Comparative assessing prefabricated and conventional 3D morphology carbon emission intensity of economy chain hotel buildings in Hangzhou.
Article in Scientific reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Understanding the influence of building morphology on carbon emissions is essential for developing effective low-carbon strategies in the hospitality sector. This study investigates the carbon emission intensity (CEI) of 200 economy chain hotels in Hangzhou, China, constructed using comparative both prefabricated and conventional methods, from a three-dimensional morphological perspective. A comprehensive life cycle assessment (LCA) framework was adopted, encompassing material production, transportation, construction, renovation, and demolition stages. The analysis explores the relationship between 3D morphological characteristics and CEI under the two construction systems. Results indicate that prefabricated hotels generally exhibit greater carbon reduction efficiency, particularly when applied to regular geometric configurations such as rectangular and polygonal layouts. Additionally, a consistent positive correlation was found between building shape factor and CEI in both prefabricated and traditional constructions, highlighting the critical role of compact architectural form in minimizing lifecycle carbon emissions.
