Natural energy sources cleverly used
IBC is committed to a world in which more is produced with less. A world in which we cover our energy needs and still conserve resources. Nature provides us with heat and cold reserves that we can use sustainably. We generate heat from groundwater, waste water and renewable wood. With our heating and anergy network, we supply you locally with sustainable energy for heating and cooling.
Heat Briefly Explained
Climate-friendly heat supply
The transformation of Chur's heating supply plays a central role in achieving the “Chur Energy Master Plan 2040”. The aim is to replace fossil natural gas and oil heating systems with renewable heating systems. With our heating and anergy network, we want to cover around 60 percent of Chur's heating requirements with CO2-free, renewable energy by 2040. Check the progress of the heating network expansion in Chur here anytime.
If you convert your heating supply to an IBC heating or anergy network, you will benefit from corresponding subsidies. These are already included in our availability check.
You can also find detailed information on possible subsidies at energiefranken.ch
Heat-Contracting
If your property is located in Chur in the area of an anergy network, you have the option of having IBC install and operate the heat pump centers for the provision of heat, domestic hot water and cooling energy.
If you are interested, we will check the possibilities and conditions individually.
Our heating and anergy networks
In Chur, we already operate an extensive heating and anergy network which we expand over a majority of Chur's area . A heating network which is fuelled by renewable wood chips is also available in Churwalden.
IBC is also actively involved in Fernwärme Chur AG, Wärmeverbund Domat/Ems AG and Energieverbund Maienfeld AG and is responsible for the operative management of these organisations.
Regardless of the technology used, the connected customers make an important contribution to reducing CO₂ emissions.
Plant examples
Insights into some of IBC's energy supply systems.
Fortuna energy center
- commissioning: Jul< 2024
- heating output: 4 MW
- Energy source: local groundwater
The Fortuna energy center was put into operation in July 2024. With an investment volume of around 8 million francs, it is a major milestone in the implementation of the goal of supplying IBC customers in the city of Chur with CO2-free heat by 2040. The local groundwater serves as the energy source. With a total output of 4 MW (2 x 1 MW heat pump, 2 x 1 MW gas redundancy) heating output, the energy center supplies the Fortuna and Herold school buildings and the adjacent district with renewable heat for space heating and domestic hot water. The plant is part of the generational project of reorganizing the school and sports facilities in the city of Chur.
Churwalden energy center
- commissioning: 2021
- heating output: 1.9 MW
- Energy source: regional wood chips
The Churwalden energy center was put into operation in 2021. A particular challenge for the planning of the plant was the varying customer needs throughout the year due to the geographical altitude. Customers must be reliably supplied both during the higher performance requirements in winter and during the greatly reduced power consumption in summer. The use of local wood chips ensures great added value in the region.
When fully developed, over half of the residents will be supplied with heat for space heating and domestic hot water from the Churwalden energy center all year round.
Combined heat and power plant City West
- commissioning: 2011
- thermic output: 1 MW
- electric output: 1 MW
The City West and Kornquader combined heat and power plants form an important part of the heat supply that the IBC offers. The larger of the two CHP plants is located in the City West shopping center, the complex opened in 2011 with two striking high-rise buildings, a hotel, apartments and various shops. Thanks to the high energy efficiency of the plant, in addition to the important heat supply in winter, additional electricity is also generated to operate the heat pumps.
Trist 2
- commissioning: 2024
- heating output: 280 kW
- Domestic hot water: 33 kW
- Air conditioning cooling capacity: 245 kW
- Energy source: local groundwater
As part of a contract, IBC supplies Domenig Immobilien's Trist 2 residential and commercial development with heat and cooling energy from the bidirectional anergy network Chur West. IBC is responsible for the financing, installation, operation and renewal of the system, from the anergy network up to and including the heating storage tank after the heat pump and the free cooling heat exchanger.
A particular challenge for the planning was the creation of well-founded load profiles for future use without knowledge of the future tenants. The two heat pumps for heating and hot water were successfully put into operation in spring 2024
