Pilot study of a concise and user-friendly management framework of green building project and an optimization tool for Assessment Standard for Green Building
Green building management is an important part of the development of sustainable and green building practices.However,the current paradigm of green building management faces three dilemmas:the application schema of Assessment Standard for Green Building(ASGB)does not match phases in building project flow and is extremely complicated.In addition,alignment between the categorization of standard terms and the process of building projects is scarce;effective tools enabling project managers to quickly assimilate the ASGB standard is absent;user acceptability is inadequate,and the studies on incremental cost rates of standard terms are few.Through literature review,industry interviews,random questionnaires,expert consultations,comparative case studies between domestic and foreign projects,and programming experiments,this study conducts qualitative and quantitative studies on the existing framework of the ASGB standard,user acceptability,and the direct incremental cost rates of high-scoring standard terms and develops a user-friendly decision-making instrument that facilitates the strategic planning of project development.This tool is designed to enable project managers to precisely set the goal for green building and guide project leaders in organizing different professionals according to spatial level for the implementation of selected green building measures.Ultimately,the development of a succinct and accessible green building operational manual and a miniprogram enhance the practical application of the ASGB standard to building projects and thereby fosters proactive engagement among decision-makers.This article does not only focus on the green sustainability of new buildings but also attaches importance to the renovation and updating of existing buildings to afford them green sustainability.Spatial hierarchy theory is introduced to the ASGB standard.Space has five levels:city,community,building,basic structures(including public energy-saving equipment and materials),and internal diversified functions,space,and household equipment.Three innovative areas are explored.First,it classifies the scoring terms of the ASGB standard according to spatial level,project type,decision-maker and spatial"hierarchy"theoretical framework and reorganizes them into a green building hierarchy framework that enables professionals in the construction industry and developers to understand and operate.Second,the study investigates the characteristics of green buildings with high public acceptance and low incremental cost rates,constructs economic and acceptance indicators,and embeds newly constructed indicators into the hierarchical framework of green buildings.Therefore,existing methods and theories of green building management in academic theory are updated.Finally,an operational manual for the ASGB standard is developed on the basis of the perspectives of construction industry professionals and developer managers.This manual enables professionals and developer managers from construction industry to quickly understand personnel and tasks required for the implementation of green building projects.This feature is the value of the research results in practical applications.By studying the acceptability and economy of green building measures,it's found that the ASGB standard terms and green building measures at the city,building,and management levels are highly recognized,have low direct incremental cost rates,and high achievable ratings.Although structure and technical innovations are the important components of the ASGB standard,have high scores,and are widely adopted in existing green building three-star projects in Guangdong,their economic viability is low and their recognition is average.The community and functional levels have the lowest scores but should be carefully considered in project decision-making.Energy-saving technologies between the"three stars"green buildings in Guangdong and BE green buildings in Europe have three differences.The"three stars"cases mainly adopt active energy-saving technology,whereas the BE cases focus on passive energy-saving design."Three-stars"cases tend to use high-tech equipment,and BE cases tend to reduce or eliminate the use of building equipment.The intelligent systems in"three-stars"case mainly focus on monitoring.By contrast,the BE cases utilize monitoring data for real-time intelligent control.To enhance the operability of green building management,establishing a comprehensive green building management tool that is in line with China's national conditions is necessary.This study combines the green building process with spatial hierarchy,classifies individual allocation and the ASGB standard terms according to spatial hierarchy,and clarifies their economic and acceptability.Moreover,the ASGB standard operational manual and corresponding green building management miniprogram are established.Practices have proven that the use of this tool by professionals can effectively enhance participation in green building decision-making,facilitate the rapid development of strategies that meet the star rating requirements of green building projects,and enhance awareness of sustainable development and green building standards.
