Solar Energy Potential Mapping around Yogyakarta Palace As an Effort in Integrating Renewable Energy into Cultural Based Economic Development

Abstract

The Yogyakarta Palace is the main heritage buildings in Yogyakarta Province. It is a main cultural symbol, which is also one of the main tourism objects. This research focuses on The Palace main buildings and surrounding area as an effort to integrate acceleration of renewable energy use into the cultural-based economic development. It considers cross-cutting issues in integrating engineering approach within a complex socio-culture context. The research applied distribution of solar energy potential mapping by using analysis of 3D buildings data in the Open Street Map (OSM), Digital Elevation Model (DEM) and solar intensity data. QGIS software was applied to analyze the 3D buildings data and geospatial aspect. The research also provides a classification of solar energy potential. The mapping shows valuable capacity of The Palace and its surrounding area to produce electricity by the PV technology. Implementing, for instance, the Building Integrated Photovoltaics (BIPV) method in selected buildings, could provide encouraging environment for green tourism in a city of culture melting point as well as increase of renewable energy role and economic development. However, in such delicate issue of PV implementation the mapping and installation works would be far simpler tasks compared to the required intensive socio-culture inclusive process.
