It is widely acknowledged that the use of experimental works have been applied in various research fields, engineering design, and technology in order to increase product performance and quality. For decades, many researches, scientists, and engineers, have used experimental design (e.g. modelling and simulation) to explain some kind of causation, to provide answers to research questions, to control variance (differences), and to reduce design costs. Speeding up the design process, reducing design changes, product material and labor complexity, and achieving manufacturing cost savings are argued as the result of the experimental design. In sum, experimental can be used as a vehicle for knowledge production in research through design, and it helps us to improve our everyday lives. This season, we are delighted to present the special edition of International Journal of Technology (IJTech) dedicated to improve research outcomes in engineering design and technology particularly through experimental research. This special edition presents twelve selected papers from the 13th International Conference on Quality in Research (QiR 2013) in Yogyakarta, Indonesia. This special issue discusses on the experimental works and simulation of integrated design in urban eco-technology that providing information, evaluation, and empirical solution as well as the contributions to the existing and future development of humanity.
