“…4 In response to this challenge, an increasing number of cities and economies across the globe are reevaluating their conventional development practices and adopting energy economics principles (EEPs). 5 These principles promote energy efficiency across various aspects of urban development, ranging from building and transportation systems performance enhancements to energy conservation and the adoption of renewable energy sources. The objective is to envision a future where energyefficient, renewable, and affordable solutions drive urban development, aligned with the United Nations Sustainable Development Goals.…”

“…Consequently, ensuring the sustainability of these expanding urban landscapes requires concerted efforts in planning and implementing energy policies that not only meet the increased demand but also reduce environmental impact and contribute to the fight against climate change 4 . In response to this challenge, an increasing number of cities and economies across the globe are reevaluating their conventional development practices and adopting energy economics principles (EEPs) 5 . These principles promote energy efficiency across various aspects of urban development, ranging from building and transportation systems performance enhancements to energy conservation and the adoption of renewable energy sources.…”

“…In the context of this study, energy economics principles (EEPs) are defined as a set of guiding principles and practices aimed at promoting energy efficiency, renewable energy adoption, and sustainable energy practices within the construction industry 6 . According to Torres‐Quezada et al, 5 EEPs encompass strategies such as optimizing building design, utilizing energy‐efficient materials and technologies, implementing smart energy management systems and integrating renewable energy sources into construction projects. Despite the importance of EEPs in reducing energy consumption, minimizing environmental impact and achieving long‐term economic viability in the built environment, developing countries such as Nigeria continue to face challenges in fully adopting and implementing these practices.…”

In developing countries, there is a scarcity of research focusing on the factors that drive the adoption and utilization of energy economics principles (EEPs). EEPs encompass a diverse set of strategies and practices designed to encourage energy efficiency, promote the adoption of renewable energy sources, and foster sustainable energy practices among construction stakeholders. Despite their potential benefits, such as reducing energy consumption and greenhouse gas emissions, there remains a knowledge gap regarding the specific drivers influencing the implementation of EEPs in developing countries. Therefore, this study addresses this knowledge gap by examining the primary drivers for utilizing EEPs in the Nigerian construction industry. To achieve this objective, a quantitative research approach was adopted. Close‐ended questionnaires were developed and distributed to professionals in the construction industry, encompassing architects, builders, engineers, and quantity surveyors. The normality of the data was confirmed through univariate skewness and kurtosis analysis. Based on the relative importance index (RII) and mean scores, the highest‐ranked driver was government policies and regulations, followed by economic growth and job creation. Environmental sustainability ranked third, while energy cost savings and return on investment occupied the fourth and fifth positions respectively. Through exploratory factor analysis and fuzzy synthetic evaluation, six key criteria that drive the adoption of EEPs were identified: financial‐related drivers, environmental‐related drivers, social‐related drivers, government‐related drivers, technological‐related drivers, and behavioral‐related drivers. By identifying these six distinct clusters of drivers, this study enhances the understanding of the drivers for implementing EEPs, ultimately facilitating the transition to more energy‐efficient and sustainable practices in the construction sector and beyond.

“…In this context, with the objective of providing local information that contributes to the generation of a national database of construction materials, which currently does not exist [ 20 ], the present research proposes to quantify the embodied energy and CO 2 emissions to the environment of each stage of ready-mixed concrete production. It will allow decision makers to seek better ways to minimize their associated impacts.…”

Concrete is the most commonly construction material used worldwide. In contrast to other countries, Ecuador lacks studies that determine the environmental impact of the production of construction materials. This research presents a quantification of embodied energy and CO2 emissions associated with the concrete production, using as a case study a ready-mixed concrete plant in the city of Cuenca, Ecuador. The study was based on the Life Cycle Assessment methodology established by ISO 14040 and ISO 14044, and the 2006 Intergovernmental Panel of Experts on Climate Change (IPCC) Guidelines for National Greenhouse Gas Inventories. The production of ready-mixed concrete was considered for one year, with a “gate to gate” approach including the “transport of raw material” to the concrete plant and the subsequent “transport of final product” to the construction site. The results revealed that to produce 1 m3 of ready-mixed concrete, its production required 568.69 MJ of energy, accompanied by 42.83 kg CO2. Indirect transport generates the greatest environmental impact, especially the “transport of raw materials”, which represents approximately 80% of the embodied energy and 79% of CO2 emission.

This article presents the Specific Total Embodied Energy (STEE) and Specific Total Weight (STW) of 40 Andean residential buildings in Ecuador, from 1980 to 2020. Firstly, the BoM of ten buildings of every decade was obtained through field work carried out in three urban sectors of this city. Secondly, the specific embodied energy and specific weight of every material found in the 40 samples were obtained by bibliography. Finally, the calculation of each building was divided into three components: Structure, Envelope and Finishes. The analyzed data show a detailed collection of different materials and construction typologies used in these four decades, and the impact on their embodied energy and their weight. Moreover, this article gives a Specific Embodied Energy and Specific Weight database of 25 materials that are extensively used in Andean regions. The results show several changes in reference to the insertion of new material, but also regarding the adoption of new architectonic models. The most important changes, in the analyzed period, have been the use of concrete and metal in the structure instead of wood, the increase in the glass surface in the envelope, and the replacement of wood by particleboard on the finishes. In conclusion, the STEE of the entire building has experienced an increase of 2.19 times in the last four decades. The STW value has also increased, but to a lesser extent (1.36 times).
