Indoor environmental quality and hygrothermal performance in energy retrofits
Residential building energy retrofits are integral to EU climate actions, but their impact on indoor environmental quality (IEQ) and occupant comfort must be assessed to guide future renovation programs. Housing surveys at European and national levels have highlighted quality issues related to IEQ and occupant health. It remains crucial to involve SMEs and stakeholders in monitoring retrofit techniques' effects on IEQ and the hygrothermal performance of building structures to ensure sustainable and healthy buildings.
The RIAQ project aims to inform and engage SMEs, building stakeholders, and occupants by establishing common protocols for IEQ assessment and evaluating the potential for enhancing IEQ, energy efficiency, and climate resilience in buildings. It will contribute further evidence on improving IEQ in the existing residential building stock. The project develops assessment protocols and advocates sustainable retrofit techniques, facilitating the transition to a circular and resource-efficient economy while addressing climate change adaptation and energy efficiency in retrofitted buildings.
Moreover, the RIAQ project seeks to accelerate the capabilities of peripheral communities, SMEs, and national and international inspection services in providing energy retrofit solutions. It fosters connections among SMEs interested in sustainable energy retrofit solutions, offering insights into emerging technologies, upcycling opportunities, and product development strategies that embrace circular economy principles. Leveraging the expert networks established through RIAQ, the project also informs and engages SMEs, stakeholders, and communities about relevant legislation and policies related to national and transnational circular economy initiatives.
