CoDyBa (CDB_dDDN_V2) is a software system designed to determine the energetic fluxes of a building zone, i.e. how quickly and effectively it is processing or indeed wasting its heat. It assesses the climatic conditions, the internal loads, the heating and air-conditioning systems and their regulation, then calculates the thermal behaviour of a building. From here it can predict how great the building’s need for DuPont™ Energain® is – and in what quantity.

Assessing the thermal behaviour of a building has been the object of numerous software developments over the last thirty years, yet CoDyBa is probably one of the most precise and effective. In development since 1981, the standard programme was originally the result of a thesis, and has been available as a commercial version since 1985. It is the recent developments in the software that have been the most significant though – the actual design of the product has been reversed, reinventing the way that such calculations were traditionally made.

Thus, the standard version of CoDyBa is able to offer heat engineers and technicians a method of accurately establishing the energy balance of a building and of analysing parameters such as windows, solar protections, building inertia and orientations. Reliable, simple to use and undeniably revolutionary, CoDyBa represents a huge breakthrough in its field.

For the purposes of calculating for DuPont™ Energain® a special version of the software has been developed and proprietary of DuPont. A ‘ lighter ‘ version of the software is under development and will be available around mid 2007 on the DuPont™ Energain® web site.
