Description
The objective of developing this database was to summarise all relevant published studies that have linked the thermal environment to office work performance within the most representative temperature range for office buildings (20 °C to 30 °C). We conducted a comprehensive literature review and collected the relevant published data into our database. A variety of combinations of keywords including temperature, thermal sensation, work, cognitive, and task performance, and office and commercial buildings, were used.
In total, we found thirty-five studies, in 29 peer-reviewed journal publications and 571 measures of performance, met our inclusion criteria. We normalised these measures using a method originally proposed by Seppänen et al. (2006; 2006). This method uses the change in work performance per 1 °C increment in temperature (λ%), which is measured in percentage per degree Celsius (%/°C). Our database comprised a total of 358 data points for λ%.
Furthermore, we developed a web-based interactive tool with an easy-to-use interface to visualize the relationship between temperature and office work performance. This tool can automatically calculate the model's equation and accuracy metrics via different data subsets and regression models.
