Urbanization has led to the rapid development of the construction industry.However,this has also led to higher requirements for the construction engineering management.Other than the quality monitoring of engineering construction,the energy-saving properties of the building should also be considered.Therefore,a scientific management approach should be adopted to improve green building management.This paper primarily examines the importance of quality management in green building construction,along with the factors influencing it.It also identifies the quality issues present in current green building construction.Finally,it proposes measures for quality management in the green building construction process to facilitate the industry’s healthy development.

A COST-BENEFIT ANALYSIS OF GREEN BUILDINGS WITH RESPECT TO CONSTRUCTION WASTE MINIMIZATION USING BIG DATA IN HONG KONG

It is generally accepted that the extra construction costs involved in the construction of green buildings will result in benefits including lower operation costs,higher sale/rental prices,and better sustainability performance.However,there has been little recognition of construction waste minimization(CWM)as one of the important benefits of sustainability performance as designated in green building.is paper aims to provide a better understanding of the cost benefit of green buildings with respect to CWM by using big data in the context of Hong Kong.The study is innovative in that it conducts a cost-benefit analysis specifically on CWM of green buildings by mining large-volume datasets.A surprise finding is that Hong Kong’s green building rating system(GBRS),i.e.the BEAM Plus,has a negligible effect on CWM,while it generally increases construction costs by approximately 24%.Hence,the increased construction cost of green buildings cannot be offset by CWM if corresponding items in the BEAM Plus are not properly incentivized.is paper demonstrates the necessity of emphasizing CWM-related items in GBRSs and of taking appropriate measures to deal with them.It also provides better decision-support information on the increased construction costs and the attainable benefits of green building that developers may wish to consider when initiating a green building project.

Orthogonal experiment on reclaimed water treatment and economic optimization model in green building

The efficacy of superior drainage in green building treated by combinational technique of coagulation sedimentation and constructed wetland was launched. The results show that the regression equation relating to effluent BOD5,cubage load (Nv),temperature (t) and addition dosage (ρ) is BOD5=2.05Nv-0.41t-0.82ρ+38.9. The orthogonal experiment results of constructed wetland post-treatment show that the regression equation relating to effluent BOD5,cubage load (NA),and temperature (t) is BOD5=1 190NA-0.32t+12.2. Based on the two orthogonal regression equations,combined of green building municipal gray reclaimed water quantity requirements in different seasons,a technology investment on economic optimization model of combinational technique was established. The results offer technological support for reclaimed water treatment,which regards superior drainage as the source and is purified by combinational technique of coagulation sedimentation and constructed wetland. According to the model,the reasonable scale of reclaimed water treatment systems can be determined,the treatment efficacy can be well predicted,and both the design and operating can be effectively guided.

Fire risk of green building technical components

The concept of the green building as sustainable construction has continuously been studied,developed and distributed.Technologies to realize the green building to use less energy,while protecting the environment and improving the quality of residences have increasingly been used in not only new buildings in the design phase,but also in existing ones to reduce the energy and environment loads.Therefore,the number of green buildings is increasing.However,there are some cases that green building technologies for low energy use,low carbon emissions and pleasant indoor environment violate fire safety standards;so it is imminent to address the issue.Furthermore,unlike continuous studies on development and distribution of green buildings,there are few studies on the issue because of the lack of fire safety awareness of green buildings.Therefore,this study intends to raise the awareness of fire safety awareness of green buildings through theoretical consideration and analysis of cases about green building technologies.

THE ADOPTION OF AN INNOVATION:BARRIERS TO USE OF GREEN ROOFS EXPERIENCED BY MIDWEST ARCHITECTS AND BUILDING OWNERS

While green roof technologies are increasingly employed in Northern European countries,adoption is progressing at amuch slower rate in the US.This manuscript discusses results of a survey that quantified knowledge,barriers,and perceivedcosts and benefits to use of green roof technology among a sample of architects and building owners in the Midwest.The survey also examined conditions that may encourage use of this technology among the respondents.Resultsshow that many respondents do not fully recognize the economic or performance advantages offered by green roof technologies.The payback period for economic advantage is longer than owners are willing to consider.Both owners andarchitects possess a wide range of misconceptions about the performance advantages of green roofs.While green roof technologyoffers clear environmental advantages such as reduced stormwater runoff,increased habitat,and cooler temperaturesthat mitigate heat island effects,many building owner respondents either do not know about or value these advantages.This research quantified potential adopters’perceptions of an innovative technology and the survey results areinterpreted and discussed within the conceptual framework of innovation diffusion literature.Strategies to hasten theadoption of green roof technology are suggested.

