About the Seminar

Technical Seminar on Ventilation - from Neighbourhood to Indoors

Date: 28 September 2017 (Friday)
Time: 9:30am - 12:30pm (Registration will start at 9:15am)

Venue: Chamber 1b, Innocentre, 72 Tat Chee Avenue, Kowloon Tong


BEAM Plus Neighbourhood that launched in December 2016, is designed to assess project performance of a development project and help project owners to incorporate a broader framework of urban sustainability principles at the early planning stage for subsequent project implementation. In this assessment tool, outdoor environmental quality is concerned to safeguard the health, comfort or well-being of general public, as well as aspects of performance that improve quality and functionality. Good planning on neighbourhood and building ventilation can reduce the potential increase in urban heat island effect and provide sufficient quality of outdoor air provision for indoor built environment.

On the other hand, energy reduction and sufficient ventilation for indoor environmental quality are also concerned in other BEAM assessment tools (New Buildings, Existing Buildings & Interiors). In this technical seminar, two speakers will share their experiences on building and city ventilation in Hong Kong as well as more energy efficient and healthier approach to demand control ventilation.

Programme Details

Session 1 - Too Hot? The Challenges and Opportunities of Building and City Ventilation in Hong Kong

Our city differs from those in Europe and Americas, and also in the rest of China or Asia as Hong Kong is one of the most compact and tallest. In the last decade, the high temperature events have occurred more frequently, but the wind in our city being significantly weakening, in addition to the persistent urban haze.

Based on the study on building and city ventilation in the past 17 years, the hypothesis has come that our high-rise and compact city offers not just challenges, but also opportunities to design our building and city climate right. The challenges can also arise from other aspects such as education and land supply. In term of building ventilation and air conditioning, room pressure design, difficulties of full commissioning, need of return to basic physics, and understanding how would our air-conditioned buildings perform in a passive mode will be discussed in this session. In term of city ventilation and climate, the importance of right building density and height, urban heat island circulation and how to minimize high temperature events will also be discussed.

Session 2 - Healthy, Airside Solutions to Significantly Reduce Your Building’s Carbon Footprint

In the face of significant energy costs and concerns over global warming, buildings are receiving increasing scrutiny to reduce their carbon footprint and cut their energy expenses while still being sustainable and providing a healthy indoor environment. For many buildings, outside air is the largest single driver of both a building’s energy efficiency and its indoor environmental quality however the results of using such approaches as economizers and demand control ventilation to optimize outside air have been mixed at best. This session discusses and presents case studies on a new, more energy efficient and healthier approach to demand control ventilation as well as describes how economizers can be operated more reliably with greater energy efficiency in educational, commercial, and healthcare facilities.
