A novel ultra-light bio-based fiberboard from mexican feather grass for thermal and acoustic insulation in green building construction applications

The use of natural fibers as raw materials for insulation fiberboard production is emerging as a strategy to replace wood fibers. This study developed an ultralightweight natural fiber insulation core fiberboard (CFB) with high mechanical strength, hygroscopic resistance, and excellent acoustic and thermal insulation properties. This study examined the production of CFB, which utilizes Mexican feather grass fibers with an epoxy resin binder across a range of densities of 0.18–0.36 g∙cm−3. Furthermore, the impact of incorporating a reinforcing skin layer of woven glass fibers on the core fiberboard's physical, mechanical, acoustic, and thermal properties was evaluated. All the fiberboard samples exhibited excellent thermal conductivity values (0.048–0.057 W/mK), which increased with increasing panel density (0.18–0.36 g∙cm−3). In addition, all of them displayed superior mechanical properties following the ASTM C208 standard. In terms of climatic resistance of the fiberboards, the results displayed excellent water resistance, exhibiting minimal humidity content (<5 %), thickness swelling (<6.5 %), and a hydrophobic surface, as indicated by the high-water contact angle (>121.96 at 30 s). Sound reduction exhibited a frequency-dependent tendency, with denser and sandwich fiberboards showing greater sound reduction of up to 27.9–36.56 dB at 3150 Hz for CFB-0.36 and SFB-0.52, respectively. Following ASTM C208, both core fiberboards and those coated with woven glass fiber skins (sandwich fiberboards, SFB) met the thermomechanical property requirements for regular and structural wall sheathing applications, respectively. These findings highlight the potential of Mexican feather grass as a bio-based alternative to wood, enabling the production of eco-friendly ultralightweight fiberboards with excellent thermomechanical properties suitable for building construction, such as regular and structural wall sheathing applications and ceiling decorations.

Research on Coupling Effect Measurement and Coupling Risk Simulation of Green Building Construction Safety Risk Factors

The construction of green buildings is an important direction for the transformation and development of the construction industry, but it is beset with problems such as a lack of construction experience, immature new technologies, and unstable material properties; these issues bring risks to the construction stage of green buildings, and the coupling of uncertain risk factors in the construction process of green buildings may lead to unfavorable results. The purpose of this study is to explore the coupling degree of green building construction safety risk factors and the changing trend in their coupling combinations at the system risk level. First, the risk factor index system was defined by reading the literature and gathering expert opinions, and the coupling degree between risk factors was measured using an improved coupling degree model. Then, a system dynamics model was established to simulate and analyze the coupling effects among the risk factors and determine the combinations with the greatest influence. The results show that the risk probability is proportional to the risk coupling value, the human–environment coupling value is the largest, and the material equipment–management coupling value is the smallest. The human–environment system simulation shows that reducing the coupling value of system factors will promote a decrease in the total level of system risk. According to the research conclusions, measures to prevent risk coupling are proposed, which offer theoretical references for green building practitioners carrying out risk management; these measures hold a certain guiding significance for the risk control and future development of green buildings.

Green Building and Energy-Efficient Design

In the modern era, the rapid expansion of infrastructure is a crucial indicator of a country's development. However, this growth must be balanced with environmental conservation to ensure the well-being of humans and other living organisms. The construction industry, a significant development driver, is also a primary source of environmental pollution, contributing to approximately 40% of air pollution. The production and transportation of construction materials, particularly cement and steel, are primary culprits. These processes release substantial amounts of CO2, a greenhouse gas that deteriorates the ozone layer and exacerbates global warming. Cement production accounts for 8-10% of global anthropogenic CO2 emissions, while steel manufacturing contributes about 5-10%. These emissions harm the environment and adversely affect human living conditions. Although it is challenging to eliminate CO2 and other greenhouse gas emissions, adopting sustainable living practices, such as the construction of green buildings, offers a viable path toward mitigation. Green or sustainable buildings are designed, constructed, operated, and maintained to minimize adverse environmental impacts and promote occupant health and well being. These structures aim to reduce resource consumption, increase energy efficiency, improve indoor air quality, and decrease the overall environmental footprint compared to traditional buildings. By prioritizing Sustainability, green buildings present an effective strategy to address the ecological challenges the construction industry poses, paving the way for a more sustainable and harmonious relationship between development and the natural world.

Exploring the Barriers to Managing Green Building Construction Projects and Proposed Solutions

Sustainability has gained importance in the building design/construction industry due to the increase in the need for energy, the extensive use of non-renewable resources, and therefore the damage caused to the environment by traditional building design and construction. The concept of green building was developed for this reason. Green buildings can be defined as structures that consume less water, energy, and other resources while emphasizing human health and protecting the environment. While green buildings have these advantages over traditional buildings, the rate of green building production is less than expected because many barriers are encountered during the design and production of green buildings, despite the recent attention paid to sustainable practices. This research focuses on exploring the barriers encountered during green building production in Turkiye and the possible solutions for overcoming these barriers. According to the data obtained through a questionnaire survey, the most important difficulties encountered in Turkiye include the lack of government subsidies, the lack of green building regulations, the public’s indifference to green building technologies, and education and technology deficiencies. According to the respondents, the possible solutions involve government incentives, adoption of national standards and best practices, educating the public and the design/construction professionals about green buildings, and the development of novel green building technologies. The major contribution of the findings is that it highlights the fact that the stakeholders of green building projects (i.e., owners, designers, constructors, and facility managers) face important barriers and lets stakeholders recognize that solutions to overcome these barriers are available. The major implication is that the stakeholders in green building projects will likely be better prepared to deal with any barrier before undertaking green building projects in Turkiye and countries with similar socio-economic conditions.

