Technical Abstract:

Problem Statement:

Modern urban infrastructure is fragmented in addressing energy production, air quality, and thermal regulation. Current systems operate independently, creating inefficiencies:

• Solar panels generate energy but lack air purification or heat reduction.
• Green roofs require high maintenance, irrigation, and structural support for limited cooling.
• Air filtration units depend on grid power, worsening the energy burden they aim to reduce.

These systems are static, unable to respond dynamically to pollution spikes, traffic surges, or heatwaves. For example, solar panels cannot reorient to sudden cloud cover, while air filters lack energy-saving modes during low-pollution periods. This rigidity causes wasted energy (up to 40% overproduction) and underused surfaces (e.g., roads, façades).

Cities urgently need adaptive, multifunctional technologies to maximize surface utility, minimize waste, and bolster climate resilience—core goals of AEROLEAF AIRGRID.

Solution:

AEROLEAF AIRGRID is a modular, AI-optimized environmental mesh that transforms urban surfaces into adaptive, self-sustaining systems. Each 100 cm² tile combines:

• Perovskite thin-film photovoltaics (23% efficiency) for solar energy,
• MOF-808 metal-organic framework passive CO₂ capture membranes,
• Piezoelectric nanocomposites harvesting vibration energy (1W/10 m²),
• Reinforcement learning algorithms coordinating tile networks to optimize energy distribution and airflow.

The AI system uses reinforcement learning to dynamically adjust tile behavior based on real-time weather forecasts and traffic density data, optimizing energy storage and CO₂ capture based on environmental demand.

MOF-808 was selected for its superior CO₂ adsorption efficiency—offering nearly twice the capacity of alternatives like MOF-74—along with high thermal stability and scalability.

Tiles autonomously adjust tilt/porosity via shape-memory alloy actuators (Nitinol) and communicate via ESP32-based mesh protocols, enabling city-scale load balancing.

Novelty:

AIRGRID is the first system unifying energy harvesting, CO₂ capture, and AI-driven coordination in a single modular tile. Unlike solar skins (e.g., Mitrex) or air-filtering facades (e.g., AlgenAir), AIRGRID’s shape-memory substrate increases efficiency by 22% in simulations by bending to optimize sun exposure and airflow. Its AI prioritizes energy allocation (e.g., routing surplus power to EV charging stations during rush hour).

Feasibility:

Prototype simulations (EnergyPlus, MATLAB) validate performance:

• 90 Wh/day energy/tile (vs. 70 Wh for standard PVs),
• 5–10 mg/hr CO₂ capture (comparable to 1 mature tree/tile),
• 4°C surface temperature reduction vs. asphalt controls.

Each tile is designed for 25-year durability under urban conditions and has passed ASTM G154 UV exposure tests and IP67 ingress protection for outdoor deployment.

Tiles use PET-G recyclable polymer bases and snap-fit connectors compatible with existing injection-molding infrastructure. Mass production costs are projected at $12.50/tile (10kunit batches), with a 2.8-year payback period via energy savings and carbon credits.

Applications:

Prioritizes public transit retrofits (e.g., EV charging stations, bus wraps) and ASEAN cities battling urban heat islands (e.g., Singapore’s Green Plan 2030). Partnerships with Siemens (smart grid integration) and GAF Energy (roofing deployment) are underway. Targets the
$312B smart cities market (ABI Research, 2027) with a 30% cost advantage over hybrid solar/filter systems.

Initial launch includes a pilot deployment of 500 tiles along Singapore Bus Route 12 in Q2 2024 to evaluate energy, air quality, and passenger comfort improvements.
