VAV Energy Storage: Transforming Energy Management for Sustainable Living

The Innovative Energy Storage Project

VAV Energy Storage, formerly known as LANCEY Energy Storage, offers the only system that optimizes photovoltaic self-consumption to reduce electricity bills. This innovative solution combines a renewable energy storage battery with a next-generation electric radiator that integrates an intelligent battery. It is designed to improve thermal comfort while maximizing energy savings. Born from the ambition to make sustainable comfort accessible to as many people as possible, the project utilizes a cloud-based Energy Management System that helps reduce and better manage energy consumption. The system is perfect for individual housing, collective dwellings, and tertiary sectors, and its unique approach has even garnered a strategic partnership with Conicio and Bosch, celebrating the “made in Auvergne-Rhône-Alpes” spirit.

Main Benefits at a Glance

The solution delivers more than just renewable energy storage capabilities. Key features include:

• Achieve 90% photovoltaic self-consumption easily
• Use stored electricity all year round thanks to the associated micro-inverter and the system’s intelligence
• Optimize peak/off-peak subscriptions and reduce subscribed power
• Achieve 35% savings on heating bills
• Enhance thermal comfort with sensors and innovative management
• Equip homes with equipment designed and manufactured in France at competitive prices

Optimizing Energy Consumption

The system takes photovoltaic self-consumption to a whole new level. Photovoltaic panels produce renewable and local energy, though their peak production occurs during the day when homes are often empty. Here’s where the integrated storage battery steps in, storing the unused energy during daylight hours. When production declines, the energy stored in the battery is used as a priority by an intelligent management system that powers daily electrical needs. This streamlined production/consumption cycle ensures that clean energy is available anytime the sun isn’t shining… all thanks to the innovative design of the battery integrated inside an electric radiator.

Enhanced Comfort and Building Value

In addition to energy optimization, the project has a significant impact on thermal comfort and the overall valuation of properties. The system replaces traditional electric heating with a solution that is both smarter and more cost-effective. The result is enhanced thermal comfort through innovative management and sensor technology. Property owners, landlords, promoters, builders, and hotel operators benefit from improved energy labels and greater property value. Moreover, the ease of installation by a network of qualified professionals ensures that even those with modest budgets can enjoy the benefits of renewable energy and comfortable living environments.

Cutting Costs and Promoting Renewable Energy

This project isn’t just about saving energy—it’s about transforming the way energy is used in everyday life. The innovation extends to replacing conventional electric heating with a solution that not only lowers costs but also offers heightened comfort and efficiency. For individuals, it’s an innovative way to reduce heating bills, achieve smoother solar self-consumption, and enhance everyday comfort. The simplicity of installation, maintenance, and the accessible use of the system make it a valuable asset even during construction or renovation projects. The project truly demonstrates that renewable energy can be both efficient and affordable, providing a pathway towards minimizing energy poverty.

Expanding Applications Across Sectors

The integrated system is designed to be versatile and user-friendly, making it an attractive solution for a wide range of sectors. Whether it is individual housing, large-scale collective projects, or tertiary sectors like office buildings and hotels, the offering delivers consistent benefits. The technology also supports the management of distributed storage and consumption, allowing for a centralized management approach that is as simple as it is intelligent. Consumers can easily monitor their photovoltaic production and consumption through dedicated applications, ensuring transparency in energy usage and simplifying energy management without sacrificing comfort.

Future Prospects and European Impact

As VAV Energy Storage embarks on new projects to extend its product range and expand commercial deployment, the vision is clear: to become a leading European player in the thermal comfort market. With a track record of ensuring renewable energy is used efficiently and sustainably, the system is an exemplary case of innovation meeting real-world needs. The responsiveness of the cloud-based energy management system, coupled with the intelligent integration of storage in modern heating solutions, drives the energy transition forward. Through strategic partnerships and a strong commitment to sustainability, the project creates value for a broader European audience and beyond. This dynamic approach supports a future where energy use is not only efficient but also truly transformative, supporting quality of life and environmental stewardship for all.

What Lancey actually does

Lancey (branded VAV Energy Storage) is a Grenoble-based company founded in 2016, making intelligent electric radiators with integrated battery storage, combining photovoltaic self-consumption optimization, energy storage, and smart connected heating in a single device. Products are designed and manufactured in France, and the technology holds Solar Impulse Efficient Solution certification.

Where the technology shows up

• Home heating: intelligent radiators with built-in battery storage, letting households store and use solar energy for heating instead of drawing from the grid.
• Collective housing: versatile enough to be deployed in individual homes or larger multi-unit residential projects.
• Manufacturing partnership: products built with Bosch at its Marignier facility, and co-branded with Conicio to promote Auvergne-Rhone-Alpes manufacturing.

Proof, not just claims

Lancey’s technology has won the CES Innovation Award (2018), the EDF Pulse Award in the Smart Home category, and the FNAC/Darty Startup Prize, and is NF-LCIE certified.
