Health effects of urban heat islands

Discussion with Rainer, Jouni, and Alex 6.7.2010

Three main topics for THL to assess in the [Mega case study]]:

concentration change of outdoor-to-indoor pollutants due to insulation
- Stuttgart has basic data on buildings, both Northern and Southern Europe. They will send information about them.
- Estimates will be made by THL about how fast the better insulation in buildings will change (rought estimate 1-2%/a of house stock gets improved)
  - Based on this, changes in ventilation will be estimated. Easiest is to calculate old and new/renovated buildings separately with high/low ventilation? Another aspect is incoming air filtration, which reduces some pollutants. How many houses are better insulated?
- Matti has building and heating information from several countries. In addition, Otto has done work on Finnish ventilation and insulation issues. Jouni will task with both of them.
- Jouni will check Ullas work on radon mould.
- Make sure that all relevant pollutants are included: formaldehyde, environmental tobacco smoke, radon, PM. do we have background concentrations? Jouni will talk with Matti.
- Who calculates the whole chain? THL based on Hilary's and Fintan's ERFs.
- The official MCS scenarios have insulation, marcus ustutt energy modeller has insulaton data. comes from
wood burning more ->more pm?
- more wood burning as a source to indoor air
- cenral stoves vs open stoves in the room latter has high emissions to indoor air. marko
- look both indooor especially and outdoor emissions
- centel south europe

marko!

stutt tells what can provide
