About StaldVent

StaldVent is a decision support PC-program for designing ventilation and heating (or cooling) systems for livestock buildings, and for analyzing the indoor thermal climate and energy consumption. Using StaldVent simplifies the design optimization process for ventilation and indoor climate management, which can lead to an improved working environment, better animal welfare, and reduced energy consumption. StaldVent allows environmental footprint prediction using annual-basis simulation of gas emissions, air cleaner efficiency, and energy use.

StaldVent can be used as a neutral standard for comparing different ventilations systems – including mechanical, natural, tunnel, and combi-tunnel – on the basis of selected criteria. It can be used for design in any global climate, whether heating or cooling dominant, and for many livestock species.

StaldVent allows the input of market-available ventilation components as a reference file to produce a parts list, which makes it useful for both consulting professionals and ventilation equipment supply companies when designing and quoting jobs. The simulation module makes it an effective tool for troubleshooting ventilation problems with installed equipment, which can improve time efficiency when on site for technical follow up.

The software is mainly based on research made at the Danish Agriculture Research Center, Bygholm, and other internationally published research. Different heat models including model by Strøm/Feenstra and GIGR 2002 is implemented a long with different models for heat stress /climate index and chill effect. The software can handle several different ventilation systems including mechanical, natural, tunnel and combi-tunnel systems.

The integrated climate module help identifying the most suitable (favorable) ventilation/cooling/heating/ heat recovering system for different climate zones, hereby saving energy and minimize environmental footprint.

Evaporative and mechanical cooling/humidifying systems can be modelled, and annual water consumption determined.

The user interface is built with graphics presentation using time curves and duration curves that gives a good overview of the simulation results. Up to 10 individual simulations can be performed on annual basis. This makes it very easy to demonstrate advantages and drawbacks for different ventilation system setups. The simulation capacity also makes it a good tool for trouble shooting as consequences of malfunctioning equipment can be analyzed.

A close integration of data for the customers own components help to secure that a well-functioning system is offered.

In the real world, StaldVent fills out the gap between scientists and engineers by combining multi-disciplinary research from bio science and mechanical engineering into an operational simulation tool.

Staldvent is used as an education/teaching tool giving the students a quick overview of the interconnection   between different ventilation and heating parameters.

StaldVent is also being used as a test platform where a consequence analysis of new environmental models and inventions can be predicted. The user can to some extend implement his own equations for ammonia and odour generation, chill effect and climate index etc.

StaldVent can be used as an objective (neutral) standard for comparing different ventilation systems.

StaldVent can be used as a neutral standard for comparing different ventilations systems – including mechanical, natural, tunnel, and combi-tunnel – on the basis of selected criteria. It can be used for design in any global climate, whether heating or cooling dominant, and for many livestock species.

In Denmark it also has been used for approval of ammonia emission with air cleaning systems.
