Energy Efficiency in Public Buildings: A Step toward the UN 2030 Agenda for Sustainable Development

Abstract

Within the context of the UN Sustainable Development Goals for the Agenda 2030, this article aims to explain and understand the usefulness of energy audits and their potential to reveal energy efficiency opportunities in a small public building located in northwestern Mexico. The methodological structure was adopted from the Cleaner Production–Energy Efficiency Manual published by the United Nations Program for the Environment. A case study approach was employed to examine how energy audits might potentially increase energy efficiency opportunities in the participating building. Amongst the findings, the primary source of energy wastage was occupants’ behaviors. Furthermore, this study showed that energy audits could be useful to establish a baseline in situations where previous data were not available, to allow comparisons as well as to identify opportunities in old buildings for the purpose of increasing their energy efficiency performance. As a practical implication of this research, the Sonora government can be in a better position to assist the Mexico federal government in reaching some of the country’s General Law on Climate Change objectives, particularly the one related on cutting down greenhouse gas emissions by 30% by the year 2020, and 50% by the year 2050, compared to those registered in 2000.

Improving the Energy Performance of Public Buildings in the Mediterranean Climate via a Decision Support Tool

“…Mungia et al [25] explore the role of energy efficiency in public buildings for the UN 2030 sustainable development. The authors explain how energy audits are relevant for energy efficiency in residential, commercial and public buildings.…”

The portrayal of SME leaders in Kuwait on SDG 12

“…In addition, there are many structures that help business to achieve their sustainability goals by providing action plans, as many international organisations require SMEs to have a sustainability report (Shields and Shelleman, 2015), and there are drawbacks if companies do not impose sustainability goals such as those involving waste and pollution (Geraldo Cardoso de et al ., 2022). Even the UN's SDGs have imposed energy audits to measure companies' level of efficiency (Munguia et al. , 2020).…”

Analysis of the evolution of China’s energy legal system under the background of discrete model theory and dual carbon

“…The main manifestation is that the coercive force of energy laws is not strong; specifically, the legal provisions are not detailed enough, the legal rank is low, the applicability is poor and the enforcement is not high [6,7]. To a certain extent, this has affected the development of China's energy industry, the update of energy technology, the improvement of energy efficiency, the development and utilisation of new energy, and the development of environmental protection in the energy field [8]. At the same time, it is important to take notice of the fact that there are not many domestic scholars engaged in research in this field, and the available academic literature is relatively small and unsystematic.…”
