Manufacturer Installation Guide

ISO 14644-1

Clean rooms require HEPA (99.97% @ 0.3 micron) or ULPA filtration. Standard fiberglass filters are pre-filters only and cannot achieve the particle counts required for any clean room classification.

LEED v4 EAc1 — Enhanced Commissioning / ASHRAE Guideline 36

Enhanced LEED commissioning requires post-occupancy trend data collection to verify systems continue to operate as designed after the building is occupied. Without trend data, there is no evidence that control sequences are performing correctly under actual load conditions. A minimum of 10 months of seasonal performance data is required.

LEED v4 EAp1 / ASHRAE Guideline 0-2019

Enhanced LEED commissioning requires an independent commissioning authority (CxA) — not the installing contractor — to verify all systems meet design criteria. The CxA must review submittals, witness testing, and document that systems perform per the Owner's Project Requirements (OPR). Without independent verification, LEED commissioning credits cannot be claimed.

Manufacturer Installation Guidelines

Thermostat wire connections should use proper terminal blocks or crimp connectors, not wire nuts. Wire nuts on 18 AWG thermostat wire often lose connection over time due to vibration.

NEBB / AABC Procedural Standards

All TAB work must be documented on proper report forms recording design CFM, measured CFM, and final adjusted CFM for every outlet. Without documentation, the work cannot be verified or submitted to the engineer for approval.

NIST SP 800-82 / ASHRAE Guideline 36 — Cybersecurity

BAS controllers must be on a segregated network (VLAN or separate physical network) with firewall protection from general IT traffic. Default passwords must be changed, and access should be restricted to authorized personnel. NIST SP 800-82 provides cybersecurity guidelines for industrial control systems. Unsecured BAS devices have been exploited in real attacks to disrupt building operations and gain access to corporate networks.
