KS ENERGY AND SUSTAINABLE DEVELOPMENT
GROUP 2.3: LARISSA HAMILTON MANUEL PÖLLINGER CHRISTIAN UNTERBERGER
Re-inventing buildingsVisions 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
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!”
