Everything before the calculation and after it

Termavia collects and checks the data for a regulatory document, hands the calculation to a recognised procedure and measures the result after the works. The official methodology and the technician's signature stay exactly where the law puts them

Property record

Every value shows where it came from

One cadastral reference starts the whole scenario. The platform queries the public sources in parallel, brings the answers to one schema and builds a record the technician can read at a glance

  1. Reference in
    The user enters a 20-character cadastral reference
  2. Parallel queries
    Connectors ask the Cadastre, the regional register, the cartographic institute and AEMET at the same time
  3. Normalisation
    Built area becomes useful floor area, the outline and roof come from imagery, and the sources are checked against each other
  4. The record
    Each parameter gets a value, a source tag and a confidence level
  5. The site checklist
    Whatever the registers could not confirm becomes the list for the visit

An existing building book, today and on the platform

The longest of the four documents, prepared for one residential building. The site visit stays, and the desk work around it shrinks

Calibration and outcomes

Two calculation loops, kept apart on purpose

The registered document is computed by the official methodology. The savings forecast comes from a model tuned to how the building actually uses energy

Regulatory loop

The document the law requires

Purpose
The indicators of the registered document
Computed by
A recognised procedure from the state register
Runs on
The technician's workstation
Input
The normative scenario of use
Result
Printed form and electronic report in XML 3.0
Responsibility
The technician who signs the document

Advisory loop

The forecast you can check later

Purpose
Calibrated forecast, confidence interval and scenarios of measures
Computed by
Termavia's hourly building model following the logic of ISO 52016, with Bayesian calibration
Runs on
The platform server
Input
Actual hourly consumption and actual weather over at least 12 months
Result
Calibrated consumption, interval and savings for each scenario
Responsibility
The platform, which publishes its own accuracy

Access to consumption data

The path depends on the heating system

Calibration starts only after the holder of the supply point authorises access. Choose a case to see what it takes

boiler 1 point 8 of 24 flats by hand

Central system

One authorisation for the building

A single supply point held by the community of owners, so one resolution of the general meeting is enough

What it means

The shortest path to a first calibrated result

A series of at least 12 months is needed. Authorisation can be withdrawn for each supply point at any time, and processing then stops

Outcome measurement

From baseline to verified savings

  1. Baseline before the works

    At least 12 months of actual consumption and weather

  2. The works

    Measures carried out according to the scenario the owner chose

  3. Normalisation

    Consumption after the works is adjusted for the actual weather of the period

  4. Verified savings

    The measured result with a confidence interval, set against the forecast

A second loop for comfort

Hours outside the thermal comfort zone, humidity and air quality, captured by off-the-shelf sensors

Getting connected

A browser for the office, one small module for the signature

Administrators and institutional holders work in the browser only. Practices add a local module on the computer of each technician who signs

Web workspace

Runs in the browser with nothing to install: properties, drafts, portfolio, signature requests and plan limits

Local calculation module

Sits next to the recognised procedure, launches the run in one action and returns the result. The tool itself is not modified

Connecting a practice

  1. Organisation accountApply, create the account and choose a plan
  2. TeamInvite staff by email and give each a role
  3. Local moduleInstall it in 15 to 20 minutes and pair it with a one-time code valid for 15 minutes
  4. SignatureConnect the qualified electronic certificate. The private key never leaves the card or the cloud service
  5. AcceptanceRun a test property through six checks, then start on real work

No visit from a platform specialist is needed
