|Demonstration Description||ENERTUN (Energy Tunnel Segmental Lining) technology consists in an improved tunnel precast segmental lining for tunnels constructed by TBM equipped to exchange heat with the ground in order to heat and cool adjacent buildings. |
A circuit of pipes is installed in each segment in the factory before precasting and a fluid circulates through them allowing for heat exchange with the ground. Each equipped segment is connected to the adjacent one through hydraulic connections to form a ring of segmental lining. The pipes are positioned so that their main direction is perpendicular to the tunnel axis. This system allows maximising the heat exchange and reducing the hydraulic head losses.
This technology was patented in 2016 (https://www.knowledge-share.eu/brevetto/enertun-conci-prefabbricati-per-geotermico/) and its main advantages are the high heat exchange, the low hydraulic head losses, the rapid installation and the low cost.
The system was installed in the tunnel of the Turin Metro Line 1, 40 m North from the Bengasi station. The experimental site is active with two rings of thermally activated segments, a heat pump and a secondary system for the usage of the heat recovered.

Frequently Asked Questions
We have fund our selves at a crossroads. Buildings energy efficiency is not moving fast enough to meet the Paris Agreement goals. Innovative financial instruments, business models and regulatory frameworks are urgently needed.
We can continue in this direction. Or we can explore a new way forward. The encyclopenergy aims to do just that in a bid to streamline and optimise the way the built environment community shares knowledge.
The enclyponergy aims at creating a comprehensive compendium to support the spread and scale of innovation in financing solutions, business models, and regulatory frameworks to accelerate the transition to a less carbon-intensive built environment.
The project ‘Climate Positive Circular Communities’, short name ARV, is funded by the European Green Deal initiative as an Innovation Action within the Horizon 2020 Framework Programme. The enclycopenergy is a flower germinating from the ARV in order to map the world state of art when it comes to energy efficiency financing, business models and regulatory frameworks. The Green Digital Finance Alliance as an ARV Consortium partner is in the lead of such an effort.
The Encyclopenergy is a crowd-open-sourced encyclopedia of energy efficiency enablers. It is a crowdsourced global catalogue of financing tools, business models, and regulatory frameworks enabling, empowering, and scaling energy efficient solutions for the built environment. It also offers intelligence to list demonstrations and organization working in the field with the hope this will be a boomerang to boost the renovation wave.
Everywhere. Ubiquitus. Onlline. And in your pocket. The encyclopenergy wants to be a practical tool available to all at all time. You can surf it, download it and populate it from anywhere.
The encyclopenergy is still in its infancy. It was kickstarted on March 1st 2022. Help this living knowledge hub to grow, refine and ameliorate so that it can graduate into a useful tool for a climate positive built environment.
