Optimal window structure option on the initial project stage

Prognostication of building energy consumption lets define its lowering ways possibility on the initial project stage by for example envelope isolation. Energy consumption prognostication of the one-floor office building located in St-Petersburg, Russia with IDA ICE programme and optimal window structure option with minimum energy consumption are considered in this study. Modeling concept allow to get heat loss and heat gain information and also define optimal window structurewas introduced.
