The interdisciplinary scientific group ''ProKlimA'' has begun a four-y
ear study into the causes of, and factors influencing, sick building s
yndrome. 16 buildings in different parts of Germany will be studied. T
he schedule for the field investigation comprises 2 or 3 main phases:
an inspection of the building and HVAC system, an initial questionnair
e survey of all occupants working in the building and a project consul
tation based on feedback from the data analysis. A second occupant que
stionnaire survey with simultaneous clinical tests and building measur
ements will be performed on a subsample of 120 occupants. After a seco
nd data analysis and project consultation, ProKlimA will decide whethe
r to carry out an intervention study in the building, or not. First re
sults from 8 buildings investigated during 1995/96 show high inter-bui
lding variations in psycho-social, medical and ergonomic factors, envi
ronmental variables, and design and maintenance of HVAC systems.
