Concepts of remedial treatments of historic buildings using ventilated floors, with a few exceptions, are with considerable popularity preferred by the representatives of monument protection. The fact that they require small interventions in the masonry is of great benefit for compliance with the methodology of cultural heritage protection, as is the fact that such interventions do not compromise the structural analysis of buildings. These concepts have gained great popularity also because they can be considered kind of a "return" to historical example. With these technologies we return to the methods and principles that the ancient Egyptians were already familiar with. The paradox is that these methods are used for many centuries, until today they are only proposed on the basis of empiricism. There is no proven relationship and calculation nor any literature that would address the airflow in floors, ventilation ducts and galleries around the base building construction. The remaining problem is the draft of air cavities in general. The exact calculation of airflow in the underfloor cavity has not yet been formulated. To assessment the airflow in the air cavity the recently often used CFD simulations can be employed. Using simulation, respective design cycles, which shall be ultimately verified by laboratory experiments and also by in situ measurements, may be accelerated.

The quality of most buildings may be affected during the initial phase of architectural design. Therefore, it is important to optimize input parameters, which significantly influence energy efficiency. In principle, it is possible to speak of a deterministic approach, which considers input parameters to be fixed, or a stochastic approach, which takes a wider set of input parameters into account. A reference building is evaluated in terms of energy performance, where input parameters are changed in order to determine a correlation coefficient. Regressions were written to express the impact architectural design has on energy performance.

In accordance with long-term strategic objectives of reducing emissions and improving energy efficiency, adoption of the European Parliament on May 18, 2010 and the adoption of 2010/31/EU raised the commitment by 2020 to reduce total greenhouse gas emissions by et least 20%. The Directive requires Member state to design all new buildings with nearly zero until December 31 2020. Aims of Directive can be applied in conjunction excellent thermal parameters of buildings envelope design energy-efficient buildings and shape solutions. For optimal design EEB has a major impact outside geometry, i.e. compact of shape and surface topography. After construction of the EEB is a possible number of parameters to modify, but the shape that has been proposed in the early stage of architectural design usually remains unchanged throughout the life of building. This paper provides analysis of building shape (ground plan and vertical division) and their impact of shape factor FT of buildings. For some shape is provide a parametric analysis obtained from a comprehensive whole building energy simulation. Parametric analysis regards orientation of buildings to the cardinal point and ratio of glazing to the building envelope wall.

We have more kinds of congregation rooms. When building of these spaces must to supervise, among other the requirements also the quality of the indoor air should be considered. In our article we are engaged analysis of ventilation in church of the 13th century. The aim is analyzing of produce of pollutant emissions from persons in the room. One of measurable the pollutant is carbon dioxide, which is produced by persons. Beside the respiration, the person produces other pollutants, such as odor and others. On the basis of experimental measurements the concentration of carbon dioxide produced by person, currently we know calculate how much air exchange is required for the room. The concentration of carbon dioxide has be smaller how 1,000 ppm and maximum up to 1,500 ppm. Already above the value of 1,000 ppm causes to decrease the concentration to perception for people. The aim of the paper is to determine the methodology for calculating the intensity of ventilation rate in the room. It is need to maintain the required air quality. Calculated ventilation rate should optimize investment and operating costs of ventilation equipment. In the work there is carried out analysis of calculation methods to determine the ventilation rate. It is processed the methodology for calculating the ventilation rate of room, there are used the measured values of concentrations of carbon dioxide. Values of concentrations of carbon dioxide and ventilation rate there are verified by experimental measurements. The methodology is selected for calculating ventilation rate applicable in to Slovakia.

Budowanych jest coraz więcej kościołów parafialnych. Wznosząc te obiekty należy przestrzegać wymogi dotyczące jakość powietrza wewnątrz nich. W artykule zajęto się analizą wentylacji w kościele z XIII wieku. Celem analizy była emisja zanieczyszczeń powodowana przez osoby będące w kościele. Jednym z mierzonych zanieczyszczeń był dwutlenek węgla wydychany przez osoby. Obok oddychania, osoba produkuje inne zanieczyszczenia, jak np. zapach. Na podstawie pomiarów doświadczalny poznano stężenie dwutlenku węgla wytwarzanego przez osobę, i jest znana konieczna objętość wymiany powietrza w kościele. Stężenie dwutlenku węgla powinna być mniejszym niż 1,000 ppm, a maksymalna do 1,500 ppm., ponieważ ponad wartością z 1,000 ppm skutkuje zmniejszenie koncentracji. Celem artykułu jest ustalenie metodologii dla obliczania intensywności wentylacji pomieszczenia, do uzyskania wymaganego stopnia czystości powietrza. Oszacowany wskaźnik wentylacji powinien optymalizować inwestycję i koszty eksploatacyjne wentylacji. Przedstawiono również analizę metod obliczania wskaźnika wentylacji dopasowanego do warunków obowiązujących na Słowacji.

Integrated building design should take into account environmental, social and economic dimensions of sustainability. Building design from energy performance ranges from architectural design to the application of technologies for energy conservation. Many applications are focused on insulation of facades, roofs and floors to those that are used systems for renewable energy sources. The aim of the innovations is not only energy saving but also reduces costs and preserves natural resources. One key element of low-energy building design is using the basic form and enclosure of a building to save energy while enhancing occupant comfort. Besides energy need for building operation the significant part of the total energy is energy used in the extraction, processing and transportation of materials used in buildings. This study is aimed to analyze the building materials and structures in terms of embodied environmental impacts and monitoring of physical factors of indoor environment. The paper deals with evaluation of environmental and energy indicators in selected low-energy family house and its optimization in order to reduction of environmental impacts.

External constructions of buildings provide their protection from external influences. These constructions ought to create optimal comfort of interior environment in winter as well as in summer. It has been shown in practice that the largest number of breakdowns occurs in external constructions. The external constructions of walls, roofs and floors too present a big area of problems in design of new and reconstructed buildings respectively. Heat losses of buildings through external constructions - roof, external walls, floor on the ground - are not negligible. It is therefore important to pay more attention to these constructions. Basementless buildings stepped directly on the ground are in direct interaction with subgrade and its thermal state. An amount of heat primarily destined for creation of thermal comfort in the interior escapes from foundational construction and floor on the ground to the cooler subgrade. The outgoing heat represents heat losses, which unfavourably affect the overall energetic effectiveness of the building. The heat losses represent approximately 15 to 20% of the overall heat losses of the building. This number is a clear antecedent of need for isolation and minimalization of heat flow from the building to the subgrade.
