Against this backdrop, this dissertation aimed to assess the actual state of conservation of the rendered facades of historic buildings in Lagarto, Sergipe (SE), using an integrated approach that links architectural characteristics, construction techniques, constituent materials, and pathological manifestations. Three representative examples of distinct typologies, built between the 19th and early 20th centuries around the Praça da Matriz, were selected: the Colonial Residence at No. 175 (wattle-and-daub construction); the Church of Our Lady of the Rosary (Neo-Gothic style, stone masonry); and the former City Hall (stone masonry). The methodology comprised a literature and document review, architectural analysis, laboratory characterization of mortars (visual and petrographic analysis, particle size distribution, soluble salt testing, and X-ray diffraction), visual inspection with damage mapping, infrared thermography, and the application of the Conservation Status Indicator for Historic Building Facades (IDh). The results revealed a critical state of conservation across the evaluated group and allowed for the distinction of two material families—historic air-lime mortars (in the Residence and the Church) and contemporary cement-based repairs (in the City Hall)—as well as three predominant degradation mechanisms: structural (due to settlement) in the Residence; physicochemical (due to rising damp and salinization) in the Church; and material incompatibility (due to non-conservative interventions) in the City Hall. The application of the IDh index confirmed this scenario, with values ranging from optimal (9.60% on the church's north façade) to very poor (776% at the Residence and up to 243% at City Hall), demonstrating that the most severe degradation is systematically associated with the replacement of original materials with rigid, impermeable cement-based mortars. It is concluded that an integrated technical diagnosis not only quantifies degradation but also identifies its root causes, providing a scientific basis for compatible interventions that respect the authenticity and integrity of Lagarto’s built heritage and inform future municipal preservation policies.

In this context, the evaluation of lighting systems must reconcile energy consumption and the luminous quality of interior spaces. This research aims to evaluate the electric lighting system of the Epiphanio Dória Public Library (BPED), in Aracaju-SE, Brazil, according to the Simplified Method of the Inmetro Normative Instruction for the Energy Efficiency Classification of Commercial, Service, and Public Buildings (INI-C) and the Brazilian standard ABNT NBR ISO/CIE 8995-1, to verify the possibility of achieving Class A, and to propose improvements in energy and luminous performance. The research was developed in five stages: bibliographic and documentary review; architectural and lighting system survey; energy assessment according to INI-C; luminous performance assessment according to ABNT NBR ISO/CIE 8995-1; and proposition of an optimized scenario. The current scenario, although it reduces consumption by 86.7% compared to the reference condition, does not meet the INI-C lighting control eligibility criteria and remains classified as Class B. The proposed scenario (79.4% reduction) meets these criteria through independent circuits per room, achieves Class A, and increases compliance with ABNT NBR ISO/CIE 8995- 1 from 4.4% to 97.1% of the assessed rooms. It is concluded that the modernization is technically feasible and depends on the renewal of light sources, the redistribution of luminaires, and control strategies integrated with daylight.

In this context, the preservation of the built environment is understood as a sustainable practice, as it contributes to reducing demolitions and the demand for new resources, extending the service life of the building stock, and valuing the material and construction resources incorporated into buildings. When the built environment has historical and cultural significance, its preservation is not limited to the building’s physical permanence but involves the continuity of historical, symbolic, and social values that underpin its recognition as heritage. This dissertation analyzes the intervention at Casa de Cultura Silvio Romero, the only listed heritage property in Lagarto, Sergipe, Brazil, considering built environment preservation as a sustainable practice and the relationship between adaptation to use, material and construction solutions, and the preservation of heritage values. The qualitative, exploratory, and descriptive research emphasized a case study. Methods included a bibliographic and documentary review, analysis of the executive design and descriptive memorial, technical visits, photographic records, and comparison between the design and completed work. The analysis demonstrated that the intervention is sustainable by recovering an abandoned historic building and restoring it to usable conditions within the urban context. However, comparison between design and execution revealed different levels of adequacy among the elements examined regarding the quality of the intervention, which may compromise the building’s material integrity, historical legibility, historical values, and long-term conservation. The window and door frames, metal fittings, and wooden flooring were considered adequate; the façade, roof, and contemporary additions were considered partially adequate; whereas the wooden ceiling and the use of cement-based plaster on the internal masonry walls revealed inadequacies. A change from the intended cultural use to a public administrative function was also observed. Therefore, the intervention demonstrates that the preservation of the built environment as a sustainable practice is not limited to the physical recovery of the building but requires the integration of the quality of design decisions, the effectiveness of execution, and the coherence of its use, which are fundamental conditions for ensuring its long-term conservation.

In this context, the use of beneficial microorganisms for seed treatment represents a promising strategy to directly influence germination, vigor, and early plant establishment. This thesis integrates studies on bio-inputs, bacteria, osmoprotective solutions, the isolation and characterization of the biotechnological potential of mixed microbial cultures, and the induction of systemic resistance, with an emphasis on utilizing microbial resources and developing technologies applicable to regional agricultural conditions. Chapter 1 details the development of a technological solution for treating stored soybean seeds, combining microorganisms with an osmoprotective matrix to improve seedling vigor. Various imbibition periods and microbial treatments were tested, revealing that the response depends on the formulation's composition and application conditions. The treatment promoted early growth characteristics and vigor in soybean seedlings, highlighting the potential for developing formulations for biological seed treatment. Chapter 2 evaluates the biopriming of maize seeds with Bacillus amyloliquefaciens, assessing germination, seedling morphology, and the activity of antioxidant enzymes— specifically superoxide dismutase, ascorbate peroxidase, and catalase. While germination rates remained unchanged, exposure time proved crucial for seedling vigor, growth, and antioxidant metabolism. A four-hour exposure yielded positive responses, whereas six hours of exposure was associated with reduced vigor and increased ascorbate peroxidase activity, reflecting a higher antioxidant demand. These chapters demonstrate that contact time is a decisive variable; appropriate durations foster balanced physiological responses, whereas prolonged exposure can alter metabolism and compromise vigor. In Chapter 3, mixed microbial cultures were screened, and their biotechnological potential was evaluated regarding inorganic phosphorus solubilization, *in vitro* antagonism against the fungus Macrophomina phaseolina, and germination in bean and soybean crops. In Chapter 4, a systematic review gathered evidence on systemic resistance induced by beneficial microorganisms. Trichoderma, Bacillus, and Pseudomonas stood out as key genera involved in activating plant defenses, a process mediated by genes, proteins, enzymes, reactive oxygen species, and hormonal pathways linked to jasmonic acid, salicylic acid, and ethylene. Collectively, these studies provide insights into the efficiency of bio-inputs and highlight how performance depends on the interplay between the microorganism, formulation, plant species, application timing, and environmental conditions. Overall, the results reinforce the potential of the evaluated bio-inputs but also demonstrate the need for further research into stability, compatibility, microbial survival, and agronomic validation across different production conditions.
