The project in five facts.
Challenge, approach and results.
In the diploma thesis, the author described the standard and characteristics of a passive house and what is important in its design. The characteristics and construction technology of a brick-built house and a prefabricated house made of sandwich panels are described. The basic assertion that was put forward at the beginning of the diploma thesis, that a passive masonry house is more cost-effective and accessible than a passive prefabricated house, was thus confirmed through comparative analysis and proven to be correct.
Solution and Method
In the diploma thesis, the author described the standard and characteristics of a passive house and what is important in its design. The characteristics and construction technology of a brick-built house and a prefabricated house made of sandwich panels are described. He produced a comparative analysis between both types of construction based on the project for obtaining a building permit and implementation. The comparative analysis was carried out for characteristics, construction time and construction cost.
The cost analysis was carried out for construction up to the 4th construction phase, which includes all costs for external completion of the house and implementation of internal wall treatment, whereby finalisation costs were not taken into account, as these are the same for both types of construction (mechanical and electrical installations, floors, renders, floor and wall coverings, internal joinery, etc.). Likewise, the foundations of the brick-built house and the prefabricated house made of sandwich panels are identical in both cases, namely with a reinforced concrete foundation slab.
The time-schedule, cost and comparative analysis was carried out on the basis of two obtained quotations for each type of construction. The construction of a passive brick-built house represents significantly greater engagement for the investor than the construction of a passive prefabricated house made of timber panels. Manufacturers of prefabricated houses must have certified production, whilst their installers and contractors carrying out trades work must have experience with the construction of passive houses.
Manufacturers are also skilled in preparing documentation for obtaining Eko sklad subsidies. The statements in this paragraph only apply if the investor orders the implementation of the house from the manufacturer up to complete completion. It is important that the investor of a brick-built house selects a supervisor who has references for passive construction.
It is also important that the investor selects a contractor who has references for passive construction, and that they order the implementation of the house up to complete completion. Any partial implementation of a passive house, whether masonry or prefabricated, means great engagement by the investor and the possibility of many errors. Such phased implementations can only be undertaken by those investors who are professionals in the construction trade and for whom construction represents a challenge.
The characteristic comparative analysis describes the advantages and disadvantages of both types of construction, on the basis of which the investor will find it easier to decide when selecting the type of construction. The time-schedule comparative analysis states the implementation deadlines of all suppliers, from which we can discern that the implementation deadlines for both types of construction are similar, so this analysis does not influence the investor's decision when selecting the type of construction. The cost comparative analysis states the prices of all suppliers, and from it it is evident that the construction of a brick-built house is considerably cheaper than the construction of a prefabricated house made of sandwich panels.
A passive house is the house of the future – regardless of what type of construction it is, even though this will undergo quite a few changes in the future. Given the climate changes, which are associated with increasingly hot summer periods, appropriate phase shift is one of the most important characteristics of any building, whether residential or commercial, regardless of construction technology. Appropriate phase shift enables comfortable living in the summer period, as it prevents the penetration of external heat into the building, which is associated with lower costs for cooling the building.
Phase shift is not yet receiving sufficient attention today, but this will change in the near future. However, it is true that thermal insulation materials with greater phase shifts are considerably more expensive than others. Achieving the airtightness of a building according to passive house criteria is not an easily solvable problem, for both masonry and prefabricated buildings.
In both construction technologies, achieving airtightness is associated with knowledge of the issues and the method of implementation of certain details, the implementation of which is of key importance for achieving airtightness.

The basic assertion that was put forward at the beginning of the diploma thesis, that a passive masonry house is more cost-effective and accessible than a passive prefabricated house, was thus confirmed through comparative analysis and proven to be correct.
