1. Areas of interest/contributions to ANNEX 68 Subtask 2 : Pollutant loads in buildings Presentation of PANDORA Marc Abadie, Patrice Blondeau, Francis Allard University of La Rochelle (ULR), France 36thAIVC conference Effective ventilation in high performance buildings IEA EBC Annex 68 Design and Operational Strategies for High IAQ in Low Energy Buildings September 23 24, 2015

2. PANDORA PANDORA: A comPilAtion of iNDoOR Air pollutant emissions Database: emission rates of both gaseous and particulate pollutants from : Occupants and Occupant Activities Cleaning Products and Air Fresheners Construction and Decoration Materials Furniture Heating and Cooking Appliances Electrical Equipment Others Developed by LaSIE (University of La Rochelle) since 2009 A limited version of PANDORA is available at: http://lasie.univ-larochelle.fr/PANDORA-A-comPilAtion-of-iNDoOR 2

3. Emission rates Definition of Emission Rates: Gaseous pollutant: Pollutant mass per time, or Pollutant mass per time per surface area for materials, or Pollutant mass per source unit for occupant activities such as the use of printers, copy machines, smoking cigarette , or Pollutant mass per combustible mass or energy units for combustion products. Particulate pollutant: Particle number per time unit per particle size, and Particle density. 3
