#About HNQAP
HNQAP (Heat Network Quality Assurance Publications) is an open project for quality assurance of heat networks and low-carbon building services. It began as a set of open procedures, forms and database functions for acceptance testing and KPI calculation, and now publishes the data standard and KPI reference that sit underneath them.
The project builds only on open technologies: MQTT to move data, PostgreSQL with TimescaleDB to store it, and Grafana or any other tool to view it. Nothing in HNQAP needs a licence fee or proprietary hardware.

#Maintainers
HNQAP is maintained by Heatweb Solutions Ltd, a heat network engineering company, and is generated from the KPI catalogue and vocabulary registry of the platform Heatweb runs. Contributions from anyone are welcome: see Collaborate.
#Independence
HNQAP is not part of, and is not endorsed by, the Heat Network Technical Assurance Scheme. Where the KPI reference describes the scheme's KPIs, it paraphrases the scheme's drafts and states where it has interpreted them. The scheme's own documents remain the authority for the scheme.

#Citing HNQAP
Every release is archived on Zenodo. The DOI
10.5281/zenodo.23647605 always
resolves to the latest version, and each release has its own DOI on that
page. Cite the release you used. The repository carries a
CITATION.cff file,
so GitHub's "Cite this repository" button gives the reference in APA or
BibTeX. For a single KPI, cite its code and page, for example
SS-KPI-07, HNQAP Heat Network KPI Reference, https://hnqap.org/kpis/ss-kpi-07/.
