These days , the construction industry is considered one of the most successful and money-making industries. The construction industry is very subject to its own The Performance of Building is very importantprinciples and rules. It is also a term of its own
The material of which a building (and especially its envelope) is made determines the relationship between the outside temperature and the conditions of solar radiation and the internal temperature of buildings without air conditioning. In the case of buildings heated or cooled by a mechanical system. The envelope material is the energy consumed by the system to maintain the internal temperature within the comfort range, as specified in the thermostat setting. determines
Outside temperature and solar radiation follow diurnal cyclical patterns. The outside temperature has a minimum at sunrise, increases and reaches a maximum in the early afternoon and then decreases. It is quantitatively characterized by an average (the range between maximum and minimum) and a certain fluctuation around that average. Solar energy that hits the walls and roof surfaces during the day. It is absorbed, it increases the average temperature inside the building from the average outside space.
While both outdoor temperature and solar radiation patterns are climatic factors beyond the architect’s control, there is a major difference between them in terms of the controllability of their effect on indoor temperature and energy consumption by mechanical thermal control systems. By using design details, it is much easier to control the effect of solar radiation than the temperature conditions outside.
