The Norwegian Opera House felt that the level of dust in the production of costumes and masks was too high. Many of the employees felt that the air was dry and the efficiency could be better, especially in the afternoon. It was clear that all this dust was caused by the production of costumes and masks and this dust was causing the annoyance. Around 50 people work in this department which is approximately 700m2.
Before Euromiljø came into the picture, the supplier of ventilation systems had done everything they could to solve the dust problem, without any success. Helge Wettre: ”They visit us every month to replace the filters and clean the air cleaners. If there are any problems in the meantime, they come over and solve the the problems immediately.”
