Projecting weak current II. – legislation, technical standards and the view of the Trade Licensing Act

12.2.2018 | Ing. Tomáš Mikula
What is the status of technical standards in the legal framework? How about the binding nature of technical standards? Are standards required, are they obligatory? If so, on what terms? If not, then what are they good for? And how is designing of the low-current affected by the Trade Licensing Act?

Human factor in using the CAFM system and the effectiveness of Facility management

5.2.2018 | Jan Talášek, ATALIAN CZ s.r.o. Správa budov ve správných rukou Společnost ...
If we think about the last twenty years, we realize how fundamentally changed the character of production and the nature of services and related nature of the work of many of us. Has the change affected only the tools that we use for everyday activities or the human factor operating new systems has changed the services as well?

Standards versus habits in the field of technical safety

5.2.2018 | Michal Randa, redakce
Most of the companies that benefit from their history of so-called "commercial security" base their business on the knowledge of legislation and they are aware of the importance of ČSN for their business. But closer attention should be given by those who see security as mere business.

Measurement of surfaces in buildings and its consequences

22.1.2018 | Ing. Jan Česelský, Ph.D., VŠB – TU Ostrava, Fakulta stavební
Determining the size of floor areas is very problematic and up to date. The main reason is the inconsistency and fragmentation of the methodology of measurement and surface calculations. The consequences of inconsistency are then known between object designers, investors, administrators, and last but not least among user objects.

The Burning Processes and Their Classification

8.1.2018 | Ing. Coneva Iveta, PhD., Katedra požiarneho inžinierstva Fakulty bezpečnostného inžinierstva Žilinskej univerzity v Žiline
The paper deals with the issue and classification of burning processes. Basic crisis situations and situations that occur during the existence of mankind are also fires. Examination of burning processes is closely related to fires, as they pose uncontrollable and unlimited burning in space and time. Fire occurring not only in the natural environment (eg forest fires) but also in various industrial, transport, manufacturing, processing and storage technologies, in accommodation facilities and elsewhere. Controllable and controlled burning processes can be useful for humans, for example: domestic heating, cooking and others. Uncontrollable combustion processes (fires) can cause serious losses and threats to health, life, property, tangible and intangible property and the environment. Burning is a set of complex physicochemical processes in which flammable substances and materials react with oxidizing agents and change to combustion products (combustion products). Burning is accompanied by intense radiation of heat, light energy, and smoke. The combustion processes can be classified according to different criteria.

Projecting weak current I. – project vs. project documentation

8.1.2018 | Ing. Tomáš Mikula
In the media, the issue of ICT convergence with other fields is mainly described only from a technological point of view. The practical impact on designing and designing buildings is however no longer mentioned. How do you perceive the words project and project documentation you?

Triangular explosion diagrams of flammable substances and their practical applicability

1.1.2018 | Ing. Otto Dvořák, Ph.D., ČVUT Praha, pracoviště UCEEB
The paper briefly specifies for flammable gases and vapors of flammable liquids: the creation and marking of flammability triangles, the possible procedure for shutting down the appliances with flammable substances out of service and, on the other hand, putting them into process in accordance with the relevant flammable triangles, the methods of estimation of the so-called Out- of -Service Fuel Concentration (OSFC) and so-called In-Service-Oxygen Concentrations (ISOC).

Education as one of the prerequisites for improving the quality of facility management

18.12.2017 | doc. Ing. Viera Somorová, PhD., Katedra technológie stavieb Stavebná fakulta STU BA
At present, organizational management's focus is on maximizing the effectiveness of core business in order to increase market competitiveness. This goal can also be achieved by optimizing operating costs by applying facility management to an organization.

BIOFILIA – Design, Bringing Life (Bios) and Love (Philia) to Nature

27.11.2017 | Ing. Katarína Janková, NATURAL SOLUTIONS, s.r.o.
Nature represents for people their natural environment from which they evolved and which they had to adapt to survive. People lived in synergy with nature and perceived it with all the senses from time to time. However, with the progressive development of mankind, this relationship has been ostracized - either as a result of massive urbanization, industrialization, or technological change. This has resulted to such an extent that today we spend over 90% of our time in an artificially created environment. Biophilic design as a tool to reconnect people with nature plays an irreplaceable role in view of the significant positive benefits of this link.

Unrenewable primary energy

30.10.2017 | Ing. Jiří Novotný, Ústav techniky prostředí, Fakulta strojní, ČVUT v Praze, doc. Ing. Tomáš Matuška, Ph.D., Univerzitní centrum energeticky efektivních budov, ČVUT v Praze
Assessing energy performance of the building is also done from the point of view of the need for non-renewable primary energy. A common layman probably does not know what this means. At the same time, the need for non-renewable primary energy fundamentally influences the design of energy sources for heating, cooling, hot water preparation, etc. for a particular building. The need for non-renewable primary energy is one of the three main energy performance indicators of a building, and if it is assessed as too large, the building can not be validated.

Motto of the Facility Management Week 2017 is "Services and people" with subtitle "Services 4.0"

23.10.2017 | IFMA CZ
If we look at man by the view of the economist, we find that people (employees) form a special part of capital. This is an important and very expensive part of the capital, unnecessarily high taxed by us, but also decisive for the success or failure of the business.

Experimental measurement of toxic substances in indoor air before and after renovation of residential building and its heating

9.10.2017 | Ing. Imrich Sánka, Stavebná fakulta STU Bratislava, Katedra Technických zariadení budov
This study investigates the impact of energy renovation on the indoor air quality of apartment building during heating season. The study was performed in one residential building before and after its renovation. Energy audit was performed and energy certificate was calculated for the renovated and the non renovated condition of the dwelling. Objective measurements of CO2 concentration have been used for the evaluation. The average concentrations was much higher after the refurbishment. The air exchange rate was calculated, which was higher in the unrenovated apartments. This study shows that energy renovation of the residential buildings in Slovakia may reduce the quality of the indoor environment in the apartments especially in winter season.
Maintaining a healthy indoor environment requires much more intense air exchange after the reconstruction of the house as it is achieved. Although this is related to energy consumption, it is otherwise endangered by the health of the user. Reducing the thermal energy consumption of the house to the detriment of the quality of the indoor environment and the health of the users of the dwellings can not therefore be considered as a saving and can not be calculated when assessing the energy savings of the building's heating system after reconstruction.
