Abstract Globally, energy consumption in buildings takes up the largest proportion of world's energy production. This consumption is more in developing countries including Nigeria and Least Developed economies than the developed worlds. Researches are therefore, currently been geared towards reducing energy consumption due to the global problem of insufficient energy needed to meet the demand and the attendant environmental issues associated with the production based largely on fossil burning. In Nigeria, consumption in buildings takes up about a third of the total electricity production with Lagos accounting for the larger percentage of the total energy production due to the fast rising population, teeming economic growth and increased rate of construction across the state. This paper thus investigates the energy consumption in residential buildings (1004 Federal Housing Authority Estate), in Lagos state. Survey analysis approach was adopted in this work. Field trips to the study area were conducted, measurements were taken and questionnaires were administered to occupants. The design features of the buildings were 248 achieved through series of demonstration works carried out in the analysis using ETTV equation. The study established that the perlite plaster has a lower thermal transmittance value (U-value) when compare to that of cement hence a better energy reducing material option in building construction. The impact of ETTV on the energy consumption of residential buildings leading to a reduction in building heat load was also established in the study.
