Passive designed house Liscannor

The project in Liscannor, County Clare, is a remarkable example of a passive house designed with a timber frame construction. This project emphasizes energy efficiency, sustainability, and comfort while minimizing energy consumption. Architect Miles Sampson designed the house, and Niall Dolan carried out the construction, underscoring a commitment to environmentally responsible architectural practices.

Key details of the "Passive House – Timber Frame" project in Liscannor, Co. Clare:

Ground floor insulation: The ground floor is insulated in a cold bridge-free foundation system that sits directly on the ground, achieving an impressive U-value of 0.15 W/m²K. This design minimizes thermal bridges and reduces heat loss.

Wall build-up: The wall construction includes a 300mm thick thermally broken stud with cellulose insulation. The external face consists of cement render board, panelvent, and the internal face comprises OSB ranking board with a service cavity, resulting in a U-value of 0.13 W/m²K.

Roof build-up: The roof structure features 400mm thermally broken roof trusses with cellulose insulation and an insulated service cavity, achieving a U-value of 0.13 W/m²K. This design effectively insulates the roof, reducing heat loss.

Airtightness level: The project boasts a remarkable airtightness level below 0.6 air changes per hour (ACH). This high level of airtightness helps maintain consistent indoor temperatures and reduces energy consumption.

Heating system: The heating system for the house is the Nilan Compact, known for its energy-efficient ventilation and heating capabilities.

Triple glazed alu-clad windows: The use of triple-glazed alu-clad windows enhances insulation, reduces heat loss, and contributes to the overall energy efficiency of the house.

Biorock non-electric treatment unit: The project features a Biorock non-electric treatment unit, which is an eco-friendly and sustainable solution for wastewater treatment.

The project showcases a comprehensive approach to sustainable and energy-efficient residential construction. The combination of architectural design, insulation, airtightness, and sustainable wastewater treatment aligns with modern goals of creating eco-friendly and comfortable living spaces while minimizing energy consumption and environmental impact.
