“…Measurement surveys and laboratory experiments have shown that office environment and IEQ significantly affect worker productivity [ 20 , 21 ]. Studies on thermal environment revealed a correlation between productivity and satisfaction with the thermal environment as well as productivity and air temperature [ [22] , [23] , [24] , [25] , [26] , [27] , [28] , [29] , [30] , [31] ], and findings indicate that people feel more fatigue in humid environments [ 32 ]. Studies on air environment have shown that ventilation improves productivity [ [33] , [34] , [35] , [36] , [37] ].…”

Working from home has drawn more attention with the development of information and communications technology and the coronavirus disease 2019 pandemic. Although studies on working from home have been conducted in various academic fields, few have focused on residential environment and personality traits. In the present study, air temperature and humidity of the home workplace were measured and a questionnaire survey was conducted to understand the relationship between residential environment and personality traits and at-home work productivity. The results suggest that comprehensive productivity while working from home improved. However, when examining individual aspects of productivity, the productivity of information processing improved while that of knowledge processing and knowledge creation deteriorated. The results also suggest the importance of improving the residential environment when working from home because productivity while working from home rather than from the office improved with high evaluation of the residential environment. Moreover, productivity decreased for workers with high neuroticism and increased for those with high openness or perseverance and passion, suggesting that some personality traits are more or less suitable for working from home. To improve the productivity of all workers, these findings have practical implications for promoting appropriate maintenance of the residential environment and introducing flexible work styles that account for personality traits.

“…The modelling approach developed here has potential to inform new building standards, potential upgrades to existing buildings, or investigate policy options such as the Japanese Coolbiz initiative [57] or adoption of equipment or lighting energy efficiency standards etc. Figure 25 illustrates how the typical model could potentially be used with the best and worst case occupancy and behaviour parameter sets and a similar dataset representing variation in weather conditions to illustrate performance across this range.…”

Recently, mandatory and voluntary building codes based on international standards have been increasingly adopted. The performance of existing Egyptian buildings is not well understood making the impact of these new codes uncertain. This paper aims to provide insights into existing Egyptian building performance, and elaborate a process for developing a representative model to assist in future policy. The work presented is for office buildings but intended to be widely replicable. An energy survey was carried out for 59 Egyptian offices, categorised by building service type, it was observed that energy use increases as building services increase, and existing Egyptian offices use less energy than benchmarks. A more detailed investigation for a case study office was carried out, to inform detailed model calibration. This provided insight into energy use, thermal comfort and environmental conditions, and revealed high variability in behaviours. A calibrated model was created for the case study office, then a baseline model and input parameter sets created to represent generalised performance. Future uses including assessment of the impact of codes are discussed, and further replication potentials highlighted.

“…On the other hand, several surveys reveal that many people claim being dissatisfied with the thermal office environment, leading to a decrease in productivity. (1,2) Indeed, despite decades of research and the undeniable progress, the provision of thermal comfort in old buildings is still marred by problems in terms of both its quality and the amount of energy consumed. (3) Despite dedicated energy resources, thermal comfort in buildings remains unsatisfactory.…”

In office spaces, the ratio of energy consumption of air conditioning and lighting for maintaining the environment comfort is about 70%. On the other hand, many people claim being dissatisfied with the temperature of the air conditioning. Therefore, there is concern about work efficiency reduction caused by the current air conditioning control. In this research, we propose an automatic control system that improves both energy saving and thermal comfort of all indoor users by quantifying individual differences in thermal comfort from vital information, on the basis of which the optimal settings of both air conditioning and wearable systems that can directly heat and cool individuals are determined. Various environments were simulated with different room sizes, numbers of users in a room, and heating/cooling conditions. The simulation results demonstrated the efficiency of the proposed system for both energy saving and comfort maximization.
