“…This makes it possible to assume that its activity allows identifying new patterns associated with an increase in the level of balanced development of economic activities and assimilation potential of the region with an increase in the share of renewable energy in its energy balance (Dvinin & Nikolaeva, 2020). As the share of renewable energy in the energy balance increases, the level of the economic balance of the regional socio-ecological and economic system will also change (Keiko et al, 2016).…”

“…Recently, renewable energy has been widely developed; its peculiarity is that it uses energy already circulating in the biosphere, i.e., unlike traditional energy, it does not significantly affect the change in natural material and energy flows [10]. This suggests that its activities allow identifying new patterns associated with an increase in the level of balanced development of economic activity and the region's assimilation potential with an increase in the share of renewable energy in its energy balance.…”

The balance assessment of biosphere material and energy flows and those resulting from economic activity in the industrial region is carried out. The analysis is based on the use of stability indicators of the region's socio-ecological and economic system. For balance assessment of material and energy biosphere flows and economic activity, the total material input criterion was used, where the consumed natural resources are reduced to a single value. It was found that the functioning of the energy sector operating on fossil fuels created significant imbalances in the material and energy flows. The balance indicator is calculated for the regions of the Ural Federal District. In all regions of the Ural Federal District, except for the Yamal-Nenets Autonomous Area, the balance indicator is higher than the presence of general instability. The study allowed determining the magnitude of the ecological and economic effect in developing promising renewable energy sources. In 2 regions of the Ural Federal District, the scenario of replacing traditional energy with renewable energy will reduce the material intensity, which means that it will increase the level of balance of material and energy flows by more than 10 times.

“…Hori et al [18] investigated the optimal renewable energy system composed of photovoltaic panels, wind turbines, small and medium scale hydropower plants, geothermal power plants, and biomass cogeneration plants for cities and municipal areas in Japan. For a city, the effects of the renewable energy systems on CO2 emissions, biomass resource circulation rate, and impacted ecosystem area have been analyzed in detail.…”

Recently, the integration of renewables such as photovoltaic panels, solar water heaters, ground-source heat pumps, and fuel cells into buildings is increasing.The increase of building-integrated renewables affects the energy mix, energy flows from the grid, CO2 emission, and energy system cost in cities.The urban-scale effects of increased building-integrated renewables have been investigated on a representative district (a Dong) in Seoul. Unlike the previous studies which did not consider non-solar renewables and the energy system configurations different for each building, this research considers the optimal building energy system (including ground-source heat pumps and fuel cells) for every building obtained by Linear Programming. Hourly electricity, cooling, and heating loads of each building have been estimated using the database of monthly electricity and gas usages in every building. The total capacity and energy supply of each renewable energy source, the renewable energy mix in residential and non-residential sectors, and variations in the electricity and gas flows from the grid to the district have been analyzed in detail.To carry out the investigation on a large city, the problem of long calculation time caused by a large number of buildings should be overcome. For example, the investigation on Seoul (over 10 5 buildings) may take more than two months. This research proposes a new framework for fast and accurate estimation of the total capacities and energy supply of the renewable energy sources and the variations in the energy flows from the grid in a large city (e.g. less than 2 days for Seoul). To reduce the number of optimizations, buildings with same building type, similar monthly electricity and gas usages, and similar roof area are categorized as a cluster, then a virtual representative building is generated for each cluster. Results from the optimizations for the representative buildings are linearly scaled considering the number of buildings and the total energy usage of each cluster. Consistency between the results from the proposed framework and the results from the optimization for every actual building has been validated by a case study on an aggregation of multiple districts (a Gu).Using the proposed framework, the collective effects of building-integrated renewables on a large city (Seoul) has been investigated for the first time. Two applications of the framework have been demonstrated− 1) the expected results of a future scenario of an obligation for building-integrated renewables; and 2) the variations in a total reduction in CO2 emission and the cost of a unit reduction in CO2 for varying renewable energy requirements for buildings. The framework developed by this research can be used as a reliable tool for quantitative policy design related to dissemination of building-integrated renewables.
