The ventilation maintenance of your schools and buildings – controlled and proven
equova is the owner-side maintenance platform for municipalities, public property owners and their administrators: you outsource the ventilation maintenance of your schools and buildings to contractors – and with equova you prove, for every installation, that the maintenance you paid for was carried out on every component, in an audit-proof way. This lets you fulfil your operator responsibility for healthy supply air without inspecting on site yourself: you see at a glance what is due, open or documented – across your entire portfolio.
A dozen school buildings, records scattered – and the responsibility stays with you
When the audit, the ESG report or an inspection comes around, the proof sits where you need it least: as a PDF in the contractor's inbox, as an invoice on a network drive, as an Excel concept on a folder that went stale with the last administrator. Across a dozen buildings with air-handling installations, there is no way to prove that the maintenance you paid for was really done on every component.
The responsibility is yours: under SWKI VA104-01 and VDI 6022, ventilation installations must be inspected for hygiene at regular intervals – every two years with humidification, every three without – and the responsibility lies with the operator, even when the work is outsourced to a contractor (haustechnik-hoch2.ch, gabrielrebsamen.ch, retrieved 2026-07-15). How often the paid-for maintenance falls short is shown by the 2021 TÜV building-law report: of 17,896 ventilation installations inspected, only 34.3% were free of defects (tuev-verband.de, ingenieur.de, retrieved 2026-07-15). That was a building-law inspection, not identical to the VDI 6022 hygiene inspection – but a clear signal of why a contract alone is not proof.
Portfolio control, audit-proof records, no missed due date
-
One dashboard across all properties. You see, per property and per installation, what is open, due, overdue or documented – from the single school building to the entire portfolio. equova generates the maintenance orders automatically from the maintenance concept, following the intervals of the SWKI guidelines, instead of you tracking due dates by hand.
-
A record for every component that stands up to an audit. For each maintenance step, equova requires a photo proof, assigned to exactly one component and order, with a checklist and a condition rating – captured in an audit-proof audit log that cannot be altered afterwards. For an audit, inspection or report you generate the proof report per installation, property or portfolio at the press of a button.
-
No due inspection slips by unnoticed. equova monitors every due date across all installations, keeps a due-date calendar and reminds you in good time – before an inspection becomes overdue and before anyone asks for it in an audit.
You set the target – several contractors bid on it
You define the scope in the maintenance concept and put it out as a tender to several contractors. The contractors submit their quote in a structured form, you compare price and scope side by side and award transparently – instead of having to trust a single firm.
After the award, equova sets the agreed costs against the invoiced ones: if the calculated amount deviates markedly from the agreed one, the deviation is highlighted and can trigger a notification. So you spot inflated invoices before they go through – a standard that public procurement demands anyway.
Data in the EU, proof in your hands
The data is held in the EU, and data protection follows GDPR and the Swiss DSG. You can export everything at any time – maintenance concept, proofs and QR labels as PDF and CSV; cancellable monthly, no lock-in. The proof stays with you, even if a contractor changes.
To be honest: equova is not a conformity seal. It does not guarantee compliance with SWKI VA104 or VDI 6022 and does not replace an expert inspection. Technical conformity remains the responsibility of the executing expert and of you as the operator – equova provides the structured proof and the overview with which you fulfil that responsibility in a demonstrable way.
