Advantages of simulations
Simulations are a tool for the overall optimisation of buildings, sites or infrastructure structures. The building is considered holistically across all trades. All system components interact with each other and the entire life cycle is taken into account. This allows questions to be answered early on in the planning phase and uncertainties to be eliminated. This creates a wide range of added value for the environment, the client, the construction project, the investor and the user of the building.
Our success stories
Overall, simulation success stories provide concrete examples of how these technologies can help to plan and design better and more efficient buildings and sites, and motivate decision-makers to use these tools in their own projects.

Optimal indoor climate for gymnasts at the Magglingen National Sports Centre
The National Sports Centre Magglingen (NSM) is an important training, sports and congress centre for Swiss sport. Gruner Gebäudetechnik Bern has been carrying out various renovation works on the NSM's building services systems since 2020. One of these measures concerns the Jubilee Hall, the training hall for artistic gymnasts. The hall of the existing building from the 1990s was originally heated exclusively by supply air...

Natural ventilation and adaptive strategies: efficiency and comfort at the centre of the STEP2 research unit at NEST
Aktuell gibt es keine konkreten Normen für natürliche oder hybride Lüftungskonzepte. Oft werden absolute Ziele verlangt, die mit dem variablen Aussenklima als Energie- und Frischluftquelle nicht vollständig erreichbar sind. Durch den Verzicht auf behagliche Perfektion können Mechanisierung und Installationen reduziert werden, was die Kosten und Emissionen senkt. Passive Konzepte benötigen meist weniger Gebäudetechnik und reduzieren… Continue reading Natürliche Lüftung und adaptive Strategien: Effizienz und Komfort im Fokus der STEP2-Forschungsunit auf dem NEST
Innovative planning in the Sky high-rise: Successful ventilation optimisation through flow simulations
In the Sky high-rise building in Stettbach (client: Publica), CFD simulations were used to test the feasibility of the following two ventilation optimisations. On the one hand, it was investigated whether the ventilation ducts in the ceiling of the flats could be dispensed with. On the other hand, the simplification of the ventilation duct network in the underground car park was analysed.
Development of landside passenger space (ELP) at Zurich Airport: focus on sustainability and efficiency
In order to cope with the growing flow of passengers and commuters at Zurich Airport, the northern part of the airport shopping centre is being completely renovated with the ELP project. The central element of the project is a new twelve-metre-high food hall between car parks 1 and 2 with fixed stands, food trucks and a bar.
Innovative ventilation strategies for car parks: cost savings through CFD simulations
Medium-sized and large car parks need a sufficient exchange of fresh air so that the concentrations of carbon monoxide and nitrogen oxides do not become dangerously high. With the help of a flow simulation (CFD), the distribution of these particles can be tracked, analysed and optimised.
Simulation study to optimise summer heat insulation and energy requirements in SBB buildings
The SPF Institute for Solar Technology was commissioned by the HVAC engineering firm Tri Air AG on behalf of SBB AG Immobilien Bewirtschaftung to carry out a simulation study to examine the need for active cooling and the total energy requirement with different variants.
Innovative technology for Olma Hall 1: Efficient air conditioning and fire protection concept for St. Gallen's leading exhibition and event hall
With the new Olma Hall 1, the largest column-free hall in Eastern Switzerland, St. Gallen and the entire region will become the number one exhibition, event and congress centre. AFC AG supported the development of the integral overall building climate concept and the property-related fire protection and smoke extraction concept by means of simulations and conceptual expertise.
Sustainable education centre: Innovative technologies and planning strategies for energy-efficient school buildings in Luxembourg
The ambitious goal for the new technical high school for health professions in Luxembourg was for the building to pay back the energy used for its construction and demolition during its lifetime. Therefore, not only an energy-efficient building envelope was required, but also an energy-optimised system for ventilating and heating the administration and training rooms.
Efficient use of process waste heat: optimisation of the new lake water plant in Ipsach for a sustainable drinking water supply
The new lake water plant in Ipsach will produce drinking water for 70,000 people in the Biel/Nidau region in the canton of Bern. EPRO ENGINEERING carried out a comprehensive simulation study in IDA ICE (useful energy) from EQUA and Polysun (system simulation) from Velasolaris to ensure that the waste heat from the process can be utilised optimally.
