The objective is to instruct future interventions for improvement in the living condition where it is particularly important for the success of the activities predicted there. Surveys on thermal comfort along with goers of the squares were held on three consecutive days in April 2013 and February 2014 with microclimate monitoring of the places adopting the predictive PET （physiological equivalent temperature） index calculated based on the bioclimatic model Rayman. The obtained data set generated valuable information about the pattern of thermal comfort allowing understanding the analytical correlations between PET index, climate variables and the perception of comfort. The article seeks to contribute towards the recognition of bioclimatic specificities in the project process aimed to the improvement of the environmental and social performance of public squares and aspects that are relevant to the urban planners.展开更多

The lack of statutory design guidelines raises concerns on how such gardens are created and whether they meet the intended design purpose. This issue is particularly important for hospitals because a neutral or even a negative effect on users can be generated. A systematic analysis of the literature in two databases （Scopus and Web of Science） was undertaken. Results showed that pre- and post-occupancy research findings on hospital healing garden design are sparse and design recommendations vary among users. Despite the tack of research on the design of healing gardens, the review showed that while post-occupancy research findings evaluate the effectiveness of design recommendations, pre-occupancy research findings, combined with site analysis, constitute a traditional approach followed in landscape architecture practice and determine the site and user features that must be addressed for each hospital. Pre- and post-research findings must be considered in the design process to create a “successful” healing garden. A summary of EBD recommendations for different users is presented, and the need to enrich the existing amount of EBD recommenda-tions is highlighted.展开更多

Underground street is a kind of underground space types, and it is also an important urban recreational resources and tourism resources. The evaluation of underground street users, especially the residents and tourists, has important reference value for the recreational resources’ redevelopment of underground street. Firstly, this paper reviews the relevant research literature on underground street and Post-Occupancy Evaluation theory, then chooses Diyi Underground Street, Chengdu, China, as the research object, and conducts a questionnaire survey and in-depth interviews on residents’ shopping intention from five dimensions of underground street environment, decoration, commercial form, public facilities and other aspects. Finally, the survey data are analyzed quantitatively. The results show that some influence factors such as air quality, daylighting, decoration style etc. greatly affect the willingness of residents to enter the street. Therefore, residents’ recreational experience should be emphasized during the underground street re-planning according to the above factors.展开更多

This paper aims to report the results of a post-occupancy evaluation (POE) conducted on four Swiss green buildings certified with the Minergie label to analyse their ability in providing comfort to their occupants.The POE protocol included winter and summer environmental monitoring campaigns (long-term and instantaneous measurements) as well as extensive and point-in-time comfort surveys. From the study it was found that,although the observed environmental factors were most of the time complying with the norm prescriptions,the indoor conditions were never attaining the commonly used 80 % satisfaction threshold by the users.Temperature and air quality appeared,in particular,as the most critical factors,with satisfaction rates never greater than 50 % in three out of the four case studies. Design factors related to the personal control on the indoor environment as well as personal factors like gender,climate of origin and duration of residence in the country were also found to have an impact in the comfort rating. Professionals involved in the design and management of these buildings all agreed that feedback of this kind from building in use could help inform the design and operational process and move towards more effective green building certification systems and regulations.展开更多

According to the construction demand of the park city, a Tianfu greenway system with the theme of “one axis, two mountains, three rings and seven belts” will be formed throughout Chengdu. Jinjiang 198 Greenway is the first large-scale greenway in the main urban area of Chengdu. In view of the use of Jinjiang 198 Greenway in Chengdu, its use characteristics and user satisfaction degree are studied. The general situation of people's use of greenway is obtained from the characteristics of users themselves and its use conditions. According to the statistics of user satisfaction degree through field survey and questionnaire survey, it is known that the overall satisfaction degree of users on the greenway is good. Through factor analysis, the main factors affecting user satisfaction degree are obtained, which are in turn supporting facilities, service facilities, activity sites,green environment and accessibility. Finally, based on the above analysis and summary, suggestions and opinions are put forward for the future construction and development of Tianfu greenway system.展开更多

The purpose of this paper is to explore a space-use analytical tool--POE （post-occupation evaluation）--regarding a neighborhood accessibility condition. Based on a site-specific approach, the main research question is focused on how far neighborhood walking paths are compatible with different user needs, guaranteeing their safety and autonomy, as well as easiness of perception and use, thus providing access to local services and resources they need for participation in the day-to-day activities of community life. This paper is organized in three parts： The first one introduces the main concepts and explains how to ensure it in a practical application in urban design; The second part presents the practical approach, referring to the used methodology, the specific case-study and reached results; The third one establishes correlations between the two approaches and discusses the main findings.展开更多
