The design methodologies require applying techniques in the phase of generating options, selecting methods to achieve the best of them, and thereby meeting the needs of the various requirements of the project. In the forest industry, the case of engineering glued laminated timber is not immune to these demands. Using the methodology of Integrated Environmental Design (IED) and the Muticriteria Technical Decision (MCTD) method, referred to the stage, it was possible to achieve the successful consolidation of design and conceptual development of a new constructive component of structural quality with technical innovation criteria based on the use of optional materials and new manufacturing processes. First, a total of 53 alternatives to the structural elements were generated with the creative brainstorming technique. Secondly, a selection technique was carried out according to the environmental, socio-economic and technological change, which came to define alternative 7. Using the Expert Choice 2000, it was chosen among the last 7, option number 39. This one met the requirements of the above factors in terms of cost, quality, resistance and Ecodesign principles, such as reduced energy consumption, use of alternative raw materials such as grass, recycling and reuse of raw materials, among others.
