The Sustainable Beauty of Vatican Museums

Overview of the Project

 

In December 2023, the Vatican Museums launched a unique sustainability project aimed at combining ecological transition with respect for their historical heritage

 

The project began with a study of the glass roof at the main entrance, aiming to install new photovoltaic panels capable of producing renewable energy and regulating temperature without compromising aesthetic harmony. 

 

The result is a project that embodies the concept of sustainable beauty, demonstrating how technology can seamlessly integrate into a universally recognized cultural site.

Acea’s commitment: Phases of the Project

 

The project spanned 12 months, running from December 2023 to December 2024.
To accommodate the nearly 30,000 daily visitors, Acea developed an internal and external scaffolding system
to ensure safety. To achieve this, most of the work was carried out at night.

 

Two construction cranes enabled simultaneous work on the north and south sides of the structure,
speeding up operations and ensuring efficiency and precision. Thanks to this solution, the work was completed within the agreed timeframe, respecting the scheduled opening of the
 Holy Door on December 24, 2024.4.

Photovoltaic Panels

Photovoltaic Panels

 

The installed photovoltaic panels use glass-glass BIPV (Building Integrated Photovoltaics) technology, ensuring resistance and durability.
The density of the cells has been optimized to strike a balance between transparency and shading, enhancing indoor comfort by protecting from high temperatures while allowing natural illumination.

 

These panels not only produce energy but also serve as a functional element that enriches the structure and enhances its beauty without intruding on the spaces of the original building.

From Emissions Reduction to the Integration with Historical Architecture: The Challenges of the Project

Sustainability and energy efficiency

 

  • Renewable energy production

  • Better thermal insulation

  • Reduction of energy consumption

  • CO2 emission reduction

Comfort and enhancement of spaces

 

  • Greater indoor shading

  • Greater environmental comfort

  • Total architectural integration

  • Better aesthetic and design

A Sustainable Future

 

The photovoltaic system at the Vatican Museum is just the beginning of a larger journey for Vatican City. Different projects are already underway, such as the installation of charging stations for electric cars and the gradual removal of combustion vehicles, further reducing the environmental impact.

 

With the addition of the new 221 kWp photovoltaic system inside Magazzini Vinaccia, the Vatican will reach a total capacity of 350 kWp, solidifying its role as a sustainability model.
