Interesting drawing. Takes me back a few years to a college study I did once. . . Did see some things that prodded my curiousity:

Why is there a window in the habitat? I thought this was to be covered under a couple meters of regolith?

Two desks? You do not have enough storage as it is. Dump the desks in favor of lap-tops - portable offices which have the added benefit of integrating, in real time, with your communications system.

Three airlocks? At most two. I assume the connecting airlock between the suit module and habitat is designed with 4-way access hatches/ports. Maybe even six?

The inflatable is described as four meters (12.8 feet) in diameter. Two meters of regolith on top of that. Then you want to mount the solar arrays on top of that. . . Very difficult to access for additions or maintenance. Also not very good for thermal effects on solar cells. Recommend mountimg PVA's on risers some distance away from habitat.

All in all though a pretty good start!

Dust Mitigation Concept

For such a small habitable volume, it is imperative the air be kept as free of lunar dust as possible. The nature of lunar dust makes it a prime candidiate for silicosis if breathed for too long.

The simplest method of dust mitigation is to neutralize the dust on space suits before opening airlocks to expose the interior to dust tracked in. Very simply, spray the suits and airlock down with a light water spray. this has the same effect inside the airlock that rain has on a dusty day: water and dust are essentially attracted to each other.

The water used in this application need not be part of the habitat's potable (drinking) water. Instead, a supply of water for these spray-downs can be allocated in a sepatate supply. It is kept sealed in a tank under the airlock floor or above the airlock ceiling.

Prior to entering the airlock from the outside, the astronauts would brush excessive dust off their suits. After closing the airlockl and filling it with air, omnidirectional sprays would wash down trhe entire airlock. The water/dust would wash into a drain that leads to a dust trap and filtration unit. The dust is collected in this trap while the water is returned tom the storage tank. Filtering the dust out of the water prevents the dust particles from abrading the insides of the pumps used in the system. Saves a maintenance headache.

This particular approach should not be confused with suit cleaning. That is an entirely different process involving disassembly of the suit and cleaning the interior as well as exterior elements. It is assumed here the EVA program allows for suit maintenance on a regular schedule in between surface work.

As a side option, the same airlock could be used for hygiene showering as well, but not with the water used for dust control. Showering presupposes the use of organic soaps which would create a soap scum containing hair, skin, body oils etc. This would build up contaminant issue over time.
