EcoGen Envelopes is a pioneering initiative aimed at transforming conventional roof tiles into battery-free, energy-harvesting systems for smart buildings. By integrating Thermoelectric Generators (TEGs) and Phase Change Materials (PCMs), the project introduces a novel dual-polarity thermal harvesting approach validated under Dubai’s extreme climate. This innovation enables continuous, silent energy generation from ambient thermal gradients, supporting autonomous operation of wireless IoT sensor networks without reliance on batteries. The project combines materials science, energy engineering, and AI-enhanced digital infrastructure to deliver a scalable, field-tested solution. Key components include a thermoelectric roof tile prototype, an AI-powered simulation platform for energy yield and system optimization, and edge-computing-enabled sensor nodes for real-time environmental monitoring. Field deployments at two Dubai sites will demonstrate performance, durability, and integration potential. EcoGen Envelopes directly supports Dubai’s sustainability and smart city goals by reducing electronic waste, enabling predictive maintenance, and enhancing climate-resilient infrastructure. The project fosters local innovation through collaboration with international and UAE-based manufacturers and contributes to talent development via workshops and technical documentation. Supported by Heriot-Watt University’s incubator and IP teams, the commercialization roadmap includes feasibility studies and stakeholder engagement to ensure market readiness. Aligned with the Dubai Future Foundation’s RDI Grant Program under the Cognitive Cities sector, EcoGen Envelopes addresses critical challenges in climate-neutral urban systems and next-generation built environments. It positions Dubai as a global leader in sustainable infrastructure and deep-tech entrepreneurship, offering a replicable model for integrating AI-driven microgeneration into urban design.
