The residence is a flat on the third floor of a 25 year old multi-storey building, covers an area of 140 m2 and is occupied by 4 persons. It is located at a suburban area north-east of the
centre of Athens and 300m away from a heavily trafficked road. Measurements were taken
both in the kitchen, living room and immediate outdoor area (balcony), while everyday
activities such as cooking, smoking, window opening, fireplace use and cleaning were
performed. The residence walls were painted 2 months before commencing the experimental
campaign and moreover, in the immediate outdoor area a number of pine trees were present,
a source of biogenic VOCs. More specifically, 24 hour averaged PM10 and PM2.5 and
continuous total VOCs and CO2 measurements were taken both in the kitchen and living room
areas. NOx, SO2 and O3 were measured both in the living room and outdoor area (balcony)
on fifteen minute intervals. The experimental campaign in the residence took place from
4/2/2006 until 19/2/2006. From 4 to 10/2/2006 all pollutants were monitored while the
occupants performed their daily routines, while from 11 to 19/2/2006 several ventilation and occupation scenarios were applied. It must be noted that a log book of activities was kept for
all indoor areas monitored (see Table 2).
