Interview: How to save energy in your company?

Publié le 01 octobre 2024 - Directorate for Legal and Administrative Information (Prime Minister)

For this 3rd issue of Meeting with, we went to meet Priscille JULIEN, Energy Advisor to the Gard Chamber of Commerce and Industry (CCI). With her, we discussed the possibility of energy savings within her company.

“I help company leaders prioritize action, first the sobriety (remove unnecessary), then effectiveness (act to gain) and finally renewable energies (Empowering to be sustainable). This path allows you to reduce energy consumption, a prerequisite for developing renewable energy that is scaled to the real need of its company.’

Priscille JULIEN, energy advisor at the CCI du Gard

When can a Head of company turn to the ICC Energy Advisor?

I accompany leaders at different stages of their thinking.

Among the solicitations of companies are:

  • the emergency situation to reduce the energy bill: i analyze the bill in detail with the head of company to see whether it is an overconsumption, poor management or poor negotiation of the contract. I then help him find solutions;
  • companies wishing to control their energy costs : I identify the different consumption items and their optimization potential to help the manager make the relevant investment choices;
  • companies wishing to renewable energy encouraged by new legal obligations for certain sites ;
  • industrial companies wishing to to form an energy reference to increase their mastery of the energy issue.

What are your main accompaniments?

I am introducing into the company sobriety reflexes as a first source of savings on the bill. For example, instead of running reversible air conditioning throughout the night, it is better to have a programmable system with a clock so that the temperature is adequate in the morning when workers arrive. Checking off-peak consumption to detect unnecessary consumption is also essential.

On energy efficiency, I speak to two audiences:
  • industrial companies, which may benefit from energy survey to quantify the percentage of each use (compressed air, cold, air conditioning and heating, process, lighting). This diagnosis allows me to detect the most effective and quickly profitable actions;
  • tertiary companies (small shops, tourist establishments, offices...) who wish to energy renovate a building of less than 1,000 m². I am accompanying them for:
    • make a diagnosis of the work to be carried out (walls, windows, or roof)
    • prioritize investments (insulate well before you want to air-condition);
    • identify the sources of financing possible as the energy retrofit tax credit or energy savings certificates, filed after work and purchased by energy suppliers.
With regard to renewable energy, we support companies in:
  • theopportunity analysis of photovoltaics, for roofs of more than 200 m²: i establish surface recommendations and estimate the time of return on investment. I also give them the points of vigilance to discuss with their provider: waterproofing, structure, fire safety, insurance, city planning rules. Any company that has enough land and consumes energy on the spot should ask about photovoltaics. The return on investment is often between 7 and 9 years.
  • the change in their method of heating : The Mission Chaleur Renewable (financed by Ademe, the Region and the European Union) supports them technically to switch from oil or gas to wood, solar or geothermal heating.

Do you have an example of someone being accompanied?

I recently joined a company that distributes magazines through a logistics platform. The leader wanted to analyze the possibility of putting photovoltaics on the roof.

The photovoltaic opportunity analysis we carried out made it possible to identify precisely the company potential, to analyze the relevance of coupling vehicle charging stations to optimize the self-consumption rate. This promotes a better time to return on investment. This project allows the manager to anticipate regulation. Indeed, by 2028, it will have to implement a minimum of 30% solar coverage on the roof of its building with a 500 m² footprint.

We took the opportunity to analyze together the electricity contract and the consumption reduction paths. The company is on the right track!
