Abstract text:
Energy performance of buildings is directly influenced by building envelope efficiency, that is on its turn affected by thermal bridging. World wide there are different appliances used for assessment of energy performance of buildings, that take into consideration thermal bridge effect by different degrees of accuracy, in order to obtain more realistic results. This paper presents a detailed analysis of Energy Performance of Building Directive integration in Romanian National Building Codes and Legislation, with regards to thermal bridging. Furthermore, there are described study possibilities of heat and mass transfer by means of numerical simulation tools. Analysing the influence of using these numerical programs in thermal bridge assessment, and its share in the final results for energy efficiency, allows us to lay down some useful conclusions concerning the building energy certification and regulation activity and in pointing out future research directions.
Key Words:
energy performance of buildings (EPBD); energy efficiency; thermal bridge; numerical simulation tools.
