Los Angeles, a city with a Mediterranean climate, experiences hot, dry summers and mild, rainy winters. Ventilation systems are crucial for improving indoor air quality. 

The following are recommended locations and technologies suitable for installing ERV (Energy Recovery Ventilation) systems:

1. Residential Buildings

Old Residential Renovation

Some older buildings in Los Angeles lack adequate ventilation, which can lead to the accumulation of pollutants like formaldehyde. ERV systems offer efficient air exchange and energy recovery,

making them particularly suitable for families with asthma.

New Construction with High Energy Efficiency Requirements

Combining rooftop turbine ventilation (unpowered exhaust) with ERV can reduce summer air conditioning energy consumption.

2. Commercial and Public Facilities

Schools and Office Buildings

The Los Angeles Unified School District needs to increase ventilation following the wildfires. ERV systems can filter out toxic particles and maintain a balanced temperature and humidity.

Healthcare Facilities

Hospitals have stringent air quality requirements, and ERV systems can effectively control the spread of pathogens.

3. Technical Compatibility Recommendations

Climate Compatibility: Humidity control is a priority in Los Angeles' semi-arid climate (378 mm annual precipitation). Geographical Limitations: The basin-like terrain can easily lead to air stagnation, 

so duct planning is recommended to enhance ventilation efficiency.

Policy Support: Consider California energy conservation regulations and select Energy Star-certified ERV equipment for subsidies.

4. Alternative Solutions

Natural Ventilation Optimization: Utilize cool air from nearby waterfalls (such as Eaton Canyon) to assist with ventilation.

Smart Management: Utilize a ventilation equipment management system similar to that used in Jing'an District to monitor operating status in real time.

Note: Specific installation requires an assessment of the building structure and local climate data. Consulting with a professional HVAC engineer is recommended.
