| description | Achieving a decarbonized built environment by 2050 requires significant advancements in building renovation strategies, with a strong emphasis on energy efficiency and emissions reduction. This study examined the compliance of buildings renovated between 2015 and 2022 with national energy performance regulations. While many buildings have undergone improvements, a substantial portion still fail to meet the stricter, current requirements, particularly in terms of window and floor insulation, highlighting the need for further retrofit measures. Comparing static and dynamic simulation models reveals that static models frequently overestimate energy savings, leading to misaligned investment decisions. Dynamic simulations, by incorporating real-time climate interactions and transient thermal behaviors, provide a more accurate assessment of energy demand and efficiency improvements. A financial analysis indicates that static models often predict unrealistically short payback periods, potentially resulting in suboptimal renovation investments. To meet decarbonization goals, future strategies must integrate advanced simulation methodologies, strengthen regulatory oversight, and enhance financial incentives for comprehensive energy renovations. A data-driven approach is essential to ensure that building retrofits achieve meaningful energy savings and contribute to climate neutrality. Strengthening compliance frameworks and promoting standardized renovation practices will be key to bridging the gap between expected and actual performance, ensuring a sustainable and resilient built environment. |
