Optimization of Design of Pitched Roofs According to Phase Shift of Thermal Oscillation

Abstract:

It is important to take into account some more parameters, e.g. heat transfer coefficient, hygienic criterion or globalised energetic criterion, nowadays. It is a time when there is a big emphasize on thermal protection of residential buildings. Therefore an important calculation parameter is spoken more often - temperature loss and phase shift of thermal oscillation. This two parameters are very important especially in case of building envelopes based on lightweight supporting and used insulation materials. A pitched roof in residential building or family house is a typical example. This problem is growing even more, if we are taking adverse ratio of outer surface to volume of the space into account. This paper is showing analysis of such building envelope construction, its designing and influence on optimal values of phase shift of thermal oscillation.
