Implications of Indoor Air Pollution in Business Buildings in Nigeria

Abstract

Abstract. Globally, most individuals spend 90 per cent of their daily routine time indoors. Outside air pollution adds to the toxins created in interior spaces owing to heating and cooling, which has a substantial impact on a person’s health (an illness that results in mortality and morbidity) and productiveness. This study investigates the implications of air pollution on interior air quality in commercial buildings such as event centres in Kogi State, Nigeria. A descriptive research approach was used with a questionnaire administered to 120 participants chosen through a random sampling procedure in business buildings. Findings indicated that inadequate windows and tiny door size, including the absence of mechanical cooling devices, were linked favourably with higher temperature in the interior but negatively with its moistness. The results show that indoor air quality has negatively impacted the workforce performance and productivity of the customers, and the efficiency of their activities in the event centres. The implication for practice is that designs of apertures should be large enough to allow for cross ventilation. At the same time, mechanical cooling systems should be included in the design for optimal interior air quality. The study recommends synergistic interventions from academics, policymakers, and occupational practitioners to improve the national standards and their implementation for the management and regulation of indoor air quality in inside settings in Nigeria.
