ANÁLISIS DEL CONSUMO DE AGUA Y ENERGÍA DE UNA EDIFICACIÓN RESIDENCIAL VERTICAL SOSTENIBLE EN LA AMAZONÍA

In the face of the global need to reduce resource consumption, environmental certifications emerge as a possibility for efficiency gains in the construction industry. This study aimed to assess the energy and water efficiency of a vertical multifamily green residential building located in Belém, in the Brazilian Amazon. The energy and water consumption data of two similar buildings were compared, with only one implementing mandatory green practices and technologies for Leadership in Energy and Environmental Design (LEED) Envelope and Core certification. As a result, water consumption was 30.64% higher than estimated. On the other hand, electricity consumption was 24.6% below the estimated project and 1.73% below the per capita consumption obtained for the building constructed without any green practices or technologies. These results demonstrate that the adopted green technologies were able to improve the energy efficiency of the studied building. However, they had low water efficiency, attributed to user behavior patterns and the LEED's inability to meet the region's water requirements. To address this issue, changes to certification criteria are suggested.
