The article deals with energy supply of low-energy and passive solar houses. It presents the integral conception of the further development in Germany and evaluates the pieces of knowledge up to now concerning the technical equipment of the low-energy buildings.

The article deals with the influence of outlet opening flow cross section of the enclosure located above panel radiators on radiators heat output. It presents the experimentally determined values of correction coefficients of heat output of radiators under application of the enclosure in the form of e.g. fitted kitchen installed right to the wall on which the radiator is mounted with outlet enclosure situated in the worktop above the radiator.

Explanation of technical rules changes for combustion air supply and ventilation of gas-fired boiler houses. The contribution deals with current rules and requirements for the design of minimum continuous intensity of gas-fired boiler houses ventilation in connection with other regulations under sufficient airing of the whole space of the boiler house and maintaining the acceptable temperature of inside air in the boiler house under minimum energy requirements.

A team of authors evaluates the influence of the supplementary glazing of loggias on the basis of the evaluated operational data of the implemented constructions. The impacts of the supplementary glazing are evaluated from the point of view of the thermal comfort, light comfort and acoustical comfort. At the time of tightening the regulations concerning the reduction of the car traffic noise influence on the climate comfort inside of the surrounding buildings and at the time of the new energy consumption regulations the glazing of loggias is a positive contribution to the provision of the well being in residential buildings.

Sunspaces do not have auxiliary heating themselves and reduce heat losses from the spaces to which they are attached by reducing conductive losses through the wall of the heated building and possibly by providing some ventilation air at a higher temperature then ambient air. Influence on thermal transmittance of the separating wall is expressed using simplified method.

The article advises the authors of the Fire Safety Solution (further as „PBŘ“ only), ie. authorized engineers and university trained engineers in the field of the fire safety of constructions [1] how to proceed with elaboration of the construction PBŘ. It presents the new legislation requirements in this field, and it informs what has to be included into this part of the design documentation and it refers to appropriate legal regulations and technical standards, and it informs about the new interpretation of the fire safety equipment.

The article deals with electric power generation in the Czech Republic and with the influence of this power generation on the production of substances contaminating the atmosphere. There are indicated numerical values valid for 2000 that are nowadays applicable for environmental evaluation of economies proposed within the bounds of energy audit.
