Modern Workplace Environment Pre- and Post-Occupant Satisfaction in Modern Office Hot-Desking Systems: A Comparative Study of Workplace Environments

This study investigates the impact of hot-desking implementation on indoor environmental quality (IEQ) and employee work experience in commercial office environments. The research was conducted in two office buildings (Office G and Office H) located in Los Angeles, USA, characterized by a warm and dry climate. A comparative pre- and post-implementation design was adopted, using historical data collected in 2017 (pre-COVID) and field measurements conducted in 2024 (post-COVID). A mixed-method approach was applied, combining environmental measurements and occupant feedback. Key IEQ parameters, including air temperature, relative humidity, CO2, particulate matter (PM2.5/PM10), lighting, and noise, were collected using calibrated sensors at multiple locations. At the same time, Post-Occupancy Evaluation (POE) surveys were conducted to assess comfort, satisfaction, and productivity. In Office G, 24 participants completed the survey, with similar data collected in Office H. Responses were recorded using a 7-point Likert scale covering thermal, air, visual, and These data include key IEQ parameterss. Two sample t-tests and correlation analyses were used to compare pre- and post-conditions and examine relationships between IEQ and occupant responses. Results show that hot-desking led to a slight improvement in overall IEQ, especially in air quality and lighting, while thermal and acoustic conditions remained stable. Improved IEQ was associated with higher satisfaction and perceived productivity, with some differences across age and gender groups. These findings suggest that, within the studied context, hot-desking can be applied without reducing comfort and improving workplace performance when supported by proper environmental control.
