This paper aims to reinterpret a set of Key Performance Indicators (KPIs) that influence users\u2019 satisfaction from different perspectives. Fieldwork was carried out in an office building following a detailed review on KPIs by conducting user surveys. This study highlights the need to organize specific indicators to focus on the usability of workplaces and, where and when required, through an iterative process, understand the user perception of performance indicators in usage conditions. This methodology is applicable for organizations to understand the main existing in-service problems, and could improve the building\u2019s performance over time. Survey results showed that hygiene was the most recognizable influence on users\u2019 satisfaction and indoor air quality was the less well-known in the assessment results. User perception results can be compared to other office buildings results to benchmark good practices and should also be investigated for the post-COVID-19 period.<\/jats:p>","DOI":"10.3390\/infrastructures6030045","type":"journal-article","created":{"date-parts":[[2021,3,15]],"date-time":"2021-03-15T11:38:58Z","timestamp":1615808338000},"page":"45","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["User Perception on Key Performance Indicators in an In-Service Office Building"],"prefix":"10.3390","volume":"6","author":[{"given":"Teresa","family":"Pestana","sequence":"first","affiliation":[{"name":"Department of Civil Engineering, Architecture and Georesources, Instituto Superior T\u00e9cnico, Universidade de Lisboa, Av.
