The Irish social housing sector faces major challenges in improving home environments and sustainability. Ageing infrastructure, harsh weather, and inadequate management responses contribute to poor living conditions, leading to mould growth and worsening health. In a County Dublin social housing block, children and vulnerable individuals suffer from bronchiolitis, breathing issues, chest infections, and mental health decline due to mould exposure (Conneely, 2025). Despite calls for relocation, their health has already deteriorated, highlighting a widespread issue that harms residents and incurs high costs. The Sustainable Homes Integrating Non-Intrusive Environmental Sensors Research Project (SHINE) aims to improve living conditions by identifying root causes and solutions. Through interviews with 28 stakeholders, including housing officials and residents, SHINE explores the use of non-intrusive environmental sensors in social homes. These sensors provide real-time insights, warning residents of mould risks by monitoring condensation over time. This proactive approach helps prevent issues, reducing management costs, hospital visits, and energy use. Long-term, SHINE seeks to integrate these technologies into social housing policy, promoting sustainability and better health outcomes.
