To remodel the vitality of public spaces in old residential communities, this paper based on the field investigation of Qingshanhu Community in Nanchang City explored the thoughts of revitalizing public spaces in old residential communities from the aspects of society and material environment, and put forward the strategies of designing vitality of public spaces in old residential communities.

High-Rise Residential Reinforced Concrete Building Optimisation

In the last few decades structure optimisation has become a main task in a civil engineering project. As a matter of fact, due to the complexity and particularity of every structure, the great amount of variables and design criteria to considerate and many other factors, a general optimisation’s method is not simple to formulate. As a result, this paper focuses on how to provide a successful optimisation method for a particular building type, high-rise reinforced concrete buildings. The optimization method is based on decomposition of the main structure into substructures: floor system, vertical load resisting system, lateral load resisting system and foundation system;then each of the subsystems using the design criteria established at the building codes is improved. Due to the effect of the superstructure optimisation on the foundation system, vertical and lateral load resisting system is the last to be considered after the improvement of floor. Finally, as a case example, using the method explained in the paper, a 30-story-high high-rise residential building complex is analysed and optimised, achieving good results in terms of structural behaviour and diminishing the overall cost of the structure.

Construction and application of an assessment index system for evalu ating the eco-community’s sustainability

An assessment index system including environment, socio-culture, economy and technology was established for evaluating environmental construction level of community （objective construction）, and questionnaire was designed according to paper review for evaluating residential satisfaction （subjective satisfaction）. The index system was divided into four layers： system （A）, subsystems （B）, categories （C）, and indicators （D）, and in total of 38 indicators was established. The Xihe community, affiliated to Nanfen district, Benxi City, Liaoning Province, China was selected as a case study. Results indicated that the community sustainability index related to objective environmental construction was 0.4355 and was classified as class Ⅲ （moderate）; the community sustainability index related to the residential satisfaction was 0.4255, belonging to class Ⅲ. In conclusion, the sustainability of Xihe community was moderate and needed to be improved. Residential satisfaction was lower than objective environmental construction. The assessment index system established in this study is able to reflect the comprehensive sustainability of community and can be used to evaluate other similar communities＇ sustainability.

Impact of window and air-conditioner operation behaviour on cooling load in high-rise residential buildings

Space cooling is an important building energy end-use that was found in recent years to be significantly impacted by occupant behaviours.However,the majority of previous studies ignored the interplay between the operation of windows and air conditioners(ACs)on cooling load,particularly in building energy modelling.In addition,studies on the analysis of cooling load characteristics regarding high-rise buildings are insufficient.The vertical effect of high-rise buildings on cooling load remains vague.This study thus aims to examine how window and AC operation behaviours impact the cooling load of high-rise buildings in an urban context demonstrated by a real-life typical 40-floor residential building in Hong Kong.This study investigates window and AC operation behaviours jointly and examines the vertical effect on cooling load by using agent-based building energy modelling(BEM)techniques and initiating stochastic and diverse behaviour modes.A carefully designed questionnaire survey was conducted to help build behaviour modes and validate energy models.Ninety building energy models were established integrating meteorological parameters generated by the computational fluid dynamics(CFD)programme for ten typical floors and nine combinations of window and AC behaviour modes.The results show that comfort-based AC modes and schedule-based window modes yielded the lowest cooling load.Considering the combined effect of AC and window uses,the maximum difference in cooling loads could be 26.8%.Behaviour modes and building height induce up to 32.4%differences in cooling loads.Besides,a deviation between the behaviour modes and height on the cooling load was found.The findings will help develop a thorough energy model inferring occupants’window and AC behaviour modes along with the building height in high-rise residential buildings.The findings indicate that the interaction impact of window and AC behaviour modes and height should be jointly considered in future high-rise building energy modelling,building energy standards,and policymaking.

Resident's Floor Level Preference in High-Rise Residential Buildings in China:A Case Study of Shijiazhuang City,Hebei Province

With the constant advance of global urbanization and aggravation of urban construction land scarcity,high-rise residential buildings have become one of the main carriers of urban residential function on account of both land saving and large housing requirement.However,relevant studies on consumers' floor selection preference in high-rise residential buildings,regarding what inherent and regular features and causes it has,are still insufficient,despite that related issues have important practical significance for real estate developers and designers' decision making in terms of dwelling size ratio,floor area,indoor layout,and so on.This study,based on systematic examination of existing domestic and international researches,seeks to make empirical tests and generalization on the above issues from the aspect of "utility function"(safety,comfortableness,accessibility and economic efficiency) of the living environment that impacted by different floor levels,and floor selection features regarding consumers' social and family structure attributes,as well as the intrinsic correlation between them.The results show the existence of floor level preference in high-rise residential buildings.Its essence is a personalized characterization of consumers' social and family structures' attributes in selecting the "utility function" of the living environment,as the preference value differs under various attributes including gender,age,income,family members and others.
