```

## 2. Input Changes

### a. Basic Features

#### New Inputs

* `roof_type`
* `electric_cooking`
* `cooling`

#### Renamed Inputs

* `roof_insulation` → `sloped_roof_insulation`
* `roof_insulation` → `flat_roof_insulation`

#### Solar Panel Input Changes

The `solar_panels` structure has changed from a **single integer value** to a **list describing individual solar panel installations**.

New solar panel related fields include:

* `solar_panels` (per solar panel)
  * `pv_total_watt_peak`
  * `pv_area` 
  * `specific_watt_peak`
  * `angle`
  * `orientation`
  * `roof_type`

## 3. Output Changes

The response structure now includes additional fields and updated naming.

#### Renamed Outputs

* `roof_insulation` → `sloped_roof_insulation`
* `roof_insulation` → `flat_roof_insulation`

#### New Outputs

* `cooling`
* `electric_cooking`
* `solar_panels` (per solar panel)
  * `roof_surface`
  * `roof_type`
  * `original_watt_peak_capacity`
  * `total_watt_peak_capacity`
  * `inclination_angle`
  * `orientation`

## 4. Feature Value Changes

The value range for several features has changed.

Previously these values ranged from **0–3**, but they now range from **1–4**.

Affected features include:

* `wall_insulation`
* `floor_insulation`
* `flat_roof_insulation`
* `sloped_roof_insulation`
* `living_room_windows`
* `bedroom_windows`

#### Example

**v1**

```
1 = mediocre wall insulation
