SI 426 Compliance

SI 426 Compliance forms part of the Energy Efficiency Directive (EED) which by law requires large organisations to complete energy audits every four years.

Energy Efficiency Directive (EED)

The main prerogative of SI 426 Compliance and the EED is to ensure that large, energy-intensive organisations are at least making the minimum efforts required to improve energy efficiency.

This means meeting the minimum criteria for energy audits, outlined by the SEAI, every four years.

The Energy Efficiency Directive is Mandated by the SEAI

Minimum Criteria 

The minimum criteria for energy audits are outlined in full in this document.

In summary:

  1. Energy audits shall be based on four high-level principles – outlined in Section 4.1
  2. Energy audits shall allow detailed and validated calculations for the proposed measures to provide clear information on potential savings – outlined in Section 4.2
  3. The data used in energy audits shall be storable for historical analysis and tracking performance – outlined in

At Lawler Sustainability, we can work with your organisation to process these audits, highlighting opportunities to improve efficiency, and recommending measures that will not only ensure compliance but increase your company’s energy efficiency dramatically.
