Additionally, the growing demand for cloud-based services and large-scale applications has further increased this workload. In this context, a case study was conducted in the local Data Center, focusing on improving energy efficiency, ensuring service continuity, and preventing potential equipment failures. Beyond the challenges related to the quality and continuity of electrical power supply, which directly affect DC operations, each technological expansion at the university requires investments in new equipment and leads to higher energy demand. Within this scenario, the present study proposes an analysis of the UFMS DC infrastructure aimed at optimizing energy efficiency, reducing electrical consumption, and identifying alternatives to improve the thermal conditions of the environment. To achieve this, a multidisciplinary approach was adopted, employing quantitative methods to examine the DC’s operational conditions. This includes the characterization of ideal DC environmental models, the definition of essential information needed to ensure continuous equipment operation, and an integrated analysis of the operational, thermal, and structural conditions of the environment. The research was conducted in stages, including the survey of equipment power demand, on-site visits and checklist application, temperature measurements and monitoring, analysis of electrical and thermal demand, and simulation using the CFD CoolSim software. As a result, the study not only quantified the energy consumption of the environment but also verified that, for the most part, the DC presents thermal conditions consistent with ASHRAE recommendations. Additionally, improvement proposals were presented based on the existing infrastructure, with the aim of fully meeting the technical standards of the sector and strengthening practices aligned with energy efficiency and sustainability in DC.

Among large-scale public housing policy solutions, housing improvement programs emerge as a strategic approach. Nevertheless, the implementation of such initiatives faces significant challenges, particularly with regard to scalability. In response to the need for greater efficiency and productivity, this study seeks to analyze housing improvement initiatives that may contribute to the development of more effective and successful implementation processes. This qualitative research is based on a literature review and a case study. The literature review examines housing improvement actions and Technical Assistance for Social Housing (ATHIS), drawing on an analysis of completed experiences to identify strategies adopted to address implementation challenges, including local specificities, stakeholder diversity, and diverse institutional arrangements. The case study applies the analytical framework derived from the literature review. The findings highlight strengths and weaknesses and demonstrate that the framework can support both pre-implementation and post-implementation phases. Moreover, the framework is not restricted to housing improvement projects and may be applied to any social housing project or program involving ATHIS. Synthesis tables were developed to classify projects and their respective strategies, serving as a benchmarking tool. It is expected that future housing improvement research and initiatives may benefit from this framework to assess their specific contexts and to design tailored structures and workflows, acknowledging that the diversity of variables involved precludes the establishment of a single standardized procedure.

This study analyzes the sizing of the vent area for explosion pressure relief and mitigation in vertical silos, in accordance with standards NFPA 68:2023, EN 14491:2012 and NBR 16385:2015, and presents the development of the V-Calc software, created in C# for calculating the relief area according to each methodology. Silos with different H/D ratios and variations of P_(red ) were evaluated. The results showed that NFPA 68:2023 maintains constant areas for H/D ≤ 2.0, whereas EN 14491:2012 yields higher values in all cases due to the minimum limit of P_stat≥0,1 bar, evidencing a more conservative approach. The V-Calc software proved effective for the analysis and design of pressure relief systems, contributing to safer, more resilient, and sustainable projects, in line with the Sustainable Development Goals.

This work proposes and validates an integrated and replicable model for the elimination of landfills in medium sized cities, using Campo Grande-MS as a case study. The model synergistically combines a slow pyrolytic carbonization plant with high-value-added recycling production chains, positioning itself at the forefront of the circular economy applied to urban management. The approach transcends conventional "end-of-pipe" solutions. This process converts the residual fraction of MSW (~161 t/day) into a portfolio of market-value products: biochar, pyrolytic oil, and syngas. Beyond the drastic reduction in volume and emissions, the model generates a surplus of ~2.2 MW of electrical energy and enables carbon sequestration through the stable application of biochar to the soil. Simultaneously, recyclable fractions are directed to local production chains that transform them into inputs for the construction industry, such as ecological bricks, plastic roof tiles, paving elements, and urban furniture, closing the materials loop. The adopted methodology combined critical bibliographic research, detailed technical modeling with mass and energy balances, and economic-financial analysis via discounted cash flow. The modeling demonstrates that the integrated system is capable of diverting between 684 and 791 tons of waste per day from the landfill, exceeding the total waste generation of Campo Grande and achieving the "zero landfill" goal. The honest and well-founded economic analysis reveals that the financial viability of the investment (estimated CAPEX of R$ 200-250 million) is intrinsically linked to the internalization of environmental benefits. While a scenario without support mechanisms presents a negative NPV, the introduction of a landfill diversion fee ("gate fee"), a consolidated practice in Public-Private Partnerships, makes the project economically attractive, with a positive NPV of R$ 40.1 million in the base scenario. It is concluded that the transition to a circular and sustainable model is technically and economically feasible.
