Building floor on the ground is one of its partitions with exterior, which performs many functions. Floors on the ground separate building interior from the ground. They are also protected against the transfer of heat to soil or outside. This protection is performed by forming thermal insulating layer. For floor thermal insulation usually we used same materials as the rest of building insulation. In this work I will review the requirements for newly built buildings from 2018 buildings being built since 2018 have to be low or almost nearly zero energy using buildings. To achieve this, it is necessary to insulate the external partitions so well that we need to use as little energy to heat building as possible. The A++ class public building floors on the ground is examined. I take tree commonly used building shapes; square, rectangular and C shape. Every of these tree building shapes will be calculated based on tree thermal insulating materials: polystyrene foam, extruded polystyrene foam and rock wool. Each of the optimal insulating options and generally optimal insulating material and the shape of the building are determined using TOPSIS Multi-Criteria evaluation method. The criteria according to which I will calculate the optimal variant, I have chosen at my one discretion, according to the available knowledge, what should be considered when choosing the insulation method. A survey was made and interviewed people evaluate my chosen criteria according to their consideration. Selected criteria: insulation thickness, thermal conductivity coefficient, installation cost €/1m2, compressive strength, and thermal insulation cost. In the study, it was found that the most optimal is used extruded polystyrene foam, the almost equivalent option is polystyrene foam and rock wool is the worst alternative. Due to the shape of the building, the best option is to have square building. The large is building perimeter compare to the area of it, we need to insulate building more and more. |
