“…Tam et al (2018) mencionam em sua revisão bibliográfica alguns autores que categorizaram todos os temas, de todos os sistemas de avaliação de "vizinhança verde" (bairros sustentáveis), em 9 aspectos, dentre os quais pode-se observar a categoria que enfoca os próprios edifícios, os quais não aparecem isolados, mas de forma integrada a um contexto maior, que é o de neighbourhood (vizinhança, bairro, comunidade), conforme se vê na Figura 1. Le Guen et al (2018) corroboram essa visão, que parte do edifício em direção ao bairro (ou à vizinhança), quando afirmam que as três ações elencadas a seguir são procedimentos importantes e estreitamente relacionados, no que diz respeito ao atendimento da demanda da construção de bairros:…”

“…Segundo esses autores, cada um desses procedimentos deve ser avaliado separadamente e depois ligados para fornecer a melhor estratégia aos tomadores de decisão no planejamento (LE GUEN et al, 2018). Por meio dos estudos de Tam et al (2018), Garau e Pavan (2018) e Le Guen et al (2018) percebe-se que, quando se pretende discutir a sustentabilidade, relacionando-se determinados edifícios ao contexto urbano onde estão inseridos, a questão da eficiência energética é um ponto marcante e que atuará como fio condutor dessa discussão.…”

“…The advantage of using such a methodology is the optimization of the size of the batteries based on the demand. However, the drawback to this, is that the energy produced is not often consumed locally and hence the full potential of the generation of the system is not used [38,23]. In order to address this,…”

A simulation tool is developed to make a comprehensive techno-economic and environmental assessment of a case study under different scenarios. Different capacity of solar and storage technologies are considered. The model calculates the levelized cost of electricity, the autonomy level and the CO 2 emissions. We demonstrate that the economic profitability of solar and battery system is in very good agreement with HOMER and the autonomy level is validated by using a simulation tool created by SI-REN. We show that combining solar PV with battery system doesn't bring additional autonomy to the model for Geneva considering the present market prices for batteries and seasonal changes in solar energy potential. The validated tool is then extended to include the thermal demand and generation by adding heat pumps and solar thermal. The availability of thermal storage at a large scale and the generation over a neighbourhood are shown to increase the autonomy of the neighbourhood. Finally, multiple scenarios are also run by changing the input parameters to perform a sensitivity analysis of these parameters on the performance of the model. Under the assumptions of the model, to foster investments in solar PV and battery installations, falling investments costs seem necessary for the future.

“…Combining urban climate and building simulation models are important in this context [12]. Similarly, renewable energy potentials for installation of wind turbines and solar PV/thermal should be considered in order to evaluate the potential to integrate renewable energy technologies [59]. The main campus site of EPFL is blessed with both solar and wind energy.…”

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.
