The Faculty of Construction and Environment invites secondary school students to participate in the "Build a Smart City Competition 2025". This exciting opportunity encourages students to develop innovative solutions for transforming Hong Kong into a Smart City through workshops, demonstrations, lab visits, and discussions with esteemed researchers and members from our four departments, deepening your understanding of Smart City concepts while contributing to meaningful solutions. Don’t miss your chance to be part of this transformative experience! This competition comprises two parts: Part I: 2-day Workshop (28 Jun & 5 July 2025) All participants will engage in a 2-day workshop, immersing yourselves in a journey to explore the Smart City concepts. During this workshop, participants will be grouped according to the assigned projects, where you will participate in targeted sessions organised on the assigned project.  Part II: Presentation Day (22 August 2025) Following the workshop, participating teams will be given approximately 7 weeks to develop your projects. This phase will encourage teams to innovate and collaborate effectively. The presentation day will be held on 22 August 2025. Participants will have the freedom to choose the preferred presentation format.

The main purpose of this course is to provide the participants with the fundamental principles, skills and guidelines needed to carry out effective energy audits in accordance with the Buildings Energy Efficiency Ordinance. After taking the course, the participants would appreciate the approach to identify energy saving measures and perform quantitative analysis to predict the energy savings, environmental and economic benefits. Moreover, the participants should be able to measure and verify the performance of implemented energy saving measures.

The course will include a mixture of tutor led training, group discussion and delegate activities and will be assessed through a 2.5-hour online examination. Training will focus on the application of the greenhouse gas accounting and reporting guide developed by the Hong Kong SAR Government and will also cover practical carbon auditing skills.  Delegates will gain practical experience of GHG emission accounting and reporting calculations by completing a range of exercises and a case study Hong Kong office building. Participants will require MS Excel for the course case study exercise and also a laptop for the assessment. 

The course is designed for CPD, especially for members of CIE(HK), and also for HKIE – BS Div, CIBSE HK Region, & Energy Institute HK, all of which are the supporting organizations to the courses, and member rate can be applied to their members. 

Rundown Opening speech Part 1: Effective Ventilation Strategies in Hospital Environments Part 2: Outdoor Urban Morphology and Virus Transmission Part 3: Dynamics of In-Pipe Environment Q&A session [Effective Ventilation Strategies in Hospital Environments] Bio: Prof. Ling Tim Wong is the Associate Head and Associate Professor in the Department of Building Environment and Energy Engineering at The Hong Kong Polytechnic University. He received the Hans B. Thorelli Award in 2006 and 2011 and the Emerald Literati Network Award for Excellence. He is a working commission member (W062) of the Council for Research and Innovation in Building and Construction and organized the 34th CIBW062 International Symposium in Hong Kong in 2008. He is the Editor-in-Chief of the journal AIR. Abstract: This session will focus on the latest developments in effective ventilation strategies. We will explore critical design parameters, including Air Changes per Hour (ACH), optimal designs, and energy consumption considerations for healthcare-associated infections (HAls) and airborne virus transmission. The insights will inform practical guidelines to mitigate airborne transmission risks in General Human Occupied Areas (GHOAs), ensuring a safer environment for patients and healthcare workers. [Outdoor Urban Morphology and Virus Transmission] Bio: Prof. Chun Ho Liu is an Associate Professor in the Department of Mechanical Engineering at The University of Hong Kong. His research focuses on air pollution physics and chemistry, geophysical turbulence, and scientific computing. He currently investigates the urban atmospheric boundary layer, using large-scale computer models to examine how urban morphology modifies transport processes, refining land-surface parameterizations, particularly urban roughness.  Abstract: This seminar will explore how the physical layout of urban environments influences the spread of airborne viruses as passive scalars. We examine how urban structures can mitigate or exacerbate virus transmission. Key findings indicate that urban morphology-such as building density, street orientation, and green spaces-plays crucial roles in determining airflows and pollutant dispersion, affecting viral particle concentration and transmission likelihood in densely populated areas. [Dynamics of In-Pipe Environment] Bio: Ir Prof. Eric Wai Ming Lee is a Professor in the Department of Architecture and Civil Engineering at City University of Hong Kong. His research expertise includes building water supply and drainage systems and computational modeling of multi-phase flow. Prof. Lee is an active member of the HKIE and contributes to various technical committees under HKSAR Government departments. Abstract: Air pressure fluctuations in building drainage systems can cause problems if proper venting is not provided. Excessive positive pressure may push foul air into the building through the trap seal, while excessive negative pressure can empty the trap seal. To reduce these fluctuations, cross-vents connect the drainage stack to the vent stack every two or three floors. This study uses computational fluid dynamics techniques to investigate cross-vent design.

Hong Kong, a leading global metropolis, is uniquely positioned to spearhead sustainable urban innovation as net-zero targets gain urgency worldwide. Its towering skyline and intense energy demands place the building sector at a crossroads, wrestling with evolving regulations, technological advancements, and a pressing need for greater incentives and momentum. Fresh insights, practical case studies, and shared expertise are essential to overcome these hurdles. By harnessing ASHRAE’s globally esteemed codes, standards, and guidelines, the industry can pave reliable pathways to decarbonization. Join us for a transformative one-day seminar on 28 April 2025, delving into zero carbon strategies for building systems. A stellar speaker lineup will tackle government policy, green building design, and operational excellence, offering actionable solutions from trailblazing industry leaders committed to sustainability. This seminar equips professionals, engineers, facility operators, and policymakers with a vibrant platform to deepen their expertise, build valuable connections, and advance zero carbon initiatives across multiple fronts. Be a driving force in this pivotal dialogue! Attendees will benefit from exceptional networking at this in-person event, bringing together innovators, experts, and decision-makers. Unlock cutting-edge updates and collaborative strategies to stay at the forefront of the dynamic engineering field.
