Loriini

Sun studies from Archicad, for a NSW DA.

Solar access hours against the Apartment Design Guide, shadow diagrams, site and context analysis and the area calculation, drawn straight into your Archicad project as native sheets, fills and schedules. No export to another program, no hand-typed table.

Loriini's lorikeet
Prototype, not validated for submission. Loriini is for design-stage iteration. Its figures have not yet been validated against a reference implementation on a real project, and must not be used as a compliance figure in a DA submission. A DA submission rests on a consultant's report. This notice stays until the validation is done.
What it makes

The sheets a DA needs, inside the project they belong to.

Loriini is a Windows program and an Archicad 26 add-on. It reads the open project, works out the sun, and writes what it finds back into Archicad as the things Archicad already knows: Zone properties, fills, worksheets, 3D Documents, layouts.

Solar access, by apartment

Hours of direct sun on each apartment's living room windows and private open space on 21 June between 09:00 and 15:00, assessed against the NSW Apartment Design Guide's 2-hour and 3-hour criteria, written onto the Zones so the ADG table is a native Archicad schedule.

Pure astronomy from latitude, longitude and time. No weather file.

Shadow diagrams and shadow plans

The hourly shadows cast by the model, drawn as fills in the legend's own colours, with what stands and what the proposal adds told apart. Or the same hours as one 3D Document each, with Archicad's own vectorial shadows, on sheets by day.

Site and context analysis

Give it a NSW street address and it draws the context analysis, the site analysis and the summary of controls from open data: NSW cadastre, ePlanning, topography, Transport for NSW, OpenStreetMap, and inside the City of Sydney the council's own contours and trees. Each sheet credits the publishers whose data reached it.

The area calculation

GBA, GFA, FSR and the yield from the massing slabs, before there are any apartments, worked the way the office's own calculation does it. And a massing mode that reports the share of facade and ground reaching two hours of sun, the metric a massing optimisation maximises.

A reference image over the 3D window

Set a view up from the corner a photograph was taken at, or match an earlier rendering, by laying the picture over Archicad's 3D window while the view is adjusted under it.

Driven by an agent, if you like

Every study is also a tool an AI agent can run. Claude Desktop, Claude Code or any client of the Model Context Protocol starts Loriini.exe mcp and works the open project through it.

How it works

A folder, no administrator rights, three steps.

  1. Download the folder. It holds Loriini.exe, the add-on LoriiniAddOn_AC26_Win.apx, an install note and the licence.
  2. Put both files in one folder of your own, for instance Documents\Loriini\Add-Ons. The menu item looks for the program beside the add-on.
  3. In Archicad: Options › Add-On Manager, add that folder, restart. A Loriini menu appears, and starts the program.

The licence

A subscription is counted in seats: a seat is a computer that has used Loriini in the last fortnight. One key per practice, pasted once on each computer. Loriini checks in with the licence service by itself and works for a fortnight without a connection. A computer that stops using Loriini frees its seat after a fortnight, or at once with Loriini.exe licence --remove.

Needs

Windows 10 or 11, Archicad 26. Loriini talks to Archicad on the same computer; nothing about a project leaves it.

Price

Per seat, monthly or yearly.

Prices in Australian dollars, before tax. The number of seats is chosen at checkout and can be changed any time in the customer portal, along with the card.

A$75 a seat a month

For a practice that needs Loriini for one DA. Cancel any time; the subscription runs to the end of the month paid.

Subscribe monthly

Trying it first. A 14-day trial key needs no card: ask for one with the practice's name and the number of computers. The key arrives by email.

Paying by invoice. A practice that pays annual invoices by bank transfer can ask for an invoice instead.

The program asks for a licence key the first time it opens. Without one it still lists its rulesets and reads a model, and touches nothing. The same download serves a trial key and a subscription.
