ABSTRACT:
Sustainability assessment of the building located in Athens known as “ESTIA of Athens” has been performed. Although, the building underwent through the process of renovations between 2005-2006 and 2020 that include upgrades to heating, hot water systems and Wi-Fi installation, the high energy consumption remained. As a result, a Buildings Management System was introduced to monitor indoor conditions, external factors and energy usage.The historical data from 2018 to 2022 together with simulated renovation and hypothetical scenarios were used to conduct Life Cycle Assessment. Two main renovation scenarios include: (i) the “diagnosis” scenario, focusing on lighting replacement, interior redecoration and maintenance, and (ii) “optimization” scenario, integrating external blinds, rooftop PV panels and basement ceiling insulation. Hypothetical simulations conducted on six rooms assessed the impact of various factors such as window status, mechanical ventilation, cooling and heating on energy consumption. Although, it was limited to these rooms, the results were extrapolated to estimate the energy consumption for the entire building. Additionally, FusiX sensor data for electricity consumption from December 2022 to August 2023 were used. The comparative analyses showed significant variations in energy consumption and environmental impact across the different scenarios. The scenarios with heating and cooling optimizations demonstrated reduced energy consumption and improved environmental impact while scenarios with mechanical ventilation demonstrated higher electricity consumption and environmental impact. The findings emphasize the importance of implementing energy-efficient technologies to mitigate environmental impact while ensuring resident comfort. Future strategies should prioritize minimizing electricity consumption through optimized heating and cooling systems while promoting sustainability in residential buildings.
