Spatial Distribution of the Nature of Indoor Environmental Quality in Hospital Ward Buildings in Nigeria

Abstract

This study seeks to ascertain the spatial distribution of IEQ in hospital wards based on the physical measurement of the hospital ward units with different architectural features. Field survey was undertaken in the medical and surgical wards units of two case study Hospitals both located in Jos, Nigeria. IEQ parameter variables were monitored and recorded, and compared against recommended international standards for hospital facilities. Results show that the measurements of the IEQ parameters conditions in the selected hospital ward buildings, differ substantially depending on the ward design configuration and orientation, and also the outdoor weather condition. The indoor environment in the hospital wards had different thermal conditions because of variations in orientations, window sizes and air inlet/outlet. Building orientation, also affected the indoor daylight quality in each of the hospital ward buildings within the period of measurements. The Teaching Hospital wards whose orientation (NW-SE) allows the fenestration façade to fall within the sun path, maximised it for daylighting within the wards. It is therefore recommended that, the design of hospital wards for improved IEQ conditions should be such that proper attention is given to the orientation, floor plan configuration and window design for natural ventilation and lighting.

Analysis of the Morphological Design Features of the Hospital Physical Facilities in Southwest, Nigeria

“…Price and Lu (2013) also recommended the involvement of users for analysis to make the correct decisions in the design process. However, applied research in solving various aspects of hospital spatial design in Southwest Nigeria remains scanty except the few studies originating from the northern part of Nigeria which was conducted by Nimlyat, Anumah, Odoala and Benjamin (2018). The study focused on spatial distribution of indoor environmental quality (IEQ) in hospital wards based on the physical measurement with different architectural features.…”
