Abstract

The Institute of Architectural Engineering at the Civil Engineering Faculty TU of Kosice, in its ongoing research, aims to monitor the physical properties of building envelope structures with emphasis placed on hydrothermal problems, at present. The research focuses on the assembly of equipment in climate chambers with their respective sample envelopes and fenestration systems, which are involved in a measuring experiment. The prime aim is to design a logical and transparent system for gathering, evaluating and storing hydrothermal related data. This contribution further illustrates the embedding system of measurement points in installed samples and the system of monitoring their physical properties over an annual period.

Abstract

Not for nothing it is said that "a good roof is priceless." Although it may lead to discussions, which roof is good, because there are a lot of requirements and criteria for the functional characterization. It must be understood that the roof structure defines the durability of the building as a unit, therefore it defines lifetime of other parts of the building and also the function of space that is covered by the roof. Therefore it is very important to pay particular attention to the design, as well as the realization of the roof structure. The aim of this publication is to judge the physical and technical parameters in the design of the roof coating module in a climatic chamber.

Abstract

In countries of the European Union, the proportion of buildings in the overall energy consumption represents 40% and their proportion in CO2 emissions 35%. Taking into account dependence of the European Union on import of energy, this represents large quantity of energy and CO2 emissions, in spite of the fact that there exist effective solutions for reduction of building energy demand. In Directive 20-20-20, the European Union adopted three main commitments of fulfillment criteria by 2020. On the basis of this directive, the Slovak Republic declares support of renovation of apartment dwelling houses. Taking into account the fact that state subsidy can be obtained only once, and energy requirements of the European Union are increasingly stricter, a comprehensive approach to renovation of buildings is inevitable. At the same time, it is inevitable to propose the renovation of buildings taking into account requirements stated for buildings for year 2020. Two areas were compared within the case study taking into account primary energy and the quantity of CO2 emissions. Both areas have the same built-up area, but one of them is a district city and the second is a suburb. From results it is obvious that the quantity of primary energy is lower by 88% in the district city than in the suburb. The quantity of CO2 emissions is lower by 69% in the district city than in the suburb.
