Temporary structure design helps with heat loss and contamination

posted on

Insulated temporary buildings protect against heat loss through the roof and walls by using lightweight insulating polyurethane foam.  This substance keeps in heat generated by the workforce, machinery and also heating equipment that may be used when the ambient temperature is very cold.  For temporary buildings that are open to the public, or customers, insulation is very important as a cold environment will put people off from making a purchase and encourage them leave a lot more quickly than if they were comfortably warm.

Although insulated temporary buildings protect against most heat loss through their design and construction, there is another way in which temporary buildings can make use of the flexible nature of their design and construction to guard against heat loss, especially when it is important to keep as much heat in as possible.

Double doors for pedestrian entrances and exits effectively create an airlock between the interior of the building and the cold outside air.  Provided the distance between the two doors is far enough that one person cannot operate both at the same time, one door will always be closed against the elements (unless the building has a heavy footfall in and out and the doors are held open for a long period to let many people out at the same time).  An air lock in your insulated temporary building entrance does not have to be merely functional, putting down some nice carpet, some potted plants and information panels or artwork on the walls will make it feel like a plush entrance hall, inviting people in and out, instead of an extension tacked on to reduce heat loss and it will create a good impression on visitors at the same time.

The same concept can be used for buildings where access is available for large vehicles through roller doors.  A loading bay can be added to a building (or incorporated in the original design) with closed sides and an extra roller door.  The lorry then reverses into the bay extension through the open roller door, which is then closed before the second door into the warehouse or factory is opened.  This prevents heat from escaping directly into the outside world and also provides an extra layer of security against break-ins.  If a protruding bay is not suitable in certain spaces, or would block access to other parts of the site, it could be added inside the building, but this would take up a significant amount of space in the interior, which could seriously affect production and storage space.

It is not just heat loss that these double-door airlock systems protect against.  Autumnal leaf fall and dust blowing around in summer can cause contamination problems in factories and warehouses producing or stocking fragile or perishable goods, so by denying direct access from the outside to the interior it is possible to reduce the amount of undesirable matter entering the building, and it is very easy to clear this away from the outer door.  In a showroom, exhibition hall or other publicly accessible insulated temporary building leaves and other outside debris can create a bad impression, so by restricting the chances of this happening in the first place there will be less cleaning and a lower likelihood of the leaves blowing into the main spaces.

Although adding an extra door and more walls to your insulated temporary building may cost a little more initially, the cost savings over a year or two on the heating bill alone could pay for the extra outlay to begin with, and makes financial sense in the long term.
