A measuring program in a naturally ventilated office building in Copenhagen was carried out to document the indoor climate and ventilation system performance during a year. It included a questionnaire regarding the perceived indoor environmental quality and physical measurements of thermal comfort, indoor air quality, air distribution in the building, air flow rates and infiltration.

The results showed that the temperature levels in general fulfilled the requirements for thermal comfort. In some parts of the building occupants complained of high and varying temperatures and draught. This was due to a combination of poor control of solar shading and a very high local heat load that was above the Danish recommendations for naturally ventilated office buildings. Both measured and perceived indoor air quality in the building was in general very high. The measured air flow rates was relatively high due to the need for cooling in the office building, while the level of infiltration was quite low indicating an airtight construction.
