“…The acceptability of an open window is determined by the conditions outside, despite window opening behavior being triggered by indoor discomfort and non-physical variables [44]. In this view, smart window control systems, based on both the analysis of outdoor environmental conditions and the perspective of occupants, could achieve true building energy and comfort efficiency [45]. However, it should be noted that no significant literature was found about motorized windows surrounding human-building interactions.…”

“…Through an experimental campaign in educational buildings, Belafi et al [57] found that classrooms in the same boundary conditions had different window-related behaviors and thermal comfort, illustrating that motivations of occupant interaction with windows are not limited to the achievement of thermal comfort [45], [58] or related to purely non-physical, (i.e. daily schedule and habits) or physical drivers (e.g., season, type of HVAC system, etc.)…”

“…A significantly higher number of interactions were observed in instances where ease of control accessibility was high (manual control with web interface). In addition, in the residential sector, researchers found that the interactions with roller shades changed depending on the room of the house, especially among the seasons [45]. The motivations of occupant's interaction with shades are not only attributable to environmental parameters and optimization of energy use.…”

In recent years, research has emerged to quantitatively and qualitatively understand occupants' interactions with buildings. However, there has been surprisingly little research on building interfaces and how their design, context (e.g., location), and underlying logic impact their usability and occupants' perceived control, as well as the resulting comfort and energy performance. Research is needed to better understand how occupants interact with building interfaces in both commercial and residential applications; both applications are important to address as there are many differences in interface types, level of control and understanding, and even expectations of engagement. This paper provides a cursory review and discussion of select common building interfaces: windows, window shades/blinds, thermostats, and lighting controls. The goal of this paper is to review literature related to these human-building interfaces to explore interface characteristics, current design and use challenges, and relationships between building interfaces and occupants. Human-building interface interactions are complex, more research is needed to understand design, use, and characteristics. Common themes emerged throughout the literature review to explain occupant interactions (or lack of interactions) with building interfaces, which included thermal and visual comfort, ease and access of control, interface/control placement, poor interface/control design, lack of understanding, and social-behavioral dynamics.

“…Based on the results of the Pearson correlation test (Table 13), the relationship between the PET index with thermal comfort in the selected points of A and C was significant (p-value < 0.05) and was of inverse correlation (−0.404 and −0.379 ) . Due to the medium correlation coefficient (medium = −0.3 to −0.5) [90][91][92], the relationship between the PET index and the PTC in area A (p-value = 0.004) was more significant that of area C (p-value = 0.006). Moreover, the significance of PET index relationship with perceived thermal comfort in area B (p-value = 0.061) was not accepted (p-value > 0.05).…”

The Cooling Effect of Large-Scale Urban Parks on Surrounding Area Thermal Comfort

et al. 2019

This empirical study investigates large urban park cooling effects on the thermal comfort of occupants in the vicinity of the main central park, located in Madrid, Spain. Data were gathered during hot summer days, using mobile observations and a questionnaire. The results showed that the cooling effect of this urban park of 125 ha area at a distance of 150 m could reduce air temperatures by an average of 0.63 °C and 1.28 °C for distances of 380 m and 665 meters from the park. Moreover, the degree of the physiological equivalent temperature (PET) index at a distance of 150 meters from the park is on average 2 °C PET and 2.3 °C PET less compared to distances of 380 m and 665 m, respectively. Considering the distance from the park, the correlation between occupant perceived thermal comfort (PTC) and PET is inverse. That is, augmenting the distance from the park increases PET, while the extent of PTC reduces accordingly. The correlation between these two factors at the nearest and furthest distances from the park is meaningful (p-value < 0.05). The results also showed that large-scale urban parks generally play a significant part in creating a cognitive state of high-perceived thermal comfort spaces for residents.

“…This conservative saving level is used in this analysis specific to the Arab region to account for the diversity of climate conditions, behavioral changes, and energy efficiency rebound effects [59][60][61]. In particular, the impacts of occupant behavior on the energy efficiency of the built environment can be significant even though these impacts depend on several factors and remain difficult to quantify for a large-scale analysis [62][63][64]. The benefits of integrated design based BEECs applied to the new buildings are estimated and are summarized as shown in Table 21.…”

The paper overviews the current energy demand trends in the building sector for the Arab region using reported historical energy consumption. Moreover, the paper describes the current energy efficiency policies and regulations for all the Arab countries specific to both residential and commercial buildings. Finally, the paper evaluates potential benefits for large-scale energy efficiency programs specific to new and existing building stocks within the Arab region using a bottom-up analysis approach. The analysis of the available energy consumption for all the Arab countries has shown that the Arab region presents a significant variation in energy consumption levels between its sub-regions and countries. Indeed, the Arab region includes oil-producing countries such as Saudi Arabia with the largest energy use per capita in the World with over 9000 kWh/person of electricity used annually in buildings. However, the same region has the least developed countries such as Sudan and Yemen with the lowest energy use per capita in the World with barely 100 kWh/person/year of electrical consumption. The review of the existing regulations has indicated that several Arab countries have not implemented any energy efficiency codes and standards for building envelope, lighting, heating and cooling equipment, and appliances. A cost-effectiveness analysis has indicated that the Arab region can incur significant benefits in upgrading the energy efficiency of its new and existing buildings especially its households. Specifically, the adoption and the enforcement of stringent energy efficiency codes for new residential and commercial buildings can result in a reduction of 12.7 TWh/year in final annual energy consumption for the Arab region. Moreover, retrofit programs targeting existing buildings can save up to 470 TWh or a third of the building sector final energy consumption per year after 2030. Combining comprehensive energy efficiency requirements for new buildings and extensive retrofit programs for existing buildings would reduce the total final energy consumption of the building sector in the Arab region by 600 TWh by 2030 and by 900 TWh by 2050 if all the energy programs start to be implemented by 2020.
