Abstract:

Various eco-friendly materials are used in the construction industry. South Korea employs the Green Standard for Energy and Environmental Design (G-SEED), a green building certification system, in which materials account for 11% of the evaluation criteria. However, data for each eco-friendly material are managed individually by different institutions, causing inefficiency, increased costs, and potentially greater environmental impacts associated with material and resource selection. Hence, this study develops a green building materials integrated platform (GIP) that collates information on eco-friendly materials across different industries in South Korea, to support the G-SEED evaluations. Guidelines and standards related to each evaluation item were analyzed and used to compile a green building materials database. The database includes 12,636 data points representing product prices and environmental impact data. This database was used to develop the four-level Excel-based GIP. Case studies were conducted on actual G-SEED buildings to analyze the economic efficiency and environmental performance achieved by using alternative materials to those recommended by the GIP. Case 1 exhibits improvements in economic efficiency and environmental performance of 17% and 10%, respectively, whereas Case 2 exhibits improvements of 8% and 21%, respectively. Thus, both case studies boast superior combinations of green building materials compared to existing alternatives.

Abstract:

Durable, renewable, and affordable are the three characteristics of the adobe brick, one of the widely used construction material in human civilization, but is always neglected. Traditionally, price has been the foremost consideration when comparing similar materials or materials designated for the same function. That is why by the post-war period, the concrete was adopted as a universal building material in response of the massive housing demand. The intergovernmental concerns never took into consideration both the sustainability factor and the cultural one, not until the 1990s when research on climate change expanded and the sustainable development took an important place in the different academic cross fields: engineering, biology, technology and architecture. The main focus by then was the reduction the CO2 gas emissions emitted by the building sector which is now approximately 30% of the global energy-related. Researchers are focusing on creating a completely new green eco-material an alternative to the concrete, but in this paper, I will demonstrate why is it worth to reinvigorate centuries-old eco-construction material. Adobe bricks are currently the best choice to built affordable housings in response to the chronicle demand. Not only they have a track record that makes their thermal mass performance easier to evaluate, but also they can last 400 years or more when properly maintained. Comparatively, new technologies require testing over time to determine their long-range effectiveness.

Abstract:

In recent years, the awareness of sustainable construction has increasingly risen in countries around the world, with the main goal being to avoid depleting energy resources and raw materials and to greatly reduce carbon emissions. Therefore, the selection of eco-friendly building materials becomes a difficult task and choosing the best construction strategy is a complicated process. Most of the studies of the building material selection often focus on optimizing material-related green building scores with budget constraints based on the environmental impacts of those materials. However, these studies do not pay attention to the impact of sustainable materials on two important aspects of a project: The initial investment cost and the total labor-working days. Hence, this study developed a model that optimizes a material mix for buildings considering the building budget, total labor-working days, and material-related green building scores. A case study in Vietnam was conducted to illustrate the effectiveness of the proposed model. This proposed model provides a guidance for decision-makers in selecting approximate materials for buildings toward sustainability.

Abstract:

Eco-friendly building designs that use building information modeling (BIM) have become popular, and a variety of eco-friendly building assessment technologies that take advantage of BIM are being developed. However, existing building environmental performance assessment technologies that use BIM are linked to external assessment tools, and there exist compatibility issues among programs; it requires a considerable amount of time to address these problems, owing to the lack of experts who can operate the programs. This study aims to develop eco-friendly templates for assessing the embodied environmental impact of buildings using BIM authoring tools as part of the development of BIM-based building life cycle assessment (LCA) technologies. Therefore, an embodied environmental impact unit database was developed, for major building materials during production and operating stages, to perform embodied environmental impact assessments. Moreover, a major structural element library that uses the database was developed and a function was created to produce building environmental performance assessment results tables, making it possible to review the eco-friendliness of buildings. A case study analysis was performed to review the feasibility of the environmental performance assessment technologies. The results showed a less than 5% effective error rate in the assessment results that were obtained using the technology developed in this study compared with the assessment results based on the actual calculation and operating stage energy consumption figures, which proves the reliability of the proposed approach.

