Nearly zero energy buildings are to become a requirement as part of the European energy policy. There are many ways ofdesigning nearly zero energy buildings, but there is a lack of knowledge on how to end up with the most economical optimalsolution. Therefore this paper present a method for finding the economical optimal solutions based on the use of the cost ofconserved energy for each main building envelope part and building service system and cost of produced energy for eachenergy producing system. By use of information on construction cost and developed models of the yearly energy use for eachcomponent, a function is set up that represents the relation of the marginal cost of conserved energy and the energy use fordifferent quantities and qualities of the components.The optimal mix of solutions for the whole building is found by selecting building parts with the same cost of conserved energy.The constraint is that the total energy performance of the building is fulfilling the requirements. A case example shows how themethod with success can find the solution for a typical single family house with the energy performance requirement for 2020
