Power outages during peak hours in Kuwait can seriously impact the comfort of indoor spaces, especially during the intense summer heat. When cooling systems go offline, even for a short time, indoor temperatures can rise quickly, making homes uncomfortable and potentially unsafe. This study looks at how these energy limitations affect thermal comfort inside buildings and proposes a cyber-physical energy assessment framework aimed at improving energy efficiency while reducing discomfort during critical periods. We examine household temperature conditions, adaptive comfort techniques, and real-time power usage data using a mixed-method approach. Results show that outages during peak hours cause extreme heat stress, which causes residents to use ineffective cooling techniques. To help buildings better cope with power outages, the proposed cyber-physical framework brings together energy management systems, smart sensors, and predictive modeling. By combining these elements, the study aims to strike a balance between keeping occupants comfortable and using energy more efficiently. It also offers practical insights that can benefit homeowners, energy planners, and policymakers looking to make buildings more resilient and sustainable in challenging climates. This study highlights the urgent need to adopt smart energy solutions that can improve everyday living conditions in Kuwait while also addressing broader challenges related to long-term energy sustainability.
