Challenge

Energy certificates slow down listings

An energy performance certificate is mandatory for every sale and rental, and it is often exactly the bottleneck that holds up a listing that is otherwise ready.

The certificate inside the listing process

Sellers and landlords should get an energy certificate quickly, right where they prepare their listing: with the product Energieausweis 48.

What changed

Before

Listing prepared
Energy certificate missing
Delay
Listing live

The energy certificate requirement holds up the finished listing.

After

Listing prepared
Energieausweis 48
Listing live

The certificate is ordered directly within the listing process.

Solution

Energieausweis 48

Integrated tool

Energieausweis 48 as part of the IS24 listing process, with responsibility for frontend and product development.

React codebase

Laravel routing integration

Dedicated Webpack configurations keep the transition between the PHP/Laravel backend and the React frontend clean.

Typing with TypeScript

Structural improvements to a platform that has grown over many years: clearer component boundaries, fewer legacy patterns.

Building on a live marketplace

No greenfield: every change is weighed against its effect on existing features.

Result

Live and still evolving.

Energieausweis 48 is in the market and under continuous development. Since 2022, alm has contributed to ImmobilienScout24's frontend development as embedded senior capacity, as part of the team and not as an external supplier.
