SUMMARY:

The search for reducing energy impacts associated with the building's life cycle appears to be an effective tool. The energy efficiency of buildings is an increasingly recurring topic, and knowledge of design methods and assessment of the efficiency and environmental quality of buildings is essential. The study uses computer simulation and life cycle analysis tools, using consumption data in the operational phase of a building located in Goiânia-GO. The objective of this work is to evaluate the energy efficiency requirements and operational characteristics for the institutional building typology. The energy consumption indicator in the operational phase of a building was presented. In the computer simulation, we sought to improve energy consumption through strategies obtained in the literature. From the computational analyzes carried out, it is concluded that the estimated annual energy consumption of 5,231,516.97 kWh for the standard model (CEZ 0); in scenario 1 (CEZ 1), the annual energy consumption estimated by computer simulation was 5,143,237.74 kWh; in scenario 2 (CEZ 2) the annual energy consumption estimated by computer simulation was 5,134,263.25 kWh; and in scenario 3 (CEZ 3) the annual consumption estimated by computer simulation was 5,149,638.35 kWh. Scenario 2 (CEZ 2), which presented the best performance, uses double-glazed windows made up of 6 mm glass of medium thermal transmission with argon filling, external coating with acrylic polyurethane (reflectivity 0.89), external wall with thermal insulation of 0.6 cm Polyurethane foam and increased thermal mass with PCM 28 on the internal wall. The total emissions from phase A1-A3 were 1,260,295.98 kgCO2-eq for the foundation, 5,663,961.15 for the structure, 267,839.19 for the envelope, 770,914.23 for the internal partitions kgCO2-eq and 2,106,759.76 kgCO2-eq for the internal finishes, with the concrete item of the building structure being the largest emitter, with around 2.9 million kgCO2-eq, corresponding to 29% of emissions in the pre-use phase of the building, excluding transport energy. Total life cycle energy based on usage phase data, operational energy was 1,363,402.57 kgCO2-eq.
