Proper ventilation is necessary in all buildings, which are extremely susceptible to condensation and heat transfer. Generally, hot or stale air will not exhaust through an opening into which wind can blow. Therefore, regular static ventilators , which allow outside wind to enter in the shed because of poor design or location on the roof, cannot be expected to exhaust because they back draft.
An efficient means of extracting warm and stale air is through roof mounted turbo ventilators, which create positive draft, removes hot gasses, obnoxious fumes, bad odour, enhances ventilation. Adequate low level provision for the entry of fresh air at ambient temperature should be provided.
