HEAT EXCHANGE AND U-VALUE
Passive design
Architectural design
Building Configuration
Material choices
Thermal Resistivity
:
Time required for one unit of heat
Thickness
Unit mK/A
Thermal Resistance
Transfer of heat from a surface of body
Reciprocal of Thermal conductance
Unit R=b/K
Thermal Conductivity
Quality of heat transmitted
Property of material to conduct heat
Unit W/mK
AND U-VALUE
Thermal Conductance
Thickness of material
Unit W/m^2K
Factors
Temperature
Time
Area
Thickness
Building Purpose
Provide Shelter
Privacy
Security
Thermal Comfort
U-Value
Heat transmission between interior and exterior
Lower the U-value better the insulation
Materials with low U-value or insulators can be used to decrease U-value
Factors
Thermal resistivity
Thermal conductance (Thickness of the material)
Thermal Conductivity: Transmission of heat in steady condition through unit area and unit thickness of material in unit time when temperature difference exists between the opposite surface.
