Domes and Solar Radiation

Domed roofs have great structural advantages, but also some significant thermal advantages due to their response to incident solar radiation. This article presents a quick outline of this response when compared to flat or inclined roofs.

Making a Thermal Comparison

One of the first things many people say when introduced to analytical software is -- "OK, but just how accurate is it?". The accuracy of analysis software is important, but in the case of a thermal analysis tool this is not a simple question to answer. This article discusses the many issues you must first consider before comparing measured thermal values against simulation results, not just in ECOTECT but in any thermal analysis tool. It also makes a case for concentrating on relative accuracy in simulation rather than absolute accuracy.

Thermal Modelling: The ECOTECT Way

For ECOTECT to properly understand a thermal analysis model, it requires that you adhere to some specific conventions when constructing it. A lot of work has been done to ensure that you can effectively model most building situations and that the same model can be both analysed in ECOTECT and properly exported to other tools such as EnergyPlus and ESP-r. This article outlines the important elements you must remember when creating thermal models and explains a few shortcuts you can take when modelling multi-storey, multi-zone and earth-bermed buildings.
