123 56 IronCare - Student and commercial ironing service I. Cordius1, M.B. Eriksen1 1DTU Mechanical Engineering, Technical University of Denmark This solution has two parts; we will be describing each separately. At some point in time, most people will have to face the challenge to iron their clothes for a fancy event. People often encounter this challenge for the first time while being a student. Students (and other unexperienced ironers) rarely spend the money required to get durable ironing equipment, while achieving inferior ironing results. Materials and energy are being wasted on cheap ironing equipment lasting just a few uses. We have designed an environmental-friendly solution to this wasteful problem: a product-service-system, which deliver premium quality ironing at student dormitories. Using the functional unit of “ironing of 1 piece of clothing six times a year” this solution for dormitories will result in a factor 4,9 improvement in energy use. In Denmark, employees of big companies require ironed clothes for their daily routine. This creates issues for employees that bike to their workplace: they need to change clothes at the workplace, clothes is difficult to carry on a bike without creating wrinkles. This keeps employees from taking the bike, and leads to more using the convenient, but environmentally undesired transportation option: driving to work by car. We have designed an environmentally friendly solution to this problem: a productservice system, which deliver ironing of clothes at the workplace. We expect to alter the transportation behaviour of employees to using the bike for transportation more often. This solution will result in a factor 2,4 improvement the energy usage. The two described service systems are integrated into one service-system, which provide the optimal use of the equipment involved, as the same irons will be used both in the companies and at the student dormitories. On the long term, we hope to decrease the number of irons, by eliminating the need to own an iron.
