Cédrus Liget Residential Park in Szeged

Oct 03, 2023

Leading the Way in Sustainable Living! The Cédrus Liget Residential Park in Szeged, Hungary.

We are thrilled to share the prodigious success of the Cédrus Liget (Cedar Grove) Residential Park in Szeged, Hungary, an exclusive development setting the bar for sustainable living and energy innovation. This forward-thinking project offers approximately 600 residences, commercial and public buildings, all within a brownfield setting.

The heart of this project lies in its revolutionary energy infrastructure – the largest geothermal district heating system in Europe. Sourcing renewable and sustainable thermal waters from nearly 2,000 meters below the surface, this system is a testament to the city’s commitment to a greener future. The thermal waters are transported through an extensive city-spanning network of over 32km, linking more than 215km of existing underground pipework.

One of the most significant challenges faced by our dedicated design team at Ventosus Kft. was charting a route for this extensive pipeline within a city already brimming with operational infrastructure. This was especially critical to ensure seamless connections between the residential park and vital public institutions. We achieved this through strategic collaboration with industry leaders like Raccorderie Metalliche Spa for pressed steel pipework, GRUNDFOS for cutting-edge pumps, IMI Hydronic Engineering for smart valves, Wavin for PE-HD pipes, Aereco Group for air inlets, Troges Air Technik for exhaust fans, F2 Komplex for fan coils, ista for submeters, PAW GmbH & Co. KG for domestic hot water modules, KE KELIT for multilayer pipes, Pipelife International for underfloor heating manifolds, and HL Hutterer & Lechner GmbH for drains, among several other partner organizations.

To ensure uninterrupted service during maintenance and special peak usage periods, an additional 3 MW Viessmann boiler is housed within the residential park, offering emergency backup and supplemental energy support.

In addition to this, Ventosus seamlessly incorporated Panasonic Heating & Cooling Solutions Europe air-to-water heat pumps boasting a combined output of 4.3 MW. This integration efficiently addresses cooling requirements, leading to superior energy efficiency, sustainability, and optimized and comfortable environments for the residents.

The impact of this geothermal project is already tangible. Szeged has witnessed substantial savings, running into millions of dollars, by reducing its dependency on fossil fuels. Moreover, this has resulted in a significant reduction in the city’s carbon footprint, aligning with global sustainability goals. Equally, the residents and businesses are shielded from soaring energy costs, providing stability and security in an unpredictable energy market.

This success story highlights the power of sustainable solutions, reinforcing our collective responsibility to adopt eco-friendly practices and embrace renewable energy sources. Let’s strive for a cleaner, greener future!
