Effect of Ventilation Strategies of Center-Mounted Louver Ventilation Window on Building Energy Consumption and Daylighting

Sustainability, Journal Year: 2025, Volume and Issue: 17(2), P. 670 - 670

Published: Jan. 16, 2025

An innovative center-mounted louver ventilation window suitable for seasonal strategies was proposed, combining the regional climate of Qingdao. The sustainable development concept is embodied, which can not only reduce building energy consumption but also consider quality daylighting. This research constructed a comprehensive evaluation framework, taking an office in Qingdao as example. framework utilized parametric design platform Grasshopper and its environmental plug-in Ladybugtools. It considered daylighting performance building. study included six different strategies, with use intensity useful daylight illuminance indicators. results indicated that parameters blinds were optimized to significantly improve efficiency without compromising quality. solution reduces from 83.81 kWh/m2 55.0 kWh/m2, achieving 34.4% reduction while maintaining high UDI. energy-saving effect reveals influence on And it provides important reference similar contexts.

Bridging the Gap to Decarbonization: Evaluating Energy Renovation Performance and Compliance

Energies, Journal Year: 2025, Volume and Issue: 18(5), P. 1146 - 1146

Published: Feb. 26, 2025

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