18th century building becomes a low-energy modern house
Ambitious upgrade and extension project in Co. Kildare, Ireland. An 18th century farmhouse was transformed it into an elegant family home with a striking-yet-sensitive modern extension — all while embracing a healthy and fabric-first approach to retrofit combined with clever heating system design that has brought them from a G to an A3 rating.
Ventilation duties for both the new and old buildings are courtesy of a decentralised LUNOS heat recovery ventilation system – a solution that enables low energy ventilation without running ductwork. The large house requires a dozen LUNOS e2 decentralised heat recovery ventilation units, a LUNOS ego HRV unit and thee low energy extract fans.
Project type: Retrofitted 200 sqm rubble-built house (dating from c.1730) with approx 200 sqm cavity wall extension to the rear
Architects: Maxwell Pierce and Mesh Architects
Contractor: Pat Doran Construction
Location: Kildare, Ireland
Building: Single-Family house
Ventilation system supplied by Partel: LUNOS decentralised demand-controlled heat recovery system throughout. 12 x Lunos e2 units, 1 x Lunos ego, and 3 x low energy extract fans.
Final calculated efficiency relative to the house: 85.22% (according to DiBT) / 73.22% (according to the Passive House Institute). Overall volume flow: 195 m3/hr. Specific power consumption of heat recovery units: 0.10 W/m3/hr.