Abstract:

In the building industry, decreasing the CO2 emission not only is an important environmental issue but also an international responsibility in the future. This research analyzed building life cycle CO2 emission and used a building life cycle CO2 emission index (LCCO2). LCCO2 allows us to compare the impacts of different building designs to the environment and finds out the most efficient CO2 reduction strategy. A low floor house life cycle simulation showed that most CO2 emission in the life cycle comes from the daily use stage. Therefore, energy preservation in the daily life is the most important strategy to reduce CO2 emission in a building. Compared with the RC house, the light weight steel house uses more eco-friendly building materials and heat preservation materials. Therefore, the LCCO2 of the light weight steel house is reduced 31.34%. The research also showed that proper increase in the life span of the building also decreases CO2 emission. The light weight steel house is more eco-friendly than the RC house in the buildings life cycle.

Abstract:

In the last 20 years, there have been a series of seismic events in Italy that have caused serious damage to civil and building structures. This has led to a significant increase in the use of concrete for the reconstruction of new structures and the repair of existing structures damaged by earthquakes. At the same time, the concrete industry is responsible for the most significant environmental damage during the life cycle of the built environment. The environmental disadvantages characterizing the concrete industry are related to the constant growth of the exploitation of natural aggregates. Therefore, it is necessary to use alternative and innovative aggregates that provide good concrete performance and lower environmental impacts. In this study, a very promising route from an environmental point of view is given by the use of artificial aggregates from industrial waste as substitutes for natural aggregates. An innovative low cost and energy saving granulation process has been employed to produce lightweight aggregates using fly ash from the incineration of municipal solid waste and ground granulated blast furnace slag. The final aim of this research is to demonstrate the environmental sustainability of artificial aggregates, through a comparison of three different mixtures.

Abstract:

The use of environmentally friendly building materials has experienced slow growth within the residential construction market due to higher cost and low availability of certified wood. The development of green building programs (GBPs) marked the beginning of the effort to adopt energy-efficient design guidelines and utilize eco-friendly renewable materials in structures. These programs were targeted at reducing environmental impacts by integrating eco-friendly materials into the design and construction of buildings, including promoting the use of environmentally certified wood products (ECWPs) harvested from sustainably managed forests. This research was designed to determine which attributes influence architects’ decisions to use environmentally certified wood products in residential construction projects and how this might influence their perceptions and use of green building programs. The results indicate that architects who have participated in a GBP were more likely to have used ECWPs. The material attributes that influence architects’ selection of materials are mainly related to economics and function as opposed to environmental friendliness. These results will help to inform and broaden the understanding of issues that influence the adoption and utilization of environmentally certified wood products, and identify some of the factors that can contribute to their continued growth in the U.S. marketplace.

Abstract:

The global warming is one of the most serious problems. The decrease of CO2 emissions in our daily life is an important subject today. Recently, an application of water retentive materials as a paving material has attracted a great deal of attention in Japan. This material is effective for reducing heat island phenomenon, which is also a recent problem in many cities in Japan. Water retained in the material during rainfall evaporates when heated by sunshine. The latent heat absorbed by evaporating water works to cool the surroundings. The water retentive ceramic products are expected to be useful for building materials as well as pavements. Several performances are required on the water retentive ceramics when it is used as building materials. Its cost and quality are the important factors. Porous ceramic materials formed by pressing without firing is one of ideal low cost and eco-friendly candidates. The porous ceramics is also expected to be produced from recycled ceramic materials. By optimizing its composition and forming method, a water retentive material with high performance was developed. The trial product had the properties as follows; fracture toughness: 1300N, bending strength: 175N/cm, water absorption: larger than 30%, and precision in size (length): +-0.5mm for 150mm. The product showed also enough frost resistance. In this paper, the fundamental properties of the porous ceramics prepared without firing are discussed with referring to the results of the field experiments.Another subject recently studied by several tile manufactures in Japan is the glazed tile with high solar reflectance. The exterior walls covered with such a high solar reflectance tile keeps the surface temperature of the wall lower under the strong sunshine of summer. It is effective against heat-island phenomenon. In this paper, the outline of the research results on visible and infrared reflectance of many kinds of glazes is also discussed.

