Don’t let your refurbishment get you hot under the collar

When undertaking due diligence work, we often identify instances in which owners have carried out quality refurbishments that include foyers, floors and ceilings.

 

While this certainly does help with the building’s maintenance and appearance, the refurbishment often overlooks a critical part of the equation: the air conditioning unit.

 

Air conditioners are a critical resource for buildings everywhere.  Why is it then that they are so often overlooked? Many building owners do not consider the air conditioning unit to be particularly important in terms of refurbishment. Some owners do not even consider that air conditioning units would ever need to be refurbished.  This however, is certainly not the case.

 

For most buildings, the air conditioning units were installed when the building was constructed. In some cases, this is as many as thirty years ago. As such, these air conditioning systems were designed to suit conditions relevant to the times when the building was originally constructed. For older buildings, this means that the air conditioning was designed to cater for factors that we consider common today such as computers, longer working hours and work station clusters.

 

Why is this a problem? Computers and body temperature each affect the general air flow required within a building. Consider a 10 storey building with a central air conditioning unit. It is likely that over a period of years, the number of employees within the building would have increased; the required electricity would have significantly increased; and the hours of work would most likely also be significantly greater.

 

In this instance, the air conditioning unit will have to work significantly harder than it did when it was first installed.

 

This can lead to several problems due to the increased workload, including increased maintenance due to, or to prevent failure, and increased running costs.

 

Effective, efficient air conditioning systems are a major consideration for employees and therefore benefits. So, a building owner must consider this issue when allocating funds for refurbishment, in order to achieve an optimal return on investment.
