By showing the solar irradiation of the building rooftops, the Hong Kong Solar Irradiation Map (the Map) enables users to perform a preliminary assessment of the solar energy potential for their building rooftops.
Rooftop solar radiation maps help identify building rooftop areas that have potential for collecting solar energy by installed solar panels. Considering the solar radiation value and the appropriate tilt angle of the solar panel greatly increases the power generation capacity of the solar panel [21] and [22] .
The building sector accounts for 40% of primary energy use worldwide, 1 of which 50% is consumed to maintain desired indoor temperature by removing building thermal loads. 2 Regulation of solar and thermal radiation of building rooftop shows great promise to reduce building thermal loads for energy savings. 3, 4, 5 In principle, to …

Understanding Solar Irradiance: Measurement, Calculation ...
Contrarily to solar radiation on façades [19], [20], [21], the analysed density–related parameters do not show a meaningful relationship towards solar radiation conditions. On the other hand, as it has been presented for the four downtown municipalities, the density is a meaningful measure of the impact level of urban morphology on shading …
