About this Special Issue
Global warming and resources scarcity have been still the main issues that have been addressed nowadays in both, economical and scientific conferences, and meetings. Therefore, industrial activities and engineering communities start a new era of energy-efficient uses. Conventional energy sources such as coal and natural gas are huge contributors to climate change. Reliance on conventional energy sources exposes consumers to price fluctuations and harms our health and environment. The world has witnessed a significant shift towards the use of renewable energy resources over the past couple of decades due to the reason of continuous depletion of fossil fuels. Renewable energy is the way to reliable and clean power. It gives significant advantages for the climate, health, and economy. Wind and solar energy need no water to operate and hence do not pollute water. In contrast, conventional sources can have a substantial impact on water resources. Energy efficiency is also essential to combat climate change. It is one of the easiest and most cost-effective ways to combat climate change.

Read More Ensuring access to clean energy for all—Sustainable Development Goal (SDG) #7—remains one of the most elusive SDGs in developing countries. This study reviews efforts to meet this goal in a developing community, namely Esaghem Village, Manyu Division in Cameroon. The efforts involved the use of a micro-off-grid solar PV system. The study employed primary data collected in-situ and from the project documents, and secondary data from electronic as well as conventional sources. The review is intended to highlight the impact of political, eco-nomic, social, technological, ecological, cultural and historical (PESTECH) factors on renew-able energy (RE) initiatives in a developing country. These are important but oft-ignored historio-cultural factors in the energy domain. The review reveals how one feature of indigenous African tradition, namely the self-help ethos can be harnessed to improve clean energy access in a developing country. It also showed how factors commonly associated with developing countries such as war, administrative centralization, bureaucratic corruption and ineptitude as well as poverty, thwart RE initiatives. The review underscores the importance of non-technical dimensions of RE projects and holds many lessons for the development, manage-ment and sustainability of such projects in developing countries writ large.

However, obtaining such data is time-intensive and monetarily expensive. This hinders the depth of analysis that can be done on these systems and negatively influences their large-scale uptake. This study proposes a novel generalised model of these systems that uses smart meter load profile data to model their cost-benefit. Using two years of half-hourly electricity consumption data from 5379 households in London, the model was used to examine how sociodemographic, tariff structures, and the choice of operational objectives of these systems, interact to influence their cost-benefit. The results showed that the proposed model produced reliable cost-benefit results within what is normally obtained in literature. The model demonstrated that applying one set of objectives to different customers leads to an inequitable distribution in benefits; rather, an optimal set of objectives for a given customer under a specific tariff structure can be found to produce a more equitable distribution in benefits across all customers. The proposed model is replicable and uses data that can be obtained easily and cheaply from smart meters, making it versatile for large-scale cost-benefit analysis by any electricity retailer.

Beyond Energy Efficiency in Building Sustainability: A Review of Emergy and Information for Systemically Characterizing Building Performance

Read More Sustainable buildings tend to maximize power and information rather than efficiency. The multidimensional concepts and tools provided by systems ecology and thermodynamics aid the understanding of building performance and sustainability as part of the global and complex thermodynamic phenomena in living systems—energy is not concentrated, but it flows, increasing the flow rate of useful energy. From such an extended macroscopic perspective, this paper addresses holistic eco-systemic criteria of building performance evaluation, focusing on emergy (spelled with an “m”) and information—the two critical indices of extensive and intensive analysis. Emergy aggregates the utmost and upstream energetic impacts, whereas information evaluates the structural pattern of the energy-flow distribution. These indices are theoretically correlated under the principles of ecological energy transformation and are often practically compatible. To clarify the definitions and appropriate scientific contexts of the new indices for environmental building studies, we review information theory, ecological theorems, and a few pioneering studies. Emergy and information have a great potential for advanced environmental building analysis, but building-scale implementation of emergy, information, and system principles remains a scientific challenge. The findings call for further research into the improvement of building-specific emergy/information data and reliable evidence of the analogy between building and open living systems.
