Abstract
Approximately 90 million of Nigeria's residents are
without electricity access; this represents 12.5% of the world’s
population without access. Nigeria is challenged in meeting goal 7
of the sustainable development goals (SDGs) due to inadequate
power generation to meet demands, poor transmission networks
and insufficient investment. Proposing energy audits and
efficiency measures, such as proper housekeeping, retrofitting
electrical systems and installing renewable energy sources, will
help reduce energy consumption and mitigate the country's
energy crisis. This study conducted on a residential building in
Nigeria found that retrofitting the building lighting system could
achieve annual savings of as much as 230kWh and have a
payback period of 9 months with a return on investment (ROI) of
126%. The retrofit of the pump system is expected to save
182kWh within a payback period of 2 years and have an ROI of
50%. The installation of solar panels and retrofit of batteries is
expected to save 3MWh at a capital cost of N300,000, with an
ROI of 26% and a net present value of over N690,000. These
measures would also reduce a total of 1.97 tons of greenhouse gas
emissions annually
