Determination of Energy Characteristic of Buildings
Abstract
Mathematical model of solar radiation availability and thermal conversion of solar energy in a building envelope has been developed. Numerical simulation based on the developed mathematical model has been used to determine energy characteristics of a building. The developed model allows many cases of a building structure to be analysed. In the paper energy characteristics of some room cases are presented. The rooms selected for consideration are especially highly irradiated in summer what causes relatively high cooling demand. The paper considers also heat transfer through opaque elements of a building envelope. Examples of two different coating materials that differ mainly in solar absorptance are presented. Incorporation of Phase Change Materials into building structure is also mentioned.
