“…For that reason, it is now rather important to synthesise building technology and energy efficiency research with social science, as an effort to understand the interconnection between humans and buildings. Occupancy and representation of people's behaviour in an office is important and has a direct effect on the building's energy performance [ 22 ]. Human behaviour is stochastic, so it is difficult to define the number of people occupying a specific space, as well as the duration of the occupancy [ 108 ].…”

“…The relationship between the number of employees and the required office space grew arithmetically in parallel to each other. Moreover, activity patterns in offices were considered relatively steady and mainly related to typical working hours [ 22 ]. Nowadays, however, a more dynamic model of office work is prevailing, and this is also expected to affect the occupancy and operation of office buildings.…”

“…An increasing amount of research published in current literature has focused on the operational energy consumption in office buildings and more specifically on the energy-relevant interaction of occupants with buildings [ [17] , [18] , [19] , [20] , [21] , [22] , [23] , [24] , [25] ]. Other studies have analysed various aspects of human-building interactions, focussing primarily on the socio-psychological factors that affect energy-saving behaviours in the workplace [ 20 , 26 , 27 ].…”

As a result of COVID-19 and in order to combat the spread of the virus, work-from-home and remote working has become a widely accepted practice in professional settings globally. It is widely known that we are currently experiencing a highly transient period in terms of how we define work. Office work is progressively becoming more collaborative, modern workforce more mobile, and office occupancy more dynamic. As flexible working evolves, it becomes apparent that the role of workspace is also changing. So will the occupancy patterns and operation of office building. Using a mixed-method approach, this paper explores the future of offices, considering flexible working model and investigates the operational energy consumption of UK office buildings in the post-pandemic era. Previous research has shown that office buildings are one of the five largest sectors in the building stock in terms of energy consumption. The results of this study demonstrate that by embracing emerging transitions in hybrid working model and activity-based workspace environments, the energy demand in the office building sector could fall below pre-COVID-19 levels, with significant energy savings reaching up to 50% energy reduction in comparison to the pre-pandemic situation.

“…Such a methodology is an important issue for our future work. Last but not least, it is necessary to emphasize that, in order to manage the energy of IBs in an efficient manner, all of the solutions mentioned in the previous sections must consider other nontechnological aspects, which are very often forgotten, including the human dimension [243,244] as well as environmental challenges, such as climate change [245,246].…”

Intelligent Buildings in Smart Grids: A Survey on Security and Privacy Issues Related to Energy Management

During the last decade, the smart grid (SG) concept has started to become a reality, mainly thanks to the technical progress achieved in telecommunications, informatics and power electronics, among other domains, leading to an evolution of the traditional electrical grid into an intelligent one. Nowadays, the SG can be seen as a system of smart systems that include cyber and physical parts from different technologies that interact with each other. In this context, intelligent buildings (IBs) constitute a paradigm in which such smart systems are able to guarantee the comfort of residents while ensuring an appropriate tradeoff of energy production and consumption by means of an energy management system (EMS). These interconnected EMSs remain the objective of potential cyber-attacks, which is a major concern. Therefore, this paper conducts a survey, from a multidisciplinary point of view, of some of the main security and privacy issues related to IBs as part of the SG, including an overview of EMS, smart meters, and the main communication networks employed to connect IBs to the overall SG. Future research directions towards a security enhancement from both technical and human perspectives are also provided.

“…22 One of the main factors contributing to the performance gap is related to the varying nature of occupant behaviour. 11,14,16,23 This can be partially linked back to inaccurate predictions made during building design, especially when the end user is unknown. Furthermore, the occupiers themselves are prone to misunderstand and misuse building systems, alter hours of occupancy and prioritize thermal comfort over energy efficiency.…”

Energy use in buildings accounts for one-third of the overall global energy consumption and total building floor area continues to increase each year as new developments are constructed and delivered. If stringent climate goals are to be met, these buildings will need to consume less energy and emit less carbon. However, design intentions for energy efficient buildings are not always met in practice. This performance gap between calculated and measured energy use in buildings threatens the progress necessary to meet these energy targets. The aim of this paper is to identify the factors that contribute to the performance gap and propose solutions for reducing the gap in practice. A quantitative and qualitative analysis of two research programmes completed in the past few years was utilized for an in-depth look at the performance of around 50 non-domestic buildings in the United Kingdom. While no direct links were found between any one variable and the performance gap, several correlations exist between contributing factors indicating a complex, entangled web of interrelated problems. The multitude of the variables involved presents a formidable challenge in finding practical solutions. However, the results indicate that the combination of the ventilation strategy of a building and the building services control strategy during partial occupancy is a key determinant of the performance gap. A more straightforward procurement approach with clearly delineated targets and responsibilities, along with advanced and seasonal commissioning instituted at the beginning of a project and implemented after building completion can also be very effective in reducing the gap. Finally, mandatory requirements or an appropriate system of incentives for monitoring and disclosure of performance data can help identify many of the underlying issues affecting performance in-use and untangle some of the web of complex issues across the building sector. Awareness of the performance gap and knowledge of the factors contributing to its impact on the building industry is important for all stakeholders involved in the design, construction, operation and occupation of non-domestic buildings. Understanding potential solutions to mitigate these risks may help to reduce the prevalence and magnitude of the performance gap.
