Evaluating the Effects of Façade Greening on Human Bioclimate in a Complex Urban Environment

Table 4

Sum (00–23 CET) of long- and short-wave radiation at the greened and the bare site up- and downward (up, down) and from the cardinal points (west-northwest (WNW), east-southeast (ESE), south-southwest (SSW), and north-northwest (NNE) (direction from the façades)) on 7, 23, 2013. is the angular factor used in calculation of mean radiant temperature (0.06 for up- and downward radiation and 0.22 for radiation from the cardinal points).
