Thermal Insulation)
