The use of insulation materials in modern buildings has made a huge contribution to energy saving. However, due to the poor heat resistance of the insulation material, much heat and toxic fumes will release when burning, a serious threat to the safety of life and property, hence its shortcoming cant be ignored. The calorific value of building materials is the important parameters to characterize the potential fire hazard of building materials and its also the essential basic data to calculate its combustion releases heat and fire load; non-combustibility test can determine whether the material directly contributes to fire. The methods mentioned above were used in this paper to study the typical eight types building insulation materials in China, and further combustion performance analysis and proposal were made to give recommendations for improvement.

Проанализирована роль декоративно-отделочных, облицовочных материалов и покрытий полов в формировании опасных факторов пожара (ОФП). Проведены расчеты распространения ОФП в модельном помещении с учетом вклада облицовочного материала стен и потолка. Показана возможность применения рассмотренного подхода для моделирования условий (стандартных и нестандартных) испытаний строительных материалов и конструкций на пожарную опасность (например, фасадных систем) и гибкого нормирования при использовании декоративно-отделочных, облицовочных материалов и покрытий полов в зданиях и сооружениях.Article presents the study of the possibility to describe thermal decomposition and thermal oxidation processes of fire load finishing materials by means of the kinetic parameters. These parameters are defined by results of termogravimetric analysis for modeling the dynamics of fire development. Nowadays the problem of modeling the distribution of hazardous fire factors (HFF) in buildings and constructions has wide practical application, however techniques of HFF modeling do not take into account as fire load finishing and facing materials of building and construction premises in development of a fire, so they are not considered at an estimation of safe evacuation of people from buildings and constructions as well as at calculation of fire risk, too. When describing a seat of fire there are used fire hazard indicators having essential uncertainty according to the technical literature sources and experimental data while formation should be based on the possibility of their thermodestruction and thermooxidation under the influence of heat loads of various intensity. At the same time, the speed of the specified processes should be interconnected with values of heat loads. The presented work is of current importance because it is necessary to describe thermodestruction and thermooxidation processes of fire load material at modeling the dynamics of HFF distribution in buildings and constructions by means of kinetic parameters received as the results of thermogravimetric analysis. On the example of calcium silicate and wood composition there are carried out calculations of HFF distribution in a test premise taking into account the contribution of wall and ceiling facing material. There is shown the prevailing, in comparison with a seat of fire, contribution of wall and ceiling facing material to HFF formation at its initial stage which is especially important from the point of view of ensuring safe evacuation of people at fire in buildings and constructions. On the basis of the conducted analysis of research results there are developed proposals for applying the considered approach to model conditions for (standard and non-standard) tests of building materials and structures for fire hazard (for example, front systems) and flexible rationing of use of decorative - finishing and facing materials as well as floor coverings in buildings and structures.

Building insulation is considered as a solution to reduce the energy cost for both residential and commercial buildings. However, determining the best combination of insulation materials that result into the lowest total ownership cost is now becoming a bigger challenge. Various factors influence the efficiency of heat transfer within a room including geometry and size of the room, ambient temperature, heat and sink sources presented inside the building, type of insulation materials, etc. The aim of this paper is to develop an optimization-based decision making tool to help house owners select the best combination of given insulation materials considering all these factors. The purpose of design approach adopted in this paper is to minimize total ownership cost while providing the required heating in the building. The SQP, Quasi-Newton, line-search algorithm was used to obtain the optimized thermal conductivity values for the combination of insulation material to be used in the walls, floor, ceiling, window and the door of a room, along with the width of the air gap to be kept. The results help in deciding what combination of insulation material will achieve the required heating for the house owner while keep the total cost incurred to be minimum.

Insulation Materials

Modern technologies are not standing still, and scientists are trying not only to invent new building materials, but also to find non-standard use of various raw materials that were previously considered unsuitable for use. Innovative technologies are actively used for modern construction of buildings, in particular, some types of new materials are used in the construction of various facilities. This is especially true in areas where it is not possible to import or use ordinary building materials for various reasons. Often, when designing a building, developers are wondering whether it is worth making the house warm during construction, and which insulation for the walls of the house is better to choose. This article addresses the question of which insulation for walls is most suitable for construction. The most common are mineral insulation, which are represented on the market today in the form of basalt slabs, fiberglass, etc. They have such advantages as low thermal conductivity, good thermal insulation and vapor permeability. The article presents a table with comparative performance characteristics of a mineral wool stone slab and a fiberglass slab. Stone or basalt wool has several advantages. It is able to withstand significant temperatures and temperature changes, the mats are easy to transport, convenient to install. In our opinion, a serious alternative to basalt in the production of thermal insulation materials is volcanic ash. One of the main features of volcanic ash are its building qualities, such as good thermal insulation and an environmentally friendly composition. Since here we are considering the possibility of producing insulation materials based on volcanic ash, we performed a thermal calculation of the enclosing structures. Also in the tables are the costs of transportation of volcanic ash from the field to the point of the proposed production of insulating material. Volcanic ash can be widely used in countries with high volcanic activity as an inexpensive raw material for the manufacture of building materials. It does not require additional processing and has a number of useful properties.

Research Gap

Installation of insulation materials in buildings can reduce the usage of air conditioners by retarding heat flow into the building. Aerogel is one of the best insulation materials with distinctive properties that can replace existing building insulation materials such as fibre glass and polyurethane. However, brittleness of Aerogel makes it difficult to handle and disqualifies its viability as a building insulation material. Reinforcement of Aerogel with binding materials can improve its mechanical and thermal properties to overcome its brittleness. However, only a few studies have been carried out on this area. Furthermore, from the few existing studies, vital information such as thermal conductivity and specific application of the reinforced Aerogel studied were not considered. As an initiative to fill in this research gap, a review on reinforcement of Aerogel is presented.

