All-optical seasonal energy saving windows.
Article in iScience, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Adaptive thermal regulation is crucial for year-round energy savings in buildings, especially in mid-latitude regions. Here, leveraging the seasonally varying angles of direct sunlight, we report a microprism-array sheet that enables seasonal energy saving windows. Guided by geometric optics, the asymmetric microprism-array sheet, featuring a silver coating on the sky-facing facets, exhibited an average transmittance of 10% in summer and 53% in winter at predominant sunlight angles, compared to 30% and 38% of a standard tint film, respectively. During outdoor testing in South Korea (37°N), a south-facing window integrated with the microprism-array sheet reduced floor temperatures by up to 5°C during direct sunlight hours, relative to a tinted window. Notably, in east-facing windows, the microprism-array sheet transitioned from heating to cooling around 9:00 a.m., highlighting its potential for modulating seasonal thermal management.
