Abstract
Thermal comfort is an important factor for the design of buildings that offers comfortable indoor environment for the wellbeing of building occupants. There are several residential building typologies at different locations in the world. These includes bungalows, duplexes and block of flats. Despite previous studies on thermal comfort in Nigeria, there is a lack of research data on the performance of different building types, especially in terms of thermal comfort. Hence, this study evolved to investigate three popular types of residential buildings in Nigeria. The research outcome aims to provide data for theoretical evolution on the thermal behavior of these building types. The paper used dynamic thermal simulation, natural ventilation mode to analyze three residential buildings in Lokoja, Nigeria using hourly weather data for a period of 10 years. The simulation results showed that the annual operative temperature for the three cases were 33.360C, 33.620C and 33.650C. This revealed that there is no significant difference between the operative temperatures of the three case studies. However, there were marked differences between both the monthly and annual solar gains of the case buildings. The total annual gains for the three case studies were 24118.27kWh, 20497.90kWh, and 39493.09kWh. Although there was no significant difference in the performances of the case buildings, there performed differently in terms of both operative temperature and solar gains. The simulation results confirmed thermal discomfort in residential buildings in the study area. This calls for improvement in the design of residential buildings in the study area to enhance thermal comfort and reduce energy demand due to overdependence on mechanical cooling systems. This study has provided data that is expected to guide design professionals and other stakeholders in the building industry in their decisions regarding the thermal performance of residential building types in the study area and in similar climates.
