# @maintainable.xyz/house-spec
|
|
|
|
The open specification for building maximally maintainable, healthy homes.
|
|
|
|
## What This Is
|
|
|
|
A complete, opinionated building specification for a Baufritz timber-frame house engineered around **clean-room-level indoor air quality** and **lifetime maintainability**. Every system — air filtration, heating, flooring, wiring — is designed so that components can be inspected, serviced, and replaced without destructive intervention.

## Specification Documents
|
|
|
|
| Spec | Scope |
|
|
|------|-------|
|
|
| [01 — Air System](specs/01-air-system-spec.md) | H13 HEPA whole-house filtration, MVHR, steam humidification, duct design, pressure management |
|
|
| [02 — Sensors & Automation](specs/02-sensor-automation-spec.md) | Per-room air quality sensors, KNX/Zigbee architecture, Home Assistant integration, demand-controlled ventilation |
|
|
| [03 — Baufritz Coordination](specs/03-baufritz-coordination-spec.md) | Technical room, duct routing, airtightness, radon protection, construction checkpoints |
|
|
| [04 — Flooring & Ceiling](specs/04-flooring-ceiling-spec.md) | Lindner NORTEC Doppelboden raised floor, WOODline parquet, Plafotherm AirHybrid radiant ceiling |
|
|
|
|
## Key Design Principles
|
|
|
|
- **Whole-house H13 HEPA** — 99.95% particle capture at 0.3 um, ISO Class 7-8 equivalent
|
|
- **Every air parameter controlled** — particulates, CO2, VOCs, humidity, temperature, pressure, radon
|
|
- **Heating via ceiling** (Plafotherm AirHybrid), not floor — fast response, furniture-independent, integrates MVHR supply air
|
|
- **Raised access floor** (Lindner NORTEC Doppelboden) — individually liftable 600x600 mm panels for full access to services underneath
|
|
- **Dry construction throughout** — no wet trades, ideal for Baufritz timber-frame
|
|
- **Positive pressure** (+3-5 Pa) — unfiltered air never enters the building envelope
|
|
|
|
## PDF Build
|
|
|
|
The specs can be compiled into a single styled PDF with rendered Mermaid diagrams:
|
|
|
|
```sh
|
|
pnpm install
|
|
pnpm build
|
|
# Output: dist/house-spec.pdf

|
```
