Indoor Air SIG


The Indoor Air and Environment Special Interest Group (IA&E) of the Clean Air Society of Australia and New Zealand is interested to promote discussion and debate on the state of knowledge and the quality of indoor air, and on related environmental health concerns. The group encourages research, education, community awareness and management of issues related to this topic.


The IA&E group has concerns that the importance of indoor air quality is not adequately addressed in our Society. There is no national framework for assessment, monitoring, control or management of indoor air quality issues. One of the aims of this group is to work towards the establishment of an appropriate national body for better understanding and management of indoor air quality.

Indoor Air SIG Webinar

11.30am - 12.30 AEDT - 1.30 - 2.30 NZDT
You are invited to attend a webinar on the topic of: 

Improving Indoor Air Quality in New Zealand Classrooms
with a Solar Ventilation Unit: The Air Particulate

Dr Mikael Boulic      
Massey University, New Zealand                                                         

Abstract: The first part of this webinar will be about sharing preliminary results from the solar ventilation in primary school project presented last July, at the Indoor Air Conference (IA 2016), Gent, Belgium (20 minutes). The second part will be a quick focus on highlights from the IA 2016. This will be a good opportunity for people who did not attend IA 2016 to get a quick summary (10 min). 

There is a lack of research on particulate matter (PM) concentration within the New Zealand (NZ) schools. A study was conducted in two NZ classrooms over a three-week period. A solar ventilation unit (treatment) was activated in one classroom. PM10 was monitored inside the classrooms plus outdoors. Hourly-resolved coarse and fine PM was collected onto substrates for elemental composition (ion beam analysis) and source apportionment (positive matrix factorization). PM10 concentrations increased within both classrooms during school hours when outside level remained stable. PM10 increase was not related to outdoor conditions, but to children’s activity re-suspending dust. The solar ventilation unit had a positive impact in decreasing the PM10 concentrations by a factor of 1.5 in the treatment classroom. PM in the classrooms was predominantly from crustal sources (fine and coarse soil dust). There is a need for dust exposure mitigation strategies (carpet cleaning regime, dust reducing carpet) in NZ classrooms.

Biography: Dr Mikael Boulic is an indoor air researcher based at Massey University, New Zealand. He is a Principal Investigator in the Healthy Housing Research Group (2014 New Zealand Prime Minister’s Science Team Prize). In 2016, he was awarded a Health Research Council of New Zealand Emerging Researcher Leaders Award for outstanding research focused on improving indoor environment in New Zealand Primary Schools.

Mikael’s area of expertise is focused on the interface of the Building Technology and Public Health. As an emerging researcher, he has been involved in few intervention studies where he investigated the relationship between heaters, ventilation and the level of pollutants (mould, bacteria, chemicals and moisture) in homes and in classrooms. These studies had a strong sympathy for vulnerable communities with low income, Māori and Pasifika communities being particularly at risk through a higher burden of disease. Research on children’s environment and health is considered as a high priority for New Zealand.
