Overview

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.
