Triple Zero® is a standard developed by Werner Sobek to define the demands a building must fulfil to satisfy aspirations regarding environmental sustainability. The name Triple Zero® is protected by trademark law. R128 is a good example of a building fulfilling Triple Zero® standards.
Zero Energy Building
The building requires no (ZERO) energy. The energy generated from regenerative sources on and in the building or the immediate piece of property upon which the building stands is at least equal to the entire primary energy requirements of the building for heating, cooling, hot water, auxiliary power and power for all typical domestic applications.
Zero Emission Building
The building produces no (ZERO) CO2 emissions. The reference value is the total primary energy demand, which is then converted to CO2 emissions. No burning processes are permitted in the building or on the property.
Zero Waste Building
No waste (ZERO) is produced when the building is being converted or deconstructed. At the end of their life cycle all building elements can be fully recycled without any components needing to be burnt or sent to a disposal site. The plot of land can be returned to nature without any fear of contamination or residual waste.
