The measurement and model predictions of indoor ozone concentrations in museums.

In order to determine whether high outdoor ozone concentrations are transferred to the indoor climate of museums, a monitoring project was carried out on eleven museums, art galleries, historical houses and a museum library for 38 days over the summers of 1984 and 1985. The differences in indoor ozone levels between the buildings could be explained by differences in building and ventilation system design, and this was verified by a mathematical model. Peak indoor ozone levels were highest in building with no air conditioning but a high rate of air exchange with the outdoors. The lowest levels occurred in buildings with slow air infiltration as the only means of air exchange.
