Abstract: The article discusses basic regulations and demands for windows and natural lighting. It presents results of analysis of lighting of the chosen interior space taking into consideration periods of exploitation of the artificial and natural illumination. The employment of glass of different light permeability were taken into consideration. Results of calculations were used for evaluating time of electric energy needed for artificial lighting in analyzed variants of natural light systems.

Abstract: The paper presents the results of the research in building after thermal modernization. The analysis includes energy consumption for heating of the building, the nature of the microclimate in rooms and pollutant emissions to atmosphere of fuel combustion products. This analysis was carried out to evaluate the influence of energy saving activities on microclimate interior conditions and the state of the external environment.

Abstract: The article deals with energy rehabilitation of a building with damaged waterproofing of its lower structure. The reference construction is made of fired bricks, whose functional properties are perfectly fine, but the thermal insulation properties are insufficient for this time. The most common solution of such a problem is the application of a thermal insulating material based on expanded polystyrene on the building envelope. Unfortunately, these solutions often entail the risk of moisture problems in places that appeared to be dry before. The article compares the current solution with the new one relying on material based on calcium silicate [4] with high moisture transport capabilities as an alternative insulation of these buildings.

Abstract: Energy labelling of windows has been introduced in some Member States - for example Denmark, Finland, Slovakia and the UK. The UK BFRC scheme on window energy labelling has proved very efficient in communicating to the general public about the energy saving properties of high performance products thus contributing to their faster uptake. Slovak labelling system was introduced in 2008. The paper deals with main principles of energy rating system used in Slovenergookno. National system for rating the energy efficiency of windows and is recognised within the Building Regulations as a method to show compliance for your replacement windows installation..

Abstract: In the period on 1982-2012 in the capital of Armenia there were done a lot of construction works. Because of civil construction activities geological layers of the ground are destroyed and the risk of seismic stability is increased. There were destroyed or concreted the ancient water tunnels which create unpredictable results for hydro geological activities of the city. Flood risks are increased because of there were blocked the entrances of artificial water chambers. In the result of concreting Getar River flowing through the center of the city there is decreased vertical air flood circulation in the city which causes air pollution increase in the city. Further satisfaction of public interests and implementation of state policy will cause future ecological disaster for the city.

Abstract: Here in the article is shown monitoring mode of ambient air in urban systems parameters, green masses on the negative impact of adverse effects of changes in the method of assessment for GIS monitoring of results based on the analysis , Landsat 5,7,8 satellite TM, ETM + sensors through the OLI the method is based on spectral sensing different physical domains through a combination of urban ecosystem , mainly heat and pollution in urban vegetation ( gardens , parks, walking areas , etc. ) change the volume and quality assessment. Here are presented monitoring and management theory ( virtual ) scheme critical analysis.

Abstract: In the last twenty years, the rapidly changing laws in the field of thermal engineering and energy and the resulting demands on buildings. As a side effect of this development is reflected microbial growth on the outer composite panel cladding, which contributes to the degradation of certain facades and increase the costs of remediation such impairment envelope. Papers aims do define the general context and the factors that affect microbial growth on external systems, composite cladding panel buildings, especially prefabricated buildings completed in the second of the last century.

Abstract: In the last decade we have been faced with a problem with biotic infestation on frontages in engineering practice. This phenomenon has been detected especially on a panel building on which additional contact thermal insulation is applied. The contribution is concentrated on the particular panel building of the series T0 6B-BTS from which samples of the external plaster were taken.

Abstract: Environment is becoming a significant development potential of a country and the effort dwells in minimizing the negative impacts affecting its quality. Researches show that in the branches of industry in the EU construction is the third largest polluter of the environment. Requirements of securing the environmental protection are more demanding when it comes to qualitative properties of construction materials, building machines, technological building processes, etc. Due to this it is necessary to derive from the confrontation of the current status with requirements of securing maximum effectiveness of the building production process at minimizing negative impacts on the environment.

Abstract: Abstract: The studies on operating effectiveness of sand traps in partially acting facilities of the Yerevan Aeration Plant have shown that along the satisfactory clarification of silts (sand) of mineral origin at the facility bed materials of organic origin are also trapped causing sand traps failure their main function which is clearly separation of the two types of waste waters. In addition serious problems and difficulties arise also in the sand removal. Therefore, in this paper it is suggested both technological ( grounded reduction of the number of sand traps and including in the mechanical unit clarification plants equipped with bioflocculation chambers) and constructive (by substantially decreasing the length of sand traps) solutions. It also is suggested for the first time to apply a new technology designed to remove the sand from sand traps both in the above aeration plant and new industrial and domestic waste water clarification plants under engineering design.
