Mozambique's climate is characterized by hot and humid weather, with abundant rainfall year-round and a wet season lasting nine months (September to May). 

Humidity is particularly high in the tropical north. This high temperature and humidity favor the use of ERV ventilation systems, as they efficiently recover energy, 

regulate indoor humidity, and reduce air conditioning energy consumption.

Specific suitable regions include:

Northern provinces (such as Cabo Delgado, Nampula, and Zambézia): These regions are characterized by high humidity and the high risk of malaria, 

indicating the prevalence of hot and humid conditions that foster mosquito breeding. ERV systems can significantly improve air quality in public buildings such as hospitals and schools.

Southern subtropical regions (such as those surrounding Maputo): Although the climate is slightly milder, the overall high temperature and humidity still support the energy-saving advantages of 

ERV systems, making them suitable for both commercial and residential projects.

Overall, ERV systems have potential throughout Mozambique, but priority is given to the high-humidity northern regions to maximize health and energy benefits.

Based on Mozambique's climate characteristics, energy structure, and current industrial development, its ventilation needs are analyzed as follows:

I. Climate-Driven Ventilation Needs

High Temperature and High Humidity Environment: The country experiences high temperatures and humidity year-round. The northern tropical regions (such as Cabo Delgado and Nampula provinces) 

experience a nine-month wet season, with significantly higher humidity levels. This promotes mosquito breeding and exacerbates the spread of malaria, necessitating an urgent need for 

building dehumidification and air purification.

Southern Subtropical Region: While southern regions like Maputo enjoy a milder climate, they still experience high temperatures and high humidity overall. Continuous ventilation is required to 

maintain indoor air quality and reduce air conditioning energy consumption.

II. Energy Supply Constraints on Ventilation Systems

Electricity Dependence on Hydropower: 81% of the country's electricity comes from hydropower, but actual developed capacity (2,488 MW) only accounts for 13.8% of the potential reserves (18,000 MW). 

The northern power grid is not yet fully connected, and power supply is unstable in some areas. Gas-fired Power Plant Development: With the acceleration of natural gas development (such as the Rovuma Basin gas fields), the installed capacity of gas-fired power plants has increased (such as the 232MW Aggreko and 175MW CTRG), providing more stable energy support for industrial ventilation systems.

III. Special Needs of Industrial and Resource Development

Ventilation Challenges of Natural Gas Projects:

The Koror FLNG project (the world's second-largest floating liquefied natural gas platform) in Area 4 of the Rovuma Basin requires an explosion-proof ventilation system to cope with 

the high humidity and highly corrosive environment of deepwater operations.

Armed conflict has delayed Total and ExxonMobil LNG projects, but existing facilities still need to maintain high industrial ventilation standards to ensure safe production.

Mining and Heavy Industry: Coal-fired power plants such as the 1,200MW Moatize project are planned for construction in the Tete coal mining area, requiring dust filtration and 

forced exhaust systems to prevent pollution.

IV. Rigid Demand in Public Health

Healthcare Institutions and Schools: In northern malaria-prone areas, public buildings require energy recovery ventilation (ERV) systems. 

These systems suppress pathogen transmission through humidity control and reduce air conditioning loads in high-humidity environments.
