And in this case it seems to have delivered: a broad
brushstroke analysis kindly provided by Nick Grant for this article shows that when re-calculated using the new PHPP, the Beehive's space heating demand dropped to 20 kWh / m2 / yr, comfortably inside the Enerphit target
of 25, while the building appears to have avoided exceeding the overheating target (not to exceed 25C internally more than 10 %
of the time) by the skin
of its teeth.
