According to Brazil's climate characteristics and building needs, the areas suitable for installing ERV (energy recovery ventilation) systems are mainly concentrated in the following types of areas:

1. High humidity tropical areas

Amazon rainforest and northern coastal cities: such as Manaus and Belém, which have high temperature and high humidity all year round. ERV can effectively balance indoor and outdoor humidity,

prevent mold growth and reduce dehumidification energy consumption.

Northeastern coastal areas: such as Salvador and Recife, where sea breezes bring high-salt humid air, ERV can reduce the damage of corrosive moisture to indoor equipment when introducing fresh air.

2. Densely populated metropolitan areas

São Paulo metropolitan area: As a commercial center, high-rise buildings are densely populated and air pollution is high. ERV can improve indoor air quality with high-efficiency filtration systems, 

especially for office buildings, shopping malls and residences.

Rio de Janeiro: With a hot and humid climate and a high-density population, ERV has significant advantages in hotels, hospitals and other places with high air quality requirements, 

and can stably maintain comfortable temperature and humidity.

3. Inland plateaus with large temperature differences between day and night

Minas Gerais: For example, Belo Horizonte, the plateau climate causes a significant temperature difference between day and night. 

The heat recovery function of ERV can reduce heating/cooling energy consumption and is suitable for residences and schools.

Southern high-altitude cities: For example, Florianopolis in Santa Catarina, which is wet and cold in winter and cool in summer, ERV can efficiently recover energy to reduce the heating burden.

4. Industrial and green building project areas

Industrial areas in Bahia: BYD and other companies promote green manufacturing (), and new factories give priority to the use of ERV systems to achieve energy-saving ventilation.

Sustainable certified buildings: For example, LEED certification projects in Sao Paulo require the use of energy recovery technology, and ERV becomes a key equipment for compliance.

Key installation recommendations

Standard adaptation: It is necessary to follow the Brazilian "Civil Building Ventilation System Installation Specifications" to ensure that the air inlet is away from 

pollution sources and the pipe insulation meets the standards.

System interlocking: In large buildings, ERV needs to be linked with air conditioning and CO₂ sensors to optimize energy consumption through variable air volume design.

Anti-corrosion treatment: Salt-resistant materials should be selected in coastal areas, and filter components should be maintained regularly.
