The aim of this work package was:

To evaluate the performance of existing ad-hoc buildings designed and constructed specifically as energy-efficient naturally ventilated buildings

To identify the advantages and shortcomings of natural ventilation strategies

To specify the overall design and construction conditions required for achieving successful natural ventilation

The Monitoring CampaignsThe Monitoring Campaigns The 19 buildings selected were monitored under winter and summer

conditions

The following parameters were measured in all of the buildings: Temperature Internal air quality (H2O, CO2, …) Ventilation rate Wind outdoor: direction and velocity Wind indoor: velocity

The parameters were measured in 4 rooms and 1 corridor for a minimum of one week

Final Conclusions (1...)

There were 8 key findings from the 19 building monitoring programme:There were 8 key findings from the 19 building monitoring programme:

1. The challenge is to provide comfortable conditions within an energy efficient building.

2. It is essential to understand what natural ventilation actually is.

3. Ventilation for IAQ should optimise both IAQ and energy efficiency

4. The required air flow rates for summer comfort are much higher than for IAQ control and the thermal mass of the building must be accessible

2. It is essential to understand what natural ventilation actually is.

3. Ventilation for IAQ should optimise both IAQ and energy efficiency

4. The required air flow rates for summer comfort are much higher than for IAQ control and the thermal mass of the building must be accessible

Final Conclusions (2|) 5. Achieving comfortable conditions in the summer requires more than

just high ventilation rates

6. Successful design involves more than simply estimating air flow rates

7. The creation of an attractive environment for innovation is extremely important

8. Natural ventilation can be an attractive option, but NOT the only option
