OverGrid AI specializes in smart energy management, aiming to introduce energy flexibility to hotels through a human-centric and environmentally responsible approach.

OverGrid AI
Detailed presentation

OverGrid AI helps hotels reduce air-conditioning energy costs without compromising guest thermal comfort. The solution combines a smart controller with a digital management platform and uses occupancy, thermal comfort, weather forecast and energy market data to optimize HVAC operation. The system dynamically adjusts air-conditioning operation so that energy is used more efficiently and, whenever possible, during periods of higher renewable energy availability. In this way, OverGrid AI enhances energy flexibility without changing the user experience or requiring replacement of the existing HVAC system.

The problem

Hotels are trying to reduce their energy costs while maintaining high levels of thermal comfort for guests, in order to avoid negative reviews and complaints. Air conditioning represents a major flexible load and is key to both energy and economic performance. However, the right balance must be found so that thermal comfort, which is directly linked to the guest experience, is not compromised.

At the same time, as the energy transition progresses and more renewable energy enters the energy mix, electricity becomes more available and more affordable, particularly during midday hours. When renewable energy production is higher than demand, the grid becomes unbalanced and the operator must reduce renewable energy production.

The market still lacks affordable, integrated and easy-to-deploy solutions that combine energy savings, energy flexibility and thermal comfort, especially for hotels with existing or older HVAC systems and without advanced energy management.

Our proposal

OverGrid AI offers hotels a simple way to use their air-conditioning systems to enhance energy flexibility. The solution combines a smart controller with a digital energy management platform. It integrates with the existing HVAC system without changing the way guests use it, allowing them to retain full control through the standard controller. The smart controller records system settings and operating patterns, while the platform uses occupancy, thermal comfort, weather forecast and energy market data to dynamically optimize HVAC operation.

The result is lower energy costs, greater use of renewable energy and improved energy flexibility, without compromising thermal comfort. The business model combines hardware sales with subscription-based services, using tiered pricing according to the level of data, analytics and control required by each hotel.
