KS ENERGY AND SUSTAINABLE DEVELOPMENT GROUP 2.3: LARISSA HAMILTON MANUEL PÖLLINGER CHRISTIAN UNTERBERGER Re-inventing buildings Visions for future building design
Introduction Buildings play an important role in our society Austria: nearly 40% of final energy used in buildings Around 80% for providing thermal energy services Changing buildings – key element for improving our energy system
Passive Houses What makes it different to “normal” buildings: 1. Special insulation 2. Specific Heating System 3. Particular Ventilation System
Passive Houses- Insulation Passive house insulation vs. normal house insulation
Passive Houses- Insulation Consists of very thick walls Stuffed with mineral fibrous insulating material Conventional walls consist of bricks Insulating double or triple glazed windows Single glazed windows energy wasting installation
Passive House -Heating Heat pumping systems Solar heating system for heating water Heating by electricity which is generated by photovoltaics
Passive House-Ventilation Systems Nearly airproof covering due to insulation Air renewal rate between 0,3 and 0,5 ( measures how much air renewed within one hour)
Plus Energy Houses Low need of energy Energy not supplied by electricity providers Higher self-production of energy than use 100-percent regenerative energy supply and emission-free process Excess of self-produced energy fed into public network
Plus Energy Houses - Functionality “Save energy and produce a surplus of electricity, rely on solar power and only use regenerative energy!”
