As blackouts continue to plague Pakistan, the government has turned off all air conditioning units at public offices, according to a report in the Guardian today. Despite temperatures of over 40C, the sanction was necessary to conserve power. Instead, the government has issued a new dress code for civil servants which states that moccasins and sandals must be worn without socks.

With the exception of some manufacturing and industrial processes, in most circumstances in the UK, air conditioning is seen as a nice to have, rather than a necessity. With research showing the detrimental impact on productivity when temperatures fall outside the โGoldilocksโ zone, this perception is changing. However, regardless of the application, every user can take steps to mitigate their energy consumption when using permanent or temporary air conditioning:
โข Donโt assume you need a really low temperature โ adjusting the thermostat by just a degree or two can make a difference to comfort levels.
โข Ensure the air conditioning unit is well maintained โ older models and those not adequately serviced will be more of a drain on power and quickly add to your fuel bill.
โข Choose a unit appropriate in size and output: over-specified units will also be a drain on energy.
โข Select a model with an automatic thermostat which should mean that units arenโt left on when cooling is not required.
The advantages of temporary air conditioning are that it can be deployed only when necessary, capital isnโt tied up in creating infrastructure, especially onerous in some old building which donโt lend themselves to hidden โbuilt-inโ services, and the most efficient and up to date kit can be used without major remedial works.
And of course, thereโs no risk of that most British of fashion โfaux pasโ; socks with sandals in the workplace.
