The developments of thermally sprayed coatings for steel structure protection were described. Based on Al, Zn, Zn-Al and Zn-Al-Mg coatings, the anti-corrosion properties of new-pattern Zn-Al-Mg-RE coating were evaluated through electrochemical methods including electrochemical polarization and electrochemical impedance spectroscopy (EIS) coupled with SEM and XRD. The models of Zn-Al-Mg-RE coating undergoing corrosion with the initial pinhole defect and the latter with accelerated products were also discussed. The results show that Zn-Al-Mg-RE coating exhibites excellent corrosion resistance for long-term immersion, which is helpful for the sustainable design of steel structure in aggressive corrosion conditions. And the corrosion products seem to possess certain self-sealing function.展开更多

Today, there is an increasing need for sustainable building design. Besides, BIM （building information modeling） is one of the most noteworthy developments in construction industry. BIM is used to make the planning, design, construction, and operation process more integrated. The purpose of this paper is to survey application of BIM in sustainable building design. This exploration is done by reviewing the existing studies in the field of BIM and sustainable design. There have been few attempts to evaluate and analyze the benefits of BIM in sustainable design, and existing researches have not developed integrated analysis to evaluate different aspects of BIM application. In this study, BIM and sustainable design researches are categorized into some major areas. First, frameworks and design strategies for better implementation of sustainable design have been developed. Other application of BIM software is for improving sustainable design in which some case studies have been presented for this purpose. Another major area is focusing on a specific aspect of sustainable buildings such as using natural resources, energy simulation, daylighting analysis and carbon emissions. Scrutiny review of the current studies shows excellent potential for interaction of BIM with sustainable construction.展开更多

The aim of this paper is to develop the guidelines that could be applied in the design of a space structure in order to achieve the optimal overall lifetime performance of the space structure. Space structures are more than inanimate hunks of metal, glass and fabric. Every space structure that we design as structural engineers is like a child - a child that is conceived with a passionate vision of its form, structure and purpose; nurtured through the schematic design phase and the development of construction documents; and cared for during the labor pains of plan check corrections, requests for information, shop drawing review, and construction observation. Like children, our space structures mature, perform necessary functions during their lives, and eventually, grow old and die. The design of a sustainable space structure is a much more challenging and cross-disciplinary process than in the past and therefore it is necessary that the space structure is viewed as an integrated system and that all members of the design team work in a fully integrated fashion.展开更多

However, poor design of driver’s workplace is a major risk factor responsible for the uncomfortable conditions which operators of this highly technological system are exposed to especially when engaged in long distance driving. This study aimed at developing anthropometric model for business bus drivers in Nigerian which would facilitate sustainable design of driver’s workplace. A sample size of 161 drivers was randomly selected among strata of operators of buses in selected motor parks in the study area for the ergonomic study. Twelve anthropometric data were collected and analysed to obtain their 5th, 50th and 95th percentiles with which the anthropometric model were developed. Anthropometric model developed from 1932 data points was presented in forms of table showing measurement of sitting driver’s body parts in his workspace indicating design for average as well as extremities of 5th and 95th percentiles. The model represents a database from which designers, manufacturers of equipment, machine, automobiles and household goods can obtain relevant body measurement of the population under study in relation relevant to specific product feature and for development of sustainable workspace design.展开更多

The selection of the project delivery method (PDM) is extremely important in the effective execution of the project, and plays a critical role in establishing communication and coordination between the key entities: owner, architect, and contractor. The goal of this paper is to hopefully serve as a starting point for further discussion to improve on the AEC industry’s current integration of sustainability principles in PDMs. The first step consists of an assessment of current project delivery systems from a sustainable design perspective. This is followed by a determination of the current limitations, and examination of the various disrup-tions in the industry. Various literature sources are analyzed to form a framework to discuss improvements and optimization strategies beyond the current system. Thereafter, proposed solutions are introduced at both stakeholders, as well as PDM scales. In this paper, the focus for the conducted analysis and proposed method-ologies is predicated on new construction projects instead of retrofits due to the resources available. However, the principles can similarly be applied to retro-fit scenarios as well, depending on the specific requirements of the individual project at play.展开更多

The theory of open-plan housing is able to provide a more flexible and adaptive space for the users and bring sustainable and economic benefit in the way of making full use of construction materials. Sustainable architecture design, as a method to respond the phenomenon, is able to low down the building＇ s energy consumption and has enormous potentials in creation of sustainable living environment and a high-quality dwelling condition. The primary aim of this research is to create a new sustainable architecture design method for occupancy by integrating openplan housing theory and application of sustainable technologies. Numerical simulation by computer program is applied in order to investigate and evaluate the possibility of this method in teruas of improving indoor comfort level and energy-saving capacity.展开更多

