Demand Control Ventilation Requirements Proposed for ASHRAE 90.1
New requirements for demand control ventilation in single zone systems are contained in a proposed addendum to the ASHRAE energy conservation standard.
ANSI/ASHRAE/IESNA 90.1-2001, Energy Standard for Buildings Except Low-Rise Residential Buildings provides the minimum requirements for the design of energy efficient buildings. The standard is written in mandatory language and is intended for code use.
