Tigh-Na-Cladach

as PDF Tigh-Na-Cladach means house by the shore. One of these 10 semi-detached units of affordable housing for Fyne Initiatives overlook the River Clyde has been PassivHaus approved. Achieving PassivHaus standard was particularly challenging because the houses tall, slim shape creates an unfavourable volume-to-area ratio, has no south-facing windows (except for roof lights), no mains gas serves the site and the social housing budget was very tight.All of the houses, which measure 88.4m2, are constructed with a closed panel timber system; the walls and roof have a U-value of 0.09 W/(m2K). The floor has a U-value of 0.12 W(m2K). Triple-glazed windows are used throughout. The certified house is fitted with a highly efficient MHRV unit which has a heat recovery rate between 92 and 99 per cent, and duct runs are short due to the house design. A solar thermal system provides domestic hot water.
