In the beginning of 1998 a three-year European project, AIRLESS, was started to develop strategies, principles and protocols to improve and control the performance of HVAC-systems and its components for incorporation in codes and guidelines. Twelve institutes, universities and companies from seven European countries are involved in this project. Knowledge on why, when and how pollution is caused by HVAC-systems is still largely undefined. Therefore the first step in this project is to define and to investigate ways to prevent pollution. In the second step, protocols can then be defined to keep pollution away (maintenance). Strategies to decrease pollution caused by an HVAC-system together with strategies to lower the energy consumption can then be defined. The first step of the project is reported and discussed.
