When you perform solar and thermal calculations in Ecotect, it does not do these for any specific year, but rather a standard 'average' energy year. This is true of nearly all thermal and energy analysis tools. Even the weather files used for solar and energy analysis are usually averaged to better represent long-term conditions. This article explains the basic assumptions behind the 'average' energy year and why this approach is more appropriate than using any particular year.
Scripts have been available in ECOTECT from very early on in its development and are probably one of its most under-utilised features. Anyone can write and run a script in ECOTECT and they can be used to add new functionality, automate complex tasks, initialise or standardise a model to your firm's requirements, generate summary data, export to another application, etc. Pretty well anything you can imagine. This article is a brief description of what a script is and what it contains.
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.
