“…Having a better representation of building geometry is necessary in identifying where a solar panel could be installed (Martin, et al, 2015). since solar panels could both be installed on the roofs and the walls of a building, (Wegertseder, et al, 2016) since walls are larger in area than roofs and may also contribute to energy production (Jaugsch, et al, 2016). Indicating the Level of Detail of a generated building model is also important to determine the accuracy of solar radiation estimates, since complex geometries like the shape of roofs and wall extrusions are taken into account (Agugiaro, et al, 2011).…”

Abstract. For the past few years the United Nations have been standing strong in advocating the 17 sustainable development goals. One of those goals focuses on affordable and clean energy, which includes renewable energy. This study focuses on the application of geomatics on renewable energy, more specifically solar energy. The research aims to determine the photovoltaic potential of Quezon City Hall in the Philippines by calculating the amount of direct solar radiation it receives through a process that uses only openly sourced 3D GIS (Geographic Information Systems). The methodology mainly consists of (1) generating a building model composed of points that contains heights derived from a LiDAR (Light Detection and Ranging) based NDSM (Normalized Digital Surface Model) through the combined use of Python and QGIS, (2) determining the intersections between the building model and the sun’s light rays, incorporating shadow factors and integrating solar irradiation values using Python, and (3) visualizing and gridding for analysis through the combined use of Blender, QGIS and a Spreadsheet software. Results have shown that Quezon City Hall has good photovoltaic potential since: solar irradiation values in 2017 has shown that the city hall receives 800 W/m2 to 1000 W/m2 on average from 08:00 to 16:00, and all faces of the building receive solar radiation. This means that all sides of the building can be proper candidates for solar panel or for Building Integrated Photovoltaics (BIPV) installations.

“…Zalamea [99] shows that roof area availability and architectural features of dwellings are determinants, so that in the same locality, it is feasible to take full advantage of irradiation, reaching a catchment that exceeds 100% of the demand if there is a surface without obstacles, compared to 10% if the roof is irregular and divided. However, in the same context, because of system restrictions of the existing grid and seasonal fluctuations, only between 15% and 27% could be covered [100].…”

The Role of Renewable Energy in the Promotion of Circular Urban Metabolism

Cities are human creations requiring large amounts of materials and energy. Constant consumption of resources exerts pressure on the environment not only due to its exploitation, but also because once processed, the resources produce waste, emissions or effluents. Cities are responsible for more than three quarters of the emissions of greenhouse gases. It is anticipated that the urban population will increase by up to 80% by the mid-21st century, which will make the current energy model unsustainable, as it is based on the intensive use of fossil resources. A change in urban planning is required to meet the energy requirements of cities. Several studies mention that renewable energy must be used in cities, but they do not identify the resources and technologies that can be used to promote circular urban metabolism. A review of the literature establishes that there are eleven renewable technologies with different degrees of maturity that could reduce the import of energy resources, which would contribute to changing the metabolic linear model into a circular model. However, the applicability of the different possibilities is conditional upon the availability of resources, costs, policies and community acceptance.

“…The first main challenge is the competition for the use of areas and/or land. For PV, solar thermal, and other uses on buildings, this aspect has already been done, for example, by Wegertseder et al., but not in a straightforward way, because it involves implicit assumptions on the respective preferences of the different technologies, which may at least partly depend on the building use and its occupants . The situation is similar for wind studies: if the issue of land competition is to be considered, this implies a judgment about the relative importance of specific land use categories for different end uses.…”

“…The second main challenge is to consider integration of the determined PV potentials into the energy system. Although this has already been done by some PV studies, for example, by Mainzer et al., Killinger et al., Srećković et al., and Wegertseder et al., these aspects are typically not considered by wind potential studies. So there is definitely scope to improve these methods, for example, by using real network topology and load flow data and/or also modeling other end‐use sectors.…”

Structural changes in the energy sector have created considerable challenges for regulators, energy consumers, and suppliers. Energy researchers rely on quantitative modeling approaches to address these challenges. At the Karlsruhe Institute of Technology, we have developed several models to analyze today's and the future's energy markets to address the challenges for electricity networks as a result of intermittent renewable and decentralized power and heat supply and to find solutions for integrating demand response. This paper presents a survey of these approaches and discusses further challenges. The developed models have proved to be suitable for answering a range of research questions related to structural changes. As the energy sector remains in a constant state of flux, these models need to be further developed. This means coupling different energy sectors and markets and improving their technical accuracy as well as their spatial and temporal resolutions.
