“…By identifying residential clusters with the percentage of each building archetype in Greater London, the present study can be expanded from the building level to the city level, with a focus on low-income households. This is crucial for future energy planning and policymaking, considering the complexities and interconnections of extreme events [15], including wars (such as in Ukraine), particularly for low-income households, in achieving the energy and climate targets set for 2050.…”

Covid-19 has caused great challenges to the energy sector, particularly in residential buildings with low-income households. This study investigates the impact of the confinement measures due to the Covid-19 outbreak on the energy demand of seven residential archetype buildings in Greater London. Three levels of confinement for occupant schedules are proposed and compared with the base case before Covid-19. The archetypes, their boundary conditions, and input parameters are set up according to statistics from English Housing Survey (EHS) sample data for low-income housing. The base case scenario (normal life without confinement measures) is validated against the measured data energy consumption from the National Energy Efficiency Data-Framework (NEED) statistics. The results show that electricity consumption is significantly lower than that for heating and hot water for all the archetypes. By comparing the base case scenario with the full Covid-19 lockdown scenario, the results indicate that heating and hot water consumption (kWh) for all the residential archetypes increases, on average, by 10%, and total electricity demand (kWh) increases by 13%. The study highlights the importance of introducing detailed occupancy profiles in multi-zone building energy simulation models during a pandemic that leads to a greater shift towards home working, which may increase the risk of fuel poverty in low-income housing.

The growth of the leading countries’economies leads to the rapid development of megacities and changes in urban areas. Currently, more and more modern high-rise civil buildings are being built, resulting in an increasing density of urban areas and the activity of transport infrastructure. This causes major changes in the structure of urban development, which leads to a change in aeration and microclimatic conditions in urban areas. Solar radiation plays an active role in shaping the microclimate of the urban space, which aggravates the heat and wind regime of the urban environment. This is especially acute in the southern cities with hot climatic conditions. The article analyzes modern urban areas and factors affecting their microclimate. The role of temperature inversions in the formation of microclimatic conditions is indicated. Using the example of the yard space in Dushanbe, measurements and field studies were carried out; graphs of the climatic indicators of the urban area were plotted. The role of solar radiation in the formation of convective flows and microclimatic conditions of urban space is discussed.

“…Moreover, accurately forecasting buildings electricity load is challenging due to the dynamic and diverse nature of occupant behaviors, which are often not directly observable. Occupancy data is crucial [4,21] but difficult to obtain due to privacy concerns, the absence of occupancy sensors in legacy buildings, high sensor installation costs, and issues related to sensor accuracy. Researchers have explored various proxy information sources for occupancy sensing, such as Google search trends [15], positional records from Twitter [28], Call Details Recore [8], Wi-Fi-derived occupancy [29], Bluetooth low energy on mobile devices [43], domestic water consumption [16], and indoor carbon dioxide measurements [46].…”

Figure 1: This figure illustrates the impact of the first COVID-19 lockdown (indicated by the red region) on the electricity load of a building complex located in Melbourne's Central Business District (top graph). Concurrently, it presents the effect on the average human mobility throughout the city, as measured by pedestrian count (bottom graph). The diagram clearly shows significant shifts in distributions during the lockdown, which do not fully revert to their pre-lockdown state even after restrictions are lifted.
