Building Automation & Physical Security

HVAC, access control, video and fire panels converged with the enterprise estate — and a PoE lighting question most pilots never ask.

Also known as BAS, Lenel, PoE Lighting, Access Control

Left to right is time. Each row is one of the 8 disciplines this one worked alongside, ordered so kindred disciplines sit next to each other rather than alphabetically — a landscape only means anything if neighboring rows belong together. Height is the work running in that domain in that year, weighted by what failure would have cost — life-safety ×3, a statutory obligation ×2.2, the estate itself ×1.5, an evaluation ×1. Every project declares which of those it was, so each ridge traces to an entry you can open and disagree with. Only the work that used this technology is counted, so what shows here is the company it kept rather than the record around it. Height and color are on the record-wide scale rather than this page’s own, so a modest estate draws a modest landscape and any two of these pages can be read against each other.

Building automation architecture for the Medical Examiner’s Office and the Ed Austin State Attorney’s Office, converging HVAC, access control, video, and fire and emergency panels with the enterprise IT estate. Lenel access control throughout.

Later, a PoE lighting feasibility pilot with GraceMark Consulting against a specific question: whether a building could move to PoE lighting without stranding the legacy lighting already installed, and whether both could be driven from the same automation layer. Lighting is rarely replaced all at once, so the interesting problem is not the new fixture — it is whether new and old can be operated as one system while the estate transitions.

Once lighting rides on the network it stops being an electrical system and becomes an endpoint estate, with everything that implies for addressing, power budgeting, segmentation and who owns the change window.

Instrumented plant, metering, roadside and building devices reporting over a network — the practice the term was coined for, two decades before it had the name.
