2. 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

3. 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

4. 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
