The largest Abbey of Europe goes to renewable energy
Photo Gallery
The Loire Valley is an outstanding cultural landscape of great beauty, containing historic towns and villages, great architectural monuments, and cultivated lands formed by many centuries of interaction between their population and the physical environment, primarily the river Loire itself.
The Abbey of Fontevraud, in the heart of the Loire Valley World Heritage site, is impressive both in its size and by the strength of its history. It is one of the largest monastic cities from the Middle Ages.
The Abbey has undertaken an ambitious and daring energy conversion project, for which the major achievement was the construction of the Energy Centre, aimed at achieving 100% self-sufficiency in heating and electricity by means of a combination of biomass boilers and photovoltaic cells.

Sustainable Fontevraud
Establishing the Abbey as a living site also requires working on the conservation of buildings, and improving the comfort offered to users by relying on new technologies, and the latest advances in sustainable development. To adapt its practices to the requirements of preserving natural heritage, Fontevraud has set up several resource management projects: waste, greenery, lighting, transporte, etc.
With regard to energy efficiency, building renovation projects systematically include insulation measures based on the installation of double-glazed windows which maintain their historic appearance The Abbey has an automated and centralised system for lighting management when necessary (sensors in all areas frequented by the public) Photo Gallery. This system has allowed reducing by 90% the consumption of electricity for lighting since 2009.
The complex also has a fleet of electric vehicles that closes the cycle of energy self-sufficiency from renewable energy sources and reduces emissions generated by transport.
But the most important and innovative project is the Energy Centre, inaugurated in 2013. It combines several energy resources with a wood boiler, solar panels but also rainwater collection and waste recycling.

The Energy Centre is the first new building at the Abbey in a century, and the first major achievement of the Fontevraud Sustainable city programme, and as such is a unique experience in France in a historical monument. Photo Gallery.
Partly buried, the building rose out of the ground, fitting perfectly into the site’s architecture and landscape. Its roof garden/terrace provides a choice scenic setting for holding concerts and shows against the backdrop of the abbey church’s chevet, which boasts a remarkable architectural style.
Energy self-sufficiency has been achieved through the careful integration within the complex of this new infrastructure that includes two boilers each with 500kW capacity and 92 PV panels, which will replace fuel and electric heating.
The objectives identified in the program of energy conversion are:
- Decrease by 2 energy consumption compared to 2011
- Decrease by 4 Photo Gallery 2011
- Cover 90% of energy needs from renewable energy
- Ensure 100% supply through local resources.
The wood pellets supplying the heaters are produced in the Saumur region. Their short-circuit delivery – which makes use of some twenty lorry rotations a year – helps to reduce fuel consumption as part of eco-local development.
Not far from Fontevraud, in Saumur, the École Nationale d’Équitation has fitted thermal and photovoltaic solar panels onto the Cadre Noir Ring and its stables to generate electricity and hot water.

This example is focused on self-sufficiency of renewable energy supply, and as such it achieves the additional advantage of energy security for the site. Photo Gallery, and thereby also protect the Heritage Significance of the site at the urban district scale.
The Abbey of Fontevraud example shows a model to follow in the large historical heritage complexes.
