National Renewable Energy Action Plans (NREAP) of each EU countries in graphical and tabelar forms. Part three - final energy consumption for heating and cooling and share of RES on the consumption for heting and cooling.

Article originated from the result of a graduation thesis that had been engaged in the design of air conditioning in a sports hall. An emphasis was insisted on ensuring the optimal microclimatic conditions in the ice stadium in the framework of the solution. In particular, it related of places affected by the ice surface with respect to the generation of mist and condensation of humidity at construction structures as well as ensuring a necessary comfort for spectators in the area of stands and terraces.

Lots of energy saving projects of public swimming pools were realised during last few years in Germany and Austria. Some of them were realised by the EPC method (Energy Performance Contracting). This paper shows two of them.

Low energy (LEB) and passive buildings (PB) are becoming standard for new constructions in EU countries. They aren't experiments anymore, but absolutely ordinary mass production of sophisticated residential buildings. Only in Germany, Austria and Switzerland there are already thousands of buildings that meet the passive standard and their number doubles every year. The cost of passive buildings is only 5-7 % higher than those of conventional ones, and yet, their consumption of energy and heating is up to 90 % lower! Part 4 about circulation system air heating system with a controlled proportion of ventilation air and heat recovery, and some design principles for design and ventilation NED EPD.

Part 3 about ventilation systems for normal buildinghs and EPD.

The current market is over saturated with different technologies and products that promise to rocket return, versatile use and effect for everyone. As it is the truth is a complicated thing and this article does not even look for it. Each technology certainly has its place, but if the specifications is thoroughly examined. The aim is (on a simple example) to compare seemingly incomparable. Custom effect of insulation of the facade versus applications of controlled ventilation with heat recuperation in classic family house.

The cost of passive buildings is only 5-7 % higher than those of conventional ones, and yet, their consumption of energy and heating is up to 90 % lower! Part 2. about regulation ventilation system.

Requirements for high energy efficiency and energy savings in heating are most often realised by thermoinsulating of facades and changing of windows. It is seldom known among nonprofessionals that this type of energy saving can cause very negative consequences for human health.

Paper provides measurement results of hygrothermal microclimate several bathroom in the prefabricated house for a period of 1.5 months.

The Author engages in his article in the technical and normative conditions with respect to fire-stopping insulations for ducts, which unfortunately are not enough known and experienced in practice. He synoptically and understandably introduces the principles and rules of the said problems and describes important design details, as well. Certain critical places fire-stopping insulation systems and their assemblies are correctly emphasized.

Natural ventilation is the usual mode of ventilation of residential buildings. There is no fan. People think, this system has no energy requirements, but continuous air flow causes heat loss by ventilation. This energy consumption is higher then energy for controlled forced ventilation.

Author raises discussion and proposed changes in the rules of the energy audit. Draws attention to the criteria for evaluating alternatives and to small requirements for variability solutions. Read controversy of the author and reviewer who considers the methodology as sufficient and sees a problem in processing audits.

The group of twelve residential passive houses and school facilities in Koberovy can be characterised as the first mass project of experimental construction based on energy efficient wooden structures carried out in the Czech Republic. The construction is located on a plot of land oriented to the South. The concept respects the regulations for the protected area Czech Paradise within urban communities, which require saddle roof, entrance through the longer part of the façade, limited glazing areas, among others. The concept does not result in a monotonous terraced construction. The new housing estate is logically related to the current character of the surrounding buildings in the village.

Boiler room with gaseous fuels are undoubtedly the work, which is necessary primarily for the protection of the public interest (safety, protection of life and health of people, etc.) to pay attention to the stage design and installation. Extension, then ensure their safe and reliable operation.

Additional glazing of a loggia in a prefabricated house can significantly affect the energy performance and internal air quality of individual flats. The effects of glazing are not entirely explicit and they depend on the specific solution of the construction, original thermal characteristics of the building as well as on the way the building is used and on the behaviour of its users. The mentioned study analyses several cases of glazed loggias using detailed simulation method (software IES ) and it attempts to express possible energy savings and some of the influences on the internal air quality of adjacent residential spaces.

In this article, the author deals with the vent rotating heads, which are widely available as replacements for roof fans in the ventilation systems of sanitary units. Measurements that have been carried out will show what may be the realistic expectations of users who install these ventilation systems.
