mus floriferus and Lotus corniculatus provided better cooling than
the larger erect species Dianthus carthusianorum and the grass
Koeleria glauca. A viable explanation may be that the low growing
spreading species shaded a greater percentage of the roof than
the upright species. Shade provided by higher leaf area index
will influence the overall albedo of the roof and decrease solar
radiation that reaches the substrate surface.
Another thermoregulation study conducted in Ontario over a
four-year period compared modules planted with sedum vs herbaceous plants and grasses (meadow). Here sedum outperformed
the meadow over the total inter-annual survey period (Sookham
et al., 2018, Ecological Engineering 123:10-18). During the
summer, mean substrate temperatures, maximum substrate
temperatures, and diurnal substrate temperature ranges were all
higher for the meadow relative to sedum. During the summer,
the meadow mixture maximum substrate temperature was 5.7
°C warmer compared to the sedum. Even when irrigated, the
meadow was still 2.4 °C warmer, but it does show the cooling effect of irrigation. Although, this study did not measure heat flux,
substrate temperature is linked to heat flux into the building
which would influence energy consumption for air conditioning.
In a study conducted in Michigan where heat flux was
