Feasibility study of the UXindoor framework in two public office buildings: A standardized approach to scoring indoor user experience with qualitative and quantitative techniques

A human-centered strategy is crucial for effective energy retrofits, as the subjective experience of occupants directly affects the energy performance of buildings. To address this, we introduce UXindoor, a standardized scoring framework for assessing the User eXperience (UX) of Indoor Environmental Quality (IEQ). UXindoor is a key component of the PRIME Energy-Indoor project, which aims to guide integrated building energy retrofits based on real energy usage and IEQ data. The framework utilizes questionnaires, handheld instruments, and IoT environmental sensors in a unitary assessment framework. This feasibility study presents the results of the pilot-testing of the framework in two public buildings in Thessaloniki, Greece over a six-month period from September 2022 to February 2023. The study discusses the advantages of the proposed system as well as its limitations.
