Reflection on Full Life Cycle Green Architectural Design of Passive Priority——Taking the Award Design of China Merchants Property 2013 Green Architectural Design Competition as an Example

In the China merchants property 2013 green architectural design competition,feature of this awardwinning program is the design method based on the principles of passive priority and comprehensive utilization of full life cycle. The passive priority can be achieved by building form derived from the simulation and analysis of wind environment,improvement of the building envelope insulation and the dehumidification of fresh air,the use of solar energy. The full life cycle utilization can be accomplished by the combination of exhibition and residents' leisure activities, and the integration with local cultural tradition, thereby improving energy efficiency and the utilization of the building.

Environmental behavior, human health effect, and pollution control of heavy metal(loid)s toward full life cycle processes

Heavy metal(loid)s(HMs)have caused serious environmental pollution and health risks.Although the past few years have witnessed the achievements of studies on environmental behavior of HMs,the related toxicity mechanisms,and pollution control,their relationship remains a mystery.Researchers generally focused on one topic independently without comprehensive considerations due to the knowledge gap between environmental science and human health.Indeed,the full life cycle control of HMs is crucial and should be reconsidered with the combination of the occurrence,transport,and fate of HMs in the environment.Therefore,we started by reviewing the environmental behaviors of HMs which are affected by a variety of natural factors as well as their physicochemical properties.Furthermore,the related toxicity mechanisms were discussed according to exposure route,toxicity mechanism,and adverse consequences.In addition,the current state-of-the-art of available technologies for pollution control of HMs wastewater and solid wastes were summarized.Finally,based on the research trend,we proposed that advanced in-operando characterizations will help us better understand the fundamental reaction mechanisms,and big data analysis approaches will aid in establishing the prediction model for risk management.

Optimal configuration of 5G base station energy storage considering sleep mechanism

The high-energy consumption and high construction density of 5G base stations have greatly increased the demand for backup energy storage batteries.To maximize overall benefits for the investors and operators of base station energy storage,we proposed a bi-level optimization model for the operation of the energy storage,and the planning of 5G base stations considering the sleep mechanism.A multi-base station cooperative system composed of 5G acer stations was considered as the research object,and the outer goal was to maximize the net profit over the complete life cycle of the energy storage.Furthermore,the power and capacity of the energy storage configuration were optimized.The inner goal included the sleep mechanism of the base station,and the optimization of the energy storage charging and discharging strategy,for minimizing the daily electricity expenditure of the 5G base station system.Additionally,genetic algorithm and mixed integer programming were used to solve the bi-level optimization model,analyze the numerical example test comparison of the three types of batteries and the net income of the configuration,and finally verify the validity of the model.Furthermore,the sleep mechanism,the charging and discharging strategy for energy consumption,and the economic benefits for the operators were investigated to provide reference for the 5G base station energy storage configuration.

Study on time-varying seismic vulnerability and analysis of ECC-RC composite piers using high strength reinforcement bars in offshore environment

As the main seismic component of a bridge,seismic damage to the bridge pier has a greater effect on its subsequent service.In the offshore chloride environment,the issues(e.g.,reinforcement bar corrosion and attenuation of concrete strength)of piers caused by chloride ion seriously curtail the normal service life and deteriorate the anti-seismic property of bridge structures.The engineered cementitious composite(ECC)-reinforced concrete(RC)composite pier with high strength reinforcement bars(HSRB)is expected to solve the above problems.This study aims to clarify the time-varying seismic vulnerability(SV)of the HSRBECC-RC composite pier during its full life cycle(FLC).Based on OpenSees,the refined finite element analysis models of RC pier,ECC-RC composite pier,and HSRBECC-RC composite pier have been established.Moreover,using the nonlinear time-path dynamic analysis method,the influence of chloride ion erosion on the time-dependent seismic vulnerability(SV)of these different piers in different service life and different peak ground acceleration(PGA)were analyzed from a dynamic point of view.The research shows that the exceeding probability(EP)of the same damage level increases with the enhancement of service time and PGA and with the increase of destruction,the exceeding probability(EP)of slight damage(DL-1),moderate damage(DL-2),serious damage(DL-3),and complete collapse(DL-4)decreases in turn;the corrosion degree of chloride ion to piers is small during the early service period,the time-varying vulnerability curve of the bridge piers is almost the same as that of a new bridge,and during later service,as the extent of chloride ion corrosion deepens,exceeding probability(EP)under severe damage(DL-3)and complete collapse(DL-4)is increased,and the seismic performance is significantly enhanced.

The paper builds up a cost-benefit measuring model of green products in manufacturing industry throughout its full life cycle, which can quantify green products＇ cost and benefit completely and correctly under the circumstance of satisfying enterprise, customer, environment and society. It also puts forth an operable method to estimate social benefit by opportunity cost and establishes a profit maximization-programming model. The model can be applied to justify whether some kinds of green products should be developed and produced.

An accurate and objective assessment of the health status of EMU trains is of great importance.In order to make sure the trains are functional,reliable,and endurable in their full life cycle(FLC),health assessment method for EMU trains after Level 3-5 maintenance and repair is studied.First,the element-selection principles and the assessment rules are defined;second,to present the complex topological relationship between the elements in assessment,a functional logical structure construction method is proposed;third,a health value calculation model is defined based on the element’s characteristics and their logical structures.The health variables of each element is calculated and fitted following the steps in the corresponding weight calculation methods.The assessment method is proved to be applicable and effective.

Spatial Identities of Public Health Service Facilities in Metropolitan Suburban Communities: A Case Study of Shanghai Jinshan District

Both "Healthy China" and "Healthy Shanghai" programs require construction and development of community public health services. Taking Jinshan District in Shanghai as a case study, this paper evaluates the status quo of community health services from the "demand-supply" perspective, and finds a remarkable difference in the needs among different age groups, a big gap between urban and rural areas in the coverage degree of facilities, and different challenges for public service at the "prevention – treatment – health care" stages. It further puts forward several planning strategies involving(1) specific service supply based on different age groups,(2) "15-minute health service cycles" in both urban and rural communities,(3) adjustment of facilities to local conditions, and(4) promoting the quality of health services. Furthermore, it discusses in-depth issues underlying planning policies, such as the innovation of service content, the integration of different plans, and the cultivation of health service needs.
