Raising awareness of air-conditioning temperature settings

Why raise employees’ awareness of the right temperature setting? Air-conditioning consumption can vary enormously depending on how users behave. Here are some figures on the use of air conditioning: - Raising the air-conditioning temperature by 1° reduces the energy consumed by 5 to 10%. - Changing the air-conditioning thermostat setpoint from 22°C to 27°C halves air-conditioning consumption. - Switching on the air conditioning only when the outdoor temperature is above 30°C instead of 27°C divides annual air-conditioning consumption by 3. How can the use of air conditioning be optimised? To optimise air conditioning, the first step is to limit its use as much as possible. Before using air conditioning, passive cooling methods can be implemented. Here are some actions for sensible use: - Limit the temperature difference with the outdoors to a maximum of 4° with an indoor setpoint of at least 26°C. - Having the air conditioning maintained by a professional authorised to handle refrigerants ensures optimal operation of the installation. - Choose your air-conditioning system carefully. It is important not to buy equipment in a hurry: large performance differences exist between the various air conditioners on the market. A portable air conditioner consumes 2.5 times more than a reversible air conditioner such as a heat pump with an outdoor unit.
