Proper Ventilation of a Building

Proper ventilation in a building can be an effective measure for condensation control. The end use of the building must be the controlling ventilation design parameter, especially above drop ceiling areas. Ventilation system design should be done at the initial building design stage. Use of a design professional is strongly recommended to assure the best possible system.

CONDENSATION CAN BE MINIMIZED THROUGH CONSIDERATION OF CLIMATE, RELATIVE HUMIDITY AND THICKNESS OF INSULATION.

Heat Transfer

Effectively controlling temperature in a steel building requires insulation to be present along exterior walls and roof. When a temperature differential is present in an enclosed steel building, heat will work from warmer areas to colder areas until the temperature in the building has stabilized. At the point of thermal stabilization, the cooler (and heavier) air will be present at lower elevations and warmer air will be present at the roofline. The function of insulation is to help stabilize air temperature at more desirable levels. When it is hot outside, preventing heat from transferring into the building is the goal, and of course in the winter we want heat to remain inside.

Heat transfer occurs in three ways:

Conduction : Occurs in a solid or liquid when heat from one object is transferred by touch to another object. An example of this occurs when a pot on a stove will heat up by conductive heat transfer from an electric coil.

Convection : Occurs with the physical movement of air. There are two types of convectional heat movement. The first is natural, where hot air rises displacing the cold air and moving it down. The second type is forced or mechanical convection. This occurs when an object, like a fan, physically moves or "forces" the air to move.

Radiation : Occurs when an object is warmer or hotter than the air around it. For example, the sun, which is hotter than everything around it, radiates heat waves that travel through the air and is either absorbed by or reflected by the surface it comes in contact with.

Concealed Condensation

Concealed condensation is the most difficult to deal with and can be the most damaging to any kind of structure. This type of condensation may be controlled in metal buildings by the proper ventilation. Additional condensation control can be accomplished by venting the cold cavities of the walls and roof.

Steel Buildings vs. Conventional Construction

A great advantage of pre-engineered buildings is that they can be relocated if required. Since your building is shipped to you with a complete set of instructions, detailed engineering drawings and a shipping list, you can erect you steel building without consulting a construction company. This also means that should you someday decide to relocate, you can take down your building and erect it elsewhere.

Adding partition walls in a steel building allows one building to be a meeting room, or office and storage facility and another to be a restaurant. Building with steel gives you the ultimate in design flexibility. You can either own one outright or purchase a steel building to rent to others. Your one time cost is regained sooner rather than later when you rent it as mini storage or public meeting space. Steel buildings can be designed with a almost unlimited amount of options.

If you have a need for a new building, don't make a decision until you have explored your options with a qualified steel building manufacturer. The Steel Building Network has reviewed a wide range of manufacturers, suppliers and building industry professionals, and we know that no matter what your intended use, there is steel building system to suit your needs. Getting I contact with the right company to get your questions answered is the first step in having your building needs met.

Temperature Control

Your geographic area will, to a great extent, influence the type of insulation that will provide the best performance. If you live in a mild climate and your building is used for farm equipment storage, insulation may not be necessary. If you are planning to have employees working in a building, you should probably install insulation, particularly in areas where temperatures are extreme. Energy savings will quickly pay for insulation if the building will be climate controlled.
