Fieldwork Test Research of the Impact on Building Physical Environment on Six Types of Atrium Space in Cold Climates

Since the research on verification to passive design strategies in sustainable building is at the initial stage,and its test method and verification conclusion are not scientific enough to validate,this paper proposes the necessity of building physical environmental monitoring to quantitative optimization of passive strategies efficiency from the perspective of architecture design and building environment. Adopting comparative research method,this research chooses six types of atrium space in cold climate in China as a prototype,focusing on building physical environmental performance difference in and between atrium and building main space. Spatial parameters of the atrium space will be divided into four factors: spatial geometry,interfacial properties,internal and external related categories. With subdividing these four factors into sub-factors,this paper makes crosscomparison among the sub-factors to clarify passive strategies effectiveness in atrium. Data comparison analysis shows that Winter atrium passive strategy in cold regions from traditional view is not obvious in practical application,and test data need to be stratified refined in atrium design in case of optimizing passive strategy from building prototype perspective.

A Hygienic Survey of the Environment of Underground Space and Buildings

Full utilization of underground space and buildings could have positive economic and social effects. However, the microclimate and air quality must be well controlled so that they are not harmful to human health. This survey indicated that relative humidity is a common hygienic problem in underground space and buildings. Attention should be paid to humidity control and to the strengthening of routine ventilation at the construction stage. Carbon dioxide can be used as a hygiene index of air pollution; the sanitary standard for it in the air of underground buildings is 10%. The hygienic survey shows that the concentration of carbon dioxide is usually below this standard in the environments of underground space and buildings. (c)1989 Academic Press,Inc.

Development an Adaptive Environmental Assessment Method for Buildings

The idea behind this work is developing an adaptive method for the environmental assessment of buildings, to configure different versions according to the variables affecting them (spatial, temporal and associated with building characteristics) to suit different evaluated projects. This method may be applied using an electronic tool, which is in a development stage. Amending different assessment versions of the adaptive method is done by including the variables effect, according to set of steps, such as modifying the formulation of the assessment items, adjusting their estimation weights, and amending their achievement evaluation levels and their returned scores. When using the adaptive method, the assessment result of a building using a certain version differs from the results using other versions, even in the same country, so configuring an appropriate version due to the variables affecting the assessment helps getting more accurate results than the ones currently provided. The main goal of that research is to introduce the adaptive method that is proposed to ensure a fairer assessment results from the perspective of Green Architecture, and allow a more credible and accuracy of results comparison according to the environmental performance of buildings. The researcher analyzed the different main features she used in developing the adaptive method, the Comparative aspects between it and the current assessment methods, and the expected reached advantages from its usage. The paper arrived to the importance of adapting the environmental assessment of buildings according to the different affecting variables, and recommended developing the adaptive method and its tool to the stage of application to benefit its advantages.

Assessment of Minimizing the Environmental Functions Conflict in Buildings

Some building components are responsible for achieving more than one environmental function, these functions are usually of different requirements that can never be done by the same actions, and they are usually connected to changeable internal and external environment characteristics that vary among them. Minimizing the conflict of achieving the different environmental functions is an important challenge for all designers. Achieving a continuous thermal and optical comfort in an internal building space using the same window is an example of this challenge, as they have different requirements that may be sometimes contrary. It should be notable that there are a lot of recent technologies that may be used to find solutions for such a conflict. The Environmental Assessment Methods of Buildings appeared to set the principles of the optimum relation between buildings and their environment, they also could be used to encourage designers to reach the best environmental relations, and award them by main or additional assessment points. The research paper proposes to use the Environmental Assessment Methods of Buildings to assess the building ability of minimizing its environmental functions achievement conflict. This proposal depends on determining the inconsistency assessment items that depend on common building components to be achieved, and then determining the time periods that these items are achieved together within, to indicate the time periods without conflicting. Thus, the paper aims to raise the building environmental value in the assessment when the designer succeeds to minimize the expected conflict of the building environmental functions.

Benchmarking of energy efficiency standards for residential buildings in China

In order to benchmark the energy efficiency standards for residential buildings in China,the Hong Kong building environment assessment method（HK-BEAM）is chosen as the compliance criteria for assessment.The annual energy consumption and the overall thermal transfer value（OTTV）of a baseline residential building prescribed in the Chinese codes and the HK-BEAM are evaluated and compared by the energy budget approach.The results show that in the Chinese codes,the OTTV of the residential building is lower,but the annual energy consumption and the cooling load are higher than those in the HK-BEAM.The annual energy use difference amounts to 13.4%.All the compliance criteria except the ventilation rate and the equipment power in the Chinese codes are set higher than those in the HK-BEAM.However,the compliance criteria of the ventilation rate and the equipment power,especially the ventilation rate,result in much energy consumption,which ultimately induces a high energy budget for residential buildings.

