ENERGY EFFICIENCY AND SUSTAINABILITY OF BUILDINGS ART AND SCIENCE OF SUSTAINABLE BUILDINGS DESIGN - BUILDINGS INTELLIGENCE AND ETHICS OF SUSTAINABILITY Prof. dr. Marija Todorovic DERES - DIVISION FOR ENERGY EFFICIENCY AND RENEWABLE ENERGY SOURCES Faculty of Agriculture, University of Belgrade, Serbia deresmt@EUnet.yu, firstname.lastname@example.org www.rcub.bg.ac.yu/deres 2006 6th November
Presentaion to the UNESCO E-Learning audience practical experience and results obtained by the implementation of the computational modeling techniques BPS - Building Performance Simulation and CFD - Computational Fluid Dynamics with an aim to predict and optimize dynamic thermal behaviour of an integrated buildings/HVAC/other technical systems energy efficiency and indoor environment quality. AIM OF THIS LECTURE
MACHINERY, CONSTRUCTION, IMPROVEMENT AND RECONSTRUCTION BUILDING TECHNICAL ENERGY SYSTEM EXPLOATATION INPUT INCLUDING SERVICE EXPLOATATION OUTPUT OUTPUT AT THE END OF THE EXPLOATATION AND CLOSEDOWN OF THE SYSTEM Buildings consume materials, energy and produce wastes SCHEME OF THE ELEMENTARY MODEL ANALYSIS OF THE BUILDING ENERGY SYSTEM
TO TURN IRREVERSIBILITY TO SUSTAINABILITY RES-TECHNOLOGIES • The most important to delay fossil energy resources exhaustion and to reduce pollution controlling climate change are RES • Solar energy (thermal, PV and photo-thermal • conversion) • Biofuels and Biomass energy • Geothermal and Wind energy • Wave and OTEC energy • Fuel cells and Hydrogen, produced using RES • Low-carbon energy technologies combined with • improvements in end-use efficiencies
Sustainable Urban and Rural Communities employing a high percentage of renewable energy supplies shall adopt innovative and improved technical and socio-economic approaches to CHP-RES based “green electricity”, clean heating, cooling or both and integrated energy distribution networks, including combinations with conventional large scale energy distribution
