Acoustic Design and Vibration Engineering
Acoustical engineering (also known as acoustic engineering) is the branch of engineering dealing with sound and vibration. It includes the application of acoustics, the science of sound and vibration, in technology. Acoustical engineers are typically concerned with the design, analysis and control of sound by simulation tools and analytical methods.

Performance Systems Design (AVL)
The design of audio, video, and lighting (AVL) is a process that involves the creation of a comprehensive plan for the use and integration of AVL equipment within a space. This is essential for creating effective and engaging experiences in various settings such as radios, operas, theatres, concert halls, houses of worship, and many other cultural venues. The process of AVL design is complex and requires expertise in multiple areas including audio engineering, video production, lighting design, and project management. As such, it is crucial to ensure that the design is carried out by professionals with the necessary skills and experience.
Stage Engineering & Design
The design and engineering of stage mechanical systems encompasses all mechanical systems used in stage productions, such as flying bar systems, stage elevators, revolving platforms, stage wagons, trap lifts, stage tilt systems, orchestra pits, rigging systems, theatre seating systems, and any other custom solutions that a venue may require. The process of stage mechanical systems design typically consists of two stages: Conceptual Design and Detailed Design. This process plays a critical role in ensuring that stage productions are safe, effective, and engaging for audiences. It is essential to ensure that the design is carried out by professionals with the necessary skills and experience in this field.

Environmental and Construction Noise Simulation
We utilize a GIS-based environmental acoustic simulation software called MithraSIG. The Geographical Information System (GIS) provides accessibility and interoperability through its support for a wide range of formats, both for reading and writing. It also offers advanced design, editing, analysis, and rendering features. The GIS software we use is Cadcorp SIS, which was originally selected by the French National Geographic Institute (IGN) for the CSTB. This software allows us to conduct detailed and accurate acoustic simulations in a variety of environments.
The acoustic simulations of the propagation of the acoustic waves of MithraSIG are performed using powerful algorithms based on asymptotic methods.
The physical simulation engine computes noise propagation according to the requirements of current regulations, CNOSSOS-EU, NMPB2008 (octave and 1/3 octave), ISO9613, NMPB96 (XP S31-133), Harmonoise (octave and 1/3 octave) and Euro Directive 2002/49/CE, which takes into account the effect of meteorological conditions.

Daylight shapes the experience of a space like no other material and is a fundamental aspect for realising healthy and sustainable buildings. Good daylighting design can improve the health, cognitive abilities and productivity of the occupants at home, school or work while reducing the energy consumption of the building.
Daylight Simulation
- Simulate sunlight redirection with light pipes, blinds and light shelves.
- Simulate complex fenestration systems (CFS) and shading products with BSDF materials.
- Import fully detailed 3D models from Revit, Archicad, Autocad, SketchUp, Rhino and more.
- Evaluate and document compliance with the European Standard for Daylight in Buildings EN 17037.

Open BIM based MEP Simulations
The analysis of the thermal bridges is carried out using a finite element analysis based on the two-dimensional heat transfer calculation of the EN ISO 10211 code. Using this computer simulation technique, the linear thermal transmittance of each thermal bridge is obtained.
Thermal Bridges analyses the six most common thermal bridges in buildings:
- Intersection between façades
- Intersection between the façade and the floors
- Intersection between the façade and flat roof
- Intersection between the façade and the partitions
- Intersection between the façade and floor slabs between floors with balconies
- Intersection between the façade and floor slab overhang
The condensation simulation carries out the analysis based on the hygrothermal behaviour of the building materials and products, and in accordance with the analysis method of the EN ISO 13788:2012 code.
OpenBIM based CFD Simulations
Computational Fluid Dynamics (CFD) is the branch of CAE that simulates fluid motion and heat transfer using numerical approaches. CFD acts as a virtual fluid dynamics simulator. CFD software can analyze a range of problems related to laminar and turbulent flows, incompressible and compressible fluids, multiphase flows, covering various aspects of wind engineering, including pedestrian wind comfort, pollution control, thermal comfort, natural ventilation, and much more.
- Pedestrian wind comfort & compliance
- Building aerodynamics
- Wind loading & facade pressures
- Outdoor thermal comfort & heat island
- Thermal comfort
- Indoor air quality
- Ventilation
- Building envelope & thermal bridging
- Solar shading & radiation
- Data center design
OpenBIM Based FDS Fire Dynamics Simulation
Fire Dynamics Simulator (FDS) is a CFD model of fire-driven fluid flow. The computer program solves numerically a large eddy simulation form of the Navier–Stokes equations appropriate for low-speed, thermally-driven flow, with an emphasis on smoke and heat transport from fires, to describe the evolution of fire, to carry out simulations of fire evolution using the Fire Dynamics Simulator developed by the NIST (National Institute of Standards and Technology, USA).
