The final design of the house is being submitted to preplanning this week, after months of work with architect Stephen O’Leary from Rebel Design Studio. The design has undergone significant changes since the original concept, with the master bedroom taking on a central role in shaping the layout and features of the house. The Passive House Institute’s design course was taken by Stephen, but this will be his first Passive House project. ...
The Passive House Premium is a net generating house that contributes much more to the grid than it consumes. However, due to the lack of a feed-in tariff for solar PV in Ireland and its low annual cap, it’s not economic to generate excess electricity on-site. The house design meets the RIBA 2030 Challenge embodied lifecycle carbon emissions goal if wood is chosen for all building materials. PHPP estimates that the Primary Energy Renewable (PER) demand of the house is 38 kWh/m2/yr, which is well under the Passive House Classic and Plus standards but not low enough for RIBA 2030 or Premium. The house design meets the RIBA 2030 Challenge potable water use goal. However, it does not meet the generation requirement for Passive House Plus, requiring an additional 50% more solar panels to meet the generation requirement. Diverting excess solar energy to a thermal store can significantly reduce mains electricity consumption, making it possible to meet the Passive House Premium standard. ...