Abstract:

Eco-friendly materials have been developed recently that have made it possible to significantly reduce the maintenance cost of buildings when they are appropriately used in renovation. Indeed, it became extremely important to consider the eco-friendly energy-saving effects on design alternatives during renovation. The present study proposes a framework for the optimum maintenance decision-making model for considering eco-friendly energy to help people interested in making decisions concerning renovation; it requires that both the environmental friendliness and economic feasibility of the target building be simultaneously considered. Several studies mainly cover the structural aspects for energy improvements based on innovation and technology. However, energy simulation in existing buildings needs some additional consideration regarding the economic analysis of energy savings and the recovery period of construction costs. A case study was conducted as a research method by utilizing the proposed framework, which aims to: (1) make energy simulations with different basic design assumptions; (2) perform the energy simulations through building information modeling (BIM) technology; and (3) analyze the economic feasibility of the alternatives. As a result, an alternative combination that can save the net maximum energy cost during the life cycle period and invest the lowest renovation costs has been recommended. Furthermore, effective guidelines were proposed on which items the building owner values, depending on his economic investment conditions in decision-making regarding the level of design, through a comprehensive review of the energy savings by design variable. It is expected that the research findings will be utilized in the decision-making process and for conducting further relevant research in future.

Abstract:

A review of the recent literature shows that the use of more sustainable, eco-friendly recycled waste materials made from natural biopolymers is an important step of the planning process to reduce the environmental impacts of traditional building materials such as cement and concrete products. This study introduces the application of maize starch in the production of a novel biodegradable construction material. The samples prepared in this investigation were formed by heating a mixture of different proportions of starch, water and sand. The structural properties, morphology and chemical composition of materials were investigated by scanning electron microscopy (SEM) coupled with thermal gravimetric analysis (TGA). The structural characteristics and morphology of the study material to a certain extent resemble natural sandstones, the most common type of sedimentary rocks. Based on the uniaxial compressive strength classification schemes, comparing with the brittle deformation behavior of natural rocks, it can be considered that this material behaves as a polymer - matrix composite with a ductile - thermoplastic mechanical behavior.

Abstract:

In recent years, the interest in reusing recycled fibers as building materials has been growing as a consequence of their ability to reduce the production of waste and the use of virgin resources, taking advantage of the potential that fibrous materials may offer to improve thermal and acoustic comfort. Composite panels, made of 100% wool waste fibers and bound by means of either a chitosan solution and a gum Arabic solution, were tested and characterized in terms of acoustic and non-acoustic properties. Samples with a 5 cm thickness and different density values were made to investigate the influence of flow resistivity on the final performance. Experimental results demonstrated that the samples had thermal conductivity ranging between 0.049 and 0.060 W/(m K), well comparable to conventional building materials. Similarly, acoustic results were very promising, showing absorption coefficients that, for the given thickness, were generally higher than 0.5 from 500 Hz on, and higher than 0.9 from 1 kHz on. Finally, the effects of the non-acoustic properties and of the air gap behind the samples on the acoustic behavior were also analyzed, proving that the agreement with absorption values predicted by empirical models was also very good.

Abstract:

Natural eco-friendly materials are widely discussed topic nowadays, especially in the context of the implementation of European legislation into national legislation and with the increasing demands on the energy efficiency of buildings. The majority of builders still prefer the classical artificial materials. One of the reasons is the lack of technical information, particularly in the field of building acoustics and fire safety, which would be demonstrated by appropriate research. The aim of this study is to compare the acoustic properties of selected structures based on natural materials which are based on research results and a series of measurements with conventional materials to demonstrate their competitiveness.

