JVVA is leader when it comes to Advanced Modelling. This is one of our key expertise areas as it normally forms an important part of performance based design. Our technical expertise in this area cannot be overemphasized; we uses advanced modelling as an advantageous tool to meet the required design objectives. It is not only the technical modelling in itself that we do, especially the identification of when this type of analysis is appropriate and necessary is something which is of great value to our clients.
One of our main areas is the use of CFD to evaluate smoke movement. Computer simulations of smoke movement in large and/or complex spaces such as atria, airport terminals, and malls has the potential to enhance system design, to reduce cost and complexity. Smoke Control can have a major impact on the overall design of the building it needs to be considered at the earliest possible stage of the design process.
We also use advanced modelling for pedestrian planning/design analysis and evaluation of emergency movement. For these types of analysisit is necessary to have a deep understanding of crowd behavior and crowd management. The specific objectives could be several; for large transportation system it is necessary to optimize people flows and identify shortcomings in the design, for stadia a typical analysis is to evaluate the exit capacity in an emergency situation, and for a commercial premises it could be to design pedestrian routes in such a way that they maximize the exposure of services to the occupants.
Another area where we perform advanced analysis is structural fire safety. This type of analysis evaluates the thermal effects of fires on structural members. By the use of heat transfer and finite element analysis the structural response to design fires can be determined, and in this way it is possible to assess the structures strength in fire conditions. Analysis of this type is often used as a performance based design alternative to the traditional prescriptive approach which could be costly, non-aesthetic and difficult to maintain.
