iDbuild - Consequence-conscious design decisions

Share this Post:
iDbuild is a building simulation tool ideal for design management in a goal-oriented design processes. It is developed to utilise the power of building simulation tools in the development of designs and with the intention to push performance evaluations upfront in the building design process to save time and money. iDbuild is able to illustrate how performance-decisive parameters, and combinations of parameters, affects energy performance, thermal indoor environment, air quality and daylight conditions on room level. It is thus ideal for generating a platform for consequence-conscious design decisions. Before using iDbuild, we recommend that the building design process is organised in such a way that explicit design goals regarding the quality of indoor environment and energy performance becomes decisive for all design decisions. See byg.dtu.dk for further information.

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.
