Comparative analysis of current standards for testing thermal protection of facade carpentry

Abstract

The low level of energy efficiency in buildings results in increased energy consumption for heating and cooling and high carbon dioxide emissions. Insufficient thermal protection of the exterior of a building contributes to a high value of thermal transmittance of external walls and facade carpentry. Regulations and standards in the field of energy efficiency in Serbia are going to be harmonized with European documents, which is an integral part of the EU accession process. Before placing construction products on the market, it is necessary to examine product performances of products so that the thermal transmittance of facade carpentry can be tested according two valid Serbian standards: SRPS U.J5. 060 from 1984 and SRPS EN ISO 12567-1, which were adopted in 2012. These types of testing can only be performed in accredited laboratories. The paper presents a comparative analysis of those two standards for testing thermal transmittance of external carpentry, the testing method, measuring equipment, the obtaining of results that prove the performance of the product.
