Disaggregating primary electricity consumption for office buildings in Nigeria

This paper presents the findings of an investigation of electricity consumption in mechanically cooled Nigerian office buildings.  
A quantitative survey into 15 office buildings is conducted using questionnaire and observation techniques. The recorded primary data of monthly electricity consumption in three cities in Nigeria are tested for their alignment to the weather profile and regression analysis shows major discrepancies. Results show that cooling, lighting, and appliance loads account for approximately 40%, 12% and 48% respectively. Cooling consumption is not dependent on the climatic profile. This exercise is beneficial to prepare a primary dataset for validating building performance simulation results.
