Well-being as a tool to improve productivity in existing office space: Case study in Alexandria, Egypt

Abstract

Background: The green building industry has significantly impacted the construction market, providing various sustainable solutions for the community. However, conventional green building standards have yet to adequately address occupant health and well-being, leading to challenges with performance. This has caused many businesses to take note of the latest report from the Bureau of Labour Statistics, which indicated that productivity in the US has dropped by the sharpest level since the 1940s [1]. Addressing these issues, organisations like International WELL Building Institute (IWBI) developed WELL Building Rating System (WELL), prioritising occupant health and well-being as critical components for improving performance and avoiding potential vulnerabilities brought about by sickness or pandemics. For this reason, this study will explore how to improve employee productivity within office buildings by bettering their overall health and well-being. Methods: The methodology is designed to collect data from traditional office design, new trended successful office designs, and the WELL Building Rating System to understand healthy building design. Additionally, using DesignBuilder computer software simulates natural daylight, ventilation, and thermal heat gain in the case study to compare implementation results to the base case result. Results: Showing thermal comfort, ventilation, and natural daylight significantly influence employees’ productivity. Implementing conducted design features from WELL achieved an average of 20.2%-35.6% decrease in thermal gain throughout the year, a 20% increase in airflow, an average 2.4%-6.5% decrease in Air temperature, enhanced temperature distribution by 7%, and direct sunlight minimum reduction by 9% in Winter and maximum 21.9% in Spring. Conclusion: Our research analysed that new design features in famous office buildings positively impact employee productivity. We particularly examined the features outlined by WELL Building Rating System to identify the most influential factors affecting occupant productivity. The results of this study informed recommendations for enhancing productivity in existing office buildings in Alexandria, Egypt.
