The diploma thesis deals with the solutions of the renovation of a panel apartment building with regard to energy efficiency. The theoretical part deals with heat pumps. The acquired knowledge was subsequently applied in the computational part, where the energy assessment of the current state of the apartment building and the design of two possible variants of renovation are addressed. The aim of the first variant is the renovation of the building to meet classification class C using the possible funds. The second variant is focused on the technical equipment of the building and primary energy from renewable sources, so that the apartment building reaches classification class A. Both proposed variants are assessed from both an energy and financial point of view. The project part then contains certificates of energy intensity of individual variants of the building.

The subject of the diploma thesis is a preparation of a prefabricated hall with administration in Prace. The production hall will be used to produce glass fiber reinforced concrete. Next part and extension is an administrative part. The text part of the thesis contains a technical report on the building technological project, time and financial plan of the building - object, coordinating situation of the building with broader relations of the transport routes, study of the realization of the main technological stages of the building object, item budget of the main building object, time schedule of the main building, sets of the main technological stages, detection protocols for individual months, limits, balance of resources and personnel, plan of selected material sources, technical report of construction site equipment, technological regulation of precast reinforced concrete frame, technological regulation of precast concrete frame coverings Kingspan panels, Control and test plan of precast concrete frame, covering of precast concrete frame panels Kingspan and ceiling panels of the Spiroll administration, alternative suggestion of the exchange ceiling construction administration and comparison, noise study and thermal technology.

The final thesis is focused od the experimental metods in energy rating of building. In the first part is described history of energy rating from the eigtheens to the present and described is the current trend of energy rating in terms of energy performance certificates. In the second part is elaborated energy assessment for apartment building from bricks with six residential units. For the building is drawn a total of 6 measures, of which there are 3 structural and 3 for building equipment. The measures are assembled to variants and the resulting variant is recommended, including recommendation. In the last experimental part is described the influence of shading elements on the thermal load of the room and modeled the effect of insulating double glazing and triple the overall energy performance reference room.
