Tips needed: how to respond to the Huurcomissie?

I filed a request to have the rent examined within the first six months some time ago. A few days ago, I received the inspection results.

The Huurcommissie determined that the allowed rent, based on the points system, is €1.12 too high to fall below the rent limit. The points were measured quite accurately, so my only real argument is that the apartment isn’t as well insulated as the A-label suggests.

I’ll attach a picture showing that you can literally see the street through the gap beneath the front door, which leads directly into the living room, to the response. I don’t expect this to have a major impact, but who knows—I only need a single point deducted.

Does anyone have tips on what to include to convince the Huurcommissie? Even better, does anyone know of individuals or organizations that can help with this? I tried looking for a specialized lawyer but couldn’t find one.
