Modern buildings are usually equipped with advanced climate conditioning systems to ensure comfort of their occupants. However, analysis of their actual operation usually identifies large potential for improvements with respect to their efficiency. Present study investigated potential for improvements in an existing office building – a Town Hall of Viborg, Denmark. Thorough field measurements of indoor environment and occupant satisfaction survey were conducted to identify and describe indoor environmental quality problems. Collected data were also used to calibrate computer simulation model, which was used for optimization of building’s performance. Proposed optimization scenarios bring 21-37% reduction on heating consumption and thermal comfort improvement by 7-12%. The approach (procedure) can help to optimize building operation and shorten the adjustment period.
