“…LEED's renewable energy criterion is particularly stringent, requiring stakeholders to generate a portion of their building's annual energy consumption on-site within a 10-year period. This requirement ranges from 20% for on-site generation to 100% for offsite renewable utilization [112]. The aim of this credit is to reduce environmental and economic impacts associated with fossil fuel-based energy sources while promoting the use of renewable energy alternatives.…”

Energy accounts for a significant share of carbon emissions, and buildings play a substantial role in this by contributing to both direct and indirect emissions throughout their lifecycle. Enhancing energy efficiency in buildings is a strategy to mitigate these impacts. The main goal of this review is to uncover solutions, trends, and examples of good practices in the field of office buildings. It presents effective cases and a SWOT analysis of LEED, BREEAM, and DGNB certifications, highlighting their contributions to energy efficiency in buildings on an international scale. The paper identifies and outlines similarities and differences between each methodology used to achieve energy efficiency in different buildings and contexts. The findings may allow new ways to improve access and obtain results regarding energy efficiency, thereby supporting building owners and companies in finding more effective solutions. The research highlights the necessity for continual enhancements in these systems, which should involve addressing economic factors, conducting post-occupancy evaluations, and considering lifecycle perspectives. The recommendations encompass standardizing practices, considering costs, conducting regular revisions, managing materials and resources, and incorporating occupancy measures.

This paper presents a detailed analysis of embodied carbon (EC) in various case studies using life cycle assessment (LCA) methodology. Through comprehensive assessments, including modules A, B and C, the study evaluates EC across different stages of building life cycles. This study also considers the EC savings achievable through current end‐of‐life strategies in the UK context. As Module A accounts for the highest EC in the case studies, the majority of reduction strategies should focus on this stage. The most impactful strategy for reducing EC emissions involves incorporating Ground Granulated Blast Furnace Slag (GGBS) as a replacement for cement. This approach has the potential to achieve a substantial reduction in the EC of concrete within the buildings under investigation, ranging from 60% to 70%. The study reveals that specification strategy can lead to significant Whole Life Embodied Carbon (WLEC) reductions, with the residential building achieving a 30.59% reduction, the college building a 46.86% reduction, and the hotel building a reduction of 23.69%. Effective mitigation strategies, such as utilizing recycled and reclaimed materials, demonstrate promising results, showcasing significant reduction in WLEC emissions in the buildings.
