Abstract
Improving in the energy efficiency of urban buildings, and maximizing the savings and the resulting benefits require information support from city decision-makers, planners, and designers. The selection of the appropriate analytical methods will allow them to make optimal design and location decisions. Therefore, the research problem of this article is the development of an innovative decision support system using multi-criteria analysis and Geographic Information Systems (decision support system + Geographic Information Systems = DGIS) for planning urban development. The proposed decision support system provides information to energy consumers about the location of energy efficiency improvement potential. This potential has been identified as the possibility of introducing low-energy buildings and the use of renewable energy sources. DGIS was tested in different construction areas (categories: A, B, C, D), Zielona Góra quarters. The results showed which area among the 53 quarters with a separate dominant building category was the most favorable for increasing energy efficiency, and where energy efficiency could be improved by investing in renewable energy sources, taking into account the decision-maker. The proposed DGIS system can be used by local decision-makers, allowing better action to adapt cities to climate change and to protect the environment. This approach is part of new data processing strategies to build the most favorable energy scenarios in urban areas.
Highlights
Progressing urbanization and climate change are interacting processes that require comprehensive actions to minimize their negative effects
This article analyzes the improvement of energy efficiency in urban areas, starting from individual households in buildings located in quarters characterized by similarity of structure and intensity of development
There are many possible changes and improvements, and each brings different benefits, so what is the possibility of choosing the optimal variant? It should be remembered that the programs have different recipients—building owners, users using RES, electricity producers, users of some technology or obtaining a specific consumption rate, prosumers, organizations related to environmental protection, etc
Summary
Progressing urbanization and climate change are interacting processes that require comprehensive actions to minimize their negative effects. Energy consumption in urban areas results directly from their function, the way buildings are used, and the increasing time we spend in them It results from the growing demand for services (including construction), and the need to ensure and maintain thermal comfort in buildings. An interesting solution proposed in Polish work [17] is the creation of energy cooperatives based on local communities that produce energy using renewable energy sources and use it for their own needs Such local policy increases social and environmental awareness and can improve the quality of residents’ lives
