Preliminary Framework on Application of Means-End Chain for Participatory Housing Personalisation AYOOSU, Lorakaa The Means-End-Chain model, originally developed to elicit customer values through consequential benefits and attributes of a product in marketing research, is becoming increasingly productive in other practical disciplines such as architecture and housing. Although initial applications of the means-end chain in Architecture were mostly in housing choice and preference at individualised level, it is progressively being applied in the personalised design of mass housing schemes and housing and urban upgrade programmes at the community level. Therefore, this scoping review examined the Means-End-Chain theory as a model with high prospects in Architecture and related disciplines and its application for participatory housing personalisation at the community level. The study found that preferences for housing, like any other product-choice behaviour, have value orientation directed towards achieving specific goals, which can be analysed using its physical attributes. An attempt was finally made to develop a preliminary research framework for the application of MEC in indigenous housing personalisation through community participation.

Variation Of Natural Ventilation with Floor Level and Orientation of Classrooms AYOOSU, Lorakaa In recent times, the multi-storey school building has emerged as a new trend in Nigeria due to land cost in the urban area and population increase due to urban migration resulting from insecurity in rural areas. Among other factors, the floor level and orientation of space are believed to affect its natural ventilation. More so, electricity per capita consumption in Nigeria is very low, suggesting passive ventilation in the building. The ventilation in the classroom is usually through wind-driven systems (windows). The study sought to establish the variation of natural ventilation among classrooms on different floor levels and orientations. In the ex-post facto design, instruments were employed to observe wind speeds and directions in and around selected classrooms, in a school building block with two wings on three-floor levels, with a perimeter fence, and located in a built-up residential area. The classrooms on the ground floor were half-opened casement windows, while those on the upper floors had sliding windows. Data generated were subjected to descriptive statistical analysis. In the longer wing classrooms, the mean wind speed and standard deviation obtained were 0.17m/s and 0.123 on the ground floor; 0.15m/s and 0.104 on the first floor; and 0.18m/s 0.126 on the second floor. Corresponding results in the shorter wing classrooms were 0.12m/s and 0,077 on the ground floor; 0.11m/s and 0.095 on the first floor; and 0.17m/s and 0.126 on the second floor. Ventilation coefficients were 0.13, 0.11 and 0.13 respectively on the ground, first, and second floors in the longer wing classrooms, while those in the shorter wing classrooms were 0.13, 0.12 and 0.19 respectively. The findings revealed some direct variation in natural ventilation with the floor level in the studied classrooms, which was more manifested as the level of the floor increased upwards. In conclusion, the floor level and orientation affect wind-driven ventilation. As such, there is also a need for further field studies on more suitable cases (higher floor levels) to ascertain the level of significance of this variation and the optimisation window area base on floor levels for orientation for wind-driven natural ventilation.

Window Glazing for Efficient Daylighting and Energy Saving in Tropical Climate AYOOSU, Iorakaa Moses Implementing sustainable architectural design solutions, such as daylighting, can effectively decrease the energy consumption of lighting systems. The reduction in energy usage directly affects the energy requirements of heating, ventilation, and air conditioning (HVAC) systems, particularly in buildings located in tropical climates that require more cooling. The paper aimed to minimise energy consumption by achieving a harmonious equilibrium between advantageous natural lighting and excessive solar heat. The study would ultimately lead to reduced energy consumption and provide a guideline for architects to enhance sustainable building designs in Nigeria. This study employed simulation methods to determine the optimal glazing type that achieved satisfactory daylight while effectively controlling thermal heat gain, decreasing cooling load, and minimising energy usage. The study utilises performance simulations to identify glazing types for lowering energy consumption and improving building daylighting performance through rigorous comparative analysis. The simulation procedure was executed using Design Builder software, with Energy Plus as the simulation engine, for a building in Makurdi, Nigeria, considering the Southern-East and Southern-West window orientation. This analysis concludes that choosing the appropriate type of glazing is crucial for minimising energy consumption.

Daylighting Performance Assessment of Side-Lit University Lecture Theatres in the Hot-Humid Climate of Makurdi in Nigeria Ayoosu, M. I., Lim, W.-Y., & Leng, P. C Daylighting is required to enhance visual comfort; whereas its illumination provides renewable functional interior lighting for specific programmes. Hence, this study examines the levels of daylight illumination for teaching and learning in two lecture theatres each located at the Federal University of Agriculture Makurdi (UAM) and Benue State University Makurdi (BSU) in Makurdi, Nigeria. The two buildings selected for the daylighting performance employed post-occupancy evaluation approach. A digital camera was employed to take photographs, whereas digital light meters were employed to evaluate the levels of illumination on the work plane. The results showed that 80% of the study space has inadequate indoor daylight illumination quantity and distribution as well as poor daylight ratios of 1.1and 0.9 for UAM lecture theatre and BSU lecture theatre, respectively Hence, the lighting conditions in the selected buildings fall short of the international lighting benchmarks (IESNA). Therefore, a pragmatic daylight design strategy is required to enhance daylight levels in the lecture theatres for energy-saving and visual comfort as well as onwards design and fusion in the national building code.
