First hand experiences

Design

Performing the building refurbishment there are many alternatives possible, that should be evaluated according to the system of qualitative and quantitative criteria. This problem could be solved applying web-based intelligent technologies.

Application

It is difficult to forecast the prices of refurbishment works as economic situation in transitional economies is hardlier predictable comparing to the developtive countries.

Further experiences

During the VGTU renovation aiming at energy savings measures, modifications occurred. Because of financial shortages the third renovation component, i.e. ventilation and in consequence the ventilation system, was not foreseen to be refurbished. However, in the process of renovation the three main components – building envelope, heating and ventilation - must be kept in balance. As € 42,605.61 was saved by replacement of the windows, it was therefore decided to use that money for the renovation of the ventilation system.
