The importance of maintenance of buildings in the operation of real estate principles Facility management is huge. Properly and efficiently carried out maintenance of buildings helps to smooth and especially trouble-free operation, respectively use of the buildings. The effort of each owner, respectively operator is to make the operation, respectively. Use benefited maximum benefits. The aim of this article is to define a species, processes and other forms of maintenance that his efforts will help streamline.

The design and installation of building automation systems constitutes one of the essential parts of the system input peripherals - Sensor environmental variables. Market with sensors of environmental parameters in buildings, in comparison with the sensors industry some specific characteristics.

This article aims to introduce Facility management as defined by standard EN 15221, to describe the development of this field, to determine its target, to identify ways in which the Facility management is implemented, to define the level of management where processes are managed and finally clarify the position and mission of the Facility manager, whether the service recipient or the provider. This article summarizes the basic facts and information about the dynamically developing field, which over time becomes an integral part of our working life.

The question of reliability and at the same time quality of security systems is the most important criterion for selecting a particular type of security. The most dangerous from this point of view are perimeter systems that virtually in all modifications and technologies are greatly subject to the influence of external conditions and distractions. Due to this fact many false alarms quite often prevents their actual use (at least in civilian areas). This is why we (in the Laboratory of security systems Faculty of Engineering CZU) were searching for a way how to increase the efficiency of employment of the discussed perimeter systems. We wanted to enable problem-free utilization in the commercial area at a moderate price if possible. The solving of the problem by way of minimizing false alarms failed when changed to a different physical principle of detectors. Therefore we chose a different approach – we made a perimeter system with movable and automatic alarm verification.

Change of the standard ČSN 73 0810/Z1 (valid from  1^st June 2012) introduces a new term - so-called „equivalent DP1“.This represented an exception in the classification of non-combustible components for some products. This exception was cancelled by the Change ČSN 73 0810/Z3 valid from 1^st July 2013.

Of course, the social order is low-energy buildings to be also effective. However, this objective cannot be only declarative nature, but must be supported by correct results showing that the investment plan will generate real economic effect in the form of profit or positive cash flow for an investor or user for the period considered.

Centralized provision of hot water in the apartment building is associated with the specifics of four (commercial space, unmetered amount of heat for the preparation and distribution of hot water, the limits of specific consumption of heat, heat supply technology for domestic hot water through residential transfer stations).

Nearly 100 of definitions that explain the basic concepts that appear in facility management. Dictionary can help you at the first orientation in facility management or the need for precise terminology.

In relation with the implementation of the revised EU Directive 2010/31/EU on the energy performance of buildings are currently changing some of Czech legal regulations and new methodology for energy performance assessment is introduced . This article focuses on an example rating the standard family house with conventional solution of building envelope and technical systems, using the new evaluation method. For this object will be also an obligation to issue an energy performance certificate as required by the Consolidated Act No. 406/2000 Coll., as amended.

The author determines this article to parties interested in business in the field of the technical infrastructure building management. He provides the fundamental information as concerns the provision of technical services at the real estate management in the area of the building technical facility in all buildings of the client of the services provider in the formof the facility management. The author deals above all with buildings serving exclusively for the administrative purposes within the range from large buildings in the possession to small workplaces in leased buildings.

Article discusses the possibility of using gray water in buildings and as the example cites the hotel Mosaic House in Prague. This hotel is the first building in the Czech Republic, where they were used gray water for flushing toilets and for cleaning. The article also described the gray water treatment technology.

One of the reasons why building with almost zero energy consumption does not meet the expectation is that it may be too complicated. Another factor is that the project may be too optimistic, and other unforeseen factors, such as office equipment, which actually dominates the energy balance of the building.

There's no law regulation to fix details of gas and electricity supply billing for big customers, such as industrial customers etc. Customer must fix it with the supplier on his own initiative in the supply contract.

The European Union is committed to reducing energy consumption in the built environment. Since the heating, ventilation and air conditioning (HVAC) represents approximately 11% of the total electricity consumption in Europe, these systems are an important part of the commitment of the EU. In this article, we discuss two specific aspects of HVAC energy efficiency, both are based on that understanding how the commercial buildings work in real life is the first step towards reducing energy consumption.

In connection with the implementation of the revised European Directive 2010/31/EU on the energy performance of buildings, certain legislative provisions such as Decree No. 148/2007, Coll. Replaced by Decree No. 78/2013, Coll. are currently amending. This article is focused on the changes associated with the energy certification of buildings, the "ENB", from the perspective of changes in the evaluation ENB.

Today's world is connected with use of computer technology. Of course, there is an increase of security threats that are related to computer and computer networks. It is not just about IT security systems, but in terms of security objects and their parts into which access is restricted whether it be for any reason. Therefore, the user identification is one of the most important parts of the security access systems. To work on the development of functional, reliable and yet not too financially demanding system, is needed to be familiar with existing systems.

The new standard CSN 75 5409 is valid from March 1^st 2013. Technical Report on protection against Legionella will apply from May 1^st 2013. In case of conflict of energy saving and hygiene prevails hygiene. Size of the hot water tank is chosen according to the requirement of heat pump. Volume of accumulation of solar systems is about 50 l / m ² of collector area.

The paper focuses on the conditions of fire and risk connected with dust layer. The next part is about thermal degradation of biomass and heat transfer on dust layer. The next part shows test methods for flame spread. The connection of dust layer and possible secondary explosion. In the article is highlighted connection with space and equipment cleaning due to ČSN EN 60079-10-2.

Benchmarking is a continuous and systematic comparison of own performance in productivity, quality, and manufacturing process, with enterprises and organizations representing excellence. "Benchmarking is the process of identifying best practices in other organizations and learning from them."

Each interior where people live, must be - to ensure a wholesome environment - ventilable and adequately ventilated. Our regulations, although they do not always speak the same way, provide sufficient evidence for the solution. But sometimes reality is quite different.
