The Post Occupancy Evaluation Surveys of the ZERO-PLUS four pilot case studies in UK, Italy, France and Cyprus has been completed and the scientific results confirm the high quality of the projects' design, detailing and construction.

ZERO-PLUS case studies underwent Post Occupancy Evaluation (POE) surveys, covering different seasons and hours of the day, including interviews of tenants by surveyors.

Data analysis showed high satisfaction with individual parameters (ventilation, temperature, noise, lighting, odours) and overall satisfaction with the buildings.

Many questionnaires highlight thermal and acoustic advantages of building envelopes, and praise lighting. Renewable Energy Sources integrated in the case studies, were indicated as one of the reasons for changing behavioral patterns.

Building users indicated preference to operate windows and doors in order to achieve thermal comfort and improve Indoor Air Quality (IAQ) before operating HVAC.

Post Occupancy Evaluation (POE) deals with the overall assessment of ZERO-PLUS project performance, mainly the interface between data considered objective (spot-measured, monitored) and those considered subjective (questionnaires, interviews, surveys).

In the current context, the former data were coupled with the latter in an attempt to draw a comprehensive picture of the actual use and usability of the buildings perceived as systems, including the physical building attributes, incorporated mechanical and other systems and equipment, and the actual use by the tenants.
