Unlike an EPC (Energy Performance Certificate), which results in a certification, an energy audit should be conducted at least every four years. For larger enterprises with consumption exceeding 2.5 GWh, energy audits are mandatory every four years (Energy Audits in Large Enterprises – NVE).
An energy audit should provide a detailed overview of the building’s energy consumption based on historical data, including processes and logistics. The purpose of the report is to:
Offer advice to improve energy performance
Provide concrete recommendations based on financial calculations and payback periods
Share tips on co-financing, loans, and grants for investments
Several steps are involved in the energy audit process—some with and some without the use of Autility. Below is our suggested workflow for the steps where Autility is used.
1 - Digitize the building
Start by creating a digital twin of the building in Autility, if you haven’t already.
This can be done using a BIM model or floor plans. The result is a digital, operations-oriented copy of the building. You’ll get a clear overview of all floors and rooms, where you can register assets, work orders, and incidents.

2 - Conduct a site inspection
During the site visit, use the digital twin in Autility—accessible via your mobile device.
Register and visualize doors, windows, and technical systems such as ventilation, heating, cooling, and lighting as you walk through the building. By placing these elements correctly in the twin, you’ll maintain full control over location and related data.
Take photos of systems, labels, and other useful information. Let our AI support analyze and enrich the data—saving you time on manual documentation.
You can also link measurement data and consumption figures, and register incidents and actions directly during the inspection. This simplifies analysis and report creation, while also making daily operations, maintenance, and management more accessible.
If you're short on time, you can complete the process back at the office. The app and web versions are fully synchronized.

3 - Post-processing after inspection
Complete the registration from the inspection in the web version of Autility.
Documentation can be enriched with additional data and images.
This step includes identifying opportunities to utilize surplus energy, such as excess heat from cooling systems, or optimizing existing technical installations.
This work can be done by you as a professional—or delegated to our Backoffice team.

4 - Link energy work measures
Energy measures are linked directly to relevant building components. You can register multiple incidents, recommended work orderes, costs, and cost distribution.
Our AI support makes this process fast, accurate, and efficient.

5 - Condition report and further reporting/collaboration
A structured condition report is automatically generated in the user interface. It can be used as-is or serve as the foundation for a more comprehensive final report for the client.
If you need to export data for further processing in other systems, this can be done easily.
Feel free to share information with suppliers, communicate internally, or invite clients to view the building.
