Special Issue Information

Dear Colleagues,

A Special Issue entitled “Advanced Building Materials for Energy Saving” will deal with new solutions in technology of building materials, which contribute to a reduction in energy consumption. More and more often, the use of low-processed materials with low built-in energy is considered. The reduction in energy consumption in the production of building materials is achieved, for example, using raw materials of plant origin, industrial waste or recycled materials. In addition to the production of building material, energy is used for heating purposes in buildings in the use phase. The key here is the development of materials with good thermal parameters, such as low thermal conductivity and high heat capacity. These will make it possible to reduce the energy demand for heating during the heating season. The processes of utilization of building materials are also energy intensive. The energy consumption of this process can be reduced by materials that can be recycled or by biodegradable materials. Original articles and reviews of building materials, both of natural and synthetic origin, which can contribute to a reduction in energy consumption in the production phase, in the use phase of the building, and in the end of life phase are welcome.

The junction between the roof and the external wall is a sensitive area within the building envelope; here, increased heat flow often takes place. In the case of partitions insulated with materials based on plant ingredients, thermal bridges are particularly dangerous due to the possibility of condensation and, consequently, mold. The present article analyzed the connection of the roof with the knee wall made of a hemp–lime composite and the ridge in terms of the occurrence of thermal bridges. The following factors that may affect heat transfer in the junction were taken into account: the location of the load-bearing wooden frame, the roof slope, and the presence of internal plaster in the junction. Two-dimensional heat transfer analysis was performed based on the finite element method using THERM 7.4 software. All of the studied thermal bridges had ψ values below 0.10 W/(m·K). Calculations of heat losses through a roof with different slopes were also presented, taking into account the considered thermal bridges. As the roof slope decreases, the heat flow through the roof decreases, despite the increasing value of the linear thermal transmittance. The share of the considered thermal bridges in the total heat loss from the roof reached up to 15%. To verify the obtained results, in further analysis, it would be necessary to calculate the impact of the roof–knee wall bridge variants on heat losses throughout the entire building. Full article
