CIBSE awards for technical papers on air quality and the implications for building retrofit

Two technical papers looking at indoor air quality and the implications for retrofitting and ventilating buildings have been recognised with awards by CIBSE as the best papers published in Building Services Engineering Research and Technology (BSER&T) Journal in 2018.
 
One paper examines different ventilation strategies for retrofitting buildings to ensure safe levels of indoor air quality and their effectiveness, while the other looks specifically at CO2 and the effect exposure to high levels can have on human cognitive performance.
 
Yiyi Chu, Peng Xu, Zhiwei Yang, Weilin Li won the Carter Bronze Medal for their paper entitled: 'Retrofitting existing buildings to control indoor PM2.5 concentrations on smog days: Initial experience of residential buildings in China’.
 
Their paper started with an overview of the growing worldwide attention and increasing evidence of the relationship between air pollution and adverse health effects – including detrimental effects on the development of lung function in children.  It considered the effectiveness of different retrofitting methods to control indoor particulate matter in existing buildings, looking specifically at a case study from Shanghai, China. Methods used included air tightness improvement, indoor positive pressure control with a fresh air system and an air purifier.
 
The Napier Shaw Bronze Medal was awarded to Gesche M Huebner, Tadj Oreszczyn, Robert J Lowe for their paper: 'Possible future impacts of elevated levels of atmospheric CO2 on human cognitive performance and on the design and operation of ventilation systems in buildings’.
 
Their research looked at predicted increases in atmospheric CO2 concentration by the end of the 21st Century and their possible effects on human performance, before examining the implications this has on the engineering of ventilation systems and associated energy use. The paper highlights the very limited research done on the effect of higher levels of CO2 on cognitive performance, as opposed to air quality in general, and the need for further study in this area.
 
The Carter and Napier Shaw Bronze Medals are awarded annually by CIBSE to celebrate the high quality research carried out in the building services industry. They are presented to the highest rated papers of the year on application and research respectively, published in the Building Services Engineering Research and Technology (BSER&T).
 
The prizes will be presented at the CIBSE President’s Awards Dinner in October.
