OPTIMIZING HEAT PUMP INTEGRATION FOR THE DECARBONIZATION OF DISTRICT HEATING IN VELIKA GORICA - META BUILD
The decarbonization of district heating systems is crucial for achieving Europe’s climate goals, particularly in urban areas. As part of the European Union-funded META BUILD project, Velika Gorica, Croatia, is transforming its district heating network by integrating renewable energy sources, with a strong focus on heat pump technology. The city aims to reduce carbon dioxide emissions by 40 percent by 2030 through the adoption of advanced energy-efficient solutions.
A comprehensive analysis is being conducted to determine the most suitable heat pump technology, evaluating water-to-water, ground-to-water, and air-to-water systems based on cost-effectiveness, efficiency, and integration potential. These technologies will replace fossil fuel-based heating, supported by photovoltaic thermal systems and thermal energy storage. Additionally, energy efficiency improvements, such as enhanced building insulation and smart controls, will optimize system performance and minimize heat losses.
By combining innovative heat pump applications with digital optimization tools, the project ensures real-time performance monitoring and operational flexibility. The findings from Velika Gorica will serve as a model for other European cities seeking sustainable district heating solutions. META BUILD’s approach supports the European Union’s climate and energy objectives, demonstrating a scalable pathway for low-carbon urban energy systems.

POREDBENA ISKUSTVA U REGULACIJI TEHNOLOGIJE POLUSAMOVOZEĆIH SUSTAVA U MOTORNIM VOZILIMA
Valja izložiti poredbeni modeli regulacije korištenja naprednih sustava za ispomoć u vožnji motornih vozila te sustava za automatiziranu vožnju motornih vozila. Naglasak je pri tome na američkim i europskim iskustvima u vezi uvođenja i primjene tehnologije na trećoj i četvrtoj razini autonomije (SAE klasifikacija).
