  1. Energy performance of solar domestic hot water systems in a changing climate: 2050 vs2007 RaduZmeureanu, Concordia University, Montreal, Canada, zmeur@encs.concordia.ca Jan Menhert, Bochum University of Applied Sciences, Germany, jan.mehnert@hs-bochum.de Camille Julien,INSA de Lyon, France, pipaillon04@laposte.net Guillaume Renaud, Université de La Rochelle, France, yomrenaud@yahoo.fr Introduction A solar DHW system, composed of astorage tank of 300 l Viessmann and different evacuated tube collectors or flat-plate collectors, is considered to be installed in three different cities of almost the same latitude, and the energy performance, simulated with TRNSYS, is compared between the 2007 and 2050 climatic conditions: Montreal (Canada) 45º30’NLyon (France) 45º46’NMunich (Germany) 48º08’N. Text [°C] Results Reduction of annual electricity use for DHW due to global warming between 2007 and 2050: - 2% in Montreal, - 5-6% in Lyon, and - less than 0.5% in Munich.. Slightly greater electricity savings for evacuated tube collectors Viessmann, Vitosol 200T , compared with flate-plate collectors Viessmann, Vitosol 200F Conclusions One can expect that under scenarios of global warming, the contribution of solar energy for heating the domestic hot water would increase, and as a result the use of electricity as auxiliary source for heating will be reduced. However, the simulation results show that the potential reduction of electricity use for residential DHW systems, designed for today’s conditions, is about 1-2% in Montreal, 5-6% in Lyon and less than 0.5% in Munich. The information presented in this paper is useful to policy makers and investors, manufacturers of renewable energy technologies, designers of solar DHW systems, and homeowners.
