  • 3. Vapour movement in a traditionally built home. We can improve efficiency, but must be careful not to compromise this dynamic.
  • 4. Traditional passive systems
  • 5. This Edinburgh house, built in 1840, featured a passive vent system Air was heated in a boiler in the basement, and routed up through the house, via cornices, ducts and floorboards.
  • 6. Vents at ground level
  • 7. Hidden vents in hood moulding
  • 8. If we get it wrong..
  • 9. 25% 35% 10% 20% 10%
  • 10. &nbsp;
  • 11. Baseline measurements
  • 12. Air leakage and improvements
  • 13. Draft Stripping
  • 14. Improvements tested in lab at Glasgow Caledonian
  • 15. Existing options – shutters &amp; blinds – gave significant improvements
  • 16. Improved shutters – U value of 1.8
  • 17. shutters, curtains and blinds – reduce heat loss by 62%
  • 18. Secondary glazing
  • 19. Secondary glazing : U Value 1.7
  • 20. new sealed units within existing sashes
  • 21. vacuum DG panes – made in Japan
  • 22. &nbsp;
  • 23. Energy efficient but looks and performs well
  • 24. Thermal properties of Mass Walls
  • 25. Monitoring equipment
  • 26. Castle Fraser – U Value 0.8W/m 2 K for mass walls
  • 27. Lab testing as well CGU Test Chamber 550mm Locharbriggs Calculated U Value 1.4 W/m2K Measured U Value 1.1 W/m2K
  • 28. Scottish winner 2009 Cottage on Skye, U Value 0.6
  • 29. So what to do with a mass wall? Intervene here? Or here?
  • 30. Insulation behind lath and plaster
  • 31. bonded polystyrene bead U value improvement 68%
  • 32. Calcium silicate board
  • 33. Aerogel blanket
  • 34. Aerogel with plaster finish
  • 35. Interior of tenement, Glasgow External wall U-value 1.00
  • 36. breathable insulated board U value improvement 65%
  • 37. cellulose fibre U value improvement 71%
  • 38. Hemp board U value improvement 78%
  • 39. Wood wool with clay board applied as finishing
  • 40. Clay board ready for application of clay plaster
  • 41. External Insulation Maybe not here…
  • 42. But what about here?
  • 43. Wood fibre insulation, Glasgow
  • 44. With 2 coat render system beibng applied
  • 45. Negative visual impact of external insulation
  • 46. Is it worth lifting this?
  • 47. Sheep’s wool pinned to under floor joists
  • 48. Hemp board between joists held in place with timber runners
  • 49. Stone floors – can this be improved?
  • 50. hemp / lime-concrete insulated floor beneath stone flags
  • 51. Concrete floors can be lifted and insulated lime concrete floor laid in its place
  • 52. Lime concrete layer being mixed, laid and flags laid on top
  • 53. Concrete floor insulation: U-value 0.25 W/m 2 .k
  • 54. Should be 250mm thick or more whatever material used
  • 55. Dealing with coombes
  • 56. Sheep’s wool between joists
  • 57. Insulating between rafters using hemp / wool material
  • 58. Door panels can be insulated to reduce heat loss
  • 59. New insulated door to traditional pattern where original has been lost
  • 60. &nbsp;
