Occupants' Preferences for Regenerative Architectural Elements in Enhancing Thermal Comfort in Corporate Headquarters Buildings

Abstract

Thermal comfort remains a major concern in corporate office buildings located in tropical climates, where high temperatures often increase dependence on energy-intensive cooling systems. Regenerative architecture offers opportunities to improve indoor environmental quality through environmentally responsive design strategies. However, limited attention has been given to occupants' preferences for regenerative architectural elements that enhance thermal comfort. This study assessed occupants' preferences for regenerative architectural elements and their perceived suitability for improving thermal comfort in selected corporate headquarters buildings in Abuja, Nigeria. The study utilized data obtained from a broader mixed-methods investigation of regenerative architecture and thermal comfort. A structured questionnaire was administered to occupants of the selected buildings. Of the 277 questionnaires distributed, 264 valid responses were returned, representing a response rate of 95.3%. Data were analysed using descriptive statistics, including frequencies, percentages, mean scores, and ranking techniques. The findings revealed that natural ventilation systems were the most preferred regenerative architectural element (Mean = 4.71), followed by daylighting strategies (Mean = 4.62) and shading devices (Mean = 4.58). Indoor and outdoor vegetation (Mean = 4.49), courtyards and open-air spaces (Mean = 4.33), vertical green walls (Mean = 4.24), green roofs (Mean = 4.19), and water features (Mean = 4.02) were also positively rated but ranked lower. The results indicate that occupants prioritize passive regenerative design strategies that provide direct and observable thermal comfort benefits. The study concludes that occupant-centred regenerative design in corporate headquarters should prioritize natural ventilation, daylighting, and solar control strategies to enhance thermal comfort and reduce dependence on mechanical cooling systems.
