The article considers the standard EN 442-2, which assumes a linear course of the temperature exponent with height for a given type of radiators. It focuses mainly on panel radiators, although it does not omit other kinds of radiators. It points to the fact that the dependence of the temperature exponent on height is not linear and increasing for a given type, as assumed by the characteristic equation of the type. Results are based on the evaluation of the data collected from the radiator manufacturers.

The heat pump with earth wells is a source of heat and cold for a university building in the center of Prague. Analyzes of measured data from the operation of this system are performed and the issue of parallel production of heat and cold in the context of sustainable development and buildings with minimal energy consumption is discussed.

The common view that heat pumps are only suitable for new or refurbished buildings with a focus on energy can be considered obsolete. This is evidenced by the results of research at the Fraunhofer Institute (ISE) found in older buildings in several long-term projects.

High quality of the indoor environment expressed by indicators such as air temperature, relative humidity, concentration of carbon dioxide, or lighting has great impact on human health, comfort and performance. Therefore, the contribution focuses on the effect of an increase in indoor temperature on energy consumption.

The author describes a systematic procedure leading to the processing of the audit and provides an overview of the necessary documents. The elaboration of the audit and the implementation of the proposed measures is a basic prerequisite for savings. Without subsequent evaluation of results and adjustments of operating modes, etc. however, the expected savings effect may not occur.

The low heat loss in family houses enables comfortable hot air heating with air-to-air heat pumps. The authors give an example of the conditions for obtaining a subsidy from the „Nová Zelená úsporám“ (Green to Savings) program. Achieving the highest category of the NZÚ subsidy is also realistic in the „new buildings“ category.

By using an electrostatic precipitator, dust emissions (TZL - solid pollutants) from the solid fuel boiler were reduced well below the level of requirements according to ČSN EN 303-5 - class 5 and the Ecodesign Directive. This work describes the design of the separator and also presents the achieved emission parameters of the boiler with an output of 250 kW.

Room height and the risk of condensation affect radiant cooling performance. Correction factors are determined for freely suspended radiant panels depending on the height and temperature gradient of the air. At a height of 14 m and a gradient of 0.5 K / m, the total cooling capacity is up to 40% higher than the table.

The article deals with the effect of the indoor air temperature attenuation during intermittent heating on the energy consumption and the quality of the indoor environment in an existing office building with electric direct heating system.

This study was focused on the observation of a brick chimney with an isostatic liner, intended for the removal of flue gases from a combustion plant of low heat output burning solid fuels, with regard to the occurrence of condensation.

The cause of the odor after the generational replacement of the gas boiler can be reduced air exchange in the room, improperly designed waste pipes, or even insufficient hygiene. The level of cleaning and hygiene is solved by the apartment user. Sufficient ventilation and treatment of the waste pipe, such as the installation of an aeration valve, should be designed by a person skilled in the art.
