All buildings are not the same .Neither are they located in a particular single geographical region. Their needs too may differ, for example whether it’s heating or cooling that you require or whether it’s both. (In which case which requirement prevails longer).The following information gives a better idea to plan this out.
• Climate prevailing at the site
• Space temperature you would be happy with.(low temperature setting will cause lesser loss of heat)
• Suitability, acceptability (by local regulations etc) and the convenience to insulate.
• Life span and durability (some are susceptible to moisture, material may settle soon and loose profile, may deteriorate faster etc.)
• Mode of heat transfer (whether conduction , convection or radiation is prevailing more)
• Building architectural design, orientation, use of glass in the building envelope etc. (for example whether outsulation is possible, air tightness, vapour permeability, forced or passive ventilation, possibility to use low-e insulated glass etc).
• Toxicity of the material (short term or long term)
• Sustainability, Carbon foot print, environmental friendliness and ability to recycle.
