But over 75 % of the global potential in demand - side response lies in buildings, with space heating, water heating and air conditioning loads contributing the most.

Location: Cameron Close, Freshwater, Isle of Wight Completion date: August 2015 Budget: Total scheme costs circa # 4.9 m Passive house certification: Part certified with remainder pending Space heating demand (PHPP): 14.4 kWh / m2 / yr Heat load (PHPP): 9 W / m2 Primary energy demand (PHPP): 98 kWh / m2 / yr Environmental assessment method: Code for Sustainable Homes level 3 Airtightness (at 50 Pascals): 0.48 ACH Energy performance certificate (EPC): B 84 - 88 Thermal bridging: Details developed to minimise thermal bridging, concentrating on critical junctions and window installations.

For instance, ground source heat pumps tend to have higher efficiencies than air source units during the heating season due to the relative stability of ground temperatures below certain depths, though air source units — which involve much lower capital costs — have closed the gap in recent years as manufacturers have refined their design, and there is evidence to indicate that space heating demand in many Irish buildings may be peaking in Ireland's frequently relatively mild but windy weather, as the guide to air source heat pumps in Issue 24 of Passive House Plus discussed.

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.

Prof Nick Eyre highlighted that in the IPCC's Fifth Assessment Report, mitigation efforts to reduce energy demand made up 50 % of decarbonisation pathways, with a focus on energy efficiency and the electrification of transport and space heating using existing and emerging technologies.

This means that the building fabric must achieve required levels of thermal insulation and airtightness, among other factors, to ensure a maximum space heating and cooling energy demand isn't exceeded.
