WAS KANN ICH IM RECHNER WÄHLEN?

Der Rechner erlaubt es Ihnen den Anteil des Energieverbrauchs zu wählen, der in der Schweiz von Solarthermie gedeckt werden soll, in den Jahren 2035 oder 2050. Eine Erhöhung des Anteils an zentralisierten Heizeungen, hat eine proportionale Verminderung dezentralisierterer Heizungen zur Folge

AUSWIRKUNGEN - WELCHE AUSWIRKUNGEN HAT fernwärme?

Der Ausbau von Fernwärme wird in der Schweiz folgende Auswirkungen haben:

Energiesysteme

image Reduce primary and final energy demand.

image Likely to decrease electricity demand by displacing electric forms of decentralised heating, unless the share of centralised heat pumps increases significantly.

image Likely to reduce total consumption of heating oil and natural gas as centralised boilers and cogeneration are more efficient than decentralised solutions.

image Impact on the grid depends on the type of technologies chosen.

image Likely to increase energy independence by decreasing fossil fuel imports.

Environment & Climate

image Very likely to reduce global CO2 emissions.

image Likely to reduce deposited waste.

image Other impact categories are technology specific.

Society & Economy

image Cost of the energy transition, impact on Balance of payments and Confederation income, depend on the technologies chosen.

GLOBAL MARKET – What is the global market for District Heating?

District Heating has an average market share of 10% in Europe, but in North, Central and Eastern Europe, this can be as high as 50% and more.[1] Heating is the largest energy end-use in Europe and is responsible for around 50% of total final energy consumption. 70% of total primary energy demands are concentrated in urban areas, suggesting a large fraction of the primary energy demand could be met with District Heating.

DEFINITION / CONSTRAINTS

DEFINITION - What is District Heating?

With District Heating, heat that is generated ‘centrally’ is distributed through a network of pipes to the end users (a household or medium or large size industrial facility). The heat can be generated with various technologies and in the calculator, Central Heating is represented by the following technologies: Centralised Heat pump, Cogeneration, Centralised Boiler and Deep Geothermal.

CONSTRAINTS - What are the key barriers facing District Heating deployment?

• Requires district heating infrastructure (network) which can be capital intensive to deploy, particularly as a retrofit.

• Currently low energy prices make the economics of such an integrated energy system quite challenging without significant policy drivers.

ASSUMPTIONS – What are the assumptions considered in the calculator?
