The following areas in Romania are suitable for installing ERV (energy recovery ventilation) systems, combined with climate characteristics, building demand and market dynamics.

I. Climate-driven areas

‌Southern and eastern lowlands (such as the area around Bucharest and Giurgiu County):

The average temperature in summer is 38°C, and the winter is cold (average -3°C). The ERV system can effectively balance the temperature difference between indoor and outdoor, 

reduce energy consumption, and is suitable for residential and commercial buildings.

‌Transylvanian Plateau‌:

The winter is cold for a long time, and buildings around new solar parks (such as Eurowind Energy's 60.2 MW project) may need to be equipped with energy-saving ventilation facilities.

II. Economic and infrastructure active areas

‌Bucharest (capital area):

As an economic center, new residential and commercial projects are densely populated, and the 65 MW photovoltaic park in Prahova County is about to be put into operation, and there is 

a strong demand for energy-saving buildings.

‌Timisoara‌:

With developed industry and commerce, local companies such as SC Octali Srl have deployed small-scale photovoltaic systems to promote the application of green building technologies.

3. Policy support areas

‌Galati County (Kuka Township):

The construction of Green Breeze wind farm drives regional energy transformation. Combined with Romania's grid access and installation authorization specifications for new energy projects, 

supporting buildings may give priority to the use of high-efficiency ventilation systems.

‌Oradea‌:

EBM-Pat invested 30 million euros to build a factory. The upgrading of manufacturing industry may drive the demand for ERV systems in the surrounding construction industry.

4. Applicable scenario suggestions

‌New residential area‌: Developers who focus on energy efficiency can choose ERV systems to meet energy-saving standards.

‌Commercial complex‌: Combined with Romania's high credit card penetration rate and strong spending power, high-end commercial spaces have a significant demand for comfort.

‌Industrial supporting buildings‌: Such as photovoltaic and wind farm surrounding control centers, a stable ventilation environment is required.
