Heat transfer assessment of straw bale walled room

Abstract

This research work explores the thermal performance of straw bale walled building (of 0.14 W/m2K) in holistic sense, with concepts that determines the interrelation of internal and external heat gain and loss, building envelope performance, the thermal demand of occupant and the balance point. The calculation result has shown that an outdoor temperature of 17OC will balance the internal heat gain to produce a comfortable temperature of 24.5OC inside the room Considering the solar heat gain of 78.2 W/m2 at the wall surface area, the amount of balance point required has shown the insulation efficiency of the strawbale masonry with a constant temperature inside the room with time variation.
