€224 annual estimated heating costs.

The client says: “The biggest change for us is that there has been very little forced heat or cooling input. It wasn’t unexpected, but the uniformity of temperature throughout the house is a pleasant surprise, and the fact that we don’t constantly have to turn boilers on or off or adjust thermostats is great.”


The architects are now monitoring the house for its energy consumption, indoor humidity, carbon dioxide, temperature, and for the energy production of the solar PV array. The house was also recently commended at the 2017 RIAI Architecture Awards in the sustainability category.

 Products installed:
  • Nilan Compact P unit, which includes an exhaust air heat pump combined with passive heat recovery ventilation
  • Nilan Air 9 air-to-water heat pump as back-up, which distributes heat via underfloor heating only during the coldest winter periods.
