“…Hybridizing the two approaches has been used for unit commitment problems related to power systems, 30,31 although it has not been applied to energy system design before. We used the dispatch strategy proposed by Perera et al 5 (as explained in Supplementary note 03) to consider complex interactions for the unit commitment problem, addressing the limitations with the entire time series models described in recent literature. We used graphical processor unit (GPU) computing to increase the number of scenarios through large scale parallelization while reducing the computational time.…”

Climate induced extreme weather events and weather variations will affect both energy demand and energy supply system resilience. The specific potential impact of extreme events on energy systems has been difficult to quantify due to the unpredictability of future weather events. Here we develop a stochastic-robust optimization method to consider both low impact variations and extreme events. Applications of the method to 30 cities in Sweden, by considering 13 climate change scenarios, reveal that uncertainties in renewable energy potential and demand can lead to a significant performance gap (up to 34% for grid integration) brought by future climate variations and a drop in power supply reliability (up to 16%) due to extreme weather events. Appropriate quantification of the climate change impacts will ensure robust operation of the energy systems and enable renewable energy penetration above 30% for a majority of the cities. 2According to the Fifth Intergovernmental Panel on Climate Change (IPCC) report, 1 climate change will most likely accelerate, causing increasingly frequent and strong extreme climate events that make humans, as well as built and natural systems, more vulnerable to those events. Failure to address climate change mitigation and adaptation could lead to disaster and serious short-and long-term issues, 2 including partial or total blackouts due to energy supply disruptions. 3 These consequences could be very costly to cities and urban areas. Currently, 3.5 billion people live in these areas, consuming two-thirds of global primary energy and producing 71% of the directly energy-related global greenhouse gas (GHG) emissions. By 2050, urban areas are expected to hold more than half of the world's population, which will multiply the costs and impacts. 4 Therefore, the urban sector plays an important role in both climate change adaptation and mitigation. Conserving energy and using renewable energy technologies in these areas will be essential to minimize the carbon footprint of the energy infrastructure. Distributed energy systems that support the integration of renewable energy technologies will support the energy transition in the urban context 5 and play a vital role in climate change mitigation and adaptation.Climate change affects the energy use of urban areas extensively, by influencing energy demand, generation, systems and infrastructure. 6,7 Renewable energy generation can be affected in various ways, too, depending on the renewable source (e.g., wind, hydropower or solar) 8,9 and geographical location. 10 Due to extreme weather events, impacts of climate change on peak electricity demand will reach well beyond simple changes in net annual demand and become more critical due to their influence on system design and power supply. 11,12 For example, Sweden's existing residential building stock may experience an approximate 30% decrease in 20-year average heating demand during 2081-2100 compared to 1991-2010, while during extreme conditions the hourly heating and cooling demand may reach betwe...

“…Different computational tools have been developed to perform this specific task as reviewed by Lund et al [170]. In addition to the computational tools available, some studies have proposed computational algorithms to conduct energy system optimisation [171]- [173]. The basis of the assessment has changed from simple economic analysis into eco-environmental assessment focusing on the carbon emissions during the recent past.…”

Reviewed assessment methods for the urban environment • Critically analysed papers working on urban climate and energy demand, outdoor thermal comfort and the urban energy systems. • Demonstrated the links between the processes • An integrated workflow is proposed for assessment of the urban environment. AbstractThe current climate change is calling for a drastic reduction of energy demand as well as of greenhouse gases. Besides this, cities also need to adapt to face the challenges related to climate change. Cities, with their complex urban texture and fabric, can be represented as a diverse ecosystem that does not have a clear and defined boundary. Multiple software tools that have been developed, in recent years, for assessment of urban climate, building energy demand, the outdoor thermal comfort and the energy systems. In this review, we, however, noted that these tools often address only one or two of these urban planning aspects. There is nonetheless an intricate link between them. For instance, the outdoor comfort assessment has shown that there is a strong link between biometeorology and architecture and urban climate. Additionally, to address the challenges of the energy transition, there will be a convergence of the energy needs in the future with an energy nexus regrouping the energy demand of urban areas. It is also highlighted that the uncertainty related to future climatic data makes urban adaptation and mitigation strategies complex to implement and to design given the lack of a comprehensive framework. We thus conclude by suggesting the need for a holistic interface to take into account this multi-dimensional problem. With the help of such a platform, a positive loop in urban design can be initiated leading to the development of low carbon cities and/or with the use of blue and green infrastructure to have a positive impact on the mitigation and adaptation strategies.

Building more energy efficient and sustainable urban areas that will both mitigate the effect of climate change and adapt for the future climate, requires the development new tools and methods that can help urban planners, architect and communities achieve this goal. In the current study, we designed a workflow that links different methodologies developed separately, to derive the energy consumption of a university school campus for the future. Three different scenarios for typical future years (2039, 2069, 2099) were run as well as a renovation scenario (Minergie-P). We analyse the impact of climate change on the heating and cooling demand of the buildings and determined the relevance of the accounting of the local climate in this particular context. The results from the simulations showed that in the future there will a constant decrease in the heating demand while for the cooling demand there will be a significant increase. It was further demonstrated that when the local climate was taken into account there was an even higher rise in the cooling demand but also that the proposed renovations were not sufficient to design resilient buildings. We then discuss the implication of this work on the simulation of building energy consumption at the neighbourhood scale and the impact of future local climate on energy system design. We finally give a few perspective regarding improved urban design and possible pathways for the future urban areas.
