In architecture science thermal comfort in buildings can be achieved by heat transfer mechanisms , which are conduction where by heat energy is transferred between bodies in direct contact .
Secondly heat can be transferred through convection where heat moves through liquid or gas molecule mediums . Radiation is also identified as a heat transfer mechanism because heat energy is transmitted as electromagnetic waves and finally evaporation, heat in this mechanism is transferred through water vapor where by heat is lost to the atmosphere through vapor.
The are factors that affect thermal sensation which are air temperature, humidity, air velocity, mean radiant temperature, clothing levels and metabolic rate (Fanger thermal equtions 2001).
The art of achieving thermal comfort in architecture is supported by scientific theories but it is still art. The art of finishes put on the building can be meant to absorb or reflect heat.
The art of building materials choice used can be constructed to keep or loose heat, and the art of orienting the building can allow radiation from the sun or any heat source in or out of the building.
Generally thermal comfort can be achieved only with scientific means but it is the art of the architect to design for more or less thermal comfort and how long should it last.
