Setting sustainable standards with bioenergy villages

The heating market accounts for more than 40 percent of energy usage and the largest proportion of energy consumption; it therefore plays a significant role in the achievement of agreed political climate targets. The installation of advanced, highly efficient systems would save the heating market up to one third of its energy.

Bioenergy villages can contribute to this saving. All households are supplied from a local heating network whose energy is generated from renewable fuels on the outskirts of the village. These fuels come from agricultural resources which are processed in a biogas plant, or from local forests. Every bioenergy village is therefore a strategic sustainability project which protects the climate and environment, and in an ideal scenario, does not consume fossil fuels such as oil or gas.

Low initial outlay

It usually costs around €4500 per household to connect to the heating network of a bioenergy village. This includes a contribution to the operator association, which is usually a cooperative. Compared with a conventional oil heating system, the price for heating is around 10 to 20 percent lower. In fact, savings during operation increase continually over several years. The CO2 savings achieved are in excess of 50 percent.

Viessmann – a partner to be relied upon at every stage

As a complete supplier of energy systems, Viessmann offers all the necessary components from a single source. In conjunction with our Group members, we supply not only the right heating systems for renewables. Instead, the services offered within the scope of integrated project development include the initial consultation, preparation of feasibility studies and cost-benefit analyses, engineering work in cooperation with regional engineering firms as well as complete implementation of the project as a general contractor.

At the same time, cooperation between Viessmann, regional service providers and local construction companies is very important with regard to value creation and securing jobs in the region. In addition, Viessmann supplies a standardised control system to operate all the heat generators and the heating network itself.

Futureproof and economical

To create a bioenergy village or even a partial solution, Viessmann has the ideal futureproof and economical energy system to meet every demand.

Renewable local heating offers many benefits for residents and local authorities

The criteria for a bioenergy village are quite straightforward. The community is usually rural and has between 500 and 1500 residents.

Secure and economical supply

The energy centre should be designed and constructed outside the village to avoid congestion for the residents from deliveries of the necessary biomass. The energy centre is designed to permit an extremely reliable supply of heating water and domestic hot water at all times. Seen over several decades, every household invests just once to become connected and then has no further outlay.

Permanently lower heating costs help ease the budgets of households, and create scope for other investments. These might include insulation, for example, to further reduce heat consumption. Strengthening the regional economy and easing the budget. The biomass required for heat generation usually comes from nearby sources. This strengthens regional economies, as well as the local forestry and agricultural industries. It also involves value creation, investment and job security. Furthermore, savings from a cheaper heat supply for public buildings help to relieve the budget of the local authority.

Replacing conventional heating

In smaller communities that mainly consist of detached houses, the typical fuel until recently has been oil. With renewable local heating networks, the individual heat source in the house makes way for a heat transfer station the size of a wall mounted gas boiler, which records the actual consumption via a heat meter. This also means oil tanks are superfluous, allowing for their removal and making dirt and the smell of oil a thing of the past. The space this creates could be used for a hobby room, for example.

Locational advantage thanks to low energy costs

The status of a bioenergy village makes it a more attractive place for developing industrial estates. Existing and new businesses have a locational advantage as they can profit from the considerably lower energy costs compared to oil and gas.
