Buildings have U-shape façade designs for certain purposes such as lighting. However, such designs may lead to a higher fire hazard. In this paper, large scale experiments of upward flame spread over XPS insulation material were conducted to investigate the fire hazard of building’s U-shape façade wall geometry. Comparison to previous labora­tory scale experiments were also presented. Theoretical analysis was performed to reveal the mechanism of the U-shape geometry’s influences. It is found that such geometry design would increase the fire hazard of buildings: flame spread rate and flame height increased with U-shape’s geometrical factor. The results agreed with theoretical analysis. It is ex­pected that the buildings’ U-shape façade wall geometry would greatly benefit flame spread for full scale applications and increase the fire hazard. Thus engineers should be careful with such façade wall designs, especially for residential building designs.

The paper presents the study on theoretical heat gain for a residential building located in hot-dry climatic zone of India. The location is city Kota (25.100 N, 75.830 E). To determine heat gain, three different methods have been used. The aim of the paper is to study the heat gains and also to compare the three different methods. First method is CLTD/GLF method which is taken from ASHRAE 1997, second method is CLF/SCL/CLTD method which also taken from ASHRAE 1997 and third method is RLF method which is taken from ASHRAE 2013. After that comparative study has been done of all three methods. For the study a typical middle income group residential house has been considered. The model house is taken of size 12 m x 15 m with three windows of size 1 m x 1m each and one door of size 1 m x1.5 m. The walls are brick wall and roof is taken of RCC. From the analysis it is found that CLTD/GLF method predicts heat gain towards lower side whereas CLTD/SCL/CLF method values are higher and RLF values lies in between being more close to CLTD/SCL/CLF method. An important point to notice on comparison of results is that all methods predict around 50% heat gain through roof for this building structure. Another major contribution to heat gain (around 30%) is through walls. The window to wall ratio for the building is 1.9% and therefore the effect of heat gain through windows is only around 8%. Other factors contribute only a minor percentage to the overall heat gain. Thus, from the results it can be concluded that in order to reduce the heat gain and cooling load, major attention must be paid on roof and wall heat gain along with the other factors. Suitable passive measures can be identified on the basis of heat gain study.

The building sector continues to register a significant rise in energy demand and environmental impact, notably in developing countries. A considerable proportion of this energy is required during the operational phase of buildings for interior heating and cooling, leading to a necessity of building performance improvement. A holistic approach in building design and construction represents a step to moderate construction costs in conjunction with reduced long-term operating costs and a low impact on the environment. The present paper presents an experimental evaluation of the energy efficiency of a building under real climate conditions; the building, which represents a holistically designed modular laboratory, is located in a moderate continental temperate climate, characteristic of the south-eastern part of the Pannonian Depression, with some sub-Mediterranean influences. Considerations for the holistic design of the building, including multi-object optimization and integrated design with a high regard for technology and operational life are described. The paper provides a genuine overview of the energy efficiency response of the building during six months of operational use through a monitored energy management system. The energetic analysis presented in the paper represents an intermediary stage as not all the energetic users were installed nor all the energetic suppliers. However, the results showed a reliable thermal response in the behaviour of recycled-PET thermal wadding used as insulation material in the building and for the intermediary stage in which the building has only secondary energy users, the energetic balance proves its efficiency, keeping the buffer stock of energy high values over 90%.

It is very important to use the daylight in the building design, which is allowed by the windows into the buildings, to reduce the energy consumption. However, on the other hand, the performance of daylight varies according to the floor levels of the building. This research focused on the investigation of the correlation between the performance of daylight and window areas according to floor levels through field measurements and simulation experiments in the residential building. The aim of this research is to derive the adequate window areas according to the floor levels with respect to the orientation of the residential building to achieve the optimum level of daylight and indoor temperature in the livable areas of a residential building. The case selected is residential building from Nagpur region, of Central India. It has a hot and dry climate. The evaluation of daylight level has been done with selected parameters like percentages of Carpet Area to Window Ratio (CAWR) and Orientation by using daylight metrics, namely Useful Daylight Illuminance (UDI) (with Daysim and Radiance analysis tools plug-in Ecotect 2011 software). The findings of this research are the adequate area of window according to floor levels with respect to the orientation in the livable areas of the residential building.

In the article research results are presented, which aim to provide evaluation of thermal protection properties of volume textile materials. However, as a result of experts wearing it has been revealed that by their operational performance their characteristicsare quite high to such materials: Holofiber, Tinsulate, Arctic, etc. At the present time to research thermal protection properties of sewing materials methods are used that can be divided into 2 groups: Methods based on the principle of steady heat mode and Methods based on the principle of unsteady (regular) mode. New device has been developed which allows to simplify both the schematic diagram and the methodological approach to experimental evaluation of thermal protection properties of volume textile materials. The corresponding experimental research were held based on the developed bicalorimeter. Study results allowed to establish heat insulation material «ArcticP» possesses the highest thermal resistance.It is located with its metallized coating facing outside. High values of thermal protection properties of this material are explained by availability of metallized coating from outer side which ensures partial heat reflection.. The research was made in Don State Technical University within the framework of State Assignment of the Ministry of education and science of Russia under the project 11.9194.2017/БЧ.