多学科和多行业协同破解建筑室内空气质量难题

Healthy building is a new trend after green buildings in the world."WELL"was launched as the first guideline for healthy buildings in 2014 in USA.In 2017,China Healthy Building Assessment Standard was launched.Good indoor air quality is an important part for healthy buildings.The score of indoor air quality accounts for nearly 25 in the total score(100)in Healthy Building Assessment Standard(T/ASC 02-2016).The indoor air quality items in the standards are mainly based upon China Indoor Air Quality Standard(GB/T 18883-2001).However,the target indoor air pollutants in the both standards(T/ASC 02-2016 and GB/T 18883-2001)are not determined based upon the indoor air quality investigations in China.In order to revise the China Indoor Air Quality Standard(GB/T 18883-2001)and improve or develop the relevant indoor air quality control techniques,it’s necessary to know the important and unsolved problems in indoor air quality control in China.From them,the important scientific problems and key technical problems in China can be identified,and the gaps between the control demands and the levels of the related industries in China can be recognized.Then,various control approaches and strategies can be developed effectively.For this purpose,we present a series of important and unsolved problems in indoor air quality control in China:Identify the target indoor air pollutants and the corresponding thresholds based upon China’s indoor air quality situations,develop energy efficient engineering approaches to simultaneously control indoor air climate and quality,and develop the approach of scientific evaluation for indoor air quality control effect.The important scientific and key technical problems behind them are:The method of determining the target indoor air pollutants,the method of determining the thresholds of the target indoor air pollutants,the principle and method to overall control of indoor air climate and quality,the method of scientific evaluation for indoor air quality control effect not only based upon the concentrations of the target indoor air pollutants but also based upon the human health response.We are carrying out a national research project whose title is"study on fundamental problems and key technical approaches in indoor air quality control".Based upon its research advance,we put forward a framework and understanding of solving the aforementioned problems:(1)Determining the target indoor air pollutants based upon the burden of diseases of indoor air pollutants in China.In the study,the burden of diseases of all target indoor air pollutants is obtained so that the overall burden of diseases of indoor air pollution can be roughly estimated.It’s a quantitative index to show the importance of indoor air quality problems in China.(2)Determining the corresponding thresholds of the indoor air pollutants based upon the control feasibility and the health benefit.The healthy benefit can be evaluated by the reduction of burden of diseases of the target indoor air pollutants which can also be equivalent as the reduction of economic loss.(3)Developing inverse problem and variation method to identify the optimal control systems and operative strategies.It’s an original novel approach for indoor air quality control.(4)Developing some partial space and/or partial time control approaches for indoor air quality.(5)Developing novel evaluation method for control effect by using biomarker-based techniques.(6)Narrowing or even removing the gaps between the indoor air quality control related industries.The indoor air quality control standards in those industries shouldn’t conflict each other.(7)Applying various newly-developed sensors and big data techniques to understand the links between the indoor air quality and human health response.New on-line monitoring sensors with acceptable precision,together with some new big-data analysis methods are strongly needed.To tackling the above problems which are related to many disciplines,collaboration among multi-disciplinary research and industries is very important.

Livability assessment of 101,630 communities in China's major cities: A remote sensing perspective

Some of China's major cities have entered the middle and late stages of urbanization, and the development focus of these cities has gradually shifted from outward expansion to inward renewal. The community, as the basic unit of a city, is undoubtedly the main object of urban renewal. In order to efficiently and effectively address the problems in current community construction, it is necessary to conduct a large-scale in-depth assessment of the community livability, which can directly imply the satisfaction of residents with their quality of life. This study achieved the first comprehensive livability assessment at the individual community scale for 42 major cities of China from the perspective of remotely sensed and crowd-sourced geographic information. Specifically, we produced abundant fine-grained datasets for 42 cities, including high-resolution land cover maps interpreted from Ziyuan-3 satellites(ZY-3, 2.1 m), building height, point-of-interest, and boundaries of 101,630 communities.As designed in our proposed framework, the community livability was evaluated by 5 level-1 indicators, 27 level-2 indicators and an integrated community livability index(CLI). A number of interesting findings were obtained from this assessment:(1)According to the expert questionnaires, living comfort was considered as the most important livability factor for residents with the highest weight, while the building environment was rated the least. The negative factors(e.g., the factories around the community) impacted more on livability than the positive ones.(2) Most communities in major Chinese cities were characterized by dense buildings and sparse green spaces.(3) In these cities, community security construction was severely insufficient,particularly in less developed regions.(4) Imbalanced community livability development was prevalent across cities, and simultaneously, the CLI distribution within cities also exhibited significant spatial aggregation and heterogeneity. This research is expected to reveal the status quo of community livability in China, and thus allow for targeted policy formulation.
