Reuleaux-Diagram
CALCULATOR
Info
The Reuleaux chart calculator calculates the sustainability and a rating, based on the Three-pillar model of sustainability , but can also be useful as a "consensus meter" for other purposes.
The Reuleaux diagram calculates the intersection of three circle entities whose center is on a respective vertex of an equilateral triangle and whose maximum radius corresponds to the equilateral triangle side.
In this case, the areas / entities of the Three-pillar model of sustainability: Socioculture (People / Society) , Ecology, economy.

Ideally, the three areas / entities (socioculture, ecology, economics) of the three-pillar model, 100%, meet the requirements of their sustainability The intersection of the three areas is called sustainability in the three-pillar model of sustainability This corresponds to the intersection of the three entities of the Reuleaux diagram, if its intersections all have the same and maximum surface content at the same time, or formulated flapsily, have 100% consensus
strong-sustainability
Example of strong sustainability:
95% shares in socioculture and
95% shares in the environment and
90% shares in economics correspond to 85.4% shares in sustainability.
average-sustainability
Example of average sustainability
85% shares in socioculture and
60% shares in the environment and
80% shares in economics correspond to 47.3% shares in sustainability.
weak-sustainability
Example of weak sustainability
100% shares in socioculture and
50% shares in the environment and
25% shares in the economy correspond to 10.2% shares in sustainability.

The three o. Examples show how intuitively it can be recognized how strong or weak the sustainability, for example, For example of a trade The raking principle is very simple and easy to understand, the surface area of ​​the cut surfaces is calculated, the calculation is however not so simple.
For this reason, there is the Reuleaux Chart Calculator.
The rating code
The rating code is a statement of the creditworthiness that is derived from the achieved sustainability value.
The rating codes of the Reuleaux chart calculator are derived from the rating codes of the international rating agencies, with the difference that not the profit but the sustainability is used as a criterion for the credit rating The percentage of sustainability determines the 22-rating rating code.

Conversion of other sustainability calculations
You can convert other sustainability calculations into a Reuleaux diagram by dividing the questionnaire and the values ​​into the areas of socioculture, ecology and economics. Important! If an area is not affected, or we can not evaluate an area for lack of information or competence, we will use 100% for this area and point out in our evaluation. If there is no area, we can not, by definition, calculate sustainability. See Fundamentals.

Consolidation of sustainability calculations
The consolidation of several sustainability calculations, Such as risk analyzes, milestones, business units, departments, etc., can be easily implemented using the Reuleaux chart calculator. Enter the sum of the maximum points to reach for each area / entity. Then enter the sum of the points reached for each area / entity.

Fundamentals
The three-pillar model of sustainability
Each area is considered equally important and equitable.
Statement: Sustainability can only be achieved with equivalent consideration for all three areas
logo
Priority model of sustainability
Individual areas are seen in their relationship and dependence on each other.
Statement: No economy without a society, no society without ecology.

In the end
The rating code is a statement about the kindness of a country, company, project etc, which is determined by international rating agencies for risk assessment. While rating ratings are determined by rating agencies, sustainability aspects are taken into account, but this is not transparent and comprehensible. The main criterion for the evaluation of the rating code is that of the international rating agencies the economic success, in the form of market domination and profit.
The percentage of sustainability and the resulting rating code are a statement of ethical responsibility, For example, a company is opposed to society and the environment. Sustainability could be the key criterion for assessing the rating without hampering the economy, since sustainability also provides for profits, but only profits that affect society or the environment in an acceptable form.
The rating code or the sustainability statement is calculated from the evaluation of the questions in a questionnaire. For the start, the questionnaire of the public welfare balance sheet can be recommended, which can be changed if necessary, as the Reuleaux diagram of sustainability No static point system is used. In principle, efforts should be made to ensure that several audits are consoli- dated to a rating code by various auditors, including various question catalogs.
Finally, it must be said that the Reuleaux diagram calculator can also be used to examine very simple projects, with a simple question catalog, for their sustainability, and the results should be used in a project documentation. The aim is to make transparent how sustainable your own project is and to prove this with your own questionnaire and the results of the key performance indicators of sustainability. If necessary, check the list of questions of the opposing party for its sustainability (or re-compile it with the Reuleaux diagram). He is actually made for it That's why there is a Docu-Clipp-Button which creates graphics for your calculations. You should add credibility and transparency to your documentation because of the professionalism.

Have fun and good luck!