Abstract:

By and large, straw is not considered to be a building material, yet in comparison with traditional materials, building with straw bales is definitely more energy-efficient, eco-friendly, and low-cost; qualities that are desirable in sustainable buildings. This paper presents information on three different straw bales buildings at the Kerkenes Eco-Center, which is located in the village of Sahmuratli in central Anatolia, Turkey. The first of these was constructed with load-bearing straw bale walls; the second with straw bales as infill in a timber-frame structure; while the third utilized straw bales in combination with Autoclave Aerated Concrete (AAC) blocks. This last was a hybrid wall construction that has been tried for the first time to take advantage of the thermal-insulation property of straw combined with the humidity-regulating property of mud plaster inside and the weather-resistance property of AAC outside. These three buildings are being monitored for their temperature and humidity variances with the help of data loggers; this data is also presented herein.

Abstract:

The generation and use of energy are significant contributors to CO2 emissions. Globally, approximately 30% to 40% of all energy consumption can be directly or indirectly linked to buildings. Nearly half of energy usage in buildings is linked to maintaining the thermal comfort of the inhabitants. Therefore, finding solutions that are not only technically but also economically feasible is of utmost importance. Though much research has been conducted to address this issue, most solutions are still costly for developing countries to implement practically. This study endeavors to find a less expensive yet straightforward methodology to achieve thermal comfort while conserving energy. This study takes a broader view of multiple habitat-related CO2 emission issues in developing regions and describes a hybrid solution to address them. New technologies and innovative concepts are being globally examined to benefit from the considerable potential of PCMs and their role in thermal energy storage (TES) applications for buildings. The current study numerically investigates the thermal response of a hybrid building envelope consisting of PCM and local organic waste materials for low-cost low-energy buildings. The local organic waste materials used are those whose disposal is usually done by burning, resulting in an immense amount of greenhouse gases. In the first phase, different waste materials are characterized to determine their thermophysical properties. In the second phase, a low-cost, commonly available PCM calcium chloride hexahydrate, CaCl2.6H2O, is integrated with a brick and corn husk wall to enhance the thermal storage in the building envelope to minimize energy consumption. Temperature distribution plots are primarily used for analysis. The results show a marked improvement in thermal comfort by maintaining a maximum indoor temperature of 27 °C when construction is performed with a 6% corn husk composite material embedded with the PCM, while under similar conditions, the standard brick construction maintained a 31 °C indoor temperature. It is concluded that the integration of the PCM layer with the corn husk wall provides an adequate solution for low-cost and low-energy buildings.

Abstract:

Sustainability is currently an important part of the building industry. The development of new building constructions and the use of ecological materials is a very popular topic in this area. One example of organic material are natural fibres bio-composites. Bio-composite materials are currently used in the form of laminates mainly used in the sport and furniture industries. This article addresses their use in the building industry as the outer envelope of buildings. The article deals with the testing of the influence of UV radiation and moisture on the degradation of Bio-composites with recommendation of possible ways of their protection. In the next section, it deals with the design of composite wall panel with Bio-composite laminates on the top layer. This panel will contain mycelium as thermal insulation. The assumption of the use of this type of construction in the building industry is based on the possibility of replacing conventional materials used nowadays and reducing the environmental load by the building industry. The use of new types of eco-friendly building materials is in accordance with the EU strategy.

