“…Finally, the energy consumptions trend, in terms of time series and frequency, hailing from different occupants' habits along with the definition of potential strategy for improving the building energy performance, was the object of several works published in the last two years [32][33][34][35][36][37].…”

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 reality, great challenges exist in the choice of representative OB due to both the homogeneity and heterogeneity that is observed in OB. Energy efficiency and energy consumption gaps commonly occur between 9 expectation and actual situations when OB is represented improperly (i.e., when the assumption of OB differs from OB in the real world). In contrast, a proper OB selection close to reality typically leads to suitable building envelope and optimized systems' performances.…”

“…Historically, the occupant behavior related parameters were simplified and considered as a boundary condition like weather, instead of active participants in the buildings [7]. Nowadays, occupant behavior in buildings has drawn a surge of research attention, because more proofs were identified that energy use in buildings is closely linked to occupant presence, movement and interaction with building energy devices and systems [8][9][10].…”

Buildings play a dominant role in global efforts towards energy consumption reduction, greenhouse gas (GHG) emission mitigation, as well as global clean energy transition. Building Energy Policies (BEP) improved globally and quickly with a growing number of building codes implemented over the past decade. Occupant Behavior (OB) has significant impacts on building energy performance and occupant comfort, despite often being not well understood and oversimplified in BEPs. This paper highlighted the research needs of properly integrating OB in building energy polices by presenting a literature review to identify the key questions and challenges related to building technical standards and regulations, building information policies, building energy incentives, and policy evaluations and way forward. Challenges and opportunities of OB in BEP are also discussed with respect to technical innovation and digitalization, as well as concerns related to energy efficiency and fairness. There has been growing interests, research and applications in this field, but significant challenges and opportunities still lie ahead. Keywords: Occupant behavior; building energy policy; climate change policy; building energy efficiency;HVAC system 1. Introduction Occupant behavior in building energy policyBuildings play a dominant role in global efforts towards energy consumption reduction, greenhouse gas (GHG) emission mitigation, as well as global clean energy transition. Facing global climate change and national energy security challenges, international agreements, initiatives, and building sector energy policies are providing 2 promising alternatives to the status quo. In recent years, Building Energy Policies (BEP) improved globally and quickly with a growing number of building codes implemented over the past decade. In contrast, global final energy consumption in buildings increased by more than 5% between 2010 and 2017, as energy efficiency gains were outpaced by continued growth in the building sector size and resulting energy service demands [1]. Among various factors, Occupant Behavior (OB) plays an essential role in building energy demand increases and activity growth. In addition, OB has significant impacts on building energy performance and occupant comfort, despite often being not well understood and oversimplified in BEPs due to its stochastic, diverse, complex and interdisciplinary nature [2]. Definition, estimation and intervention of OB become essential research challenges during building energy policy making, implementation and evaluation processes.

“…Access to spatiotemporally finely resolved occupancy information is necessary for occupant-driven controls and challenging due to occupant stochastic behavior [37]. Sensing technologies are improving to provide information about the temporal and spatial resolutions of occupancy and the knowledge about the occupant behavior [38]. A wide range of algorithmic approaches have been investigated and are currently refined for the purpose of improving the accuracy of building occupancy detection [39].…”

Buildings are widely regarded as potential sources for demand flexibility. The flexibility of thermal and electric load in buildings is a result of their interactive nature and its impact on the building’s performance. In this paper, the interaction of a building with the three interaction counterparts of the physical environment, civil infrastructure networks and other buildings is investigated. The literature review presents a wide variety of pathways of interaction and their associated potential impacts on building performance metrics such as net energy use, emissions, occupant comfort and operational cost. It is demonstrated that all of these counterparts of interaction should be considered to harness the flexibility potential of the buildings while maintaining other buildings performance metrics at a desired level. Juxtaposed with the upside potential for providing demand flexibility, numerous implementation challenges are identified that are associated with the evaluation and financial valuation of the capacity for demand flexibility, the aggregated flexibility potential, as well as the control and communication to facilitate the interactions.
