Energy audits

Energy savings and Energy management

Energy audits require expertise …

Energy management becomes a major issue.

REDI supports you in your logics of saving and managing energy and carries out energy audits on parts of installations in order to:

  • comply with legal obligations
  • optimize energy consumption by calculating investment returns and obtaining energy saving certificates

Energy Law of June 26, 1998 (LEne):

In accordance with the LEne, cantons must enact provisions concerning large consumers. These are consumers, located on a consumption site, who have actual or foreseeable annual energy consumption greater than 5 GWh for heat and / or 0.5 GWh for electricity (art. 28c al. 1 LVLEne) .
The canton of Vaud has introduced articles on large consumers as part of the amendment to the energy law that entered into force on July 1, 2014.

For large consumers to meet legal obligations, an audit must be carried out. Experience shows that many of energy savings concern adjustment of technical installations or the production organization.

Audit of your installation

  • List the main utility networks (steam, hot water, chilled water, compressed air, vacuum, etc.).
  • Audit the main energy consuming equipment.

Evaluation of the efficiency of energy improvements

  • Immediate return on investment: generally a soft modification
  • Return on investment <2 years: our priority objective for our customers
  • Return on investment> 2 years: generally within the medium term criteria of our customers

Suggested improvements

  • Optimized current operation: set points, automation
  • Maintenance, logistics, revision of energy contracts …
  • Energy recovery via heat exchanger for preheating.
  • Investment in more efficient equipment: variable speed compressor, modulating burner, etc.
  • Energy meter implementation.
