Nice to have is to fix the units here and add a total residence value?

Perhaps this chart is not very clear in its explanation. Is it useful heat demand? Does it include space heating and hot water? The description is not much clearer "This bar chart shows the residential heating demand per residence type and building period."

Had to check the queries to see what it actually does. It is only the useful demand for space heating. Changed the descriptions to include this.

Insulation sliders still to be done
Created the front end for the new sliders, including a new figure for the number of buildings (combined with number of houses).
In some descriptions a link wasn't working. The one below is an example of one that didn't work. It didn't work because there was no "/" before scenario. This was actually a recurring bug in more descriptions. I fixed it for other descriptions not related to this project as well.

<a href="scenario/flexibility/flexibility_weather/weather_years">Weerjaren</a>
- Removed old housing stock figure
- Changed title of building stock figure
- Added subheaders between construction & demolition
- Moved behaviour slider to "demand growth" instead of insulation
- Updated description of insulation slider to refer to moved behaviour slider

- Changed the descriptions on the behaviour slider to include examples
- Changed the slide name Heat demand and insulation to Insulation
- Changed the description for insulation to be more clear
- All changes for both Dutch and English
Implemented changes to align wording for new building and households sliders. Including the descrioption of insulation sliders, subheader for insulation sliders, descriptions for demolished households.

Also changed the slide name 'Development of demand" to "Behaviour" for both buildings and households. Changed the description a bit as well.

Finally, changed the title and description of the "Residential heating demand" figure.
