Will equation-based building simulation make it? experiences from the introduction of ida indoor climate and energy | 2003 | English
In building simulation, as in several other domains, traditional monolithic simulation codes are still in dominance over simulators based on symbolic equations in a general modeling language.
Useful waste heat of ventilated pv-modules: physical modelling and validation results | 2003 | English
The "PV/T-Slate" is a recently developed ventilated photovoltaic slate for integration into roofs or facades. As side effect of the cell cooling the heated air can be used. Therefore it is useful to simulate air volume rate and temperature.
The use of computer simulation to establish energy efficiency parameters for a building code of a city in Brazil | 2003 | English
The first energy efficiency law for Brazil was presented in 2001, which required that buildings should have some energy efficiency regulation. Salvador city building code was then submitted to a study to include energy efficiency par
In an existing integrated building design tool, BSim2002, a 3D building model can be created. The model can be used for thermal simulation, but also for other purposes, e.g.
