Windmill House

Sensitivity characterises the architecture of this uncertified Passive House on the southwestern coast of Ireland

Nilan Compact P AIR9

Tucked away in the green, rolling hills outside Hillsborough, County Down, Windmill House is an award-winning family home constructed following the core principles of Passive House.

The thermal bridge-free construction and exceptional air-tightness, both of which were achieved by GP Developments’ strict attention to detail, from the outset. The installation of triple glazed windows, U-values which far exceed legislation and mechanical ventilation with heat recovery, mean the owners of Windmill House now enjoy a superior level of thermal comfort and exceptional indoor air quality. 

The beating heart in this building is the Heat Recovery Ventilation System. Not only is the air quality and thermal comfort regulated by the Nilan Compact P,  a small integrated heat-pump provides all the hot water required for five shower rooms and a bathroom. This entire system, bespoke to Windmill House, was designed and installed by Nilan.Green.

The holistic approach employed by Nilan.Green ensures that this all-electric home offsets its energy consumption with a photovoltaic array and battery storage. This not only keeps the heating, hot water, lights and automation going, but also supplies clean energy to two car chargers installed in the garage. 

As well as the clean energy credentials at Windmill House – it also boasts state-of-the-art Smart Home technology. All electrical outlets are wired individually, giving the home-owners a comfortable, truly tailored lifestyle based on their daily routines and a more enjoyable and comfortable home experience.

Harnessing their comprehensive experience of thermal design and academic knowledge of thermodynamics, award-winning architects Marshall McCann enlisted GP Developments and Nilan.Green to implement their vision of minimalist design, concealing state-of-the-art technology.

After winning the Building and Architect of the Year Awards 2021’s ‘Single House Building of the Year’, Passive House Designer and owner of Nilan.Green, Garrett Quinn said;

“I am delighted that Windmill House has won such a prestigious award.

As principal coordinator of this project I am so proud to see a young family move into Windmill House. Knowing that their children will benefit enormously from the exceptional internal air quality is so rewarding.

By improving the home environment, we can achieve a better health standard (with less reliance on the health service), while reducing fuel costs and leaving people with more money in their pockets to spend in their local economy. Not to mention the environmental benefits for our children’s future.

It’s 2021, Passive House should be standard by now!”

Truly deserving of its accolades, Windmill House is a perfect example of how much more efficient we can be in the delivery of family homes.
