First hand experiences

Design

The finding of the architect that the minimal construction of the roof was already strengthened because of the crane, so it could actually carry the weight of the additional insulation

The competition between the window manufactures made it possible to come up with quite low U-values for the whole window even considering the rather small individual glazing areas.

Monitoring

As always the first reaction from the contractors is that “this is too expensive”. In the actual situation it was the BEMS system. But by negotiations it finally got through the process.

Further experiences

The main impression is that by pushing and trying hard enough you can move “what is possible” quite a bit further than what is first indicated by building designers and contractors. The examples of this experience are:

• The finding of the architect that the minimal construction of the roof was already strengthened because of the crane, so it could actually carry the weight of the additional insulation.

• The competition between the window manufactures made it possible to come up with quite low U-values for the whole window even considering the rather small individual glazing areas.
