Objective: The objective of this study is to investigate the potential application of sustainable construction principles in the design and construction phases of a high-standard residential condominium, with the aim of proposing improvements that enhance its environmental, social, and economic feasibility, promoting the reduction of environmental impacts and strengthening sustainability in the construction sector. Theoretical Framework: This section presents the main concepts and theories that underpin the research. Notable among them are the principles of sustainable construction defined by Kibert (2020), such as reducing resource consumption, reusing materials, using renewable sources, protecting nature, eliminating toxic components, applying life cycle cost analysis, and focusing on quality. Additionally, the guidelines of Agenda 21 applied to the construction sector (Motta, 2009) and the assessment model based on the three dimensions of sustainability- environmental, social, and economic-are also considered. Method: The methodology adopted for this research comprises a qualitative case study focused on assessing the environmental sustainability of a residential project located in Canoas (RS), still in the pre-construction phase. The architectural, plumbing, electrical, and earthworks projects were analyzed, along with the descriptive memorial and site inspections. Data collection was carried out through the application of a checklist developed based on the principles of sustainable construction, considering aspects such as energy efficiency, use of sustainable materials, water and waste management, and environmental and economic impacts. Results and Discussion: The results revealed that the original project design presents several shortcomings in relation to sustainability criteria. Identified gaps include the absence of erosion control strategies, reliance on nonrenewable energy sources, lack of individual water metering, and lack of specifications regarding the origin of construction materials. In the discussion, these results were contextualized based on the theoretical framework, highlighting the need for reformulating sustainable practices and guidelines in the sector. Limitations such as the project's early development stage and the lack of mandatory sustainability policies were also considered. Research Implications: The practical and theoretical implications of this research are discussed, providing insights into how the results may be applied or influence practices in the field of sustainable construction. These implications may encompass the development of public policies, financial incentives for sustainable projects, training of construction professionals, and restructuring of project design and urban planning guidelines. Originality/Value: This study contributes to the literature by demonstrating, through a concrete case study, how environmental sustainability criteria can be applied during the pre-construction phase, even in projects that did not initially include them. The originality lies in the practical approach using a customized checklist for assessment and improvement proposals. The relevance and value of this research are evidenced by its potential to guide future developments toward sustainable practices and by showcasing the economic, environmental, and social benefits of such an approach.
