Information Models

The article analyses the field of civil engineering from the point of view of the necessity of implementing various BIM modelling tools in the management of energyefficient buildings. Information on BIM modelling tools that may be needed in the maintenance of energy-efficient buildings has been collected. Five main tools have been identified and described, including BEM and CFD technologies, which have been reviewed in more detail. The requirements for information models that integrate with third-party BIM modelling tools for analysing building thermal performance and indoor climate have also been identified. The article provides examples of foreign experience in the use of BIM modeling tools used in the analysis of existing energy-efficient buildings.

The society lays stress on today's buildings, particularly in terms of energy-efficient buildings and ecology of buildings. Accordingly, not only from a technical technical point of view, it is important to give sufficient attention to the foundations of building. The popular way of foundation of lightweight buildings is due to the growing interest in timber houses the foundation above a ventilated air gap so called Crawl Space. The article deals with the temperature and humidity field which is located in the air gap under the construction of wooden building in the climatic conditions of the Czech Republic.

An experimental study was planned and executed for the application of Phase Change Materials (PCM) containing fiber-reinforced cementitious panels on buildings. The objective of the research was to enhance the thermal performance of the panels. Panels with the dimensions of 60x120x2.5 cm were produced and experimental investigations about the thermal and the mechanical performance of the composites were carried out. PCM containing composites showed higher latent heat capacity and lower thermal conductivity. Reinforcement with chopped fibers compensated the strength loss due to PCM in cementitious panels. Specific fracture energy of the panels increased with increase of PCM ratio. PCM containing fiber reinforced cementitious panels showed great potential for energy efficient buildings with enhanced thermal and mechanical properties.

The Impact

Energy supply, the increasing demands for energy, climate change, and the imperative to reduce greenhouse gas emissions must be considered in designing buildings. In order to design energy-efficient buildings, there should be accurate information about the thermal performance of the building. The thermal simulation readings should be precise. Its precision will also have a definite indication of the operational energy costs enabling the likelihood of conserving more energy used in building operations and reducing the greenhouse effect that is a result of emissions of greenhouse gases. Energy-efficient buildings are vital as they reduce the consumption of energy in and allow sustainable development. Erecting such buildings will require correct and realistic prediction of the buildings performance when subjected to a wide variety of harsh weather conditions in order to have a view of the impact of all the physical elements that influence the thermal performance. The behavior of the occupants also influences the thermal performance of a building. To achieve this, energy assessment instruments are used to accurately forecast the buildings thermal performance. This paper critically reviews energy rating methods for housing and the limitations of assessment systems.

And Training

Concept of sustainable buildings is defined as use of various strategy and standards of working to intensify the quality of life of occupants, secure the environment of neighborhood by lessen the construction rate of consumption of natural resources. Conventional buildings are not much conveniently rated over energy efficient buildings as per indoor climate basis, whereas when studied furthered the users have different reviews. The quality occupancy when evaluated from varying results of users has various aspects. Inappropriate use of building may concerns in bad experience in conventional buildings by the users. New area for further research could be identified as required information for an operation and use is difficult for overall quality experience of the building. There is a shortage of research that takes into account of “Unawareness” or “inconveniences” of occupancy behavior with a survey defining the authentic gap in research. Research on use of energy efficient buildings is increasing, but there is still a scope to give more information and training in operation and use. This paper justifies occupancy evaluation with indoor climate, building operation, occupancy attitudes, and economic.

The development of new building materials is a crucial engine for promoting the development of green energy efficient buildings. In this paper, based on the excellent properties of light guiding of resin materials, a new type of resin translucent mortar-based concrete (RTMC) was researched; meanwhile, transmittance properties, mechanical properties, and thermal performance were studied, respectively. The results showed that the resin material possessed excellent light transmittance within the thickness of 100 mm, which can be as high as 93%. Moreover, when the area ratio was within 5%, the compressive strength of RTMC was close to that of plain concrete. Besides, RTMC had excellent thermal performance that the thermal conductivity of RTCM was 0.3815 w/(m·K), which was 60% lower than 0.89 w/(m·K) of plain concrete.
