Existing building renovation models are static and fail to deliver measurable comfort improvements. They lack real-time controls and do not account for user-specific comfort needs, limiting their effectiveness and user satisfaction.

The high upfront costs of deep renovation and lack of accessible financing options – particularly for low-income or vulnerable groups – prevent large-scale uptake and exclude citizens from benefitting from energy efficiency improvements.

Building users often lack awareness of the link between their behaviour and comfort-energy performance. Limited engagement opportunities further weaken the social acceptance and sustainability of renovation outcomes.

Two performance-based Comfort-as-a-Service (CaaS) contracts will be signed – one for a public building and one for a residential block – linking payments to verified improvements in energy efficiency and indoor environmental quality.

Pilot buildings will be equipped with real-time indoor environmental quality (IEQ) and energy monitoring systems. These smart controls enable dynamic management of HVAC (heating, ventilation and air conditioning) systems to optimise comfort conditions and reduce energy consumption.

Thermal Acclimatisation Training (TaT) will be delivered to building users, helping them understand and adapt to energy-efficient comfort settings, which supports behavioural change and reduces rebound effects.
