Core Advantages of BESS Containers for Historic Building Retrofits
Non-Destructive Installation: No Drills, No Damage, No Headaches
The biggest selling point of BESS containers lies in their revolutionary approach to integration, standing as the antithesis of a “reno nightmare.” Unlike traditional internal battery systems or complex wired retrofits, BESS containers are strategically installed outdoors, capitalizing on underutilized spaces such as unused courtyard corners, remote parking areas, or the serene edges of gardens. This outdoor-centric installation methodology brings forth a multitude of benefits:
- Preserving Architectural Integrity: By eliminating the need for drilling into historic masonry or frescoed walls, BESS containers safeguard the structural and aesthetic heritage of buildings. There is no risk of compromising the intricate details of ancient stonework or the delicate beauty of painted murals.
- Floor Preservation: Original flooring, often a key element of historic buildings, remains untouched. There is no requirement to tear up these valuable surfaces to lay cables, ensuring that the historic ambiance and integrity of the interior spaces are maintained.
- Minimal Disruption to Conservation Efforts: Ongoing heritage conservation work can proceed without interruption. BESS installations do not interfere with the meticulous restoration processes that are often underway in historic buildings, allowing conservationists to focus on their crucial tasks.
A prime example of the successful implementation of BESS containers is the Leopoldina, a 17th-century Tuscan farmhouse. This historic property underwent a remarkable transformation with the installation of a 500kWh BESS container in its picturesque olive grove. The results were astonishing: a 40.1% reduction in energy demand, all achieved without so much as a scratch on its original stone walls or wooden beam ceilings. In stark contrast, an internal battery system would have necessitated the removal of sections of the farmhouse’s 300-year-old plasterwork, thereby risking damage to hidden mural fragments that may have been preserved within the structure.
Seamless Renewable Energy Integration: Hide the Panels, Keep the Charm
Historic buildings and solar panels have long presented an aesthetic conundrum, a clash between modern sustainability and timeless architectural beauty. However, the advent of BESS containers has changed the game, offering a solution that harmoniously blends renewable energy integration with heritage preservation. BESS containers achieve this by storing energy from low-visibility renewable systems, including:
- Discreet Solar Panels: Solar panels can now be embedded within traditional roof tiles, meticulously designed to match the color and texture of the original materials. This innovative approach ensures that the solar installation remains virtually invisible, preserving the building’s historic facade.
- Strategic Wind Turbine Placement: Small wind turbines can be installed in non-heritage zones, such as fields adjacent to a castle rather than its main courtyard. This strategic placement minimizes the visual impact on the historic structure while maximizing the energy generation potential.
The Château de Montsoreau, a 15th-century French castle overlooking the majestic Loire River, serves as a shining example of this seamless integration. The property installed 300kW of tile-integrated solar panels, which are virtually invisible from the riverbank, and paired them with an 800kWh BESS container. The outcome is remarkable: 45% of the castle’s energy now comes from renewables, and its iconic silhouette, unchanged for 500 years, remains intact. With BESS containers, there is no longer a need to choose between sustainability and heritage; both can be achieved in perfect harmony.
