Thema: Factor X Settlement

6 posts

"Factor X" is a method for Measuring resource efficiencywhich was developed by the Federal Environment Agency and adapted by the Factor X agency in Inden (between Aachen and Cologne) for buildings and new housing developments. The Factor X records the construction, the use of the houses and the infrastructure (roads, paths, lighting) of the new/construction areas. Standard building designs provide reference values against which the Factor X target value is calculated. A manual helps to find solutions to achieve the target values. Which concepts are ultimately favoured is left to the planners and those responsible. The resource consumption of the buildings is given per square metre of living space.

A Factor 2 residential area consumes half of the resources usually used over its life cycle. The Factor X Agency is housed in a new building with Factor 3.5, which was realised as a Factor X model house. At around 2000 euros/m², the construction costs are within the usual local range for a building of this standard.

The online tool KuRT (Climate and Resource Protection Tool; link: https://kurt.faktor-x.info/) calculates the resource consumption of buildings, taking into account the building materials used and the energy consumption during building use over 50 years. KuRT makes it very easy for users to calculate the factor X of a building.

To this end, four categories of resources are considered:
- Abiotic Resources (RI abiotic),
- Greenhouse gas potential (GWP = Global Warming Potential)
and
- the cumulative energy expenditure (PENRT = Primary Energy Non Renewable Total) .

To date, there are five Factor X development sites (three of which are under development).
