The seminar commenced with a welcome speech and speaker introduction by Prof. CHEN Qingyan, Director of the PolyU Academy for Interdisciplinary Research (PAIR). In his presentation, Prof. Cao stated that urban environment engineering seeks to apply system engineering to solve complex urban problems. He highlighted that interdisciplinary research that combines scientific and mathematical approaches is crucial for understanding the mechanisms and laws concerning the complex interactions between humans and the ecological environment. Prof. Cao emphasised that the modelling of urban pollution involves a mix of techniques, including remote sensing, big data, computational simulation, the Internet of Things, artificial intelligence, digital twins, etc. He gave various project examples to explain how different techniques can be used for scientific monitoring, fast prediction, assessment and regulation of urban pollution. To conclude, Prof. Cao pointed out that advancements in urban environment modelling and intelligent control can build the scientific foundation for sustainable urban development.

The lecture commenced with a welcome speech and speaker introduction by Prof. WANG Zuankai, Associate Vice President (Research and Innovation). In his presentation, Prof. Chen first gave a brief introduction to the United Nations’ 17 Sustainable Development Goals (SDGs) as well as the SDG monitoring practices in Mainland China. He pointed out that the Nation has adopted the high quality sustainable development concept, which emphasises harmonising the social, economic and environmental aspects in national development. Next, he elaborated on a pilot project that he led to measure Deqing County’s progress towards SDGs using geospatial and statistical information. The project was selected by the UN Department of Economic and Social Affairs as one of the first 16 good SDGs’ practices in 2020. After that, Prof. Chen shared that the achievement of sustainable development requires holistic and systematic research to build a digital governance system that can provide the basis for the scientific and orderly development of national territorial space. He also explained how territorial space sustainability studies can help unveil and analyse various patterns, such as the distributions of population, enterprises and public service facilities, and the relationships between them. To conclude, Prof. Chen introduced the national program on the development of the Realistic Geospatial Landscape Model (3dRGLm), which can generate digital description and representation of the real 3D geospatial spaces. This new geographic information system can support the Nation in achieving natural resources management and high quality sustainable development.
A question-and-answer session moderated by Prof. DING Xiaoli, Director of the Research Institute for Land and Space (RILS) and Prof. WENG Qihao, Associate Director of RILS, followed. The online and on-site audience engaged in a productive discussion with Prof. Chen.

The lecture commenced with a welcome speech by Prof. CHEN Qingyan, Director of PAIR, followed by a brief speaker introduction by Prof. Christopher CHAO, Vice President (Research and Innovation).
In his presentation, Prof. Brilakis first gave a brief introduction to digital twins (DT), pointing out that DT plays a central role in digital transformation. Next, he elaborated on the application of DT in the construction industry and explained how DT is involved in the planning, design, construction, maintenance and operation processes. He introduced research conducted at the University of Cambridge on inexpensive methods for generating object-oriented infrastructure geometry, detecting, and mapping visible defects on the resulting DT, automatically extracting defect spatial measurements, and sensor and sensor data modelling. Prof. Brilakis also provided examples of how these resulting DT are further exploited in design for manufacturing and assembly (DfMA), mixed-reality-enabled mobile inspection, and proactive asset protection from accidental damage. To conclude, Prof. Brilakis stated that DT, smart materials, data science, and automation & bobotics, constitute important digital assets for driving sustainability, and pointed out the future development directions in these areas.

In the lecture, Prof. Batty gave an overview of the development of the science of cities in the last 50 years. Drawing on the system approach and complex theory, he explained that urban science involves top-down and bottom-up thinking; it is a systematic, complex and evolving discipline built on knowledge in social physics, economics, transportation and numerous scientific methods that yield theories. He illustrated this with city morphology examples from the UK and the Greater Bay Areas (GBA) generated by large-scale computer models. At the end of the lecture, Prof. Batty described some challenges with fractal geometry, size and scaling, networks, and building models currently faced by the field, and he suggested the way forward for the discipline.

Geospatial information science is a discipline that focuses on using geospatial information technology to understand people, places, nature and processes of the earth. IoT refers to Internet of things, the combination of sensors, software and other technologies to connect and exchange data with other devices and systems over the Internet. The era of IoT brings us opportunities and challenges for geospatial information science. In the keynote, five characteristics and three scientific issues of geo-spatial information science in the era of IoT are summarised.

Physicist Geoffrey West has found that simple, mathematical laws govern the properties of cities -- that wealth, crime rate, walking speed and many other aspects of a city can be deduced from a single number: the city's population. In this mind-bending talk from TEDGlobal he shows how it works and how similar laws hold for organisms and corporations.

Welcome to Crash Course Geography hosted by Alizé Carrère! This course with be split into two parts. In the first half, we will focus on physical geography or the processes and phenomena of the physical world both above and below the Earth's surface. We'll ask questions like, "why is the seafloor so young when the Earth is so old?" or try to identify why winds and ocean currents are so important to life on Earth. Then we'll turn our focus to human geography and explore the ways people occupy the Earth's surface. Like how we've moved, settled, and used the land, resources and space. But ther'e not always a clear line dividing the physical and human, because really, geography is telling the story of the Earth. We'll hope you'll join us on this journey starting November 30, 2020!

Constant Air Volume System or CAV System is an all-air type HVAC system that uses constant air volume while the temperature of the supplied air is varied to achieve the desired heating or cooling. We discussed the single duct single-zone system, single duct multizone system with reheat coiled, and dual duct system. In CAV System Air handling unit fans are running at a constant speed resulting in a lot of energy consumption for supplying the air. In the Multizone reheat system, a lot of energy is consumed in heating the already cold air, so the CAV system is not energy efficient. That's CAV system is strictly restricted by many energy codes.

How does a Drinking water treatment process work?, Drinking water treatment plant process animation: Here working of drinking treatment plants with detailed drinking water treatment processes and unit operations are discussed. Drinking water from the river, pond or local water bodies comes in drinking water treatment plants through various water treatment processes, like aeration, coagulation, filtration, and disinfection, etc. The aim of drinking water treatment is to produce and maintain water that is hygienically safe, aesthetically attractive and palatable in an economical manner. Thus, Before arriving at your tap, drinking water is treated in the drinking water treatment plant.
