Architecture and sustainability: the role of environmental rating systems - case study in Brazil
Authors: Santos Salgado Monica 
Published: August 2019

Abstract
The predatory impact of civil construction industry does not seem to occur consciously. It is a process that results from the rapid growth of populations and the necessary response - with the construction of new buildings, the expansion of existing cities and the creation of new ones. In this sense, it seems pertinent to discuss the practices adopted during design and construction process in order to preserve the environment. Throughout the 1990s different environmental rating systems had emerged. UK BREEAM certification has been followed by North American LEED, French HQE and others. However, the careful analysis of the most popular methods indicates that the environmental and economic aspects of sustainability have been valued, leaving social issues in the background. On 2000, Japanese architects have drawn up a chart for environmental architecture which relates environmental, economic and social aspects in an inseparable way. The document reveals aspects that have never been considered by traditional environmental rating systems. In this sense, the purpose of this research is to present a critical analysis of the environmental rating systems adopted in Brazil confronting requirements defined by LEED and AQUA-HQE methods to the sustainable principles proposed by Japanese Architectural Charter for a Global Environment. Results indicate that, in decoupling environmental issues from other aspects of sustainable development, the environmental rating systems have become obsolete and inefficient.

Abstract
Asian office buildings receive plenty of heat and daylight because of their glazing facades. They also allow the occupants to view outside. These effects depend on the seat position in different distance from the window. A study of building performance regarding those difference effects is required to clarify the occupants’ comfort under contextual conditions. Therefore, this study aims to compare the impact of glazing facades on occupants’ comfort between the occupants in the perimeter zone and interior zone by analyzing the building performance in terms of thermal comfort and visual comfort. Measuring devices were installed to investigate temperature, humidity, and daylight in three office buildings in Thailand and three in Singapore. Simultaneously, occupants’ satisfaction were investigated using questionnaires during working hours. In total, 1,356 samples were surveyed. The questions were fixed for both thermal environment and visual environment in terms of sensation and satisfaction. Furthermore, the opening view and internal blind occlusion rate were noted by visual inspection. The results showed that the thermal environment and visual environment in the perimeter zone were affected by the outdoor environment more than the interior zone. However, most of the occupants were satisfied because they be able to adapt to a wide range of indoor environment conditions. The occupants in the perimeter zone were more satisfied in terms of temperature and view. On the contrary, occupants in the interior zone were more satisfied by the lighting environment. The dissatisfaction survey revealed that the thermal environment has the most influence on occupants’ comfort. However, daylight accessing was revealed to has the highest impact on occupants’ comfort in terms of building-facade effect. The results show that occupants’ comfort levels differed depending on the seat position in the current situation for Asian office buildings. The optimisation of building-facade performance considering its influence on occupants’ comfort is necessary.
Evaluation of lifestyle factors including people’s values affecting electricity consumption in homes
Authors: Otsuka A , Narumi D 
Published: August 2019

Abstract
A critical view holds that people’s values are integral to lifestyle choices. This study investigated the effects of these values, energy-attitudes, and cognition on home electricity consumption through a case study on an all-electric apartment with HEMS in Yokohama. The conceptual framework assumed that “socially oriented values are related to factors that form energy-attitudes leading to a higher level of behavioral intentions and actual behaviors (and vice versa)” according to Schwartz’s basic human value theory and several other sociopsychological models. Results suggest the importance of fostering self-transcendent values in linking people’s behavioral intentions to actual actions. This study was one of the first to include people’s values when considering energy-saving lifestyles in Japan. The fact that people’s values have a certain level of influence on energy consumption has implications on future policy. This sheds light on the need for further research in this area, and thus in realizing energy-saving lifestyles.
A field experiment on green walls taking into consideration wind flow in the hot-humid climate of Indonesia

Published: August 2019

Abstract
This paper presents the results of a preliminary experiment using test cells constructed in Bandung, Indonesia. We particularly analysed the thermal effects by comparing green walls with wooden blinds in contrast with those of no covering materials to determine the factors affecting the improvements of indoor thermal conditions in hot-humid climates. The results showed that, unexpectedly, indoor thermal conditions were not improved when green walls/blinds were installed, at least at the center of the units. Nevertheless, air temperatures behind the green walls were found to be lower than those of the other conditions. Moreover, the factors affecting the Standard Effective Temperature (SET*) were analysed in detail by dividing SET* into four thermal factors in terms of temperature, including air temperature, radiation, humidity and wind speed. The further analysis showed that the increases in SET* in the units with green walls were mainly attributed to the reduction of wind velocities (36–45%). It can be concluded that the airflow blockage effect by the green walls was larger than its transpiration cooling effect at the center of the units.

Published: August 2019

Abstract
In rapidly growing countries, such as in Indonesia, dramatic increase in new urban houses constructed of modern building materials without sufficient material standards or minimum ventilation rates may cause health problems related with indoor air quality (IAQ). This study investigates the current IAQ and health condition in Kampongs and high-rise apartments in Jakarta and Surabaya, Indonesia. Concentrations of formaldehyde and TVOC were measured, whereas a questionnaire was conducted to collect the data of building attributes, cleaning behaviour, ventilation duration, personal information and health. 707 respondents were interviewed, and 163 rooms were measured from September 2017 to October 2018 in Surabaya and Jakarta. The results showed that overall, the newly constructed apartments recorded higher formaldehyde compared to Kampongs—more than 60% in apartments exceeded the WHO standard of 0.08 ppm. On the other hand, there was little difference in TVOC between Kampongs and apartments and the maximum values reached from 8, 000 up to 21, 800 µg/m

. In general, the multiple chemical sensitivity (MCS) of occupants in apartments was twice as high as that in Kampongs. Further, the occupants with higher IAQ measurement results corresponded to the higher MCS risk. The primary results showed a high possibility of IAQ-related health problems in both Kampongs and newly constructed apartments in Indonesia although the main causes were probably different between them.

