Post Occupancy Evaluation of 23 Newly Renovated Apartments in Copenhagen:Occupants’ Perception

摘要

The present article is based on the post occupancy occupants’ perception of indoor air quality of recently renovated 23 residential apartments in Copenhagen. The apartments are equipped with novel mechanical ventilation systems. The apartments can be categorised in four, according to the design of ventilation systems. The analysis in present article is based on occupants’ perception of the temperature, indoor air quality and energy consumptions of their apartments. The study shows the perception of occupants of first six months of post occupancy. The study was carried out by conducting interviews with the tenants. 74% of the total occupants took part in the interviews. 83% of the interviewed occupants as an averaged spend more than 50% of their time inside their apartments. 37% of the total interviewed occupants were satisfied with the current performance of their apartments. Apparently the reason of dissatisfaction of occupants was the lack of maintenance of the HVAC systems. Another point raised by the occupants during the interviews was the missing provision of user control on ventilation system.
