How can natural ventilation be beneficial?

Natural ventilation plays a crucial role in enhancing indoor environmental quality and energy efficiency. One of its primary benefits is its ability to help regulate indoor temperatures. By allowing outdoor air to flow through living spaces, natural ventilation can cool the interior during warmer months, which reduces the need for mechanical cooling systems like air conditioning. This not only leads to lower energy consumption and costs but also contributes to a more sustainable living environment.

Furthermore, natural ventilation can improve indoor air quality by facilitating the exchange of stale indoor air with fresher outdoor air, thereby reducing pollutants and allergens. This aspect, combined with the energy-saving potential, makes it a favored option in building design and operation.

The other choices suggest outcomes that either contribute negatively to indoor conditions or do not accurately represent the benefits of natural ventilation, highlighting why regulating indoor temperatures and reducing reliance on mechanical systems stands out as the most valid benefit.