Abstract Mycelium composites is a new class of renewable materials which can be used for heat insulation of buildings. Use of the composites would help to reduce both operational energy consumption and embodied energy of building insulation materials. In addition, use of the renewable composites could also reduce embodied greenhouse gas (GHG) emissions of the insulation materials. Local production and use of the composites could stimulate residential building insulation process via additional socio-economic benefits, such as positive impact on local economy, created workplaces and reduced import. The research question of this study is to determine a difference between embodied energy and GHG emissions of the mycelium insulation material and synthetic insulation alternatives. System dynamics model is used as the method for assessment of the dynamics of the total embodied energy and GHG emissions if equal amounts of the insulation materials is produced. Time horizon for the modeling is 2021–2050. Data used in the model were taken from scientific publications and laboratory experiments with growth process and properties of the mycelium composites. The model includes several feedback effects, e.g., effect of research and development on efficiency and productivity of the mycelium production process. The results show that embodied energy of the mycelium insulation material is higher than for the synthetic alternatives but the embodied GHG emissions are considerably lower than for the alternatives. The embodied GHG emissions are even lower if the absorption of CO2 of renewable materials used for the production of the mycelium composites is included.

Insulation Performance

Building designs should be reviewed from the aspects of both design aesthetics and energy performance. The installation of insulation materials in external walls, roofs, and floors is a basic method that could reduce energy losses from buildings. The purpose of this study is to investigate the types of insulation materials selected as building materials and the insulation performance of each building elements when designing new buildings in South Korea. The insulation performance of the external walls, roofs, and floors of buildings were compared with the insulation criteria of the Energy Saving Design Standards of Buildings in building energy code. The design documents, as well as drawings and building energy saving plan sheets, which are required to be submitted for buildings larger than a certain size in South Korea, were collected. The most widely used insulation material in multi-family housings and non-residential buildings was extruded polystyrene (XPS). The insulation performance of external walls, roofs, and floors were higher than that established by design criteria of building energy code. In particular, the external walls had roughly a 25.5% better insulation performance than the insulation criteria.

Thermal insulation materials are among the simplest ways of decreasing heat loss in the buildings. When insulation materials are installed in the walls, floors and roof of a building to prevent heat loss from the building, materials must be used with the appropriate structural and thermal properties. In this paper, a laboratory test of the thermal conductivity and cell structure of building insulation materials was conducted. From the experiment results, the correlation expression between thermal conductivity and density was derived. In the case of the insulation materials that were made of expanded polypropylene (EPP), as the density increased, the thermal conductivity tended to decrease; and in the case of ethylene-vinyl acetate co-polymer (EVA) and polyethylene (PE), as the density of the insulation materials increased, the thermal conductivity tended to also increase.

AbstractThe demand for natural insulation materials is increasing with special attention to the use of such materials for exploiting renewable energy. Natural insulation materials tremendously influence the sustainability development and energy efficiency enhancement in the buildings. Natural fibers from animal’s origin absorb great amount of moisture on exposed to the environment which significantly affects the performance and thermal insulation properties. The thermal degradation of such material strongly influences the accidental burning characteristics, an important selection criteria for building materials. In the present study, three different kind of natural insulation materials namely sheep wool, goat wool and horse mane have been characterized in terms of moisture absorption, thermal degradation and morphology using thermogravimetric analysis (TGA), differential scanning calorimetry techniques, and scanning electron microscopy, respectively. In addition, antibacterial behavioral study has been also carried out for untreated raw wool and treated wool (copper nitrate). These properties are vital for a holistic evaluation of the insulation material. Moisture absorption results indicate that the sheep wool and goat wool absorb less moisture content as compared to horse mane. Unlike this horse mane shows great stability than goat wool and sheep wool in the temperature range not exceeding 470 °C. TGA data indicate 50% mass loss (T50%) at 306 °C, 322 °C and 318 °C for sheep wool, goat wool and horse mane, respectively. In addition the tests show that the content of fire retardant elements like nitrogen and sulphur is more in horse mane as compared to sheep wool and goat wool. The treated wool samples showed excellent antibacterial properties as compared to untreated wool samples.

Operational Phase

The building sector is known to have a significant environmental impact, considering that it is the largest contributor to global greenhouse gas emissions of around 36% and is also responsible for about 40% of global energy consumption. Of this, about 50% takes place during the building operational phase, while around 10–20% is consumed in materials manufacturing, transport and building construction, maintenance, and demolition. Increasing the necessity of reducing the environmental impact of buildings has led to enhancing not only the thermal performances of building materials, but also the environmental sustainability of their production chains and waste prevention. As a consequence, novel thermo-insulating building materials or products have been developed by using both locally produced natural and waste/recycled materials that are able to provide good thermal performances while also having a lower environmental impact. In this context, the aim of this work is to provide a detailed analysis for the thermal characterization of recycled materials for building insulation. To this end, the thermal behavior of different materials representing industrial residual or wastes collected or recycled using Sardinian zero-km locally available raw materials was investigated, namely: (1) plasters with recycled materials; (2) plasters with natural fibers; and (3) building insulation materials with natural fibers. Results indicate that the investigated materials were able to improve not only the energy performances but also the environmental comfort in both new and in existing buildings. In particular, plasters and mortars with recycled materials and with natural fibers showed, respectively, values of thermal conductivity (at 20 °C) lower than 0.475 and 0.272 W/(m⋅K), while that of building materials with natural fibers was always lower than 0.162 W/(m⋅K) with lower values for compounds with recycled materials (0.107 W/(m⋅K)). Further developments are underway to analyze the mechanical properties of these materials.
