“…century, but this does not mean that humanity did not previously use different materials for thermal insulation. However, with the development of the industry, the development of thermal insulation materials has arisen [3,4]. With the development of I4.0, the development of thermal insulation materials has also become an important point.…”

The main purpose of this paper is to present the use of super thermal insulation materials for a historical building through a calculation-based case study. The development of the insulation materials is based on the objective of making buildings as energy efficient as possible, and the energy loss should be kept to a minimum, for both new and existing buildings. For this purpose, the thermal insulation materials used so far have not always achieved maximum effectiveness. In the case of historical buildings, it is particularly difficult to solve insulation issues, as the building cannot lose its former appearance. However, aerogel and vacuum insulation panels can also be used as thin thermal protective layers. In this paper, we will specifically deal with the presentation of the possible application of super thermal insulation materials, such as vacuum insulation panels and aerogels. We will present thermal conductivity measurement results as well as their application through building energetic calculations applied to a historical building as a case study. We will also present certain calculations regarding the costs. The paper highlights that savings of energy costs of approximately 30% can be reached using vacuum insulation sandwich panels. Furthermore, the overall thermal transmittance of the building also decreases by about 35% if vacuum insulation sandwich panels are used for the refurbishment.

In the European Union, almost 40% of all energy consumption comes from buildings, while another 20–25% comes from transport. In the European Union, including Hungary, only buildings with almost-zero energy demand could be built after 2020, and the use of renewable energies must be strengthened. The Renewable Directive stipulated that by 2020, the share of renewable energy in buildings must be 25%, and in transport it must be 10%; the use of electric vehicles is vital. There are about four million dwellings in Hungary, of which approximately three million need to be renovated, and only some 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. To reduce the energy loss from buildings, different insulation materials can be used; investigations of insulation materials are very important. This paper presents a comprehensive research report on insulation materials which could be used for building elements, HVAC (heating, ventilation, and air conditioning appliances) equipment, and vehicles. In this paper, laboratory investigations will be presented along with calculations to better understand the properties and behavior of these materials. For this, firstly structural analysis with scanning electron microscope will be presented. Moreover, the paper will present thermal conductivity and combustion heat measurement results. The sorption and hydrophobic behavior of the materials will be also revealed. Finally, the article will also display differential scanning calorimetry measurements and Raman spectroscopy results of the samples. The research was conducted on four different types of colorized microfiber lightweight wool insulation.
