The thesis aims to design a device for utilization of waste heat for heating and hot water in NETME Centre in area of FSI VUT in Brno. First of all there is summary of available sources of waste heat and evaluation of serviceability. Next there is design of a device for utilization of waste heat. Design incluades calculation of heat exchangers and selection of particular heat exchangers. It also incluades design of duct system which anables transportation of heated water from heat exchangers to machine room. In machine room is situated storage tank for accumulation of gained waste heat. This storage tank is conected to heating system and to consumption of hot water which anables utilization of waste heat. Finally there is economic evaluation based on amount of gained waste heat, consumption of heat and costs.

The thesis is focused on the economic comparison of heating sources for a particular object in terms of annual operating costs, initial investment costs, payback period, savings over the life of the investment resources and subjective comparisons. At the same time broaden their horizons in terms of obtaining information on technical innovations in the world of heating and an overview of the prices heating and energy sources.

The aim of this diploma thesis is a renovation of a two-story family house in Dolní Krupá. The original house is from 1935. It has several newer outbuildings such as garage or storage spaces. The walls are made of solid fired bricks. There is a timber joist floor structure. The main building has a gable roof with timber roof truss. The outbuildings have flat and mono-pitched roofs. The reason for the renovation is the inefficiency of the aging building combined with nearing end of life of some building elements. Also, the layout of the building with multiple outbuildings built during its service life does not comply with contemporary housing standards. Therefore, a large part of the building will be demolished and replaced with new structures. Only the load-bearing walls on the first floor of the main building and the part of the building adjacent to the garage will remain. The new layout will consist of two separate apartments (one on each floor). The load-bearing structures will include ceramic masonry and reinforced concrete floor. The roof truss will be made of wood. The original appearance of the object will be preserved. The house will be heated with an air-to-water heat pump installed next to the north facade of the house. Each floor of the house will be air conditioned by a separated air conditioning unit. As the third part of the work, I chose a life cycle assessment (LCA), using several different building materials for a this renovation.
