The Home Performance Index (HPI) is Ireland’s first national voluntary certification system for quality and sustainable residential development, developed by the Irish Green Building Council (IGBC). HPI provides a label for quality sustainable residential development, complimenting existing schemes used in the commercial sector such as BREEAM and LEED.
This project by Wain Morehead Architects (WMA), RIAI Practice Member having already obtained Passive House Certification and an A1 rating under the BER system, easily achieves nZEB in a truly sustainable manner. The criteria considered are:
- Health & Well being
- Quality Assurance
- Sustainable Location
Irish Green Building Council (IGBC) CEO Pat Barry said of the achievement: “This rating highlights the very high-quality features of this house and its sustainability credentials. The home was designed with a great focus on the wellbeing of the users. It has excellent day lighting, very good indoor air quality and is extremely energy efficient, meaning heating costs should be minimal.
The house has a Building Energy Rating (BER) standard of A1 and is Passive House certified. It was designed to have exemplary levels of water efficiency and should use up to 85% less than a typical home based on standardised usage.”
Achieving this standard is a credit to all involved including client, design team, contractors, and the manufacturers and suppliers who have risen to the challenge by providing sustainably sourced, ecological, cost effective and fully certified products we like to use to the market. For WMA, achieving this standard embodies their philosophy to deliver “…sustainable, performance driven Architecture.”
