Zagorje ob Savi, Slovenia
overview acticities
1. Pilot mine water exploitations for direct heating in OLEA
facility.
2. Retrofitting municipal building, culture centre, kindergarten
3. Setup of first charging stations for electric vehicles in the
region.
4. Completed a community energy monitoring and
management system in public facilities.
5. Solar photo voltaic power plant connected to the public grid
and operational.
6. Expanded biomass district heating grid completed; project
documentation for a further expansion.
7. Retrofitting of existing residential buildings (500 units).
Zagorje, Slovenia – small scale

low exergy direct surface heating with minewater,
building envelope in the standard of passive buildings,
phase change materials for heat and cold storage,
solar thermal collectors for sanitary hot water preparation and support of
heating,
ventilation system with waste air heat recovery with highly efficient
regenerators,
cooling of the building via a ground air heat exchanger,
energy efficient LED electrical light,
solar photo voltaic cells and direct methanol fuel cell for electrical selfsufficiency,
advanced control systems on the basis of weather forecast and
responsive systems management,
rain water storage,
dry compost toilet with waste water treatment in constructed wetland.

Application for recovery of energy
Barredo University Buildings
250 m
Research Centre: Originally planned: gas
boiler (700 kw) and air- water chiller for cold
production, chanced to heat pump and using
minewater. The heat circuit was designed for a
temperature of 50 degree not the most efficient
rate for the heat pump
Hall of Residence: only heat production.
Originally planned gas boiler and radiant floor
at 35ºC (excellent for heat production by heat
pump technology using minewater, so the
geothermal system was also adopted).

Novoshaktinsk, Russia
•Three wells (200/400m)
•Heat pump 0,4 MW with gas fired boilers (6MW) for peak and
back-up
•Grid to several existing buildings (school, hospital etc.)
•Buildings in bad shape (no retrofitting)
•High temperatures still needed
School in Bad Schlema, Germany
Drilling direct near location
No distribution system
Direct use in combination with heat pump

Gardanne France
Depth Well Y (Morandat) 1109 m
Depth Well Z 880 m
Constant temperature in the well (25 °C)
Water highly mineral-bearing > Impossible to use directly
Possible application in Gardanne

Activity and business area at the well Morandat (58 000 m² for
office)
Aquatic center (Open from may to august)
Nelson MANDELA Media library
Market (3 500 m²)
Urban development of Mistral district (20 000 m²)
The water temperature (25 °C) requires the use of heat pumps :
– Decentralised solution : a grid of water distribution at 25 °C to
production unit at the bottom of buildings.
– Centralised solution : a single heat production site with a heating grid
(55 °C/45 °C) and a cooling grid (10 °C/15 °C), and a delivery of such
energy through substations located in the buildings.
• Current state of play: feasibility studies in progress (almost
completed)
