This paper presents an approach to the design of natural
and hybrid ventilation systems that accounts for
specific climatic and operational conditions and is
organized to serve the building designer at each
distinct phase of design - predesign analysis,
preliminary design, design development, and design
performance evaluation. The approach makes use of: a) a
climate suitability analysis method, presented in a
companion paper, that establishes design ventilation
rates needed for preliminary design calculations; b) the
loop equation design method to estimate preliminary
sizes of system components and control and operational
strategies; and c) detailed multizone coupled
thermal-airflow analysis, using CONTAM97R, for design
development and, ultimately, system performance
evaluation. A representative application, limitations of
the approach, and research needed to support the
approach will be briefly outlined.
