EMPIR Workshop – TP Environment Matthias Richter Birte Mull 01/12/2015 Metrology for air pollutants and their interdependencies with the environment EMPIR Workshop – TP Environment Matthias Richter Birte Mull
Motivation EU Building directive (2010/31/EU) Higher energy efficiency Zero energy buildings until 2020 Construction Products Regulation (305/2011/EU) Annex I, No. 3: Requirements for hygiene, health, environment Limitation of emissions of dangerous substances (VOCs, particles etc.) from building materials into indoor/outdoor air Ad-hoc WG (leader: JRC) has formed to establish harmonized scheme for health-related evaluation of building products Goal: Products with low emission properties on the market Reliable metrology necessary Lower air change rates -> rising concentration of pollutants 01/12/2015 EMPIR-Workshop | INRIM | Torino
Motivation Indoor aerosols standardization: current issue of ISO TC 146 ”Air Quality“ Characterization by concentration and size distribution Several national and international standards available Not congruent with respect to terminology, measurands and applied working principles Harmonisation required 01/12/2015 EMPIR-Workshop | INRIM | Torino
Summary IEQ influenced by several parameters Indoor and outdoor air pollutants (VVOC, VOC, SVOC, ozone) Temperature Relative humidity Air exchange Presence of aerosols/particles Interdependencies are impacting measurements either under laboratory or real conditions PRT shall have a focus on Measurement of (V)VOCs and aerosols/particles Improvement of measurement strategies for airborne particles 01/12/2015 EMPIR-Workshop | INRIM | Torino
Project ideas Development of measurement methods for (V)VOCs Sorbent material TD-GC-MS/FID/PDD, HPLC, IC Investigations on indoor air chemistry Interdependencies VVOC/VOC/SVOC with particles/dust Indoor climate (temperature, relative humidity, air exchange) Investigations on comparability of measurement methods for particle characterization Support of standardization activities 01/12/2015 EMPIR-Workshop | INRIM | Torino
Project ideas Development of constant emitting reference materials for VVOCs to SVOCs Nanostructured glass as inert carrier material with tailor-made porosity and integrated reservoir Modelling of transport phenomena inside the material For QA/QC, calibration, generation of test gases Generation of (V)VOC gas standards For calibration, comparison with reference material, tests for (V)VOC-particle interactions 01/12/2015 EMPIR-Workshop | INRIM | Torino
