Where in Alberta is an ERV ventilation system suitable?

ERV ventilation systems, or Energy Recovery Ventilation systems, are suitable for installation in areas with large temperature differences and requiring 

efficient ventilation. In Alberta, the following locations are particularly suitable for ERV ventilation systems:


- **Calgary:** As Alberta's largest city, Calgary experiences cold winters with temperatures dropping to -30°C and a dry climate with humidity typically 

below 30%. ERV ventilation systems can recover heat and moisture from exhausted air while introducing fresh air, reducing heat and humidity loss and 

maintaining a comfortable indoor temperature and humidity environment.

- **Edmonton:** Edmonton, the provincial capital, has a temperate continental climate with long, cold winters, averaging between -10°C and -20°C with 

extreme lows reaching -40°C, and short, warm summers. ERV ventilation systems help retain heat indoors during winter and pre-cool and pre-heat fresh air 

in summer, reducing the load on air conditioning systems and saving energy.

- **Red Deer:** Located between Calgary and Edmonton, Red Deer is a major city in central Alberta. Its climate is similar to the two cities mentioned above,

 with four distinct seasons, cold and snowy winters, and warm summers. Installing an ERV ventilation system can effectively improve indoor air quality 

while reducing energy waste caused by ventilation.

- **Lethbridge:** Located in southern Alberta, Lethbridge is relatively warm, but winters are still cold, and the region has a dry climate with low annual 

rainfall. ERV ventilation systems can recover heat and moisture while ventilating, maintaining indoor air comfort and are suitable for installation in 

various buildings such as residences and offices.
