AbstractThis test method was developed by the National Research Council Canada (NRC) to determine the initial performance of indoor passive panel technologies (IPPT) in their removal of formaldehyde and toluene gas as well as assess re-emissions of captured gases and harmful by-product formation. This new protocol builds on existing sorption-based standards to evaluate performance of both sorptive- and PCO-based IPPT in removing indoor formaldehyde and toluene. Considering that some PCO-based IPPT may be influenced by sorptive effect, this new protocol differentiates removal performance attributed to light illumination and sorption. This protocol uses an improved chamber with proper control of air velocity and turbulence level to simulate indoor conditions instead of a photoreactor chamber. In addition, the chamber utilises indoor lighting (as opposed to UV) as a source of illumination to better represent indoor applications. By testing by-product formation, this new protocol is the first to address protection of building occupants to harmful pollutant exposures. The project was funded by the Government of Canada’s Clean Air Regulatory Agenda to develop three protocols for evaluating the effectiveness of “IAQ Solutions”. It was prepared by NRC researchers under the guidance of a Technical Advisory Committee (TAC) assembled for this task, whose members included participants representing Federal and Provincial Agencies, Industry Associations, Non-Governmental Organizations (NGOs), Municipal governments, and Standards Association from Canada. The protocol also considered consultations of stakeholders comprising builders, researchers, industry partners and health professionals. The contributions of the TAC members and stakeholders to this work are gratefully acknowledged. Compliance to the test method and to the data interpretation developed in this test method is voluntary.