Abstract:

The concept of sustainable housing has considered the urgency to support the sustainable environment in an integrative way. This concept is related to several main principles include environmental, social, and economic sustainability. In practice, these principles translated into the fundamental of housing choice, both process and product choices. In many peri-urban areas, current house construction tends to imitate city houses with massive concrete structures equipped with air conditioning that caused high energy consumption. The Center for Rural Empowerment team of ITB built a prototype of an eco-friendly house in Haurgombong village, Sumedang, West Java. The house has two floors building on a 7x5 m2 land site. The first floor was renovated from the existing toilet rooms and develop into a two-floor house. The second floor was built using the local wood material. The wood material has been obtaining from the trees of seven years old beechwood (Gmelina Arborea) planted in the garden. The envelope material for this house was constructed from local and common material in rural or peri-urban context, the lightweight fiberglass for the roof of common room, and the transparent fiber materials for the roof of second-floor terrace to make the plantation at this area can easily receive the sunlight. This house is also can be regarded as a prototype of an earthquake-resistant house. The lighting factor, temperature, and airflow settings are made naturally. Besides, this house has also equipped with a rainwater storage system and greywater treatment using a small, constructed wetland that allows the treated water used for watering gardens and fishponds. The budget spent to build this house was as low as possible so that the surrounding community can imitate the building for their house and disseminate eco-friendly housing.

Abstract:

Concrete is the most important building material in construction industry because of its revolutionary property of quick hardening and free from internal problems. Its use has a great effect on environment due to the large amount of natural resources and cement lime materials required for manufacture the concrete structures. Now it’s the time for think in the direction of Eco-friendly durable materials in concrete production. In the present work, Quarry Dust and Foundry Sand are partial replaced River Sand to develop Rheological and Durability properties of M40 grade of Eco-Efficient Self-Compacting Concrete (ESCC). The target strength could be achieved satisfying the rheological properties of Eco-Efficient Self-Compacting Concrete with fiber additions. In this study investigations carried to find the Permeability, Shrinkage, Acid attack and Rapid Chloride Permeability Test (RCPT) of Eco-Efficient Fiber based Self-Compacting Concrete and it is observed that it is no way inferior to the conventional concretes. From the experimentation, it is recommended that waste materials from different source are fitting to be used as fine materials in concrete. The construction cost reduces by utilising such waste as fine aggregate in place of aggregate from natural source for construction.

Abstract:

The use of an airtight frame in low-energy buildings could increase the risk of health-related problems, such as allergies and sick building syndromes (SBS), associated with chemical emissions from building materials, especially if the ventilation system is not functioning properly. In this study, the indoor air quality (IAQ) was investigated in newly built low-energy and conventional preschools by monitoring the indoor air temperature, relative humidity, particle-size distribution and levels of carbon dioxide (CO2), nitrogen dioxide (NO2), formaldehyde and total volatile organic compounds (TVOC). The thermal comfort was satisfactory in all preschools, with average indoor air temperature and a relative humidity at 21.4°C and 36%, respectively. The highest levels of TVOC (range: 130–1650 µg/m3 toluene equivalents) and formaldehyde (range: 1.9–28.8 µg/m3) occurred during the first sampling period associated with strong emissions from building materials. However, those preschools constructed with environmental friendly building materials (such as Swan Eco-label) had lower initial TVOC levels compared to those preschools constructed with conventional building materials. The IAQ and indoor chemical emissions were also strongly dependent on the functioning of the ventilation system. Preliminary risk assessment indicated that exposure to acrolein and crotonaldehyde might lead to respiratory-tract irritation among occupants.

Abstract:

The most basic and primary building material for construction of houses is the conventional brick. The rapid growth in today’s construction industry has obliged the civil engineers in searching for more efficient and durable alternatives far beyond the limitations of the conventional brick production [1-2]. A number of studies have been made and serious steps have been taken in manufacturing of bricks from several waste materials. However, the traditional mean of bricks production which has brought hazardous impacts to the context has not yet been changed or replaced by more efficient and sustainable one [3], [4]. Most of the researches went through enhancing the clay brick quality and properties by mixing the clay with various recycled wastes as foundry sand, granite sawing waste, harbour sediments, perlite, sugarcane, baggase ash, clay waste and fine waste of boron, sewage sludge, waste glass from structural wall and other different wastes. Compile this state of the art work of manufacturing bricks in the past and the current trend in the bricks industry with respect to the raw materials, ways of manufacturing and the out- comings.This project presents an experimental study on the utilization of waste materials which replaces clay with (Plastic covers, Ceramic Powder, Egg Shell Powder, GGBS, Silica Fume, Rice Husk Ash and Lime Powder) and Fine Aggregate with (Recycled glass, Dry Grass, Dead Leaves, Tree barks powder, Sugar cane powder, crumbed rubber) to produce eco-friendly Bricks. This project is an attempt to fill the gap of the past studies and suggest more sustainable and sophisticated methods of brick manufacturing in the future. 40 percent replacement of fine aggregate with crumbled rubber and dry grass in mortar bricks have given encouraging results, also the replacement of cement by egg shell powder at 20% has given a considerable result

