Dynamic building physics for projects that must be right the first time
Lamit Oy has modelled building physics since 1996. Instead of static monthly estimates, we solve the full 8,760-hour energy balance — and turn that one model into permit documentation, correctly sized equipment and city-scale district energy models.

BIM-based energy modeling and 8,760-hour simulation
The architect’s IFC model becomes a physics model. One calculation chain produces the E-value, the energy certificate, the LCA climate report and the building product catalogue for the permit.
District energyDistrict energy optimization and city-scale digital twins
A+Nodes connects building-level physics to the network: district heating return temperature, simultaneous peak loads and storage sizing solved hour by hour.
Value chainDigital twin value chain — BIM as a byproduct
Digitalising the existing building stock is the bottleneck of every energy transition. Our chain produces the BIM model as a byproduct of the energy calculation.

One model, not three parallel documents
Energy assessments are usually produced after the design is frozen, which turns simulation into a stamp rather than a design tool. Our process runs the other way round: the physics model is built first, and every document is derived from it.
One model
The IFC/BIM model — or a model rebuilt from 2D drawings — carries geometry, materials and volumes.
One physics engine
A-Nodes solves the EN ISO 52016-1 5R1C state-space matrix for all 8,760 hours of the year.
One documentation set
The same model yields the permit documents, equipment sizing and the digital twin of the building.
