Livestock climate, energy & emission software

Design the ventilation. Document the emissions.

StaldVent simulates barn climate, energy consumption and ammonia and odour emissions – hour by hour, all year round. Built on a research foundation that has been the industry reference since 1990.

✓ Built on Danish research since 1990 · ✓ Used by consultants, manufacturers and universities in 10+ countries

Cross-section of a pig house with ventilation Air enters through wall inlets, passes the animal zone and is extracted through roof stacks. Data labels show airflow, negative pressure, barn temperature and ammonia from the slurry channel. 20.0 °C NH₃ 23,500 m³/h −15 Pa
Inlet → animal zone → exhaust: the entire system simulated with local climate data

Capabilities

One program. The entire climate system of the barn.

Emission documentation

Regulation is moving to emissions. Your calculations should get there first.

Across Europe, livestock permits increasingly hinge on documented ammonia and odour emissions and the proven effect of abatement technology. StaldVent was developed in Denmark – where emission-based permitting has been reality for years – and provided the calculation basis behind the Danish guidelines for partial air cleaning. Wherever your projects are, the documentation logic is the same: verifiable, hour-by-hour simulation instead of brochure figures.

  • Ammonia and odour emission across the full year

  • Cleaning efficiency for chemical and biological air cleaners – including partial cleaning

  • Reports ready for the permit file
