9 Bioclimatic Designs - Low Carbon Materials Processing

Fig. 8 – Trace of internal & external temperatures – typical floor (2 nd )
As commissioning and fine tuning continue a better performance is evident. Internal
temperatures are up to 10 degrees lower than external temperatures. The
commissioning has highlighted that the air flows throughout the building are at least
as complex as suggested by the BP Institute.
1. Stability of internal temperature against external. Internal conditions fluctuate
approx. 2 degrees against approx. 16 degrees externally, 2. Effect of night cooling
the exposed internal structure – typically depressing the temperature by 2 degrees
for the start of the next day, 3. Typically 1 degree variation between front and back
sections of building, 4. Internal temperatures are depressed up to 10 degrees
during daytime.