文摘This case study investigated employees’work performance and satisfaction in relation to sustainable design criteria used to design the interior of their office building.The case study is part of ongoing research to continue testing a questionnaire for validity and reliability,which will contribute to the development of sustainable design/occupant scales relating to satisfaction and performance.A self-administered,Internet-based questionnaire was developed that reflects a set of recognized sustainable design guidelines.It was submitted to over 200 employees of a business housed in a newly built office building in a mid-western city.Generally positive results were found for employees’satisfaction with the new facility(site,building,and interior)and their performance as related to sustainable design criteria in the new facility.Dissatisfaction with acoustic and privacy conditions were found for employees of open-office workstation types(cubicles).Exploration of prior workstation types showed that moving from private offices to cubicles decreased employees’satisfaction with new cubicles compared to moving from cubicles in a prior building to cubicles in the new building,though dissatisfaction with these two criteria was found despite prior workstation type.These findings concur with other sustainable design studies and demonstrate that the questionnaire can be used by sustainable designers to document and explore design outcomes.

文摘Polymer nanocomposites have a great potential to be a dominant coating material in a wide range of applications in the automotive,aerospace,ship-making,construction,and pharmaceutical industries.However,how to realize design sustainability of this type of nanostructured materials and how to ensure the true optimality of the product quality and process performance in coating manufacturing remain as a mountaintop area.The major challenges arise from the intrinsic multiscale nature of the material-process-product system and the need to manipulate the high levels of complexity and uncertainty in design and manufacturing processes.In this work,the challenging objectives of sustainable design and manufacturing are simultaneously accomplished by resorting to multiscale systems theory and engineering sustainability principles.The principal idea is to achieve exceptional system performance through concurrent characterization and optimization of materials,product and associated manufacturing processes covering a wide range of length and time scales.Multiscale modeling and simulation techniques ranging from microscopic molecular modeling to classical continuum modeling are seamlessly coupled.The integration of different methods and theories at individual scales allows the quantitative prediction of macroscopic system performance from the fundamental molecular behavior.Furthermore,mathematically rigorous and methodologically viable approaches are pursued to achieve sustainability-goal-oriented design of material-process-product systems.The introduced methodology can greatly facilitate experimentalists in novel material invention and new knowledge discovery.At the same time,it can provide scientific guidance and reveal various new opportunities and effective strategies for achieving sustainable manufacturing.The methodological attractiveness will be fully demonstrated by a detailed case study on the design of thermoset nanocomposite coatings.

