  1. Health Impact of Actions on IAQ SINPHONIE Project kick-off meeting 10-12 November, REC Conference Center, Szentendre Hungary Eduardo de Oliveira Fernandes IDMEC-FEUP

  2. How to assess the health impact? In the DG Research funded Coordination Action on Indoor Air Quality and Health Effects, EnVIE, a robust modelling tool was developed to quantify the most important health risks attributable to IAQ The common unit for all the different burden of disease (BoD) assessments was DALY/year (disability adjusted lifeyear), developed and supported by WHO, for the quantification and comparison of a wide variety of health effects (Murray et al. 1996, Prüss-Üstün et al. 2003 and 2006). WHO estimated national BoDs for diseases and symptoms in DALYs

  3. EnVIE Model

  4. Method (1) The EnVIE-IAIAQ modelling tool was first used to quantify the total current European IAQ related burden of disease (BoD)and to attribute it on the diseases, exposure agents and sources included in the model. The given and main focus of IAIAQ was on • Assessing the public health impacts, i.e. achievable reductions to the above modelled IAQ BoD, of some current European IAQ policies; and on • Predicting the potential impacts of some alternative and future IAQ policy-scenarios.

  5. Method (2) The assessment method can best be understood as a four dimensional matrix. The dimensions are diseases, exposure agents, sources and policies. A change in the implementation of a policy is assumed to induce (a) proportional change(s) in the release(s) of one or more of the sources, respectively (a) proportional change(s) in the level(s) of one or more exposures, and finally (a) proportional change(s) in the level(s) – attributable to IAQ – of one or more of the disease(s).

  6. The exposure – health relationship models in IAIAQ

  7. Typical and high end levels of some indoor air contaminants and contributions of the indoor sources to both typical and high end indoor air exposure levels in Europe, and comparison to WHO (I)AQ Guidelines source: WHO 2000 and 2006a

  8. The IAQ associated BoD attributed to the key exposure agents

  9. The IAQ associated BoD attributed to thekey sources of exposure

  10. IAQ associated DALYs in 26 European countries (2005+/-5) Blue: national BoD in DALY\year*million from indoor exposure to pollution originating from outdoor air. Red: contribution from all indoor sources

  11. European countries divided into 4 quartiles according to BoD caused by exposures from indoor sources.

  12. BoD/year*million from ETS exposure beginning from poorly or non controlled conditions to the conditions mandated in the 2010 legislation.

  13. Potential DALY/year benefits at the 10th year of implementation of 10 IAQ policies in EU-26 for DALY/year*million, divide by 484 [million inhabitants], i.e. 400 000 DALY/year corresponds to ca. 2000 DALY/year*million

  14. Distributions of the national public health benefit potentials of the 10 assessed policies in the 10th year of implementation (DALY/year*million) within the EU-26 countries Levels from left to right: min – 1st quartile–median–third quartile–max.

  15. Temporal increase of the annual public health benefits of the alternative IAIAQ policy scenarios in EU-27 as the implementation of the different policies slowly saturate the building stock.
