Assessment of the Energy Efficiency Programmes within the Internal Operations of Nairobi City County Government, a case study of CBD Region

Energy Efficiency (EE) is an emerging concept in the management of public institutions. The main objective of the study was to assess the Energy Efficiency Programmes (EEPs) of the Nairobi City County Government (NCCG) within its internal operations. It did this by conducting an energy audit, identifying & determining success rates of the EEPs and developing a sustainable implementation model for these programmes. A case study was analyzed for electrical energy consumption of Nairobi Central Business District with a focus on the sub sectors of street lighting, building facilities and traffic lighting. The results of this study indicated that there have been EEPs instituted by NCCG and these measures have led to a 32% reduction in energy consumption in city hall complex between the years 2016 and 2021 with the EEPs including replacement of fluorescent luminaires with LEDs, behavior change among others. For the street lighting, 184 lamps have been replaced with LED options translating to 4% conversion rate with some not operational due to faults and vandalism. Finally traffic lighting has a 65% LED conversion rate with incandescent lamps being 14,833 in 2016 and down to 9,754 in 2021. The economic analysis shows that the EEPs implemented are able to derive economic value to the NCCG within a medium term plan. Various Barriers to implementation has also been highlighted and how to mitigate them. The business model developed allows departments to follow a standardized process in setting energy targets, implementing energy efficiency measures and tracking financial, environmental and energy savings.
