The Wren Hotel

The Wren Hotel - NZEB Certified

The 137-room, nine-floor Wren Hotel is Ireland’s first NZEB Hotel using 100 per cent renewable energy. The Wren’s hot water, heating and cooling system design is based on a combination of highly efficient air-source and water-to-water heat pumps. The ventilation system captures 81 per cent of rejected heat using a thermal wheel, which also heats the incoming fresh air for free. With no fossil fuels being consumed, the hotel also avoids producing pollutants in its local urban environment.

The project by Alpha Mechanical Services Ltd. consisted of the full mechanical services installation to all 137 rooms in the hotel, the reception area, commercial kitchens, the bar, restrooms, back of house and associated areas of the hotel.
