- Abstract
- This document serves to provide design guidance for Direct Digital Control (DDC) based Building Automation Systems (BAS). It also provides instructions to design engineers for the BAS design. Explanations of general design philosophy, current unresolved problems confronting the application of DDC in BAS, and considerations for choosing alternative control strategies in specifying application programs are given. This guide is intended for use by GSA and contract designers as a means of identifying major aspects in DDC based BAS design where new construction or major renovations of control systems are included.
