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.

This paper concerns measurements and CFD simulations of vacuum-insulated glazing (VIG), which consists of two glass panes separated by a narrow gap from which air has been removed. Distancers, e.g., in the form of small balls, are inserted into this gap every few centimeters to prevent the glass from deflecting. In the first part, simulations of two-pane VIG thermal transmittance with the Ansys Fluent program are described, resulting in thermal transmittance of VIG without the network of distancers equal to 2.18 W/(m2K) and with the distancers equal to 2.29 W/(m2K). The influence of the supports on the thermal transmittance of VIG is also determined. The CFD results show that the supporting balls increase the two-pane VIG thermal transmittance by about 0.15% with respect to the glazing without the distancers. Then, VIG is analyzed both numerically and tested in two measurement stands. Firstly, the tests are performed in a guarded hot-plate apparatus, according to the EN ISO 8302 standard. The two-pane glazing with one low-emissivity coating has a measured thermal transmittance equal to 1.75 W/(m2K). Other measurements were undertaken in the calorimetric chamber equipped with the hot-box apparatus. The results of the numerical assessment are then compared to the measurements of the existing three-pane vacuum-insulated glazing with two low-emissivity coatings, the same as simulated. The procedure follows the EN ISO 8990 standard. Measurement results of 1.10 W/(m2K) are compared to the simulation results of VIG thermal transmittance equal to 1.09 W/(m2K). A satisfactory agreement is reached. Additionally, this paper considers a new correction coefficient to thermal transmittance according to standard EN 673 in order to achieve a proper calculation of vacuum-insulated glazing in the center-of-glass region. The authors propose to use an adjustment coefficient of 1.05 when calculating the thermal transmittance of vacuum-insulated glazing without taking into account convection in the vacuum space and the thermal influence of distancers.

The urban public lighting system plays a fundamental role in enhancing safety and shaping the nocturnal identity of the city. Efficient lighting is also a key factor in reducing energy consumption and lowering atmospheric emissions. In the context of sustainable development goals, increasing attention is being directed towards the energy, social, economic, and environmental benefits associated with the adoption of LED lighting systems. This paper aims to assess the environmental impacts of two different public outdoor lighting replacement planning scenarios. The methodology employed in this study calculates the environmental impacts using a life cycle approach, incorporating data from the Environmental Product Declarations (EPDs) of the lighting systems. It involves a systematic census and categorization of lighting fixtures based on their installation year to determine both their quantity and average efficiency. This methodology, applied to a case study, demonstrates that it is possible to reduce the CO2-equivalent emissions by approximately 7% depending on the technical and environmental performance of the fixtures and the timing of their replacements. These results provide a scientific foundation for supporting both the preparation of planning tools by governance entities and the technical and economic feasibility of designing and implementing interventions aimed at improving the environmental performance of public lighting. These efforts could contribute to achieving climate neutrality, conserving biodiversity, and mitigating the effects of climate change. Full article
