“Energy efficiency in a building is achieved by addressing small improvements at every possible opportunity. The ability of IES’ VE software to construct a detailed model and perform simulation within a short time has been crucial to achieve high efficiency at a low capital cost for our clients. I have looked into various building simulation software tools in the past and, in my opinion, IES has the best overall balance in terms of modelling details, ease of use and stability. In short, it allowed complicated issues to be studied quickly to give the best solution for our clients.”
