Abstract

In the European Union, almost 40% of all energy consumption arises from buildings, while another nearly 20-25% comes from transport. In the European Union, including Hungary, only buildings with almost zero energy demand can be built after 2020, and the use of renewable energies must be strengthened. The Renewable Directive stipulates that by 2020, the share of renewable energy in buildings must be 25% and in transport 10%. There are about four million dwellings in Hungary, of which approximately 3 million need to be renovated, and only a few of these (a few hundred) meet the cost-optimized level of the 2020 directive. The use of insulation materials is very important in the transport sector, too. Insulation materials are also used by aircraft and electric vehicles. Therefore, there is a need for using suitable thermal insulation management components that can minimize cooling and heating energy loss within the vehicle and building interiors. Since the investigations executed on insulation materials are very important. In the paper, we will present laboratory investigations and calculations to better understand the properties and behaviour of the nanostructured materials e.g.: vacuum insulation panels, advanced porous materials, or graphite doped polystyrene. The paper will present a comprehensive comparison of the thermal conductivities of different insulation materials reached by both heat flow meter and guarded hot box method.
