On June 26th, the BJTU+ team held the second online course lecture. We were fortunate to invite Zhang Chunmei from Chan Cheung Mun Chung Charitable Fundto introduce us to the QSAND system.
QSAND全称为(Quantifying Sustainability in the Aftermath of Natural Disasters)，即量化自然灾害之后的可持续性，是一项自我评估工具，用于推广及告知自然灾害之后进行救济、恢复和重建的可持续方法。
The full name of QSAND is (Quantifying Sustainability in the Aftermath of Natural Disasters), that is, quantifying the sustainability after natural disasters. It is a self-assessment tool used to promote and inform sustainable methods for relief, recovery and reconstruction after natural disasters.
The purpose of QSAND is to promote and promote sustainable methods of relief, recovery and reconstruction in shelters and settlements after natural disasters, so as to ensure economic, social and health benefits for the community in the short and long term, while supporting and protecting Natural environment. The goal is to guide and inform disaster-affected communities, promote more sustainable decision-making processes to shelters and resettlement activities, and provide identification and comparison of disaster-affected communities’ relief, recovery and reconstruction options, or sustainable solutions Coordination framework.
The BRE Trust is the largest charity in the UK, dedicated to research and education in the built environment. The trust fund was established in 2002 to promote knowledge, innovation and exchange for the benefit of the public. The fund uses all the profits obtained by the Bray Group to fund new research and education programs to help achieve its goal of "building a better world together". The trust committee studies the challenges faced by the built environment and publishes the project survey results as an authoritative guide for the construction industry.
Through its activities, the Trust Fund aims to achieve:
•更高质量的建筑环境/Higher quality built environment
•提供改进功能和性价比的设施/Provide facilities with improved functions and cost-effectiveness
•更高效和可持续的建筑/More efficient and sustainable construction
The theme brought by Zhang Chunmei is "WASH (Water Supply, Environmental Sanitation and Sanitation Promotion)", focusing on a series of post-disaster humanitarian rescue needs, providing corresponding solutions, focusing on water supply, environmental sanitation and sanitation promotion. We also learned about the measures and programs adopted by the Sphere, the International Federation of Red Cross and Red Crescent (IFRC) and the Chinese Red Cross (RCSC) in the WASH project.
About how QSAND defines sustainability and its scope of application
The definition of sustainable development in modern society is to satisfy the needs and expectations of modern people without compromising the ability to meet the needs and expectations of future generations. The QSAND tool uses the three pillars of society, environment, and economy as the benchmark for defining sustainable development.
QSAND applies to the consequences of a series of fast-occurring natural disasters that require partial or full reconstruction, rather than formulating strategies to deal with long-term health, biological or climatic conditions or changes (whether caused by man-made or natural causes).
After a disaster occurs, by analyzing the geographic location of the post-disaster area, the type of resettlement site, and the disaster timeline, the QSAND system can use different tool structures to solve related problems.
Used in the emergency relief and early recovery phases of a project or plan, it is the forerunner of CAT (but can also be used independently of CAT). It is intended to serve as a quick reference guide for applying sustainability after natural disasters, and to assist in emergency relief or The early recovery phase prevents decisions that may have negative long-term effects during the recovery or reconstruction phase.
Used in the recovery and reconstruction phase, it forms the main part of the QSAND tool, and contains detailed guidelines and performance-related project features, designed to support the establishment of a sustainable built environment. As a guide for considering and applying sustainability after natural disasters in mid- and long-term reconstruction plans, by providing a coordination framework, listing and evaluating sustainable solutions during the recovery and reconstruction of disaster-affected communities, and supporting decision-making processes, Provide simple measurements (and related quantifications) of the sustainability options and methods applied, and inform the decision-making process by showing the relative benefits of different options.
The QSAND tool is divided into eight sustainability categories related to sustainable built environment reconstruction, seven of which involve problem assessment, and one category (crossover) supports the application and assessment of seven other issues.
The QSAND tool assessment system includes 22 single questions, spanning seven sustainability categories, plus an eighth category containing eight cross-cutting questions. In the CAT rating percentage scoring stage, there are four key steps to go through: select questions related to project/plan evaluation, determine the relevance of each question to the evaluated project/plan, evaluate CAT questions and related performance levels and availability Points, the final calculation of CAT scores and grades.
In this course lecture, Mr. Chunmei Zhang explained the relevant knowledge of the QSAND system in detail. In the course of more than two hours, she used her rich work experience as the theoretical cornerstone to explain the boring theoretical framework in a flexible and vivid manner, so that all members who listened to the lecture The meaning is still unfinished. Using the time at the end of the course, Mr. Chunmei patiently answered the questions raised by the members, instructed the members on how to apply the theoretical knowledge to solve practical problems, expanded the members’ thinking, and provided a theoretical basis for the subsequent design and construction work. , So that everyone has a deeper understanding and understanding of the QSAND system.
Through Mrs.Zhang’s explanation, we have a deeper understanding that the construction of buildings after the disaster should not be a simple temporary construction,
but a warm project with a complete evaluation and construction system. An architect's view of architecture is often the embodiment of his world view.
Real architecture must know how to start from the human point of view to build the vibes of life.
QSAND system has passed a series of evaluation and reconstruction work
Let post-disaster buildings not only be temporary footholds and resettlement sites
It has become a place where people's hearts can take root
