Development ofPassive Houses
![Page 8: A STEP TOWARDS A CARBON-NEUTRAL FUTURE Passive Houses](https://reader036.vdocuments.mx/reader036/viewer/2022081513/5697bfd41a28abf838cac872/html5/thumbnails/8.jpg)
Idea and Implementation
• emerged from a conversation between Professors Bo Adamson and Wolfgang Feist in 1988
![Page 9: A STEP TOWARDS A CARBON-NEUTRAL FUTURE Passive Houses](https://reader036.vdocuments.mx/reader036/viewer/2022081513/5697bfd41a28abf838cac872/html5/thumbnails/9.jpg)
Prof. Bo Adamson, co-originator of the
concept
Dr Feist, founder of the Passivhaus
Institut and co-originator of the concept
The inventors

Evolution
• first Passive Houses:Darmstadt (Germany) in 1990
• foundation of Passivhaus-Institution (1996)
• creation of the Economical Passive Houses Working Group (1996)
• further constructions in Stuttgart, Wiesbaden, Naumburg and Cologne
![Page 11: A STEP TOWARDS A CARBON-NEUTRAL FUTURE Passive Houses](https://reader036.vdocuments.mx/reader036/viewer/2022081513/5697bfd41a28abf838cac872/html5/thumbnails/11.jpg)
Expansion
•further commercializing due to CEPHEUS
=>proves the concept in 5 European countries (2000-2001)
• first passive house in North Amerika, (Urbana, Illinois in 2003)
• first Passive House to certified: near Bemidji, Minnesota in Waldsee(2006)

Today
•about 15.000 Passive Houses in Europe
•including : single and multifamily residences, schools, factories , office buildings and even governmental agencies

Advantages and Disadvantages
![Page 14: A STEP TOWARDS A CARBON-NEUTRAL FUTURE Passive Houses](https://reader036.vdocuments.mx/reader036/viewer/2022081513/5697bfd41a28abf838cac872/html5/thumbnails/14.jpg)
Living Comfort

due to the air condition system...
•very good air quality
•same temperature in all rooms
•opening of windows and doors does not have a great impact on temperature
![Page 16: A STEP TOWARDS A CARBON-NEUTRAL FUTURE Passive Houses](https://reader036.vdocuments.mx/reader036/viewer/2022081513/5697bfd41a28abf838cac872/html5/thumbnails/16.jpg)
Costs
![Page 17: A STEP TOWARDS A CARBON-NEUTRAL FUTURE Passive Houses](https://reader036.vdocuments.mx/reader036/viewer/2022081513/5697bfd41a28abf838cac872/html5/thumbnails/17.jpg)
•initial building costs up to 17% higher
![Page 18: A STEP TOWARDS A CARBON-NEUTRAL FUTURE Passive Houses](https://reader036.vdocuments.mx/reader036/viewer/2022081513/5697bfd41a28abf838cac872/html5/thumbnails/18.jpg)
•equalled out by saved costs for heating
![Page 19: A STEP TOWARDS A CARBON-NEUTRAL FUTURE Passive Houses](https://reader036.vdocuments.mx/reader036/viewer/2022081513/5697bfd41a28abf838cac872/html5/thumbnails/19.jpg)
Comparison of energy consumption of different types of houses

➡on average: equalled out after 21 years

Can you upgrade a house into a Passive
House?
![Page 30: A STEP TOWARDS A CARBON-NEUTRAL FUTURE Passive Houses](https://reader036.vdocuments.mx/reader036/viewer/2022081513/5697bfd41a28abf838cac872/html5/thumbnails/30.jpg)
•construction is not constricted to specific types of buildings
• every building can be upgraded into a passive house
![Page 31: A STEP TOWARDS A CARBON-NEUTRAL FUTURE Passive Houses](https://reader036.vdocuments.mx/reader036/viewer/2022081513/5697bfd41a28abf838cac872/html5/thumbnails/31.jpg)
Passive Houses
•very good heat insulation
•air conditioning to gain heat
•windows with good heat insulation (heat protection glazing)
•walls of a passive house are not permeable to air
![Page 32: A STEP TOWARDS A CARBON-NEUTRAL FUTURE Passive Houses](https://reader036.vdocuments.mx/reader036/viewer/2022081513/5697bfd41a28abf838cac872/html5/thumbnails/32.jpg)
• You can upgrade every house into a Passive House but the costs and investments are very high.

Where are Passive Houses bulilt?
•in German-speaking countries
•in Scandinavia
buildings increase mostly Europe,
