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.

The upcoming CEN Technical Specification (TS) on assessment of existing structures is related to the fundamental concepts and requirements of the current generation of EN Eurocodes. The final draft of the Technical specification was already submitted to the technical committee CEN TC250 in April 2018. The document concerns all types of buildings, bridges and construction works, including geotechnical structures, exposed to all kinds of actions. It contains requirements, general framework of assessment, data updating, structural analysis, different verification methods (partial factors, probabilistic methods, risk assessment), interventions, heritage building. The submitted contribution provides background information on the principles accepted in the final draft of TS and practical examples of applications of existing structures including panel buildings.

Paper deals with the definition of energy flexible building, its impact on the stability of the grid with the planned increasing share of energy from renewable sources and the possibility of using the heat storage capacity of building structures. Paper further analyzes the selected methodology for evaluation of the energy flexibible building and gives an example of thermally activated building structures.

The subject of the paper is the process of introducing BIM into existing buildings. The BIM model is created either during the preparation of a new investment order or it can be implemented in the phase of operation and use. The aim of the paper is to approach this complex and demanding process and to define the important factors influencing its successful implementation.

In the introductory part of the article are described mechanisms of landfill gas formation and the analysis of its characteristic properties. The following is an analysis of possible gas accumulation and the balance of the possibility of a dangerous explosive atmosphere occurance.

The article focuses on the implementation of the International Standard ISO 50001 – Energy Management Systems. Practical examples illustrate the tools and procedures to meet the prerequisite of the above-mentioned norm, namely reducing energy intensity and greenhouse gas emissions.

By applying preventive measures and using risk management, we can achieve a secure system and eliminate costly solutions. The order of danger of infection sources is very difficult to determine unambiguously.

In July 2018, a two-year monitoring of the FENIX Group a.s. in Jeseník. During this time, different battery operating modes were applied to test their capabilities to ensure the power operation of the object. This article describes the entire period in terms of energy flows in the building. The key parameters are energy consumption, supply to the grid, self-sufficiency of the building from the photovoltaic source and its local use. A number of articles have been written about the building, detailing the building and energy aspects [1, 2]. Therefore, the description of the energy economy in the building will be given only to the extent necessary for a general view of the building's energy.

Since 2007, the European Standard ČSN EN 15221 has been applied. Its first two parts have grown to the current 7 parts. In the spring of this year, ISO 41001 “Facility management” was officially issued, which culminated in the first phase of completing the ISO 41000 global standard.
