Do you want to quickly reduce the consumption of your buildings? An operational audit of your building is the solution.
This “light” audit carried out by our energy managers makes it possible to identify actions to improve the operation of your equipment (heating, air conditioning, lighting, etc.) with a short ROI.
How to improve the energy performance of a building?
The energy performance of a building depends on 3 factors:
- Its envelope
This concerns the structure of the building (construction materials used, type of single or double glazing opening, type of insulation, etc.). A poorly insulated building will consume more in terms of heating but also in summer to cool it.
- Its equipment
These are the energy production terminals used in the building to heat it (boiler or heat pump), light it, ventilate it (air handling unit) or even air-condition it.
For example, LED bulbs consume 80% less electricity compared to conventional bulbs.
- Its uses
This concerns the way in which building occupants use equipment to heat, light or cool the room. Heating a room to 20°C instead of 19°C represents 7% more consumption (Source Ademe)
How to reduce your energy consumption?
To reduce the energy consumption of your building, it is therefore possible to act on the 3 levels (envelope, equipment and uses) but this requires more or less time or financial investment:
- To improve the envelope of a building, it is therefore necessary to carry out major thermal renovation work, by insulating the roof or replacing the windows for example.
- To improve the energy performance of the equipment in your buildings, you must improve its operation by, for example, applying a night reduction on the heating thermostat or by centrally controlling your equipment with Technical Building Management (BMS).
- To adopt more sober uses, for example, it is necessary to encourage occupants to reduce the heating setpoint temperature or, for example, not to turn on the air conditioning below 26°C.
Act on operations thanks to the operations audit
To quickly reduce your consumption, without major investments, the best thing is to improve the operation of your equipment and the uses made of it by the occupants.
How to prioritize actions? Thanks to an operating audit carried out by our expert energy managers. This study allows you to review the operation of your building:
- Analysis of consumption month after month by type of fluid (electricity/gas)
- Analysis of the load curve to identify whether, for example, it is necessary to review the subscribed power depending on the number of connected devices
- Analysis of data provided by connected room sensors relating to temperature, humidity, brightness and this according to the seasons
Based on this study, energy managers recommend energy performance actions to improve the operation of the equipment concerned and their uses: for example reducing the set temperature for heating or air conditioning. Or turn off light sources during the day in unoccupied areas of the building or when there is sufficient natural light.
