Figure 5
Each diagram has four vertical columns, from left to right: Multivariate issue, Location, Methodological choice, and Solution. Colored bands flow from the left column to the right, with the width of the band indicating the number of papers for that theme combination. Numbers in parentheses next to each item indicate the count of papers. a. Period 2009 to 2013: Multivariate issue: It shows two groups: M C plus I T C (5 papers) in light blue. M C plus I T C plus Da (2 papers) in red. Location: It shows three groups: U H I (3 papers) in blue, L M I (1 paper), and U M I (3 papers) in orange. Methodological choice: It shows four groups: F m plus Su (2 papers) in purple, F m (1 paper), Si (2 papers) in pink, R v (1 paper), and Si plus F m (1 paper). Solution: It shows two groups: Building level (5 papers) in light blue, Site and Building level (1 paper) in blue, and Site level (1 paper) in blue. b. Period 2014 to 2018 Multivariate issue: It shows two groups: M C plus I T C (11 papers) in light blue and I T C plus Da (2 papers) in red. Location: It shows three groups: U H I (7 papers) in blue, U M I (3 papers) in orange, and L M I (3 papers) in green. Methodological choice: It shows four groups: F m plus S u (3 papers) in purple, F m (1 paper), Si (7 papers) in pink, and Si plus Fm (2 papers). Solution: It shows three groups: Building level (7 papers) in yellow, Site and Building level (2 papers) in light blue, and Site level (4 papers) in light blue. c. Period 2019 to 2023 Multivariate issue: It shows three groups: M C plus I T C (21 papers) in light blue, I T C plus Da (5 papers) in red, and M C plus I T C plus Da (3 papers) in purple. Location: It shows three groups: U H I (13 papers) in blue, U M I (8 papers) in orange, and L M I (8 papers) in green. Methodological choice: It shows five groups: F m plus S u (1 paper), S u (2 papers), F m (2 papers), Si (18 papers) in gray, Si plus F m (5 papers), and Si plus F m plus S u (1 paper). Solution: It shows three groups: Research (3 papers) in orange, Building level (19 papers) in green, Site and Building level (5 papers) in red, and Site level (2 papers) in red.Sankey diagram on distribution of themes over time.
