Details about iDbuild
iDbuild is developed at the Technical University of Denmark as a part of an ongoing PhD-project about the development of design methods for integrated design of new low energy building.
iDbuild is a part of a building simulation program package which also contains BuildingCalc for thermal analysis, LightCalc for daylight analysis and BuildingCalc/LightCalc for combined thermal and dayligt analysis. iDbuild is using the combined calculation engine for its purpose.
The philosophy in the development of iDbuild and the other components of the program package is to evaluate energy performance and indoor environment with an appropriate trade-off between speed and accuracy. We try to keep the input side and simulation time to a minimum without compromising the accuracy of the output significantly.
We have chosen to base the program on hourly weather data mainly because it makes little sense to evaluate the indoor environment - especially daylight - in any greater steps. However, in order to perform speedy hourly based simulations, the calculation methods are simplified. These simplification does not have significant impact on the output compared to more detailed simulation programs.
