Biomass-based renewable heating initiative of the University of Sopron
About this good practice
The University of Sopron places great emphasis on the implementation of sustainability principles in its daily operations.
The problems addressed were the greenhouse gas emissions and the reliance on fossil fuels, which contributed to environmental harm and financial instability. The aim was to develop a biomass-based supply for the University's building services systems and to promote the uptake of decentralised, environmentally friendly renewable energy systems. The initiative also aimed to tackle the inefficiency and high operational costs of the existing heating systems by transitioning to sustainable, renewable energy sources.
The energy upgrade resulted in the completion of 3 new heating plants, aiming to fully replace fossil-based thermal energy. The development has resulted in the construction of a new concrete building, where a 2 MW biomass boiler and associated wood chips storage facility operates. The supply of raw materials (wood chips) is also ensured in the long term on the basis of an agreement with TAEG Zrt. (an educational forestry).
Beneficiaries
- University: improved heating efficiency and sustainability
- students, teachers, staff: enhanced environmental quality and sustainability awareness
- local community: improved air quality and reduced greenhouse gas emissions
Stakeholders
- University (implementation)
- the EU and Hungarian Government (funding)
- TAEG Zrt. (supplier of raw materials)
- local authorities, energy firms (collaboration, execution)
Resources needed
The Széchenyi 2020 Programme (KEHOP-5.2.2-16-2023-00168) provided EUR 5.9 million in EU funding for a project involving nearly 100 people. It included a general construction contract covering equipment, construction, and execution costs. The inauguration event was self-funded.
Evidence of success
The 3 heat centres heat 22 buildings with a total heated surface area of 56726.4 m2. Thanks to the investment, the University can reduce its greenhouse gas emissions by 1,675.85 tonnes of CO2 equivalent per year, making it the first Hungarian university to become climate positive. A total of 3 700 kW of additional capacity was implemented, which can generate 15 861.67 GJ/year of renewable energy. The annual reduction in primary energy consumption of public buildings is 4406020 kWh/year.
Potential for learning or transfer
This practice is a successful transition from fossil fuels to renewable energy, reducing greenhouse gas emissions. It demonstrates valuable insights into enhancing energy efficiency in public and institutional buildings. The financial benefits, such as reduced operational costs and stable energy supply, offer a model for achieving long-term economic sustainability. The project highlights the importance of multi-stakeholder engagement, involving the university, government, local authorities, and energy firms. The use of the biomass boiler and wood chips storage facility with automated systems provides a technological blueprint for adopting innovative energy solutions. Additionally, it fostered sustainability awareness among students, staff, and the local community. This comprehensive model for integrating renewable energy, improving energy efficiency, and achieving economic and environmental benefits makes it valuable for regions aiming to enhance their sustainability efforts.
