Per office: does the label C requirement apply? Label, justification and exemptions recorded Ready for an inspection query

Custom energy label monitor for an office portfolio

Appfront builds energy label monitors for office owners and managers. For each building, the software checks whether the label C obligation applies, based on usage functions and floor areas. It tracks the registered label and its validity, records exemptions with their supporting evidence, plans measures for buildings that don't comply, and keeps a file per building ready if the environmental service or municipality asks for it. This page covers offices only. For energy labels across a mixed portfolio, see our separate page.

What is a label monitor for an office portfolio?

Since 2023, office buildings must generally have at least energy label C to be used as offices. Whether the requirement applies to a building depends on its usage functions and floor areas, and there are exemptions, for example for listed buildings. Anyone with dozens or hundreds of office buildings needs to know, for each building, whether the requirement applies, whether the label complies, and how that is justified. A label monitor keeps track of this.

In many portfolios, the label C requirement was once checked in a project, with a spreadsheet as the result. Since then, a building has partly been let as housing, a label has expired, or an exemption was never recorded. The environmental service can enforce, and when asked, the owner must show why a building complies or why the requirement does not apply. Then everything has to be worked out again.

We build custom solutions because the monitor must fit your portfolio: how many offices, whether they are mixed-use or not, what data you hold on usage functions and floor areas, which advisers prepare labels, and how you plan measures. What applies to a specific building is determined with your adviser; the monitor records it and keeps it up to date. For energy labels across a whole mixed portfolio, see our page on label management.

Requirement applies

Per building, the usage functions and floor areas, and the recorded assessment of whether the label C requirement applies.

Building complies

The registered label with class and validity alongside the requirement, and exemptions with their justification.

File for inspection

Per building, the assessment, label, exemption or measures, ready for an query from the environmental service.

How we build your label monitor for an office portfolio

We start with your offices: how many there are, what data you hold on use and area, and when the label C requirement was last checked.

1
Map the offices

Your office buildings, usage functions and floor areas, labels, exemptions and advisers.

2
Assessment per building

For each building, recorded whether the requirement applies, with the data and justification.

3
Labels and exemptions

Registered labels with validity, exemptions with evidence, and buildings below the standard.

4
Measures and reporting

Measures and timeline, notifications on expiry and changes of use, reporting, and ongoing management.

What an office portfolio label monitor does in practice

The components below feature in almost every office portfolio. Which ones you need depends on the number of buildings.

Buildings

Office buildings with use functions and floor areas from the BAG and your administration.

Assessment

Per building, whether the label C obligation applies, with justification and date.

Labels

Registered label with class, registration date and validity.

Exemptions

Exemptions with the grounds and evidence, such as a listed building status.

Measures

For buildings below the standard, the measures, the timeline and the expected label.

Notifications

A notification when a label is about to expire or a change of use affects the assessment.

Who we build an office portfolio label monitor for

The monitor is intended for those who own or manage multiple office buildings.

Property investors

Offices within an investment portfolio. The assessment and the file are the core.

Owners of mixed-use buildings

Offices alongside homes or shops. The use functions matter most.

Property managers

Offices with multiple owners. Reporting per owner is what is needed.

Municipalities

Owned office premises and a model role. The measures and timeline are the core.

Why choose Appfront for your office portfolio label monitor?

An office that does not meet the obligation generally may not be used as an office. We build on that: knowing per building whether the obligation applies, a label that complies, and a file that is ready to go.

Assessment on record

For each building, it is recorded why the obligation does or does not apply. No need to work it out again when a question arises.

Changes noticed

A change of use or an expiring label triggers a notification, so the assessment stays current.

Ready for supervision

The file for each building is ready should the regional environmental service ask for it.

Security and privacy for an office portfolio label monitor

The monitor holds data on buildings, labels, tenants and plans. Access is set up by role: the manager sees their own portfolio, and an adviser only the buildings they are engaged on.

The monitor runs in a European data centre, with encrypted storage and daily back-ups.

Frequently asked questions about an office portfolio label monitor

Questions that office owners ask before getting started.

It records, per office building, whether the label C obligation applies, which label the building holds and how long it remains valid, which exemptions apply and which measures are needed, and builds a file per building for supervision.

Since 2023, office buildings generally must hold at least energy label C in order to be used as an office. Whether the obligation applies to a building depends, among other things, on its use functions and floor areas, and there are exemptions. You establish what applies to your buildings with your adviser.

Label management covers the energy labels of a whole portfolio, including homes, shops and offices. This monitor concerns only offices and whether the label C obligation applies and is complied with, building by building.

From the BAG register and your own records. Where they differ, the monitor flags it so it can be investigated.

Per building, with the basis for the exception and the evidence, such as a monument status or a decision, so it can be shown when questioned.

The monitor records measures with the expected label that your adviser calculates, along with the schedule. The calculation itself is carried out by a certified adviser.

The public register shows the label per address. It does not show whether the obligation applies, which exemption is in place or which measures are planned. That is what the monitor is for.
