Abstract
The
UK
construction industry is beginning to take notice of Post Occupancy
Evaluations (POE) of completed buildings. POE studies have found that
actual energy consumption in buildings often bears no resemblance to
design predictions and low-level comfort problems persist. In the
UK
, there are a growing number of supporters for the routine use of POE in
the construction industry. This paper discusses the in-use performance of
an Advanced Naturally Ventilated secondary school building in the
UK
. The building features open plan classrooms, night cooling and
automatically controlled solar shading and ventilation openings.
The study includes (a) long term monitoring of the thermal
environment in classrooms, (b) short term analysis of environmental
conditions and (c) parametric analysis of environmental conditions using
advanced thermal modelling. Monitored data indicates that the summertime
overheating criteria was achieved using the night cooling strategy and
that the open plan classrooms achieved very good Indoor Air Quality (IAQ).
However it was noted that there was a trade off between the IAQ and the
acoustic environment. It was found that the internal environment on the
second floor could be improved significantly by controlling sky-light
openings using information about wind direction. The information from the
study is being fed back to the design team and findings incorporated in
future projects.
Key words: natural
ventilation, post occupancy evaluation, thermal comfort, passive cooling,
school.
