Blurb about the presentation:

Housing reconstruction is a key issue of post-earthquake recovery initiatives, especially in developing countries. From an extensive review of post-earthquake reconstruction all over the world, there are two main issues. First, developing countries were impacted by the earthquakes significantly on the housing sectors. Second, developing countries suffered great challenges in implementing permanent housing reconstruction programmes after earthquake because of the lack of systematic guidelines and effectiveness. This paper will review this field and present a set of selected examples that can offer lessons for future reference. It will develop a systematic guideline and promote it in developing countries, especially in rural China. There is also a demonstration project which has been built by this theory in poor rural areas of Southwest China which have suffered a recent earthquake. The demonstration project mainly focuses on the seismic capacity, thermal comfort, and cost of construction. It also considered the reduction of environmental and ecological damage in the entire process. The project can be used to verify the systematic guideline and also provide a reference for the local government to make rules for other reconstruction projects.

Topic: Green Space Accessibility and Physical Activities of the Elderly in High Density Cities: A Case Study of Hong Kong

Moderator: Ms. TAN Zheng (PhD Student)

Date: 16 March 2016 (Wednesday)

Time: 4:30 pm – 5:00 pm

Venue: Room 905, Yasumoto International Academic Park

Blurb about the presentation:

Hong Kong is an ageing society. According to the World Health Organization, an estimated 22% of its residents will be 60 years old or above by the year 2030. Physical activities provide an important way for older people to keep healthy. It is widely documented that the environment in which older people live plays an important role in promoting or inhibiting physical activity. In particular, green space has been recognized as an important behavior setting for physical activity.

This study first conducted a prospective cohort study of 4,000 older people in Hong Kong between 2001 and 2009. From this comprehensive prospective cohort database, we calculated the Physical Component Summary (PCS) Index, which indicates the physical status of the elderly people, and have gained insight on many ageing related physical health problems. Secondly, focusing on the road network of Hong Kong, the increasing meters radius buffer around neighborhood green spaces from 100m-5000m could be analyzed. Thirdly, according to the average walking speed of elderly people, the study conducted the accessibility analysis result of green space based on actual walking time for elderly people.

A statistically significant and positive interaction between the accessibility of green spaces, the variation in neighborhood green space and physical health status of 4,000 elderly people was observed. The results illustrate the necessity of targeted intervention strategies in aging-friendly planning via green space planning and optimized physical design of urban built environments in high density cities.

Blurb about the presentation:

Without the loss of generality, the exchange of radiant fluxes between different surfaces in outdoor spaces can be described based on enclosure theory (or net-radiation method) in order to have a general understanding of the relationship between different surfaces and consequent long-wave radiant fluxes, and, hence, the mean radiant temperature within the enclosure. An enclosure could be constructed by including the real surfaces of a building facade and the imaginary surface of a sky dome. This study attempts to identify and evaluate the empirical relation between radiant fluxes from six directions as measured by net radiometers in outdoor spaces. Linear regression is adopted to model the radiant fluxes.

Mr. Alan Lai is an MPhil. student in the School of Architecture at The Chinese University of Hong Kong. He received his B.Sc. in Physics from CUHK. He worked as a research assistant in the Environmental and Sustainable Design Unit at the School of Architecture, CUHK. His research interests include modelling of solar radiation, radiation heat transfer, computational fluid dynamics, building science and outdoor thermal comfort.

Topic: Resilience Practice for Rural Areas: A Case in Southwest China

Moderator: Ms. TAN Zheng (PhD Student)

Date: 16 March 2016 (Wednesday)

Time: 5:30 pm – 6:00 pm

Venue: Room 905, Yasumoto International Academic Park

Blurb about the presentation:

Unprecedented changes have emerged in vast rural China from the state’s establishment to its current “New Normal” situation based on various progresses and reformations of development approaches, inter alia, the urban-rural integrated development. Qiunatong Village, located at Yunnan’s border area neighbouring Tibet and Myanmar, provide a useful illustration of the specific vulnerabilities and challenges that peripheral rural areas are facing in their modernization. Resilience, as an innovative and indispensable target of the global endeavour in sustainable development, encourage interdisciplinary collaboration to focus on particular regions, nations, and groups, reducing vulnerabilities and building capacities to address livelihood improvement and human well-being. Resilient and sustainable developing assistances in Qiunatong Village is a case for understanding baseline supplement, strategy formation, and impact mitigation for peripheral rural areas in China.

Topic: A Design Concept for Low‑volume Footbridges in Low‑income Rural Areas of China

Moderator: Ms. TAN Zheng (PhD Student)

Date: 16 March 2016 (Wednesday)

Time: 6:00 pm – 6:30 pm

Venue: Room 905, Yasumoto International Academic Park

Blurb about the presentation:

In China, footbridges are important links between rural villages and the outside world. However, with limited resources, local governments often fail to construct every footbridge in need. The search for a low‑cost and easily adaptable method to provide river-crossings has a high social significance. Considering low‑volume traffic in villages, the concept of temporary bridges is presented as a relevant solution. It is an interim approach to solve the current river-crossing problems before constructing normal permanent bridges, which usually entail higher costs. This seminar introduces a concept for temporary bridges and a designed case based on this concept.