Abstract:

Concrete is the most widely used building component in the world due to its versatility, low cost and durability. Most common coarse aggregate used in the construction are stones which is obtained from quarry. The demand for coarse aggregate in the construction industry has consequently increased due to the extensive use of natural resources. It has necessitated research into alternative materials of construction. This research aims to find the alternate material for coarse aggregate by using Ground Granulated Blast furnace Slag (GGBS) clinker and to determine the hardened properties of non-conventional concrete in M20 Grade. The aggregate utilized in this work is an Eco friendly material, which replace the conventional coarse aggregate to preserve the depletion of natural resources. It is abundantly available than the conventional aggregate and reduce pollution. This paper focuses on investigating characteristics of concrete with replacement of coarse aggregate by GGBS Clinker. This study deals with the GGBS clinker advantages and limitations in concrete. The usage of GGBS clinker serves as a replacement of conventional aggregate to reduce the depletion of conventional building materials. It serves as an Eco friendly way of utilizing the by- product without dumping it on ground.

Abstract:

The conventional building material used in the construction industry in India is the burnt clay brick which has high embodied energy (1.4W/m K). It causes significant environmental hazards as it consumes considerable amount of top soil. Hence there is a need to produce environmentally responsive building materials for the construction of new buildings in order to meet the rapid urban growth. As an alternative, natural resources used in conventional building material can be replaced by industrial and agricultural wastes like fly ash, copper slag and phosphogypsum, slag to address and solve socio-economic problems such as employment, shortage of residential spaces while ensuring the economic feasibility. This paper thus attempts to identify an eco-friendly alternative building material by utilizing wastes from industrial & agricultural sites as partial substitutes of sand, cement or aggregates, thereby reducing continuous exploitation of these natural resources. . The properties of the alternative building wall materials are identified and compared with that of conventional bricks. Additionally the thermal conductivity of the proposed block is determined and compared with that of brick to provide a comfortable building environment for the end user.

Abstract:

The use of ammonium polyphosphate (APP) and expanded graphite (EG) as a flame retardant for polymer generally requires a relatively high amount of addition to achieve a flame-retardant effect, and is liable to cause a decrease in strength of the material. Therefore, in this study waste diatomite was used as an eco-friendly flame-retardant for high density polyethylene (HDPE) to reduce the amount of APP and EG and can reach the flame-retardant level. Moreover, the waste diatomite was heat treatment and surface modified by silane coupling agent to improve its compatibility with HDPE. The results show that the tensile strength of the HDPE drops sharply after the addition of the APP and EG. However, replace some of the APP and EG by the modified diatomite can slow down the decline and maintain the basic physical properties of the material. The impact strength of HDPE was also decreased by the addition of APP, EG and untreated diatomite. However, the impact strength of HDPE was increased after adding the surface modified diatomite. It can be seen from the experimental results that the addition of the waste diatomite modified by the silane coupling agent can reduce the usage of the flame retardant such as APP and EG, and increase the strength by increasing the compatibility between the plastic and the inorganic material. Moreover, this eco-friendly formulation can reach the UL-94 HB level, and it can be applied to interior decoration or as building materials in the future. Thus, it can not only recycle the wastes, but also reduce the threat caused by fire.