Opportunities of building tall and green – an overview from a European perspective

The purpose of the article is to answer the question of whether a tall building, throughout its entire life cycle, can be sustainable. A literature review and online searches were conducted in order to gather data on the impact of environmental trends on chosen aspects of tall European building design. The conducted analyses confirm the hypothesis that the European approach considers sustainable aspects and can be the basis for general guidelines for the construction of green tall buildings, ensuring that the tall building’s location, floor areas and heights are functionally justified. Despite the demanding climate conditions, high-rise buildings are designed using bioclimatic solutions and take the use of passive phenomena and a reduction in the operating time of mechanical systems into account. The necessary technical infrastructure uses highly efficient, energy-saving equipment and solutions. Obtaining energy from renewable sources is present in architectural solutions but not very popular – these technologies are still growing and gaining importance.

Reducing betrayal behavior in green building construction: A quantum game approach

The issue of energy consumption in buildings is becoming increasingly pertinent. Society highly values energy conservation and environmental protection, viewing the adoption of green buildings as an inevitable trajectory in the evolution of the construction sector. However, a challenge emerges during the progression of green building construction concerning betrayal within the supply chain. This paper employs a quantum game approach to tackle the issue of green building betrayal within a two-tier green building supply chain comprising developers and contractors. Initially, a non-zero-sum classical game model is formulated based on the green-building construction process between developers and contractors Subsequently, the classical strategy space is extended to the quantum strategy space. The findings indicate that in classical games, and without considering quantum entanglement, even if both parties adopt comprehensive strategies, the party exerting complete effort still faces the risk of betrayal. Conversely, in scenarios of maximum quantum entanglement, the loss incurred by the party not exerting complete effort does not affect the party making a complete effort. Consequently, when accounting for quantum entanglement, both parties tend to opt for complete effort. Lastly, an entanglement treaty is proposed to constrain the strategic choices of both parties and ensure that neither has an incentive to betray. The findings of this study provide good suggestions for green building project managers to improve the effort degree of the developer and general construction contractor in green buildings to promote the development of green buildings.

Participants were asked to rate their knowledge, understanding, and importance of the eight withholding factors and six contributing factors identified in the seminal literature. We use analysis techniques like descriptive and factor analysis such as descriptive and factor analyses to analyse the survey responses. A comprehensive model proposed to facilitate the purpose of promoting the successful adoption of green building practises within India's public sector construction projects was primarily based on the insights gained from factor analysis. Based on the findings of this study, the author suggests a model for implementing green building techniques in Indian public sector constructions. The model discusses obstacles to green building initiatives, considers implementation variables, and offers suggestions such as policy ease, and green building promotion.

Effect of titanium dioxide on fresh and mechanical properties of Mortar: A review

Nanotechnology-based engineering approaches are rapidly developing throughout the world. Modern, cutting-edge nanotechnology has proven useful in a variety of technical applications. In emerging and developed countries, increasing infrastructure needs a considerable amount of cement, which has a significantly impact on the environment and human health, resulting in greenhouse gas emissions and severe acute respiratory illnesses (asthma and silicosis, respectively). To overcome such difficulties, cement consumption in building materials must be reduced. Several novel extra materials have lately been introduced to improve the performance of mortar. Nano-titanium dioxide (NT) in cement mortar is widely used in green building construction because NT capable to the degradation of air pollution, self-cleaning, and enhancing mechanical, microstructural, and durability properties. In this paper, the effect of NT on fresh and hardened properties of cement mortar has been discussed. For the collection, screening and implementation of data for review paper PRISMA analysis and VOSviewer technique was used. Existing literature indicates that the reduction in workability 15% − 20% whereas improvement in compressive strength (CS) up to 15% and tensile strength up to 45% was noted with NT in mortar. Current research supports using NT as a cement replacement in mortar. Aside from the key findings, some identified gaps, problems, and future scope challenges have been presented in order to develop NT based mortar as a sustainable material in the building sector.

SUSTAINABLE MATERIALS IN CONSTRUCTION

The construction industry is one of the largest exploiters of both renewable and non- renewable natural resources. It was inevitable that it would find itself at the centre of concerns regarding environmental impact. The process and operation of building construction consumes a great deal of materials throughout its service life cycle. The selection and use of sustainable building materials play an important role in the design and construction of green building. This chapter sets out to present an overview of sustainable building materials and their impacts on the environment. Materials used for the structure of buildings require properties of strength, whereas other parts, such as the envelope, are selected for their insulation or aesthetic properties. Comparisons become more complex when materials perform more than one function such as load-bearing walls that provide good thermal insulation. There is also a need to distinguish between finite resources and renewable resources when reviewing the sustainability of a material. Some materials, despite being non-renewable may be considered plentiful on earth; however, the consequences and impacts of mining them may be considered unacceptable. The effect of construction material selection will impact upon sustainability throughout the lifetime of both the material and that of the building itself. The need to maintain the building, replacing individual components, disposing of the old, and procuring the new will have environmental impact from cradle to grave.
