Fig. 3: Comparison of floor plans from Zurich, New York, and Singapore.
From: A hypergraph model shows the carbon reduction potential of effective space use in housing
A principal component analysis (PCA) of the hypergraphs of all floor plans (see “Methods” Residential floor plan dataset) shows a unique graph structure of each city (a). The calibrated dataset is analyzed to evaluate spatial daylight autonomy (sDA) (b). Carbon saving scenarios through excess area reduction and envelope upgrades are compared and show that in Zurich, 71.6% of apartments would save more carbon through reducing excess area, compared with 61.0% in New York and 33.0% in Singapore (c) (see “Methods”, Excess area and emissions).