文摘Building owners,designers and constructors are seeing a rapid increase in the number of sustainably designed high performance buildings.These buildings provide numerous benefits to the owners and occupants to include improved indoor air quality,energy efficiency,and environmental site standards;and ultimately enhance productivity for the building occupants.As the demand increases for higher building energy efficiency and environmental standards,application of a set of process models will support consistency and optimization during the design process.Systems engineering process models have proven effective in taking an integrated and comprehensive view of a system while allowing for clear stakeholder engagement,requirements definition,life cycle analysis,technology insertion,validation and verification.This paper overlays systems engineering on the sustainable design process by providing a framework for application of the Waterfall,Vee,and Spiral process models to high performance buildings.Each process model is mapped to the sustainable design process and is evaluated for its applicability to projects and building types.Adaptations of the models are provided as Green Building Process Models.
文摘Sustainability principles have become an integral part of the design and construc-tion process for many new construction projects. The selection of the project delivery method (PDM) is extremely important in the effective execution of the project, and plays a critical role in establishing communication and coordination between the key entities: owner, architect, and contractor. The goal of this paper is to hopefully serve as a starting point for further discussion to improve on the AEC industry’s current integration of sustainability principles in PDMs. The first step consists of an assessment of current project delivery systems from a sustainable design perspective. This is followed by a determination of the current limitations, and examination of the various disrup-tions in the industry. Various literature sources are analyzed to form a framework to discuss improvements and optimization strategies beyond the current system. Thereafter, proposed solutions are introduced at both stakeholders, as well as PDM scales. In this paper, the focus for the conducted analysis and proposed method-ologies is predicated on new construction projects instead of retrofits due to the resources available. However, the principles can similarly be applied to retro-fit scenarios as well, depending on the specific requirements of the individual project at play.
文摘We have the tools and the knowledge to create much healthier,economical,and ecologically responsible buildings at little or no incremental cost over that of conventional buildings.Unfortunately,both actual and perceived financial barriers are preventing widespread adoption of sustainable design,construction,and maintenance practices.Often organizations express a commitment to sustainable design and construction,but limit the actual implementation to only low-hanging fruit and ignore any significant investment.We need to be able to explain the benefits of sustainable design,construction,and facilities management in a more compelling fashion.In addition to talking about important features of green building,such as decreased use of energy,water,and other natural resources,we need to emphasize the benefits of green building in terms that resonate with key decision makers,such as higher net profits,increased asset values,enhanced image and reduced risk.This article provides useful information that could help you address some barriers to sustainable initiatives:•Every executive that you speak to is aware that data can be manipulated and may be skeptical of studies conducted by organizations that could benefit from a particular set of results.So I’ve included information on independent third-party studies.•In challenging economic times,people are particularly concerned about short-term cash flow.So I’ve included information on programs developed by the Building Owners and Management Association(BOMA)International to maximize asset values without sacrificing shorter-term profits.•Often people are risk-averse and feel more comfortable in the middle of the pack than on the cutting edge.So I’m including information on some potential risks of not going green,including decreased asset values and increased operating costs.Many aspects of sustainable design and construction are based upon proven technology and are being increasingly incorporated into best practices for the design and construction industries,which might lead to legal problems for those who do not include the more widely accepted sustainability measures in their projects.It can be difficult to find and navigate through existing incentives for energy efficiency.So I’m including information on a tool to help you find what initiatives are available and some expert advice on how to use this type of tool.•Often an executive may be far more concerned with the next quarter’s financial results than in the long-term profitability of an organization that he or she may very well not be working for in 20 years.Currently accepted financial accounting methods encourage this short-term focus.So I’m including information on the efforts of leaders in the finance sector to change accounting principles to accommodate considerations of long-term profitability.•Normally,people tend to accept the opinions of acknowledged leaders in their own fields.So I’m including examples of how sustainable initiatives are contributing to the bottom lines of several highly respected organizations.I’m also including information about efforts to create a globally accepted framework for accounting for sustainability that brings together financial,environmental,social,and governance information in a single integrated reporting format by a coalition including the Big Four accounting firms-PricewaterhouseCoopers,Deloitte Touche Tohmatsu,Ernst&Young and KPMG.
文摘With the increasing requirement of a higher living quality and the growing awareness of energy saving, how to improve the indoor comfort level and to reduce the expenditure of energy and slow down the rate of natural resource consumption is becoming increasingly important. The theory of open-plan housing is able to provide a more flexible and adaptive space for the users and bring sustainable and economic benefit in the way of making full use of construction materials. Sustainable architecture design, as a method to respond the phenomenon, is able to low down the building＇ s energy consumption and has enormous potentials in creation of sustainable living environment and a high-quality dwelling condition. The primary aim of this research is to create a new sustainable architecture design method for occupancy by integrating openplan housing theory and application of sustainable technologies. Numerical simulation by computer program is applied in order to investigate and evaluate the possibility of this method in teruas of improving indoor comfort level and energy-saving capacity.
文摘The COVID-19 pandemic in 2020 sparked a new awareness of fundamental human needs,bringing mental health to the forefront as a global priority.Social isolation and the abrupt shift in daily routines revealed how environments directly impact physical and emotional well-being.In this context,Neuroarchitecture emerged as an innovative solution,applying neuroscience principles to spatial design in order to enhance quality of life.This field studies how elements such as color,lighting,acoustics,layout,and natural features affect the brain and emotions.These parameters guide the creation of spaces that reduce stress,increase productivity,and foster a sense of comfort.Within the scope of biophilic design,strategies such as the use of natural light and the arrangement of areas that encourage social interaction have proven effective.With the rise of remote work and the growing value placed on functional homes,Neuroarchitecture has gained significance,demonstrating that well-designed environments can improve mental health.Businesses,schools,and hospitals have also begun adopting these concepts,creating more welcoming and efficient spaces.Therefore,the pandemic accelerated a transformation in how spaces are inhabited and designed,underscoring that architecture and psychology must go hand in hand.Neuroarchitecture is not just a trend,but a necessity in a world seeking balance between functionality and well-being.
文摘The integration of academic research methodologies into design thinking processes presents a transformative approach to addressing complex challenges in group housing,fostering inclusive,sustainable,and user-centered solutions.This research explores how methodologies such as Participatory Action Research,post-occupancy evaluations,and Research through Design can be systematically embedded within design thinking to bridge the gap between academic rigor and empathy-driven,iterative design practices.By synthesizing these paradigms,the study proposes a framework for group housing design that prioritizes co-design processes,empathy-based data collection,and participatory evaluation,while emphasizing adaptability through sociocultural insights and user feedback.Case studies analysis demonstrate the effectiveness of flexible,community-driven design,while emerging technologies like IoT-enabled cohousing signal new opportunities for innovation.Challenges,including scalability,long-term validation,and reconciling user autonomy with professional expertise,are critically analyzed.Ultimately,this research advances a hybrid methodology to redefine the conceptualization,implementation,and assessment of group housing,offering actionable pathways to achieve affordable,inclusive,and context-sensitive housing solutions.
