Nebraska is generally suitable for ERV ventilation systems, especially in the following areas:
- **Eastern Region:** This region has a humid continental climate with relatively high annual rainfall, decreasing from 800 mm in the west to
about 350 mm in the southeast. Cities like Omaha and Lincoln experience high humidity in summer and some snowfall in winter. ERV ventilation
systems can recover heat and moisture during ventilation, preventing excessive heat loss from indoors in winter and reducing discomfort from humid
outdoor air entering in summer, maintaining a comfortable indoor temperature and humidity environment.

- **Western Region:** This region has a semi-arid continental grassland climate. Although rainfall is low, seasonal temperature variations are large.
Northwesterly winds from Canada can lower temperatures to -18°C in winter, while warm southwesterly winds can cause temperatures to soar to 32-38°C
in summer. Cities like Scotts Bluff can benefit from ERV ventilation systems, which can refresh the air without losing too much indoor heat or cooling,
ensuring indoor air quality while reducing the operating load on heating and cooling systems.
