Abstract
This study investigated the daylighting status and strategies engaged in the selected museums of Southwestern states
in Nigeria. Museums are generally known as traditional places where artefacts are stored and displayed for the
purpose of entertainment, enlightenment, recreational, cultural and educational advancement purposes. The
integration of natural daylighting into museums spaces is an ambiguously critical factor especially as the sun rays
toed the paths and panes of fenestrations to the display points where the artefacts are positioned. The effects of
daylighting exposure to the museum artefacts depends greatly on the length of exposure to light rays and object
tolerance. The aim of this project is to investigate the daylighting status of museum design in order to improve the
architectural design in terms of associated energy-design indices with inclusive daylighting design strategies of the
ultramodern art museum for Oyo state. The study methodology engaged questionnaires, interview, literature reviews
and case study evaluation; in order to improve daylighting strategies in museum building. It also examined the
adequate features relevant for integrating daylighting strategies in the design of museum. Questionnaires were
administered and analyzed using Statistical Package for Social Science (SPSS) through descriptive analysis of the
data. The analysis showed that there are cogent parametric-energy design indices in the existing architectural designs
that are applicable in forms, spaces, materials, techniques, installation and strategies to museums in the tropical
climatic regions. It further showed that the use of clerestory windows, atriums, light tubes and anti-solar
glass/windows were considered to be most adequate daylighting features sufficient for daylighting optimization. It
finally recommended an architectural model design specific to all tropical museum (cultural) building species in a
holistic form and spaces, and planning. These would enable a high-level patronage and optimization for
entrepreneurial benefits within the confine of museums and other culture-related buildings in the tropical climate.
