The program

The barn’s entire climate engineering in one program

StaldVent is a decision-support program for Windows that combines design, simulation and documentation in one workflow – from production data to finished report.

The workflow

From barn data to finished documentation

1 · Describe production and building

Choose species, numbers, weights and production form – the program calculates heat, moisture and CO2 production using the CIGR models. Add building geometry and U-values so heat loss is included from the start.

2 · Select components

Assemble the system from inlets, exhaust units and heating/cooling components with documented performance data – use the standard library or your own company file with up to 10,000 components.

3 · Simulate the whole year

Run hour-by-hour simulation with local weather data: barn temperature, humidity, CO2, electricity and heat consumption – and emissions with the emission module. Compare scenarios with duration curves.

4 · Print the documentation

Compose the report for the permit file, the client or the quotation – with your logo, parts lists and CSV export for further analysis.

Capability areas

What StaldVent calculates

  • Ventilation

    Mechanical, natural, tunnel and combi-tunnel ventilation plus diffuse air intake – in insulated and open buildings. Ventilation diagrams show the operating point, emergency ventilation can be verified for power failure, and a dedicated module calculates the impact of wind.

  • Heating & cooling

    Building heat loss from geometry and U-values; design of smooth, spiral-ribbed and finned pipe systems; spray, PAD and mechanical cooling; geothermal heat exchangers and heat recovery.

  • Energy

    Annual simulation of electricity and heat consumption with set-points for temperature, humidity and CO2 and your choice of control strategy – including outdoor-temperature compensation and custom control characteristics.

  • Emissions

    Ammonia production, concentration and emission hour by hour; odour emission; cleaning efficiency at full or partial air cleaning; a working-environment index based on CO2 and NH3.

  • Specialist modules

    Central and semi-central exhaust · CHP · tube ventilation  · SI/Imperial units · additional languages · quotation module · database module with links to ERP systems such as Navision and SAP.

Frequently asked questions

An ordinary Windows PC. The program is lightweight, runs fine on laptops – and installs in minutes.

Yes. Companies maintain their own component files with tested performance data, so calculations match your product range exactly.

Yes. Simulations run on hourly weather data for the specific location – in any climate zone, heating- or cooling-dominated.

From published research: CIGR heat production models and component test data from the Danish research centre at Bygholm. See more under About StaldVent.
