PROJECT

Kilbride Lane Housing Development

The project involved 42 new 1, 2 and 3 bed social houses arranged with landscaped public spaces and a shared surface (54 UPH). The c 0.77 ha site was located southwest of Bray on a vacant infill greenfield property bounded on all sides by the rear of adjacent residential properties.

The development declared highly sustainable performance metrics achieving a BER of A2 (37 kWh/m2/yr) with an EPC = 0.200 and CPC = 0.200 using air to water heat pumps, an airtight rating of 1.6 m3/hr/m2 @50Pa and a thermal bridging factor of 0.03 W/m2K with water consumption of 79lpd. Over 60 materials were used with Environmental Product Declarations resulting in Life Cycle Assessment with GWP (Embodied Carbon) of 718kgCO2/m2 (incl measured waste but excl external works). The project implemented a 10 step plan for biodiversity, scored 87% in sustainable location, 76% in universal design and carried out post occupancy evaluations giving actual delivered energy consumption of 55 kWh/m2/yr (equating to primary energy 110 kWh/m2/yr) overheating at 0.9% and C02 levels of 626 PPM.

This project was the first multi-unit development in Ireland to be awarded gold certification (74%) under homeperformanceindex (HPI), a certification system developed by the Irish Green Building Council (IGBC) to assess quality and sustainability in new residential developments.

This project won several national awards including (i) Green Construction and Infrastructure Project Award 2023, (ii) Irish Building and Design Award 2022 – Public Sector Housing Project Of The Year, (iii) Irish Construction Industry Awards 2022  – Green Project of the Year and (iv) highly commended in Net Zero Construction Awards 2022 –  Housing Category.

The project was published as a case study in  Passive House + Issue 40 , as an exemplar project in Sustainable and Affordable Housing Report  by the World Green Building Council  and as a  case study  in Examination of innovation/ efficiencies in design of affordable housing  to be published by the Housing Agency.

Wicklow County Council is delighted to deliver these forty-two, much needed homes in Bray to the highest quality standard. To achieve the gold category of HPI certification from the IGBC for Kilbride Court demonstrates our commitment to deliver high quality energy efficient homes and to lead by example to tackle climate change in line with Climate Action and Low Carbon Development Act 2021. COADY Architects and their team, along with contractor KM Lynskey, are to be complimented on their achievements
