A venting system for a temporary shelter that includes one or more vents that are positioned in the exterior shell of the temporary shelter. Each of the one or more vents may include a membrane that is moisture vapor transmissive and resistant to liquid penetration. The membrane may have a moisture vapor transmissive rate of at least 4,000 g/m²/day. The membrane may be expanded polytetrafluoroethylene. The one or more vents may have a size such that there is approximately 4 m² of vent surface area in the exterior shell of the temporary shelter per 20 m³ of interior space within the temporary shelter.
