Creating of indoor environment in the work area in industrial buildings should be based on cooperation between heating and ventilation. However, practice shows that this is not truth in many cases. Both professions are many times designed separately. Result is their noncooperation leading to a mutual obstruction in terms of disposal location or functional operation of the systems. Creating a heating and ventilation system, which would both be designed in accordance with applicable legislation and it would create an optimal indoor environment for people in working area, to find solution in combination of radiant heating with ventilation air recovery unit.

Increasing building energy performance has become an obligatory objective in many countries. Thermal bridge is a major cause of poor energy performance, durability, and indoor air quality of buildings. This paper starts with a review of thermal bridges and their negative impacts on building energy efficiency. Based on published literatures, various types of building thermal bridges are discussed in this paper, including the most effective solutions to diminish their impacts. In addition, various numerical and experimental studies on the balcony thermal bridge are explored. Results show that among all types of thermal bridges, the exposed balcony slab produces the most challenging thermal bridging problem where an integrated thermal and structural design is required. Using low thermal conductivity materials in building construction could help in reducing the impact of thermal bridges. Finally, further investigations are needed to develop more innovative and effective solutions for the balcony thermal bridge.

Abstract

The yurt is one of the ancient living units for the nomadic cultural country. The yurt is a nomadic vernacular architecture, which has been developed for 3000 years. There are 31 counties using the yurt, out of which 13 of them use their traditional yurt around the world. Basically, the yurt was used as residential housings and today, also to some extent, for commercial and touristic purposes under different climates. Analyzing existing literature, as well as scientific publications it is apparent that besides architectural and structural topics, there is no existing investigation or published paper about building physics analysis of these buildings. Current research aims to create a database about energy and climate comfort qualities of traditional yurts using dynamic calculation tools. As a result, to intend to learn from the traditional yurt technology and to develop a completely new and modern building prototype based on the yurt-experiments in next step of research. Firstly, finding optimal solutions for a contemporary yurt-building' should be applied under Mongolian climate conditions, since this form of housing is still used in this country, and, in addition, the comfort and energy performance of the yurts were surprisingly satisfactory under extreme weather conditions, by temperature differences between summer and winter of approx. 80 K.

All building materials can be affected by microbiological agents during their lifecycle. The presence of microorganisms changes the appearance of the surface, degrading it, and they can even cause health problems to the residents. The biological susceptibility is dependent on the content of nutrient based on organic compounds. Thus one of the most susceptible of those materials are earthen construction materials. The degree of fungal growth is influenced by the chemical composition and plant fibres additives as well as the external conditions such as temperature and relative humidity.

The earth plastering mortar has started to gain more attention recently as it is considered to have a low environmental impact and to increase the indoor air quality. Mechanical and physical characteristics of earth materials were studied by a number of authors but the knowledge about the biological resistance of the material is scarce.

This study intends to look into the issue of the biological colonisation of earth plasters depending on the relative humidity. The samples, made of four types of earth plasters with different plant fibres, were placed to an environment of the relative humidity ranging from 33% to 100%. During a period of 4 weeks the extent of fungal growth was observed.
