N2 - Future tightening of the energy requirements increases focus on design of new and better performing buildings with good<br/>indoor environment and only limited extra cost compared to new buildings today. This paper presents a method for economic<br/>optimization of the design of new low energy dwellings that takes into account the indoor thermal environment. By use of the<br/>criterion of cost of conserved energy implemented in a Microsoft Excel sheet, a cost optimal design according to a targeted<br/>energy frame can be found. The resulting indoor thermal environment is then evaluated based on parametric analysis in the<br/>dynamic simulation tool WinDesign. If any changes have to be made to ensure a good indoor thermal environment, iteration<br/>between the two programs must be performed. An example is used to illustrate this process. It indicates that the method can be<br/>used from the early design phases to ensure that an economic design solution with good indoor environment can be identified.<br/>The example also shows that in order to ensure that buildings have low energy consumption, at minimum extra cost, more<br/>appropriate products and solutions will have to become available on the market at a competitive price.
