Value Engineering applicability in design of sustainable, energy efficient buildings

Value Engineering is an analytical method used to optimize costs, consisting of negotiations, searching for substitutes and more efficient use of raw materials. It can be an effective support in defining material solutions while designing energy-efficient buildings. The research method adopted in this article is an analysis of the literature on value engineering and on the added value of the construction project and analysis of empirical data concerning an exemplary design solution for external walls in a multi-family building. It has been assumed that the reduction of the projected costs of the construction project (elimination of resources which do not create added value for the client) and at the same time increasing the energy efficiency of the facility are possible under the conditions of applying value engineering. The result of the calculations is the reduction of project costs according to the proposed model of value engineering
