District Heating Network Kortrijk

The City of Kortrijk installed a pilot heatnet at Kortrijk Weide, as a nucleus for further extensions in the city. The feasibility to install a heatnet backbone from the waste incinerator at the outskirts of the city, along the River Leie, to the city center was researched. As many building projects are taking place along the river, this would create the opportunity to connect over 1,000 households.

Heating with Woodchips in Güttenbach

The biomass heating plant and district heating grid in Güttenbach (Austria) was built in 1997. The boilers are fired with wood chips from local forests. There are two boilers installed, one biomass boiler with 1 MW capacity and one oil boiler for peak load and backup with 1.3 MW capacity. The village of Güttenbach has about 900 inhabitants and an area of 16 km2. The district heating grid has a length of 12 km with about 240 connected consumers. Each year there are 5,200 MWh heat sold to the consumers.

Ensuring energy security and cost- efficient heat supply

The district heating system of Brasov has gone through several transformations in the attempt to find a solution for the zones located within the urban agglomeration of Brașov. Unfortunately, the lack of vision and the misun- derstanding of the advantages of such a system, coupled with a legislation that allows for easily installing natural gas individual boilers, led to a situation where only 4% of the local population was still connected to the DH in 2014 (reference year of the project).The future of this system is directly linked to the local policies, which should be supported by the population, by the real estate developers and last but not least, by policy makers.

The current strategy is trying to provide insight into the renewable sources that could be used in the future in order to ensure energy security and cost efficient heat supply at local level.

Geothermal energy for ensuring sustainable and affordable heating & cooling

The city of Litoměřice developed an Energy Concept in 2009 and adopted a Municipal Energy Plan in 2014. The main goal of the municipality is to reduce energy consumption by 20 % by 2030 (baseline year 2012). There are no specific targets regarding renewables (RES) in Litoměřice in the heating and cooling sector.
The city is developing a Sustainable Energy and Climate Action Plan as part of the Covenant of Mayors (www. eumayors.eu), which will define specific targets for RES.

Renewable heating strategy for a new development area

This case study covers the investigation of renewable heat supply options for the new development area «Teilraum 31» in Ansfelden. The area is mainly owned by the municipality which, therefore, can define priorities regarding energy efficiency and renewable energy. The new development area could include ca. 120,000 m2. According to the current planning strategy, it will be used for different types of buildings – mainly residential ones, and could reach a plot ratio of 0,45 to 0,55 per building lot. The expected buildings consist of around 100 single-family houses, 200 row houses and 10 small multi-family houses.

District heating in Bornholm and Bornholms Forsyning

In 2008, the Regional Municipality of Bornholm decided to become a 100% sustainable and CO2-neutral society in 2025, in which only sustainable and renewable energy is used. In 2019, already 60% of the island’s energy is produced fossil-free by using wind, sun and biomass power. The island’s green vision, big share of renewable energy, citizen and community involvement and replicability of the energy solution helped in winning the 2019 RESponsible Island Prize.

Regional Action Plan – Friuli Venezia Giulia

The ENTRAIN project aims at improving the capacities of public authorities to develop and implement local strategies and action plans for enhancing the use of endogenous renewable energy sources (RES) in small district heating (DH) networks. As part of the project there have been set up five initial surveys and local action plans for a specific region. The outcomes of the Regional Action Plan for Friuli Venezia Giulia are briefly described.
