Eco-Efficient Ventilated Facades Based on Circular Economy for Residential Buildings as an Improvement of Energy Conditions

In a planet with limited resources, climate change is severe problem, intensified by industrial development. This particularly important in the construction sector. According to International Energy Agency (2021), sector responsible for 40% of global energy consumption and 36% CO2 emissions. this way, sustainable architectural solutions should be priority our fight against change, it necessary propose that help reuse existing thus reducing consumption. sense, rehabilitation buildings favor circular economy will become key element work provides design facade building based on paradigm, which implanted model as case study. The HULC tool quantifies improvement efficiency entails when compared conventional facade. With designed facade, reduction losses through envelope achieved, well an living conditions environmental impact. Next, analysis building’s emissions carried out Open BIM Quantities tool. used researchers professionals. Finally, results show improvements