IDENTIFICATION AND EVALUATION OF GREEN BUILDING ASSESSMENT INDICATORS FOR MYANMAR

To accommodate its increasing population,the Myanmar government has planned to implement smart city projects in Yangon and Mandalay by 2021 and to build 1 million homes by 2030.However,such projected growth does not coincide with Myanmar’s current level of preparedness for sustainable development.Myanmar presently has no standards and specifications for green buildings;it solely relies on the adoption of those from overseas,which may not always be compatible with the unique context of Myanmar.Hence,this study was aimed to identify appropriate green building assessment indicators for Myanmar as an important first step for future rating system development.Nine categories and forty-eight criteria were initially identified by reviewing the widely adopted seven rating systems and investigating existing certified green buildings.The Fuzzy Analytic Hierarchy Process(Fuzzy AHP)was used to determine and rank the importance levels of the identified assessment indicators.Results showed that“energy efficiency”and“water efficiency”are the most crucial categories with weights of 17.48%and 13.95%,respectively.Compared to other rating system standards,“waste and pollution”was distinctively found as an important category for Myanmar.Energy-efficient architectural design was ranked as the highest priority among all criteria.These findings serve as a building block for the future development of a Myanmar green building rating system by revealing assess-ment categories and criteria that are most relevant to Myanmar’s built environment.

SHEARING LAYERS CONCEPT AND LEED GREEN BUILDINGS IN BOTH RATING SCHEMES AND CERTIFIED PROJECTS

The Leadership in Energy and Environmental Design(LEED)for New Construction and Major Renovations v3(NC)and LEED for Existing Buildings:Operations and Maintenance v3(EB)schemes were studied to examine the application of the shearing layer concept to green buildings.The manners in which(i)rating systems in their current configurations and(ii)certified projects in their practical applications treated the long life-expectances in buildings and short life-expectancies in systems were questioned.To maximally reduce nondemonic intrusion,we studied only those states in the United States in which statistically viable numbers of projects had been completed in 2016.A two-way mixed analysis of variance(ANOVA)model was used to evaluate the interaction between two types of buildings(i.e.,NC vs EB)and two sets of sub-layers(i.e.,Site,Structure,and Skin from the Building layer and Services,Space Plane,and Stuff from the Service layer).The discrepancy in the case of a new building and the similarity in the case of a renovated building between rating schemes and certified projects were revealed:(i)the NC rating scheme prefers to emphasize the Service layer(SL),whereas newly constructed projects prefer to emphasize the Building layer(BL)due to the high performance of the Site and Structure sub-layers;(ii)the EB rating scheme prefers to emphasize the Service layer,as do renovated building projects,due to the high performance of the Stuff sub-layer.

Radial Tire Construction Design Method Based on Finite Element Simulation

The simulation of 295/80R22. 5 tire building process from tire building to curing was developed using ABAQUS software,which covered four stages: gluing of components on main drum,gluing of components on auxiliary drum,building process of green tire and shaping process of green tire. Results showed that material distribution of the simulated structure had good consistence with the real tire structure. Therefore,the tire building process simulation can be used to judge the rationality of tire construction design and to determine the shapes of different tire components. In order to optimize the construction design,a reverse simulation method was proposed to design the semi-product components such as apex,tread,and shoulder pad. The semi-product components determined by utilizing the reverse simulation method were assembled again into a tire. Results show that the simulated material distribution is consistent with the material distribution of design tire,which proves effectiveness and reliability of the reverse simulation method.

Superior drainage treated by combinational technique of biologic contact oxidation and constructed wetland

The superior drainage was pre-treated by biologic contact oxidation on BOD5 load of 0.72 kg/(m3·d),and then post-treated by constructed wetland. The results about the effect on the constructed wetland post-treatment show that the total nitrogen (TN) is the restrictive index of the combinational technique treatment effect. To meet the reclaimed water quality standard and reuse for waterscape,the peak hydraulic load of constructed wetland is 0.50 m/d in summer (30-36 ℃) and 0.33 m/d in winter (8-12℃),and the load ratio of the peak hydraulic under the two temperature conditions is 3-2. The results are combined of reclaimed water quantity requirements in different seasons of green building. Reasonable scale of the reclaimed water treatment systems can be determined. The treatment efficacy can be well predicted,and both the design and operations can be effectively guided,by which the reclaimed water treatment systems regard superior drainage as the source and are purified by combinational technique of contact oxidation and artificial wetland.

GREEN LUXURY:A CASE STUDY OF TWO GREEN HOTELS

The hotel industry is beginning to implement green design and construction practices,saving energy,water,and resources and thus helping to preserve the environment.In addition,green building practices also can provide healthy and comfortable indoor environments to hotel occupants including guests and employees.However,there is the potential for conflict between green building practices and hotel guests’satisfaction and comfort,as the conservation of resources could detract from the quality of a guest’s visitor experience.This study adopted a case study approach to identify and analyze green design and construction practices that create a green and luxurious environment without damaging the hotels’financial position.An in-depth literature review was conducted to identify green design and construction practices,design features of premium hotels,and major design conflicts between the twin goals of green building and a luxurious hotel environment.Two LEED platinum hotels(the Proximity Hotel and the Bardessono Hotel,both in the United States)were selected and data collected on their green design and construction practices,luxurious design features,and operation and maintenance practices from multiple sources,including the owner,designer,contractor,engineer,and LEED consultant.From the perspective of the entire lifecycle of the building,this data was analyzed to identify green design and construction practices that not only provide a green,luxurious environment but also enhance the hotels’financial strength.
