The article describes floor surfaces and form of their determination in construction and other fields, such as services, real estate, valuation, facility management and more. In Europe, each country has a different technical standard. This means that when we are determining the type of floor area for buildings with these technical standards, we can conclude that they differ by up to 30 %. Therefore, we chose a sample idea of building on which we symbolized each floor type. We tried to make clear, which constructions and types of floor are creditable and which are not. To demonstrate the importance of correct identification of floor surface we give an example calculation of cleaning services where savings could be seen in the correct determination of the floor surface.

The effort is most builders to get the cheapest project documentation and stamp for start of construction. Little attention has been paid to its proper location. Construction practice is to sit as close to the fence with a neighbor to remain more space for the garden. It should be noted that, under the refers to the construction of any building works that arise construction or assembly technology, regardless of their technical construction design, used in building products, materials and construction, the purpose and duration of use. Under construction is also considered to be a product performing the function of the building. It does not matter if the building is connected to the ground as often by professionals and lay people hear.

Part I of the article is a general discussion of the current laws covering the institution called “smlouva o dílo” (the “contract for a work”). It discusses the issue of defining the work, which has changed relative to the old Civil Code in that the work no longer needs a material expression. It also discusses the options for setting a price for the work, as well as the concluding of such a contract without setting a price. There is a detailed section on budget-based price determination, which is especially useful in the construction industry.

Since the oil crisis of the seventies, the interest given to buildings physics, indoor climate and energy use has strongly increased. Outside air quality in the cities in developed countries has improved significantly in recent decades. During the same period, also the quality of indoor environment has reduced. It is the impact of energy savings, reduced ventilation and the introduction of many new materials and sources of indoor pollution.

The indoor environment of buildings is that part of the environment in which the person is immediately acted on by the construction of the building, its technical equipments, including environmental equipments and a whole set of factors of internal environment. Comfortable indoor environment is essential to productivity, happiness and satisfaction of building users. European standards provide guidelines for what should be comfortable in terms of indoor climate. However, there is often a contradiction between the theory mentioned in these instructions, and real comfort for the user of the building.

Standards and guidelines for estimating the required minimum ventilation rates that we have today are not completed. The objective is to be able to calculate a straight the required ventilation rate, such as calculations for cooling and calculations for heat loads.

This paper is devoted to the assessment of the indoor environment of the building based on the individual components of the microclimate.

The directive 2002/91/EC (EPBD, 2003) of the European Parliament and of the Council on the Energy Performance of Buildings (“Directive on the Energy Performance of Buildings Directive”, EPBD) was adopted after a lively discussion at all levels and with the full support of all Member States and the European Parliament on 16th December 2002 with the entry into force on 4th January 2003. The EPBD is considered a very important component of the legislative activities of the European Union aimed at energy efficiency, which is designed to meet the Kyoto Protocol and satisfies the requirements arising from the Green Papers on security of energy supply.

A recent European Commission Concerted Action focuses on energy performance (“Delivering potential”, October 2006) provides for energy efficiency in the building sector as a top priority. It foresees a key role in the implementation of the EPBD savings potential in the building sector, which is estimated at 28 %, and which may reduce the overall energy consumption in the European Union by about 11 % [2].

This paper is devoted to the various parts of the energy evaluation of buildings according to current European standards.

This year’s ISH fair (Installation, Sanitär, Heizung), held on March 10 to 14, 2015 in Frankfurt, Germany, had a slogan “Comfort meets technology”. It means that the companies aim to supply not only technologically advanced products, but also products with comfortable and easy operation. For systems and components for HVAC controls it means primarily easy-to-understand user interfaces with clean design. It showed primarily at room units, thermostats, and lights and blinds controllers with touchscreens and housings of simple shapes. Regarding system integrators, the point was in making configuration tools easy, and bringing part of the decision-making process to the engineering tools, thus cut down the engineering and commissioning time. Many booths claimed energy savings and energy management, which mostly meant classical SCADA systems and metering data acquisition, as energy management is expert activity, for which the SCADA and communication systems just provide the input data.

Domat Control System backed the hands-on experience this time. Visitors could try engineering and configuration tools at two test desks with both popular controllers (FC010, UC100, IPLC) and news like mark100 to markMX process stations range, programmable in Merbon IDE, the new engineering tool, which supports function blocks (FB) and structured text (ST) as well as compiling of customized function blocks. “Customers like especially support of standard communication protocols, like Modbus, OPC, and BACnet, together with more than 50 system drivers for third party systems, all of this well priced. The Domat components are used not only at homogenous building control systems, but also as a way how to integrate other technologies into third party SCADAs and management systems,” says Michal Šeda, head of product sales department. “With the most active distributors, Vedotech and S+S Regeltechnik, we discussed the market situation and acquired inspiration for further development.” Visitors were also attracted by a new room unit with hi-res colour touchscreen.

Domat Control System s.r.o. is Czech manufacturer of HVAC and energy control systems. The company was established in 2004, starting activities in energy management and control in 2008 by supplies of photovoltaic monitoring systems. About 55 % of the volume in 2013 was export.

The essential data needed for the calculation of the Certificate of energy performance (PENB) are the data arising from the documentation of the construction. Providing that there is no documentation available, it is necessary to draw it up. The specialist makes a simplified electronic documentation containing all the necessary information to calculate the PENB. The gathered data from the drawing is stored in the database of the CAFM system ARCHIBUS. The data from the 3D BIM model can be placed into the same charts, therefore this database can gather this data independently of whether it was created based on electronic documentation in 2D or 3D models. The creation of the certificate is automatic.
