Resulting in:v Increase in temperature inside the Buildings
v .Inside Temperature is likely to go above than the Outside Ambient
v Higher Air Conditioning Loads and increased running time of the Compressors

n Building energy efficiency includes two parts: envelop (insulation for roof, external wall, window, door and ground floor) and maintenance (energy efficiency improvement for lighting, air conditioner, water heater, green power acquirement such as solar power and wind power etc.).
n The role of thermal insulation is to improve Building Envelope's Energy efficiency.
IMPORTANCE OF THERMAL INSULATION
IN BUILDINGS
`
3
Thermal Insulation is an essential part of all Buildings and performs many functions.
Energy Conservation – Reduces the heating / cooling load
Human Comfort – improves the efficiency of the workmen
`
THERMAL INSULATION
Human Comfort in buildings depends, of course upon the proper design of Heating / Cooling equipment.
Efficient operation of these equipment however depends on the effectiveness of the Thermal Insulation.

THERMAL INSULATION
The Design of Insulation requirements for buildings is not straight forward as the calculation of economic thickness for pipeline / equipment
Almost all Building material provide some resistance to heat flow and thermal insulation is a part of the system
Hence the design solution for the thermal insulation of buildings must be based on comparison of the system
`
THERMAL INSULATION
Ø Location and Weather conditions
Ø Orientation of the building
Ø Wind / breeze
Ø Height of Ceiling
`
THERMAL INSULATION
Factors influencing the design of insulation of building
Factors influencing the design of insulation of building
Ø Proportion of Glassed Areas, Door / Window / Ventilator openings
Ø Shading
Ø Whether the building is only heated or heated or cooled
`
THERMAL INSULATION

Because of the above factors, The
Thermal Conductance given by “U”
value forms the basis for design and
becomes the only governing factor for
selection of insulating mater ial
`
THERMAL INSULATION
Thermal Conductance “U” is
defined as the reciprocal of the
total thermal resistance
U = 1/R
`
THERMAL INSULATION
Thermal resistance R is given by
R = 1/fo + 1/fi + l/k
Where
fo –Outside surface conductancefi – Inside surface conductancel –Thickness of materialK – thermal Conductivity of the material
