Leaders in Energy Efficiency

Guided by Passive House principles, Cosgrave houses are designed to use less energy, the team’s commitment to energy efficiency and sustainable design is recognised at the highest national level.

Pioneers of the green agenda, Cosgraves continue to develop homes that exceed the requirements of regulations. The energy efficiency of a Cosgrave home cannot be measured just by a BER Rating, it is deeper than that, it is in every detail of the fabric of the building and is validated through a series of quality control measures that ensure every Cosgrave built house really is a superior energy efficient home.

Guided by Passive House Principles the Team at Cosgraves invest in the fabric of the house to ensure it delivers sustainable living in terms of lower energy usage, improved comfort and reduced life time running costs.

In 2013, Cosgraves were recognised as the best of the best when the Sustainable Energy Authority of Ireland awarded them the Overall Environment Award for outstanding leadership in the field of energy efficiency. This is a very significant achievement as the award is open to all sectors and has never before been awarded to a house builder and is a highly valued endorsement of Cosgrave’s higher standards in energy efficiency.
