What are the differences between natural and mechanical ventilation?

What are the differences between natural and mechanical ventilation?

Natural ventilation relies on wind and temperature differences to circulate air, while mechanical ventilation uses fans and ducts.

Which one is more energy-efficient?

Natural ventilation is generally more energy-efficient as it doesn't require electricity, but it depends on climate and building design.

Are there any downsides to natural ventilation?

Yes, natural ventilation can be less effective in extreme weather and may not provide adequate air quality in all situations.

What about the maintenance of mechanical systems?

Mechanical ventilation systems require regular maintenance, including filter changes and inspections, to ensure optimal performance.

Which system would you recommend for a residential building?

It depends on the location and design of the building. A combination of both systems often provides the best results.
