Dr. Linda Xiao, Associate Professor of BSE, gave a welcome speech introducing and expressing thanks to Prof. Simonson.   Prof. Simonson discussed Heat and Moisture Exchangers for Energy-Efficient Buildings. Energy-efficient buildings are important because the heating and cooling of buildings accounts for 30% to 50% of energy consumption and greenhouse gas emissions in developed countries. Furthermore, the demand for cooling is expected to increase by 30 times over this century due to climate change and increased demand in developing countries. Although this a major topic with major R&D efforts around the world, Prof. Simonson’s niche is moisture transfer in energy exchangers, which is important for frosting in cold climates and for cooling of buildings in warm and humid climates. The presentation covered some of the recent research supervised by Prof. Simonson at the U of S, including research on membranes and liquid desiccants for HVAC applications, frosting in heat and moisture exchangers, fouling of energy exchangers and solid desiccants for energy wheels.   Towards the end, the participants took the opportunity to raise meaningful questions during the Q&A session and provoke further discussions. Prof. Simonson is a Professor of Mechanical Engineering at the University of Saskatchewan (U of S) in Saskatoon, Canada. He received Bachelor’s (1991), Master’s (1993) and Doctoral (1998) degrees in Mechanical Engineering from the U of S and has been a professor at the U of S since 2001. In 2007/08 and 2014/15, he was a visiting professor at the University of Oulu in Finland. Prior to becoming a faculty member at the U of S, he spent 4 years at the Technical Research Centre of Finland. Prof. Simonson is a Fellow of ASHRAE, an Associate Editor of the ASME Journal Thermal Science and Engineering Applications and an editorial board member of Energy and Buildings and the Journal of Building Physics. In February 2015, he received the Natural Sciences and Engineering Research Council of Canada (NSERC) Synergy Award for Innovation, which “recognize examples of collaboration that stand as a model of effective partnership between industry and colleges or universities”. The nomination was titled “Venmar and University of Saskatchewan – Research and Development of a New, Revolutionary HVAC system”.

BSE Seminar: Ventilation of Residential Buildings in Hong Kong: Issues and Possibilities for Improvement on 12 August 2016

A CPD seminar, which was supported by the Environment and Conservation Fund (ECF 23/2011) of the Hong Kong Government and the Department of Building Services Engineering (BSE) of The Hong Kong Polytechnic University (PolyU), was held on Friday, 12 August 2016   This seminar has attracted about a hundred of students and professionals from building and construction industry who have interests in building envelope design and ventilation Professor MAK Cheuk-ming from the BSE Department and his postdoctoral fellow Dr. AI Zhengtao were responsible for the seminar presentations. The seminar was 1.5 hour long and intensive. Seminar Topic: Ventilation of residential buildings in Hong Kong: issues and possibilities for improvement   In the seminar, the speakers introduced the importance of indoor air quality and ventilation of residential buildings as well as the objectives of their study. They talked about ventilation in air conditioned an d naturally ventilated residential buildings. Based on their study, several possible ventilation strategies for air conditioned residential buildings were examined and the short term mechanical ventilation strategy was recommended. Owing to the moderation of local wind field and the accumulation of traffic related pollutants in street canyons, low ventilation rates and penetration of outdoor pollutants are two key risks involved in naturally ventilated residential buildings. Some opening configurations were evaluated, suggesting that careful envelope design to adapt to the high density urban environment is one of primary solutions to maximize the utilization of natural ventilation.   The seminar has richly inspired professionals to a deeper understanding of building envelope design for ventilation of residential buildings The results may help arouse professional’s awareness of sustainable building design.
