“…Based on GIS analysis and (Geo Da) techniques as followed in LCA assist in communicating information with stakeholders (i.e., environmental organizations, communities, interested and affected parties, and authorities). The integration of GIS in LCA tool is capable to localize impact sources to organize spatial data especially at large scale; develop spatial inventory models and visualize results for stakeholders [15].…”

Background: The energy sector plays an important role in the economic growth in Jordan due to the fact that Jordan imports around 97% of its needs from primary energy. The purpose of this study is to explore the pattern of electricity consumption and energy loss to highlight the strengths and weakness of energy efficiency in the context of the urban sustainability of Amman City in Jordan. Methods: The design of sustainable urban development is based on the urban interdependencies approach, which incorporates the stakeholders to identify and pursue synergies between multiple sectors. This approach includes the identification of the functional sectors, which are related to institutional and behavioral levels in the society, raising the level of institutional performance and improving the quality of urban services. The spatial statistical analysis approach and GIS applied to analyze the consumption pattern of electrical power in the study area. Results and conclusion: There was a considerable increase in the peak domestic consumption, as the peak load reached 3320 MW in 2017 with an annual increment rate of 4.9%. Regarding energy efficiency, the value of total electrical energy losses reached 13% in 2017; around 90% of this loss occurred in the electrical distribution stage. Geographical distribution of the household electrical power shows that the east and middle parts of Amman have low consumption levels compared to the west residential parts. The energy consumption pattern has an inverse relation with the population distribution, family size, and building characteristics in the city. This is clearly identified by addressing the downtown region that has the lowest energy consumption and the highest-density population, while the western part has the highest energy consumption and low-population density. These variations can be referred to as differences in social and economic behaviors of inhabitants in both high-density and low-density population areas. This analysis reflects the influence of several factors that should be taken into account in energy sustainability strategies. Energy consumption is influenced by the characteristics of households which include building size, household income, total energy cost, and building characteristics (e.g., building design, age, location, and using thermal insulation system for buildings).

“…Also, GIS offers the opportunity to manage and automatically process information at larger scales taking into account the spatial dimension and achieving a higher level of detail. GIS capacity to tackle huge spatial databases may support LCA at the territorial scale and reduce the working time to perform the LCA studies in the future [15].…”

“…GIS are based on the combination of spatial data with several attributes and have been demonstrated as effective interdisciplinary tools [28]. Batty and Xie [29] indicated that GIS technology provides the basic framework for processing large volumes of spatial data, obtaining georeferenced information, and producing visual and easily updatable results; therefore, these systems are ideal for creating models that incorporate the attributes of individual buildings [20,[30][31][32][33][34].…”

This study proposes a combined life cycle assessment (LCA) and Geographical Information Systems (GIS) methodology to develop complex LCA inventories for multiple applications. The study focusses on the environmental implications of buildings retrofits, especially in the European context, where the building sector is one of the largest energy consumers. In this context, a new and holistic perspective is needed that expands from the building scale to the urban scale. The combination of LCA and GIS methods includes the development of an urban characterization model based on bottom-up methodologies. The environmental implications associated with increasing the thermal insulation of existing buildings to the current standard are determined based on LCA methods. In this step, common construction systems for building retrofits are used, and insulation materials are compared. Then, absolute and relative extrapolations are performed considering different urban morphologies. The results confirm the importance of the energy retrofitting of residential buildings in large functional urban areas such as the Barcelona metropolitan area, which is examined as a case study. The LCA results indicate that the selection of proper construction systems and thermal insulation materials is important to the environmental performance of building retrofits, and these selections can lead to CO 2 emission differences of up 16% in the region. The relative extrapolation results indicate significant environmental differences between urban morphologies. The LCA results show the potential strategic impacts of the inclusion of LCA methods in retrofit policies at the urban scale. *Revised Manuscript with No Changes Marked Click here to view linked References Highlights A bottom-up methodology is presented to measure and map the environmental implications of retrofit scenarios for residential buildings at the urban scale based on a combined LCA-GIS method. The study compares different construction systems and insulation materials, and significant differences are observed between retrofit scenarios. The method is applied to the Barcelona metropolitan area, Spain, considering the urban morphology as an aggregate method. The results show the potential strategic impacts of the inclusion of LCA approaches in retrofit policies at the urban scale.

The retrofitting of less energy efficient building stock represents one of the most significant challenges in the transition to a low-carbon economy. Nowadays, the housing sector represents about 40% of the energy consumption in the European Union. In this regard, the level of insulation installed in buildings is directly related to the energy efficiency of the building, and consequently to the urban area. In addition, several studies have shown that a comprehensive perspective of energy efficiency is needed, together with calculating the importance of introducing Life Cycle Assessment (LCA) methodology. The purpose of this study is to develop a methodology to: first, measure the energy efficiency level of specific urban areas and their buildings using a geospatial model in an integral perspective; and second, the environmental impact caused by the refurbishment of these building façades using a LCA method.On the one hand, according to a bottom-up framework the quantitative and qualitative characterisation of the building stock façade at the urban scale is possible generating a georeferenced spatial data model of buildings using Geographic Information Systems. On the other hand, the environmental impact of the most usual constructive solutions to refurbishment building façades is calculated using the LCA methodology. The results obtained are merged and interpolated to the urban scale. The methodology is tested for the case study of blocks of flats in Barcelona using the open data of building stock from the Spanish Government. Firstly, this methodology provides more information in regard to urban areas as well as calculating their energy efficiency. Secondly, the study measures the renovation impact of the less efficient buildings. Finally, the results provide the basis for supporting decisions on building stock retrofitting for urban scale from a new approach, especially making the selection between various renovation scenarios much clearer.
