Possibilities of energy savings in the residential house Merhautova

The diploma thesis is about the reduction of the energy intensity of the existing residential house Merhautova. The design documentation is focused on the thermal insulation of the living area, the replacement of windows and doors according to the variant of the design, accessible entrance to the house, loggia on the south side of the building and the replacement of the roofing. At the beginning of the diploma thesis the experimental part of the thermography was performed. Images of the existing object by the thermal camera were taken and building survey for the design documentation of the current state of the building was performed. Within the theoretical calculations the energy performance certificate was processed in options of the entering the thermal bridges. The energy performance certificate with thermal bridges calculated according to the details was compared with the energy performance certificate with estimated thermal bridges. A comparison of two options of the replacement of windows and doors was made in realation of the energy intesity of the building. A preliminary budget of these two options was also calculated with regard to the expected simple return on investment due to the heat saving
