Building Enclosure Design Guidelines for Cold Storage Facilities

Cold Storage facilities can be considered typical, and the heated building becomes internal. Rather than designing to keep the heat in cold weather, but designed to keep it warm.

Although typical heated buildings experience condensation in cold weather due to humid air penetration, summer air penetration is a major concern for refrigerated buildings. Due to the buoyancy of warm air caused by the buildup effect of the building, the negative pressure is generally caused by the lower level of the building and the higher level of positive pressure.

In refrigerated buildings, the stacking effect is reversed. The colder, more dense air tends to "land", resulting in higher levels of negative pressure and lower levels of positive pressure. The moisture-related damage to refrigerated buildings may vary due to small external or internal staining, and the building's shells are completely defective, including structural damage to the floor concrete slab.

Designing independent refrigerated buildings requires designers to think - the warm side is now cold; cold air is cooled instead of hot air rising; the main objective of the closure is to keep the warm air in the winter and summer. Failure to follow these general guidelines may lead to various condensation problems.

Outside walls and roof insulation will lead to cold outside the building. The consequences of insufficient insulation can be used from increased energy to condensation or even frost on the external surface. It is not a problem to use a continuous insulating plate as an external wall or as a part of these walls.

However, in hot, humid climates, even through the insulation of the fastener will lead to external condensation and possible microbial / algae growth or external surface corrosion / discoloration. The most effective closure of a building depends to a large extent on the external climate.
