“…The design phase provides the greatest possibility for affecting the energy efficiency of the product and its production, and lays the foundation for subsequent work with energy efficiency. The product design has also been raised in previous research as important factors for reduced use of energy and other resources as well as reduced environmental impact; see for example Reference [6][7][8][9][10]12,14,[17][18][19][24][25][26]31,[44][45][46][47][48][49][50]. In the design phase, a life cycle perspective, including the manufacturing phase (e.g., production processes, packaging, transportation, and storage), the use phase and end-of-life handling is important [14,18,24,26,44,49].…”
