“…In addition, methods for the calculation of short-wave radiation flux densities also exist. These techniques apply both simple and complex models with different time resolutions on the basis of different existing calculation methods (Valko 1966;Brühl and Zdunkowski 1983;Jessel 1983;Olseth and Skartveit 1993;VDI 1994;Badescu 1997;Ceballos and de Moura 1997;Meek 1997;Gul et al 1998;Mora-Lopez and Sidrach-deCardona 1998;Kemmoku et al 1999;Marki and Antonic 1999;Roderick 1999;Santamouris et al 1999;Craggs et al 2000;Gueymard 2000). Models using sunshine duration for the calculation of short-wave radiation flux densities are used (Valko 1966;Gopinathan 1992;Revfeim 1997;Sen 1998) as well as simple parameterisations for turbidity (Kasten 1980;Power 2001).…”

Urban planners are increasingly paying more attention to the topic of UHI. Within the framework of the EU-UHI Project, an industrial area inside the municipality of Modena was selected as a pilot-area for the Emilia-Romagna Region. In this paper we present some results obtained with RayMan, a model which estimates bioclimatic discomfort based on the human radiative budget. Some simulations of the impact of mitigation measures have been carried out, taking into account the insertion of greenery and building modifications. Both intra-diurnal and whole day effects have been compared.

Solar energy, as a clean and renewable resource is becoming increasingly important in the global context of climate change and energy crisis. Utilization of solar energy in urban areas is of great importance in urban energy planning, environmental conservation, and sustainable development. However, available spaces for solar panel installation in cities are quite limited except for building roofs. Furthermore, complex urban 3D morphology greatly affects sunlit patterns on building roofs, especially in downtown areas, which makes the determination of roof solar energy potential a challenging task. The object of this study is to estimate the solar radiation on building roofs in an urban area in Shanghai, China, and select suitable spaces for installing solar panels that can effectively utilize solar energy. A Graphic Processing Unit (GPU)-based solar radiation model named SHORTWAVE-C simulating direct and non-direct solar radiation intensity was developed by adding the capability of considering cloud influence into the previous SHORTWAVE model. Airborne Light Detection and Ranging (LiDAR) data was used as the input of the SHORTWAVE-C model and to investigate the morphological characteristics of the study area. The results show that the SHORTWAVE-C model can accurately estimate the solar radiation intensity in a complex urban environment under cloudy conditions, and the GPU acceleration method can reduce the computation time by up to 46%. Two sites with different building densities and rooftop structures were selected to illustrate the influence of urban morphology on the solar radiation and solar illumination duration. Based on the findings, an object-based method was implemented to identify suitable places for rooftop solar panel installation that can fully utilize the solar energy potential. Our study provides useful strategic guidelines for the selection and assessment of roof solar energy potential for urban energy planning.
