The Dynamic Simulation Program

A completely new interface for our dynamic simulation program has been developed. The new generation simulator, currently called TBD, has retained the robust and well validated calculation code from our original software. But, this has been augmented to use Fortran95 compiler optimisations, giving even faster simulation times for your models. The calculations are now underpinned by completely new and very flexible database technology, which will enable more rapid and easier application development in the future.

The redesign of the interface and data structures has meant that the interface can mimic the natural hierarchical nature of the building data. Add to this the use of familiar Windows^TM common controls and the software is immediately more intuitive and easy to us. Data is more readily accessible and easier to manipulate, helping speed up the simulation design cycle. Any size of building may be simulated with the limit on the number of zones, apertures, surfaces etc. determined only by the resources of the PC running the software.

In this demo the building already input from the modelling demo is dynamically simulated for a complete year. The new generation software has separated out database functionality for weather, constructions, calendars and internal conditions, into independent applications. This demo introduces the weather and construction databases and then performs a simple freewheeling simulation of the building for a whole year. At this point, the new result viewing software (currently called TSD) is automatically started to allow the interrogation of the simulated results.

Using predefined and user specific output filters any combination of output parameters can be viewed together, over any period of time. For example external global radiation, room solar gain and room cooling load may be viewed together to show the effectiveness of solar shading and thermal mass.
