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