Simulation Study of Thermal Comfort in Residential Building Types: The Case of Lokoja, Nigeria

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