“…Another interesting observation in the results of Figure 5 is that the base case value of 22 • C, which is very common in the UAE and other countries in the Gulf region [3,32,33], results in sub-optimal conditions for the building occupants (i.e., PPD = 11%). This observation leads us to question whether it is adequate to apply standards developed in Western countries (e.g., ASHRAE to other regions such as the Arabian Gulf, or not, where a temperature of 22 • C might be considered comfortable by building occupants.…”

“…Given the academic nature of the facilities, which are typically open to students and/or staff around the clock, values of 24 • C are chosen to reflect more relaxed temperature values compared to occupied set points (i.e., 22 • C), while maintaining acceptable indoor conditions in case the space becomes occupied beyond regular working hours. Moreover, choosing unoccupied temperature settings that are close-or even similar-to those of occupied hours is common when modeling buildings in the UAE and other Arabian Gulf countries such as Kuwait [3,32,33], which further supports the choice of 24 • C as a set point for unoccupied periods. Next, the building energy models are run, generating energy intensity estimates (i.e., site electricity demand) of 257.1 kWh/m 2 /year for the typical office building, 195.1 kWh/m 2 /year for the classroom building, and 363.9 kWh/m 2 /year for the dorm building.…”

There is a growing interest in the literature to understand how actions taken by occupants and facility managers can affect building performance. However, user-centric building energy research: (1) remains understudied compared to design-focused research efforts; (2) overlooks combined effects or uncertainty in multiple parameters; and (3) typically does not cover particular types of buildings (e.g., educational facilities), nor buildings subject to extreme weather conditions. This paper fills an important gap in the literature by proposing a comprehensive energy modeling and analysis framework to quantify the impact of human action on building energy consumption. The framework applies various data analysis methods such as differential, fractional factorial, and Monte Carlo analysis methods, in order to capture potential combined or synergetic effects of human actions on building performance. A case study is then presented on typical educational buildings located in the extreme hot climate of Abu Dhabi, United Arab Emirates (UAE). Results indicate that uncertainty in human actions can lead up to a ±25% variation from average energy consumption levels, confirming the significant role that people have in making their built environment more efficient and sustainable.

“…Ameer and Krarti [7] explained why Kuwait was finding it difficult to meet the demand for electric energy during the summer season, namely, the fact that 95% of the electricity bill of each residential house is subsidized gives residents little incentive to conserve electricity. This subsidy places a significant financial burden on the government and ultimately affects all Kuwaitis negatively.…”

In Kuwait, where the government subsidizes approximately 95% of residential electricity bills, most of the country's energy consumption is for residential use. In particular, air-conditioning (AC) systems for cooling, which are used throughout the year, are responsible for residential electric energy consumption. This study aimed to reduce the amount of energy consumed for cooling purposes by developing a thermal comfort-based controller. Our study commenced by using a simulation model to investigate the possibility of energy reduction when using the predicted mean vote (PMV) for optimal control. The result showed that control optimization would enable the cooling energy consumption to be reduced by 33.5%. The influence of six variables on cooling energy consumption was then analyzed to develop a thermal comfort-based controller. The analysis results showed that the indoor air temperature was the most influential factor, followed by the mean radiant temperature, the metabolic rate, and indoor air velocity. The thermal comfort-based controller-version 1 (TCC-V1) was developed based on the analysis results and experimentally evaluated to determine the extent to which the use of the controller would affect the energy consumed for cooling. The experiments showed that the implementation of TCC-V1 control made it possible to reduce the electric energy consumption by 39.5% on a summer representative day. The results of this study indicate that it is possible to improve indoor thermal comfort while saving energy by using the thermal comfort-based controller in residential buildings in Kuwait.

“…The energy performance of residential villas in Kuwait and their energy efficiency potential has been examined by a number of researchers [20][21][22][23][24][25][26][27][28][29][30]. A recent study by Ameer and Krarti [20] develops a base case energy model for a prototypical Kuwaiti villa and undertakes a series of analyses to determine the impact of energy efficiency measures, while considering the country's high subsidized energy prices. Al Ragom [22] also uses energy modelling to develop various retrofitting cases that represent potential retrofitting scenarios, concluding that substantial energy savings can be achieved at the national level even when implementation costs are supported by the government.…”

This paper investigates the physical and social determinants of energy use in four case study villas in Kuwait. The investigation consisted of a 12 month mixed-method longitudinal monitoring and surveying study followed by building energy modelling. Monitoring and surveying provided empirical data about household energy use, internal temperatures, building and system characteristics and occupant energy-use behaviours. This data was used to ground models to better predict energy use. Models grounded with empirical data show that space cooling accounts for 50% to 75% of total energy use in villas. Results suggest that drivers of cooling energy are varied, with 30% of cooling energy in some villas attributable to heat gains from appliances. Furthermore, while the study found no distinct reduction in measured and modelled annual energy use intensities of villas with improved levels of efficiency (insulation and double glazing), such measures did contribute to more uniform internal temperatures. The study also identified key occupant energy-consuming behaviours including a tendency not to adjust air conditioning (AC) thermostat settings during periods of summer travel and lack of regular AC maintenance. The approach and findings of the study can inform future studies in Kuwait seeking to understand energy use in a nationally representative sample.
