We provide a summary of the progress all 53 assessed components describing global alignment with Net Zero Emissions by 2050 Scenario (NZE) International Energy Agency (IEA), an intermediate trajectory scope 2030. The (grouped in eight categories) cover sectors (such as Transport, and Buildings), subsectors Aviation, Building Envelopes), technologies Biofuels, Electrification), infrastructure cross-cutting strategies CO2 Transport Storage, Electrolyzers). For each component, IEA assigned one three qualitative levels; namely “On track”, “More efforts needed”, or “Not on track”. IEA’s assessment results were made publicly available form online web-based report, titled “Tracking Clean Progress”, TCEP, which was published 12/July/2023. Out TCEP’s components, only rated these are (1) Solar Photovoltaic (PV), (2) Electric Vehicles (EV), (3) Lighting. remaining 50 TCEP; 28 22 propose quantitative aggregate numerical score to describe overall clean energy transition reflected TCEP we compute it 2.23/4 (or 55.7%). Finally, present selected historical records (based data) about satisfactory for transition.

Silicon substrate golden light LED, as an emerging blue-light-free health lighting technology, has become one of the key technologies for home environments. This study uses silicon LED source lighting, and based on demands two indoor types, employs DIALux Evo simulation software to simulate environment. First, simulated data various areas are compared with national standards (GB/T50034-2024) verify whether type meets requirements. Next, a comparison is made between efficiency reference sample validate possesses high low power consumption. Finally, long-term exposure both used record secretion levels melatonin in human body. The experimental results show that not only provides sufficient but also demonstrates Additionally, under illumination concentration significantly increases (960 ± 15) pg/mL after 2.5 h exposure, which 8.2 times higher than conventional group (t = 12.34, df 14, p < 0.001). technology feasible solution design by creating zero-blue-light

Abstract Displays are the ubiquitous medium to convey information in modern world. The perceived quality of images seen on displays can be affected by lighting, contrast, and spatial characteristics content. While past studies investigated impact display luminance ambient illuminance preference discomfort, granular perceptual qualities, such as visual clarity, interest, complexity, have been rarely investigated. This study investigates potential use lighting image metrics develop a computational model viewers' response indoor environments shown display. In psychophysical experiment, 42 participants evaluated under different (50 cd/m 2 250 ) lx, 150 450 900 lx) conditions. Ambient had minimal implying optimal experiences achieved without resorting high or levels, thus offering energy‐saving opportunities. results also highlighted interconnectedness attributes, increased interest with clarity colorfulness. Linear regression analysis leads low predictive power, which highlights challenges developing an accurate perception.

Benchmark studies of the environmental impacts buildings often overlook contribution lighting systems. This omission presents a significant knowledge gap, especially given growing focus on energy-efficient technologies and sustainable building designs. To address this life cycle assessment method was used to calculate systems, focusing Global Warming Potential (GWP) indicator. An in-depth review databases programs across 27 European Union member states also conducted. The study analyzed both absolute relative contributions systems overall buildings, with specific situation in Denmark. A total 101 Environmental Product Declarations (EPDs) covering 753 LED products were identified. Material-related accounted for 1–12% GWP, while energy during operations contributed 6–24%. These results emphasize importance embodied operational impacts. Improving luminous efficacy emerges as more effective feasible strategy reduce building’s GWP than lowering use or grid carbon intensity. In countries high-carbon electricity, reducing is critical. Elsewhere, selecting low essential.
