A complete 23-section interactive guide adapted from a full-length BMS/BMAS use-case book — one consistent 72,000 sq ft, 3-story office building carried end-to-end across 15 chapters and 7 appendices, from Owner’s Project Requirements through system architecture, HVAC/lighting control design, construction drawings and schedules, bill of materials and costing, installation/commissioning, and operations/handover.
Part I – Project Definition & Requirements: Owner's Project Requirements (OPR) and Basis of Design (BOD) for a single office-building use case. Part II – System Architecture & Design: overall BMAS architecture, controller/server hierarchy, network topology, and BACnet communication. Part III – Detailed System Design: HVAC control strategies for AHUs and VAV terminal units, lighting/power monitoring integration, and alarm philosophy. Part IV – Drawings & Schedules: riser diagrams, floor-level control layouts, panel drawings, and device/IP address schedules. Part V – Bill of Materials & Costing: BOM development and budget-level cost estimates. Part VI – Installation, Testing & Commissioning: installation guidelines, functional performance testing, and owner training. Part VII – Operations, Maintenance & Handover: operator interface design, alarm response, preventive maintenance, and final handover. Part VIII – Appendices: full implementable control sequences, sample RFP language, naming conventions, a cybersecurity checklist, lessons learned, an acronym glossary, and a design package deliverables reference.

The BMAS documented in this guide monitors and controls HVAC (AHUs, VAV terminal units, exhaust/relief fans), energy and power metering, lighting integration, indoor environmental quality, and fire alarm status (monitoring only). Access control, video surveillance, fire alarm control logic, and industrial process automation are explicitly outside this system's scope — worth keeping in mind when applying this use case to a real project.
The guide covers 15 chapters and 7 appendices, following one consistent 72,000 sq ft, 3-story speculative office building from Owner's Project Requirements and Basis of Design, through system architecture, HVAC/lighting control design, construction drawings and schedules, bill of materials and costing, installation and commissioning, and operations/maintenance/handover — plus full implementable control sequences and reference appendices.
The OPR defines what a building system must achieve — performance goals, occupant expectations, and business objectives — independent of any specific implementation. The Basis of Design (BOD) translates those requirements into a concrete technical strategy: system architecture, control philosophy, network assumptions, and design standards used to actually build the system.
BACnet (Building Automation and Control Networking Protocol) is the open communication standard most building automation systems use so that controllers, sensors, and software from different vendors can interoperate. This guide covers BACnet/IP for server-to-controller communication and BACnet MS/TP for zone-level device trunks, including routing between the two.
A Variable Air Volume (VAV) terminal unit regulates the amount of conditioned air delivered to a zone by modulating a damper, with optional electric or hot-water reheat for perimeter zones. Control strategies include occupied/unoccupied operating modes, zone temperature setpoints, and after-hours override with automatic time-limited operation.
A complete BMAS BOM includes controller and device quantities, network hardware, sensors and actuators, and licensing, while the cost breakdown adds labor and engineering effort, programming and commissioning costs, contingencies/allowances, and cost-normalization metrics — giving owners a defensible basis for budget decisions.
