Description
The study aims to assess the extent to which daylighting strategies are implemented in selected
convention centres. The objectives are to identify daylighting strategies utilized in selected convention
centres, and evaluate their adequacy. The study focused on convention centres as they are commercial
buildings that consume large amounts of energy. Three convention centres were conveniently selected at
random in Lagos State, Nigeria due to the easy access for observation. The study used the mixed-method
approach. 100 questionnaires were issued to respondents in each centre and 131 were retrieved and used
for analysis. The data collected were descriptively analyzed using the Statistical Package for Social
Sciences (SPSS), and the results were sorted from the highest to the lowest in terms of their mean item
score (MIS), and presented in tables. The sizes and functions of the identified strategies in the case studies
were analyzed in relation to standards, and the findings were discussed in relation to other researches. It
was revealed that the selected convention centres did not utilize daylighting strategies effectively as they
rely largely on artificial lighting. The findings further revealed that daylighting is not very well considered
at the conceptualization stage of this building typology. The pieces of evidence show that as the elements
in a space are considered, adequate daylight can enter that space and create the potential for energy savings
in lighting. Further studies can be carried out in existing convention centres in other developing countries
to explore the influence of daylighting on energy savings. This paper provides valuable information on
acceptable daylighting strategies based on the observations made which could be incorporated in
convention centres from the design stage, and insight into measuring the adequacy of daylighting strategies
in convention centres in comparison with other researchers’ findings as discussed below.
