An energy-efficient “DemoHouse” developed by Kildare County Council has officially opened in Maynooth, with staff from Maynooth University supporting the project through research and community engagement. Part of Kildare County Council’s Decarbonising Zone strategy, the initiative aims to showcase how sustainable retrofits can make homes more energy-efficient, comfortable, and accessible while reducing carbon emissions.
The DemoHouse, a standard 1990s home located in Maynooth, has undergone a major retrofit as part of the project. Upgrades include internal wall insulation, triple glazing, an air-to-water heat pump, rooftop solar panels, and improved airtightness to significantly enhance energy performance. The house also has smart systems to track indoor air quality and energy use in real time.
Researchers from MU— Professor Fabiano Pallonetto and Dr Amy Fahy, who are the Principal Investigators for the Research Ireland-funded National Challenge Fund RENEW project, along with Dr James McGrath —are collaborating with Kildare County Council to monitor the building’s performance over the coming year. The data gathered will help inform best practices for retrofitting older homes and reducing the carbon footprint of the residential sector.
The partnership reflects MU’s commitment to supporting local sustainability and climate action efforts. “It’s fantastic to see a real-world project like this taking shape,” said Dr Amy Fahy. “The DemoHouse gives us a space to work with the community on energy, health, and environmental topics, all in one.”
The house is also a practical learning hub for local residents, community groups, and schools. MU researchers are helping to deliver workshops and outreach activities on-site, exploring the benefits of retrofitting and sustainable living practices.
Maynooth Green Campus and MU’s Estates team donated furniture and electrical equipment, supporting the project’s emphasis on circular economy principles. Throughout the retrofit, reusing materials and reducing waste were prioritised.
Accessibility and biodiversity were also key considerations. The DemoHouse includes universal design features such as level-access doorways, an accessible kitchen and bathroom, and a stair lift. Outside, the garden has been enhanced with pollinator-friendly planting, a wildlife pond, and sustainable drainage systems.
The DemoHouse is a key part of Kildare County Council’s commitment to Ireland’s 2030 climate action targets, aiming to cut emissions by 51% and achieve net zero by 2050.
