Abstract
Getting light into the building entity in a clever way is an important stride to designing
energy efficient buildings. Learning how to use daylighting, in an efficient way while having
control will reduce energy demands in buildings and also facilitate a good visual comfort for
users especially in a developing country like Nigeria where most trade fare take place using
artificial lighting which increases operational cost. Most Exposition tend to use artificial
lighting because proper daylighting design has not been integrated into the building. This
study identifies different daylighting techniques that will reduce operational cost and at the
same time, create a good visual experience. Literature on daylighting were studied, in which
the advantages of daylighting in buildings were identified, different daylighting techniques
and system were examined and various ways daylighting can reduce operational cost. The
research methods adopted where exploratory case study, experimentation, visual survey of
the various features inclined to the research work. Quantitative data collection method where
adopted through personal observation /field survey, sketches, photographs and case study
check list as data collection instrument. Case studies of relevant exhibition Centre buildings
were analysed using variables such as the building envelope shape, geometry and location
of aperture, surface characteristics, special distribution of light, illuminance ratio, colour
rendition and visual noise, model of three case study buildings were carried out and run
through simulation soft wares such as Ecotect, Radiance and daysim using data from
metrological department. The various material properties used in the modelled building
under observation where altered in terms of their “u-factor” “R-value” and Solar Heat Gain
Coefficient (SHGC) and it was observed that energy consumption in terms of lighting was
reduced by 35%. An important finding of the research was that a conscious proposition that
will fuse daylighting as a major design consideration in term of materials and design
considerations is essential for a successful daylighting design for buildings. This finding
affects the design process from optimizing building orientation, the perfect size, form and glazing treatment for windows, working with bright interior surface and shading for visual
comfort. For the research design, atrium, laminated glass, and light shelves was appropriate
for use. The implication of this finding opens a new dimension to the design of Exposition
centres.
