This detached family home in Athenry, Co. Galway, was the first certified passive house in the West of Ireland. Construction was completed on time and within budget in 5 months, another 5 months of meticulous planning preceded the build.
An exceptional independent air-tightness test result of 0.28 air-changes per hour (ACH) was achieved in this timber frame construction, indicating there are effectively no draughts anywhere in the house. This also guarantees a long life for the building by eliminating the possibility of moisture penetrating and damaging the structure.
LED lighting was used throughout the house to further reduce energy demand. In total 70 x 2 watt lights were installed, the total energy demand for lighting is 140 Watts, less than the usage of two standard light bulbs! A solar thermal system provides hot water all year round and a small wood burning stove supplies the building’s small space heat demand, and boosts the hot water in winter time when the solar system is less efficient.
