The Passive & NZEB Water & Wastewater Expo, part of the All-Ireland Water & Wastewater Expo 2026, focuses on advancing energy efficiency, conservation, and high-performance building standards in Ireland. Taking place on 2nd–3rd April 2025 at the National Arena, Sport Ireland Campus, Blanchardstown, Dublin, this event explores the latest innovations in Nearly Zero Energy Buildings (NZEB) and Passive Construction. These building approaches prioritize energy reduction, renewable energy integration, and superior energy performance to meet Ireland’s evolving Building Regulations. Attendees will gain practical advice on compliance, energy ratings, and technologies that enable sustainable construction and reduce energy consumption.

Ireland is a leader in promoting Nearly Zero Energy Buildings (NZEB) and Passive Construction to align with national climate goals and the EU Energy Performance of Buildings Directive. Since the NZEB standard became mandatory for all new buildings in 2020, the construction industry has rapidly adopted advanced technologies such as high-performance glazing , airtight construction , and heat recovery systems . Ireland’s Sustainable Energy Authority (SEAI) is driving further innovation with support for on-site renewable energy generation and demand-controlled ventilation systems . As energy efficiency and decarbonization become top priorities, Irish builders and developers are focusing on integrating heat pumps , group heating systems , and cutting-edge materials like nanotechnology to bridge the energy gap sustainably.
