Interactions between the performance aspects and requirements regarding Thermal and Hygric comfort, Energy, Operational and Investment Costs.: Finding the Optimum Performance for Building Envelopes

When comparing the performance of building envelopes with the demands found in building code regulations, it is quite often seen that the performance is the same as the demands - and nothing more. But these demands are not necessarily at their optimum. It might be an advantage if for example more insulation was included in the walls, the indoor climate was better, the maintenance cost was lower etc.

But how do we find the optimum of these factors?This report examine methods to find the optimal solution when examining the indoor environment and the investment, operation, and maintenance cost.