Abstract
Over the last several decades developing countries, especially in Asia, have undergone large scale rapid urbanization, impacting their developmental patterns. Compounded with increased economic prosperity and social mobility attracting individuals and companies, to urban centres, has led to severe administrative challenges that can negatively affect the citizens, nation, and environment. In efforts to mitigate those adverse side effects cities have instituted, or citizens naturally adopted, a variety of strategies to address those issues. These strategies result in the typologies of rapid urbanization that are most prevalent in developing Asian cities. By focusing on Asian and Chinese cities, using shanghai as a test case, this research proposes several major typological categories associated with rapidly urbanizing areas. Shanghai’s rapid urbanization has been shaped by seven main typologies of urban growth and expansion, since the implementation of China’s economic growth policies and its resurgence as an influential global city. Spatial typological patterns of urban growth in Shanghai are analyzed to explain how the economic prosperity and social mobility have been managed. Typological adaptations learned from the historical urban expansion provide the subsequent strategies for future sustainable development in a rapidly urbanizing area.

Abstract
Dynamically tunable cut wire and split ring resonators (SRRs) based on monolayer graphene metamaterials are presented in terahertz regime. As the Fermi level of the graphene pattern increasing, the resonance frequency presents blue shift and higher intensity. Two resonant peaks that can be modulated dynamically in the range of 2.4-3.4THz and 4.1-5.8THz appear. The monolayer graphene metamaterials realize dynamically broadband terahertz modulation with a minimum modulation depth 63.9% at 2.74THz, and the highest modulation depth 93.3% at 3.4THz.

Abstract
Based on the combination of theoretical analysis and site test, regard-ing to sedimentation problem of super-large tonnage static load test, this paper studies pile sedimentation, lateral friction resistance of pile, pile tip resistance, rel-ative displacement of pile and other physical and mechanical changes characteris-tics. The results show that the Q-s curve of the pile shows a slow change charac-teristic, and the rebound rate of the test pile is 29.26%. The sedimentation curve of the pile gradually changes from the elastic phase to the plastic stage with the increase of the load. With the increase of the applied load at the tip of the pile, the variation curve’ slope of the axial force of the pile shaft gradually decreases, and the lateral friction resistance of the shallow soil show trends of gradually de-crease compared with deep soil, while the relative displacement of pile top and bottom is gradually increasing. The resistance and displacement of pile tip also show a significant proportional relationship. The lateral friction resistance of silty clay has a greater effect on the pile shaft. With the further increase of the depth, the axial force of the pile shaft is obviously decreasing, the decay speed is faster, the pile tip resistance is gradually increased, showing a distinct feature of the fric-tion pile. In this paper, the calculation and analysis procedure of large diameter bored pile is proposed. The nonlinear sedimentation problem of the pile and the surrounding medium is simulated by nonlinear treatment module of the finite element method in the software. The prediction results are basically the same as those of the on-site monitoring results, and the overall prediction accuracy reach-es 88.79%.

Published: August 2019

Abstract
With the development of economy and the increasing growth rate of population, people’s increasing demand for water resources and the unreasonable exploitation and usage of water resource, water scarcity exists in many countries and regions. Accordingly, the research on how to solve the water scarcity is of great value. Firstly, considering the dynamic influence of time on water resource supply and demand and the two factors including the degree of water resource exploitation and per capita availability of water, the water resource supply and demand model is built to measure the capacity of the region to offer clean water. This paper selected the lower per capita water use in north China as the object. This water scarcity in this area is severe due to its large population, less natural water distribution, large proportion of agriculture and low usage of industrial and agricultural water. Secondly, building up the Logistic model and grey prediction model to predict the following 15 years’ population situation and the total water resource supply in north China. Use the intervention plan which combined waste water recycling and water transfer project to intervene water resources. Lastly, combined with intervention plan and introducing validity coefficients to improve the supply and demand model of water resources, it can be estimated that by the year of 2020, water scarcity in the certain area will be alleviated.

Abstract
The definition of mine water related concepts involves 6 relevant standards in 6 sectors, 2 mandatory standards, 3 recommended standards, and 1 industry standard. Multi-sectors are inconsistent in the concept and definition of statistical caliber, and the concept of policy is confusing during the formulation and implementation of relevant policy documents, resulting in large errors in statistical data. This paper is based on the analysis of the concept of mine water and the integration of doubts. In conjunction with the relevant requirements of the “Guiding Opinions of the Ministry of Water Resources on the Unconventional Water Sources incorporated into the Unified Allocation of Water Resources”, Conceptual definition of regular mine water quantity, mine water availability, mine water development and utilization, and mine water development and utilization potential, unify the statistical caliber of each department and minimize the difference in statistical data. It is conducive to water resources investigation and management, which are conducive to the integration of unconventional water resources into water resources, alleviating the contradiction between water supply and demand, and improving regional water resource allocation efficiency and utilization efficiency.

Authors: Wang Di , Wang Xuemei , He Min , Zhang Jinchang 
Published: August 2019

Abstract
In order to solve the current difficulty of radiation calculation of current missile phased array radar arrays, the elemental radiation pattern of small arrays is used to calculate the unit radiation field in a similar environment in large arrays by the element active pattern equivalent method, and then the superposition theorem is used. Calculating the total radiation field of the large array avoids matrix operations in the calculation process and reduces the amount of calculation. And the linear array is extended to the missile-mounted phased array radar antenna array. The radiation pattern of a certain type of missile-loaded phased array radar antenna array considering mutual coupling is calculated. The obtained radiation pattern is in good agreement with the far field test results. The comparison with the far field experiment shows the effectiveness of the method.
