“…Figure 2 shows total electricity demand reductions by more than 25% in some countries [8], consistent with more recent reports by the International Energy Agency [9]. Table 1 provides more specific data on the impact of lockdowns on the energy demand of the building sector for three countries, with a clear indication that an increase in energy demand of the residential building sector occurred due to the lockdowns while a slowdown of the commercial activities led to a decrease in their energy needs [10]. This type of information suggests the need for continuous monitoring of energy demands at large scales and to use these new data streams to adapt our designs of the built environment to accommodate occupant behaviors including where they are spending most of their time conducting multiple activities, under healthy conditions.…”

The pandemics of COVID19 has disrupted all aspects of our lives in many ways since it was first detected in the early part of the year 2020; personal and professional lives were impacts, work places, learning environments, businesses, commerce, and industry. This complex situation that places buildings at the center of the human activity raises many questions about our state of knowledge and technology to face these extraordinary challenges presented by a global pandemics. To reflect on these complex questions and with the intention of forging a forward agenda for our scientific and engineering community, a group of colleagues organized an initial open conversation at the ASME 2020 Energy Sustainability Conference, held virtually for first time, this past month of June 2020 to reflect on specific and broad topics that included: a) impacts of COVID19 in mechanical systems for indoor environments, b) the role of COVID19 in outdoor environments, c) how CVOID19 has impacted energy demands in buildings with a global perspective, and d) what maybe the role of COVID19 in social equity. Short summaries of these reflections are given in this Editorial Note.

“…In turn, situations more closely related to indoor environmental quality [94,110] and to power consumption patterns before and during lockdown changed in keeping with starting conditions, occupation density (8/12 case studies increase occupancy density by more than 25 percent) and household behaviours during lockdown (11/12 case studies improve thermal comfort; 10/12 improved air quality but did not necessarily translate into sufficient ventilation practices; air quality was lower in the bedrooms on the whole; only 4/12 case studies use the potential of passive measures). Behavioural patterns that depended on circumstances and specific household needs (such as the presence of minors or dependent persons or higher temperature comfort demands) [39] as well as on user commitment to efficient energy use [111] were observed. Only one household adopted energy savings strategies that differed from the other eleven, for instance.…”

“…At more general levels, a significant decrease in energy demand has been observed, although confinements due to social isolation have increased consumption associated with housing [35][36][37]. This alteration would entail important changes in the household economy [38], especially for the most vulnerable population segments [39].…”

Indoor Environmental Quality and Consumption Patterns before and during the COVID-19 Lockdown in Twelve Social Dwellings in Madrid, Spain

et al. 2021

This article analyses the situation that prevailed in 12 dwellings located on the outskirts of Madrid during Spain’s state of emergency. How did 24/7 occupation affect the quality of indoor air and power consumption patterns? The mixed method used (surveys and instrumental monitoring) pragmatically detected the variation in consumption, comfort and indoor air quality patterns before and during the COVID-19 pandemic. The characteristics initially in place and household predisposition had a conclusive effect on such variations. The starting conditions, including household composition, habits and the way daily activities were performed, differed widely, logically affecting power consumption: 8/12 case studies increase occupancy density by more than 25 percent; 11/12 improve thermal comfort; 10/12 improve air quality but not necessarily translate in a sufficient ventilation practices; air quality was lower in the bedrooms on the whole; only 4/12 case studies use the potential of passive measures; only one household adopted energy savings strategies; 10/12 case studies increase electric power consumption but none of the dwellings was fitted with a renewable power generation system. The conclusion drawn is that, despite starting conditions differing widely, household composition, habits (including performance of daily activities performance) and power consumption also played an active role in the end result. This approach allowed to integrate qualitative and quantitative findings on indoor environmental quality (IEQ), energy use and households’ behavior. The objective data on the energy situation of the case studies not only is useful for the study, but also for potential enrollment in energy rehabilitation programs, such as the European Regional Development Fund (ERDF).

“…On the one hand, the view from the energy sector and industry has been widely analyzed, highlighting the decrease in energy demand in global terms, despite the increase in the residential sector [38][39][40]. This would affect certain economies [41] of specific populations [42].…”

Behavior Patterns, Energy Consumption and Comfort during COVID-19 Lockdown Related to Home Features, Socioeconomic Factors and Energy Poverty in Madrid

2021

During spring 2020, the world was shocked at the imminent global spread of SARS-CoV-2, resorting to measures such as domestic confinement. This meant the reconfiguration of life in an unusual space; the home. However, not all households experienced it in the same way; many of them were vulnerable. A general increase in energy consumption and discomfort in many cases, led these families to suffer the ravages of confinement. This study analyzes the energy and comfort situation for the Madrid (Spain) population, according to the configuration of the homes, the characteristics of the dwellings, the vulnerability index by district, and energy poverty (measured with the 10% threshold of energy expenditure of home incomes). The results show a greater exposure, in confinement, of vulnerable and energy-poor households to scenarios of discomfort in the home, to which they could not respond, while energy consumption inevitably increased. Driven by need, energy-poor homes applied certain saving strategies, mainly resorting to thermal adaptation with clothing. This study shows the risk these households experienced in the face of an extreme situation, and invites reflection on preventive and containment measures that aim to avoid harming the disadvantaged in the future; harm that would also entail serious consequences on the health of their cohabitants.
