# Comfort score

A comfort score is calculated for each home for the current situation and potential situation based on the home characteristics. To each of the characteristics is awarded a number of points with a maximum total of 61 points for a home.

#### **Comfort score output**

```
"comfortscore": {
    "current": 1,
    "potential": 4

The presence of a WTW shower or solarpanels has no influence on comfort and therefore does not count. The total number of points is the sum of the points per characteristic, which for glass insulation the value for the glass type of the living space is used.&#x20;

Based on the total achieved number of points, the number of comfort stars is then determined for the house according to the table below.

| Points | Score |
| ------ | ----- |
| 2-20   | 1     |
| 21-30  | 2     |
| 31-40  | 3     |
| 41-50  | 4     |
| 51-61  | 5     |
