“…The energy consumptions resulting from simulations are immediately compared with the actual ones entered by the user [54,55] and with the elaborated benchmarks. Those ones were computed on the basis of the Italian TSO report [39] and of the ISTAT survey on household energy consumption [56].…”

This work shows the outcomes of a research activity aimed at the energy characterization of residential users. Specifically, by data analysis related to the real energy consumption of sample buildings, the flexible loads amount has been identified so as to investigate on the opportunity to implement a demand/response (DR) program. The most meaningful input data have been collected by an on-line questionnaire created within an Excel spreadsheet allowing one to simulate and compare the calculations with the actual dwellings’ consumption; 412 questionnaires have been used as statistical sample and simulations have been performed based on single-zone dynamic model. Additionally, once the energy consumptions have been sorted by the different services, reference key performance indicators (KPIs) have been also calculated normalising those ones by people and house floor surface. From data analysis, it emerges how the Italian residential users are not very electrified. Furthermore, the flexible loads are low and, implementing minor maintenance interventions, the potential of flexibility can decrease up to 20%. For that reason, the current research can be further developed by investigating on suitable flexibility extensions as well as on the automation system requirements which is needed managing the flexible loads.

In this year, 2020, the Covid-19 pandemic has imposed new challenges for most human activities. Time-geography is a theoretical approach with great potential for analysing the consequences of the new disease and other disturbances, and this article aims at identifying possible developments of interest for the approach in the post-Covid era. The article addresses challenges that emerge for time-geographic research from the perspective of massive changes in human behaviour, regarding time-space activity patterns, caused by the globally diffusing disease. The implications of the pandemic are discussed with respect to four areas: (i) time-geographic techniques; (ii) activities and rhythms; (iii) activity spaces; and (iv) social issues and perceptions. The time-geographic concepts to be scrutinised are constraints, virtual time space and bundles, and stations and paths. In addition, the article introduces this Special Issue of the Moravian Geographical Reports on ‘Current issues, methods and applications in time-geography’, contributions which for evident reasons were written before the onset of the pandemic.

“…Clearly the aggregated data used in this paper cannot determine per sector consumption patterns, nor can it provide evidence of specifically which electricity services and energy-using practices changed during the UK's Covid-19 lockdown. This must wait for more detailed analysis of per sector electricity consumption data and especially in-home appliance data as a proxy for energyusing practices (Durand-Daubin 2013;Palmer et al 2013a;Suomalainen et al 2019).…”

Covid-19 lockdown: impacts on GB electricity demand and CO<sub>2</sub> emissions

In early 2020 a wide range of social and economic restrictions were implemented in most countries in response to the global coronavirus pandemic (Covid-19). This paper uses national electricity generation data to examine the extent to which overall British electricity consumption deviated from 'normal' consumption patterns during the UK's spring lockdown period, and how the combination of consumption reduction and variation in carbon intensity affected greenhouse gas emissions (GHG) associated with electricity consumption. The paper shows that ongoing trends in the reduction of electricity demand and generation carbon intensity mean that lower year-on-year demand and lower emissions would have been expected even in the absence of Covid-19. Controlling for this, the paper estimates lockdowndriven below-trend electricity reductions of up to 20% in the morning peak period, 11% in the daytime and 9% in the evening peak period in April, declining to 6%, 4% and 4%, respectively, by June. These correspond to marked reductions in morning (06:00-08:00 hours) and daytime demand during all restriction periods studied, but relatively smaller reductions in evening demand, and some evidence of a relative increase on Friday and Saturday evenings. PRACTICE RELEVANCE The observed changes in demand are likely to be repeated in future national or local restriction periods and provide insights of value for grid and local distribution network management. This is especially true if such restrictions are required in spring 2021, as looks increasingly likely, but are also relevant to the winter 2020-21 heating season, which is likely to exacerbate the demand for electric heating, although gas remains the dominant heating fuel source in homes. However, unlike fossil fuel-based transport, the changes observed do not translate to direct emissions reductions due to the mixture of fuels used to generate electricity in Britain. Electricity generation emissions were either close to or above the trend during this period, and the effect is especially noticeable for the traditionally carbon-intensive evening peak period.
