In the summer semester of 2011, Harald Gruendl co-supervised the module “Sudeco… for sustainable design and communication strategies” for the Department for Spatial and Sustainable Design (Prof. Françoise-Hélène Jourda) at the Technical University of Vienna. The students’ task was to design hanging lamps made of a material with sustainability in mind (paper!) and get them ready for the market.The varied results will be presented in the “ecoLUCY” exhibition at the Zumtobel Light Forum during ViennaDesignWeek 2011!
Opening event (within the framework of ViennaDesignWeek 2011): Monday,October 3rd, 08 pm
Exhibition open till October 21st
Opening hours: Mo - Thu 08.00 am - 05 pm, Fr 08 am - 1 pm
Location: Zumtobel Lichtforum Wien, Jasomirgottstraße 3-5, 1010 Vienna
Harald Gruendl (EOOS/IDRV) on the project – A World Made of Paper
A plate and a cup made of paper. A chair and a table made of paper. A computer housing made of paper in a house made of paper. We clothe our nakedness with paper. We design a sustainable new world; we have realized that we cannot continue in this way. Through the exploitative use of resources and the emission of pollutants, western consumer culture has brought the world out of kilter, socially and ecologically. We need a new design of our living environments. All things must be rethought. Design must reinvent itself, and we find ourselves at the beginning of this transitory phase. But the right things need to be thought and done. Carbon dioxide is the most well-known environmental factor, because the emission of CO2 causes the greenhouse effect and with it, dangerous global warming.
By making the reflector of a lamp out of paper, the production of the individual lamp creates less CO2 compared to an aluminum reflector; under realistic assumptions, instead of 17 kg, only 9 kg of CO2 pollutant are emitted. But in order to light a room of about 60 m2 according to office standards, for example, more paper lamps (16 instead of 12 at a height of 3 meters) are needed, since the reflector reflects less light. Thus, the 16 paper lamps save only 13kg of CO2. After about 650 operating hours (0.18 kg CO2/kWh), the advantage of the paper lamp is eaten up. From then on, the paper world is not more environmentally friendly. We must build a new world with new consciousness and poetry – not from paper.
 I wish to thank the Zumtobel company for supporting my course, especially Mr. Christoph Mathis for his quick approval, and Mr. Sebastian Gann for his ardent scientific supervision of the Life Cycle Assessments.
