In Romania, ERV (Energy Recovery Ventilation) systems are mainly suitable for building environments that require efficient air exchange,

 especially in apartment buildings and industrialized areas.

‌Apartment Building Areas‌: ERV systems are particularly suitable for installation in apartment buildings because they are small in size, low in noise, and can 

effectively meet the demand for fresh air and recover energy to improve indoor air quality. For example, in urban areas in Romania such as Bucharest, where apartment 

buildings are densely populated, ERV systems can be widely deployed in residential areas. In addition, as the capital city, Bucharest has generally good air quality 

(such as low levels of pollutants such as PM2.5 as shown in data from May 2025), but ERV systems can still supplement fresh air supply in an energy-saving way.

‌Industrial Plants‌: Industrial scenes such as factory workshops and service areas also need reliable ventilation systems to manage air circulation and smoke exhaust. 

Although the search results do not directly mention ERV systems in industrial applications, industrial parks in Romania (such as the Aricestii Rahtivani Industrial Park north of Bucharest) 

already have similar ventilation facilities, and ERV systems can be integrated to optimize energy consumption and air quality.

In conclusion, Romania’s apartment-dense cities (such as Bucharest) and industrial bases are ideal locations for the installation of ERV systems, which can fully utilize their 

energy-saving and fresh air advantages.
