“…Zhang et al [71] investigated the insulation performance of the external envelops by studying the effects of building external wall's insulation thickness and position on the heating and cooling loads of a commercial building for five cities from different climatic zones of China numerically. To retrofit the building, a method based on the whole building's thermal analysis specifically for cooling demand countries was developed by Nazi et al [72] to find the effective strategies for retrofitting and modeling to predict energy reduction.…”

“…High energy consumptions in the building sector (about 32% of total global final energy use), addressed for a share of 34% to space heating [1], are pushing research activities in finding the best solution to avoid, shift and reduce heat waves or losses [2][3][4][5][6].…”

The addition of insulating layers on vertical walls of buildings is a common practice for providing a higher thermal insulation of the envelope. Workmanship defects, however, might influence the effectiveness of such insulation strategy. Damaged materials, incorrect installation, use of aged or weathered materials might alter the capability of reducing heat transfer through the envelope, whether vertical or sloped. In this work, drawbacks caused by the wrong installation of insulating material and by damaged material are assessed. A specimen wall was investigated by experimental and numerical approaches, the latter carried out by using COMSOL Multiphysics®. Results are compared and discussed.

“…Thermal comfort analysis of LIG house using CFD is reported in [21], it is reported that varying the sizes of windows do not improve the thermal comfort of house. Energy requirement of building is studied in [22] and revealed that providing a insulating material on building walls and roof reduces the energy requirement of building Many researchers [23][24][25] have studied the effect of thermo physical properties of material and wall thickness on time lag and decrement factor, however none of the papers have reported the effect of time lag and decrement factor for estimating room temperature of house. In present paper semi empirical method has been used for thermal performance analysis of LIG (Low Income Group) house located at Raipur, India.…”

Raipur, capital of Chhattisgarh state, India, is located at (21.18° N and 81.78° E). During summer season, the city experiences maximum temperature of 46 ºC. Residents resort to external cooling sources almost throughout the year for achieving thermal comfort. Therefore, thermal performance analysis of house is important to assess the temperature inside the house at different season. In present work, mathematical model of hourly temperature distribution in each room of the Low Income Group (LIG) house has been developed using time lag and decrement factor. A system of differential equations is derived and solved. The results obtained are validated with data collected onsite. The study is reported for three major seasons realized in Raipur. Deviation of room temperature from predefined thermal comfort has been calculated and reported for different season. The report reveals the lack of thermal comfort from the sets standards in post-monsoon and summer season.
