Roles and responsibilities

Every LUX Certify report names two people: the one who requested the simulation (Begärd av) and the one who reviewed it (Granskad av). The report is only as reliable as the model it was computed from, so the two roles split the responsibility for the input and for the interpretation.

Requested by (Begärd av)​

The requester is the project's responsible architect — the person who runs LUX Live on the rooms and requests the certified simulation from Revit. They deliver all of the input, and are responsible for it:

  • Geometry — the model is complete and suitable for a daylight simulation: no holes in the envelope, every window has glazing, and the relevant surroundings (neighbouring buildings, balconies, overhangs, terrain) are modelled, since they decide how much sky each window sees.
  • Materials — each surface carries a correct material specification (reflectance for opaque surfaces, transmittance for glazing), following the material guidance.
  • Rooms — every living room (vistelserum) that the regulation covers is selected, and the rooms are grouped into the right apartments, since compliance is assessed per apartment.

If any of these is wrong the result is wrong, however carefully the simulation is run.

Reviewed by (Granskad av)​

The reviewer is the daylight specialist who checks the input before trusting the output, and who signs the interpretation:

  • Geometry check — the model has no holes, contains nothing that does not belong in the calculation (furniture, vegetation, temporary elements) and misses nothing that does (for example windows without glass).
  • Material check — materials look correctly assigned (no floor finish on a ceiling, no opaque material on a window).
  • Interpretation — reading the results, explaining marginal cases and writing the discussion and conclusion of the report.

Upskiller​

Upskiller is responsible for the calculation itself:

  • the simulation runs according to the selected standard with a validated method (see Simulation engine);
  • the input is reproduced unchanged, geometry and materials exactly as exported from Revit;
  • results and report are compiled correctly from that input.

Upskiller is not responsible for the correctness of the input or for the interpretation of the results. Given a correct model, the result is correct; given a wrong model, the result is wrong in the same way.

What the report is, and is not​

  • A basis, not an approval. The report is a basis (underlag) for the project's daylight assessment. It does not replace the building committee's (byggnadsnämnden) review.
  • A snapshot in time. The report describes the model as it was when the simulation was requested. If the model changes afterwards the report no longer applies; request a new simulation.
  • Drafts have no standing. An export marked UTKAST carries a watermark and a notice on the cover. Only the final version, reviewed and exported by the named reviewer, is valid.
  • Retention. Upskiller keeps the simulation (model, settings and results) for one year from the report date. After that only the exported PDF reports remain, and the client is responsible for archiving them.

In the report​

Both names are printed on the cover, and a short version of this page is set as a footnote at the bottom of the cover with a link here. The reviewer's name is editable when the report is exported; the requester's name comes from the account that requested the simulation.
