Ventilation inspections promoting a good built environment

Well-functioning ventilation is a prerequisite for good indoor climate and efficient use of energy, which both represent substantial economical values. Anyone who realizes the value of quality assured ventilation also realizes the importance of adequate ventilation inspections. This keynote summarizes two Swedish examples, one legislative, the other voluntary. Lars Ekberg is an adjunct professor in indoor climate technology at Chalmers University of Technology, Gothenburg, Sweden. He also works as a consultant at CIT Energy Management AB, a subsidiary of Chalmers Industriteknik. Lars' research is focused on the chain of issues from human needs and wishes, via formulation of requirements to the design, construction and management of healthy, comfortable and energy-efficient buildings. His work spans from residential buildings on one end, to non-residential premises including schools, offices and laboratories on the other.
