“…energy auditors are able to identify energy losses, optimize process efficiency, and recommend energy-efficient technologies, resulting in significant energy savings. According to a study in [22], energy audits can result in energy savings of up to 30% annually. Energy Editor analyzes energy bills and energy consumption patterns, conducts interviews with facility managers, and perform on-site inspections to assess building energy performance, HVAC systems, lighting systems, and other equipment [23].…”

The energy sector in Africa, particularly in countries like Uganda, plays a pivotal role in shaping economic development, social progress, and environmental sustainability. This study delves into the nuanced interplay between energy policies, legislation, and their real-world consequences in Uganda. By employing a case study approach, this research investigates the multifaceted impact of Uganda's energy policies and legislation on various stakeholders, including government institutions, businesses, and local communities. This study provides an overview of Uganda's energy landscape, highlighting the challenges faced by the nation in ensuring a stable and sustainable energy supply. It then meticulously examines the evolution of energy policies and legislation over the past few decades, analysing their formulation, implementation, and effectiveness. Through qualitative and quantitative analyses, this research assesses the socio-economic consequences of these policies and legislations. It explores how regulatory decisions have influenced energy accessibility, affordability, and reliability for urban and rural populations. Additionally, the environmental impact of energy policies is scrutinized, focusing on their contributions to climate change mitigation, natural resource conservation, and the promotion of sustainable practices. The study also evaluates the social repercussions, including the empowerment of local communities, employment generation, and overall improvements in the quality of life resulting from energy policy interventions. This research critically examines the challenges faced during policy implementation, such as bureaucratic hurdles, financial constraints, and political influences, which often hinder the desired outcomes. It identifies key lessons from Uganda's experiences, offering valuable insights for other African nations grappling with similar energy challenges.

“…The advantages of LED lighting is its small size, high reliability, high colour-rendering index, long life, To begin an EPC programme, an energy audit is required to determine the current load, energy usage and energy conservation measures (ECMs). Energy audit refers to a surveying technique that consists of an analysis of the energy usage of an organisation [36]. The energy audit is used to 'diagnose' the weak points in the building's energy usage system, harness the latent potential, and instil energy saving responsibilities [37].…”

A Rational Plan of Energy Performance Contracting in an Educational Building: A Case Study

Energy performance contracting (EPC) is the best solution for an educational building to implement energy conservation measures (ECMs) because of its high capital expenditure and operational expenditure needed for retrofit and maintenance. It is also considered a win–win mechanism for organising building energy efficiency retrofit projects. It aims to assist educational buildings in acquiring new high-efficiency equipment and maximising energy use reduction, as guaranteed by energy service company (ESCO). This study developed an EPC model using regression analysis, in which the inputs are based on the data collected during the preliminary energy audit in University A. As a result, with a quantum sharing ratio of 0.95/0.5 for ESCO/University A, the forecasted energy savings from the proposed ECMs, chiller optimisation and replacement, lighting retrofit, and energy management system are estimated to save 25.6% energy use, which reduces 5,672,057 kilowatt-hour (kWh) in electricity consumption; saves RM 2,762,291.76/year; carbon dioxide (CO2) mitigation equal to 3,771,061.22 kgCO2/year; return of investment of 4.2 years with a 5% interest rate; and building energy intensity of 93.55 kWh/m2/year. A sensitivity analysis of various quantum sharing ratios found that the saving value of ESCO is inversely proportional to that of University A as the client when the quantum sharing ratio for the former is increasing.

“…Even if the consumer uses only linear loads, the current harmonics in the resonance conditions can flow through power transformer from other users [45], thus causing increased energy loss in the transformer. Both distribution system operators and end users should be concerned about the quality of electric power [46]. Most power transformers are designed to supply power to linear loads, so they cannot operate at their rated load with significant distortion.…”

Two prototypes with energy efficiency calculations have been developed to enable real-time efficiency assessment and data collection. The results of the experiment demonstrate that the use of microprocessor technology and the Internet of Things can significantly improve the efficiency and accuracy of energy audits in power transformers. The prototypes developed in this study provide real-time efficiency assessment and data collection, enabling more effective energy management and cost savings for industrial users. During the experiment, it was found that resonance can cause the same losses as a poor power factor of the system, highlighting the importance of addressing energy quality issues in addition to energy efficiency. These findings have important implications for energy efficiency policies and practices in the context of climate change mitigation and rising energy prices.
