  3. 3. Insulating BuildingsReduces the cooling requirements by 10% as compared to conventional buildings.Improves the Mean Radiant Temperature by 28% thereby increasing human comfort.
  4. 4. Insulating Material - CharacteristicsPerformanceInstallation method & QualityCost per square feetResistance ValueLow MRTEffect on the occupants & environment
  5. 5. Heat Transfer from Conventional Building Wall- AprilWatt/m2 80 70 60 50 West Wall 40 East Wall 30 South Wall North Wal 20 10 0 1 3 5 7 9 11 13 15 17 19 21 23 1 3 5 7 9 11 Time
  6. 6. Heat Transfer from West Side Wall with Different Insulating Materials - AprilWatt/m2 80 70 Type of the Material Heat Absorbed (watt/m2) Used 60 Concrete Wall 76 50 Concrete Wall 40 4 inch Brick Wall Brick wall 73 30 4 inch masoury Wall Exterior Insulated Wall 20 Masoury Wall 38 10 0 Exterior Insulated Wall 5 1 3 5 7 9 11 13 15 17 19 20 21 23 1 3 5 7 9 11 Time
  7. 7. Comparison of Heat Transfer from Interior Insulation of Envelope Conventional & Insulated Building Wall- April Interior Insulation absorbs much less than 80 Exterior Insulation 70 Watt/m2 Results – Reduction of Condensation 60 50 40 Thermal Bridge 4 inch Conventional Wall Exterior Insuated Wall 30 Interior Insulated Wall 20 10 0 1 3 5 8 1012141618202224 2 4 6 8 1012 Time
  8. 8. Heat Transfer from Roof with different Materials- AprilWatt/m2 140 Concrete Roof 4 inch 120 100 Concrete Tiles 80 Concrete Tiles with Air Space 60 Concrete Tile with Al Foil 40 Concrete Tile with 9mm 20 Bubble Foil Concrete Tile with 9 inch 0 Glasswool 1 3 5 7 9 11 13 15 17 19 21 23 Time
  9. 9. Conclusion Insulated Envelope will absorb approximately 9 times less heat than conventional building envelope. Reduces the electricity consumption by 50% approximately for cooling applications. Interior Insulation is better than exterior insulation but has ill- effect on the occupants. Reduces the requited size of the air conditioning system.
  10. 10. Future Scope Study of new insulating materials with high R- value. Combination of different materials to come up with a low cost outcome.
