Portugal's demand for ERV ventilation systems is mainly concentrated in the following places:

‌New high-standard residential buildings‌

Since Portugal emphasizes improving building energy efficiency in its decarbonization strategy, energy storage projects and new building standards that 

need to be put into operation before 2025 may promote the application of ERV systems to balance air quality and energy efficiency in confined spaces

‌Industrial and environmental protection facilities‌

Portugal has leading technologies in flue gas recovery and sewage treatment. Such high-pollution or high-emission environments may require ERV systems 

to assist in exhaust gas treatment while reducing energy loss

‌Extreme climate areas‌

In areas affected by strong winds such as Madeira Airport, the ERV system can work with wind speed detection technology to optimize the balance of indoor 

and outdoor air pressure, reduce ventilation energy consumption and improve comfort

‌Public buildings and tourist facilities‌

High-density traffic areas in tourist destinations such as the Gold Coast require ERV systems to maintain indoor air quality to avoid excessive window openings 

that increase air conditioning energy consumption
