The paper deals with the comparison of real energy consumption with values calculated in the Energy Performance Certificate (PENB) for two buildings: New low-energy family house and older apartment building. In both cases, these are wooden buildings. Subsequently, basic differences between the card and the reality in terms of energy consumption are defined in the form of house use coefficients.

The article deals with BIM technology in co-operation with design of HVAC. The theme is divided into two related parts. The first part describes the complex issues related to BIM technology and its implementation in TZB practice. In the second part there is a practical way of comparing the calculation of heat losses according to CSN EN and using the BIM tool.

The standard is used to calculate water heaters and to evaluate the energy of hot water systems. It is one of the basic standards for designers of sanitary installations and heating.

The paper presents results of a study on potential reduction of CO₂ emissions of the Czech national building stock until 2075. The calculations were based on datasets provided by Chance for Buildings that modeled five different scenarios of energy savings in the Czech building stock that varied by the depth of the energy retrofitting measures and by the pace of their application. The results were compared to the carbon budget that was set in line with the objectives of the Paris agreement.

The study deals with the measurement of microclimatic (indoor climatic) parameters and questionnaire survey in open-space offices. It describes the building, the air conditioning system and the parameters that have been assessed in the space. The paper shows the problems associated with the assessment of the thermal-humidity microclimate according to the subjective feelings of the occupants. It is an introductory work to the analysis of objective and subjective assessment in the space with uneven thermal-humidity microclimate.

The paper is focused on the evaluation of the possibilities using the diagnosis of building objects and outcomes of the mobile 3D scanning process of existing objects and their software transformation using Building Information Modeling (BIM). Emphasis is placed on the creation of building object based on the point cloud determined by 3D mobile mapping. The main objective was to process measured data from mobile mapping, import data into the Autodesk Revit program and create a BIM model. A partial objective was to compare the resulting object originating from the point cloud to the existing project documentation. Conclusion of the paper is evaluating the process through SWOT analysis.

The article describes the characteristics of individual types of fixed fire extinguishing systems and shows why sprinkler protection is considered dominant in the fire protection of non-productive buildings.

Feeling safe affects our daily lives, is one of the basic human needs and affects the quality of life. Security is a seemingly clear and simple field. But the question is how to distinguish the quality offered from fraudulent pretense?

The current trend of research is concerned with the multi-compartment fire dynamics – the dynamics of a fire which spreads through multiple rooms, such as a house or multiple-room flat. It is based on the results obtained from the one room fire dynamics researches, but in dealing with this cases much more variables need to be considered. This complicated process facilitates mathematical modeling and tests fires in laboratories. We bring some integrated outputs that will surely be useful for practice.

Determining a location of the fire origin is an important and integral part of the process of the fire investigation. Any new information, experience, research or method represents an improvement in this complicated area. With this knowledge, fire investigators can more confidently interpret conclusions of their work. Fire dynamic also helps them with a better understanding of fire effect and assistance them with evaluating fire patterns in affected rooms of buildings.

Compartment fires are among the most frequent and also the most dangerous ones. Accordingly, we pay special attention to these fires in terms of fire tactics. In the Czech Republic, several facilities have been created to simulate fire conditions in enclosed spaces (“flashover containers”) and the firefighters have the opportunity to prepare for potential hazards. However, can this type of fires be special in terms of fire investigations?

Building Information Modeling (BIM) is being developed in almost all construction sectors in the Czech Republic. For Quantity Takeoff (part of Cost Management, referred to as BIM 5D), this brings many opportunities and challenges associated with the need of local workflows modification in accordance to information modeling needs. This article describes how data from BIM models can be used today to cost estimates using the proposed process scheme. It also indicates what needs to be done to achieve the full utilization of the BIM method in terms of cost estimation.

BIM processes have brought to the design process improvement in co-ordination between different professions and, in the case of the statics profession, facilitating the creation of a load-bearing structure model. The duplicate work was removed, where the same structural elements had to be modeled by two offices, both architectural and static. In addition, these models are now interconnected and coordinated. In this article, we will present the entire process on a project of the load-bearing structure of a set of apartment buildings with a common underground floor. It is designed on the basis of current European standards using BIM processes for its design and drawing documentation.

Facility management contributes to the smooth running of the organization's core business, helping to create a quality work environment for workers, a prerequisite for increasing performance, improving work quality, reducing health outcomes and stress factors.

The removal of heat and combustion products in the underground garage of the commercial and entertainment center was solved by the smoke clearing system. In the garage, vacuum ventilation was considered. The difference between the exhaust and the intake air was 20%.

Measuring and control devices as well as other HVAC systems, run through their lifecycle, at the end of which the system needs to be reconstructed. A key condition for a successful retrofit is to determine the required life of the refurbished equipment.

Facility management contributes to the smooth running of the organization's core business, helping to create a quality work environment for workers, a prerequisite for increasing performance, improving work quality, reducing health problems and stress factors.

Can smartphones pose a threat to their users? And how about security camera system? Is it safer to trust hardware from bigger companies? These are the topics of this article.

In the case of building management, innovation is mainly used to improve the quality of the indoor environment and the comfort of people in the bulding. The role of the energy management of buildings is getting to a whole new position, where each measure is considered not only by looking at money and financial savings, but also by performance and above all health of people.
