Analysis and design of heat resistant building through structures

The building envelope is subjected to climatic influences by its individual orientation and composition. The main function of the building envelope in hot climates is to minimize external heat stress. Indoor thermal control can only be achieved through understanding of the thermal performance of the building envelope in relation to relevant weather parameters. It is also becoming increasingly realized that much can be done to mitigate heat stress in unconditioned buildings and to reduce cooling and heating loads and the energy consumption of air conditioned buildings, through a proper choice of building envelope materials and envelope design. The envelope's response to climatic conditions is a major determinant of the amount of energy required to maintain the building's thermal environment. Also, he building envelope directly influences the cooling peaks and air conditioning system capacity requirements. The thermal properties of the envelope are determined by the combination of wall mass, thermal resistance; insulation location, external surface colour, texture, and size.

Heating, ventilation and air conditioning (HVAC) systems in buildings aim to control the indoor climate in order to keep occupants comfortable by control the temperature and air flow. To achieve this purpose, it is necessary to have adaptable control systems that could deal with the parameters required to control the indoor climatic conditions. There are for this purpose computer models that could simulate indoor climatic processes and how to control their parameters. The success of the modeling process depends on the ability to deal with changing conditions and respond effectively as much as possible so as to maintain the necessary conditions for comfort of the occupants taking into account the cost. In this paper a thermal model for a residential room has been developed using Simulink/MATLAB trying to deal mainly with the issue of maintaining the desired indoor temperature in spite of the change in outdoor conditions.
