An effort has been made to combine the non-periodic transient heat flow due to instantaneous rise in outdoor temperature with periodic heat flow. The study becomes useful to predict thermal performance of building section during heat wave in summer and snow fall in winter season. In order to solve non-periodic heat flow problem, transcendental equation is required to be solved. Approximate values of unknown roots of transcendental equation for different ranges of Biot number have been given for reference. The solution has been combined along with the periodic heat flow. The response factor and temperature distribution in single and multilayered building section have also been determined.</span>
