The tool for it
VICUS Buildings Beta
Dynamic building simulation with IFC, DXF and PDF import, multi-zone room balance and verification per DIN 4108-2.
with VICUS Buildings
Dynamic building simulation for energy consulting.
Where the monthly balance reaches its limits.
Energy demand, room temperatures and summer comfort hour by hour across the year – for the new-build design as well as for the renovation roadmap for existing stock.
Starting point
Where simulation helps
Energy consultants assess buildings energetically – from the new-build design to the renovation roadmap for existing stock. Where the monthly balance reaches its limits, dynamic building simulation delivers reliable statements.
- Retrofit variants Contrast insulation, glazing, shading and ventilation and quantify the effect of each measure.
- Solar gains and thermal mass Effects that can only be represented properly in a time-resolved calculation.
- Summer comfort Assess room temperatures and overheating, up to the verification per DIN 4108-2.
- Existing plans Take over IFC, DXF or PDF instead of redrawing the building.
Approach
From model to robust assessment
- Step 1 Capture the existing building or design Read geometry from IFC, DXF or PDF, or build it directly in the 3D environment. Components and usage profiles come from bundled databases – no duplicate entry.
- Step 2 Dynamic instead of monthly balance Simulate heating and cooling demand, room temperatures and solar gains hour by hour across a full year – instead of relying on lump-sum monthly values.
- Step 3 Compare variants Contrast insulation standard, glazing, shading and ventilation as variants and quantify the energy effect of each measure reliably.
- Step 4 Verification and reports Export results on energy demand and summer thermal protection as traceable, customisable reports for clients and approval.

Frequently asked questions
Which energy-consulting tasks is VICUS Buildings suited for?
VICUS Buildings is a dynamic building simulation for the energy assessment of individual buildings: heating and cooling demand, room temperatures, summer thermal protection and variant comparison for new builds and retrofits. The hourly calculation represents solar gains, thermal mass and ventilation physically correctly – more accurately than a monthly balance.
Do I need specialised scientific training for the simulation?
No. The software is designed for the everyday work of engineering and energy-consulting offices: 3D modelling follows familiar CAD workflows, and the databases provide preset components and usage profiles. Getting familiar with the simulation is enough – a research background is not required.
Can summer thermal protection be verified per DIN 4108-2?
Yes. The dynamic simulation determines overheating degree hours and thereby provides the verification under § 8.4 DIN 4108-2 – including the assessment of shading, thermal mass and night ventilation.
Can I compare retrofit variants?
Yes. Insulation standard, glazing, shading and ventilation concept can be contrasted as variants. Because the same geometry serves as the basis, the energy effect of each individual measure is directly comparable and can be documented transparently.
