, Advanced VAV System Design Guide Preface
Preface
The Advanced Variable Air Volume (VAV) System Design Guide (Design
Guide) provides a powerful new resource for Heating, Ventilation, and Air-
Conditioning (HVAC) designers. It presents brand new information on fan
selection and modeling and provides the most current recommendations on
VAV airside system design.
Total large office building energy savings of up to
12% are achievable by applying the
…a powerful new resource
recommendations in the Design Guide resulting in
for heating,ventilation, and
an estimated annual statewide savings of 2,220
air conditioning designers.
MWh/yr for new large office construction.
The Design Guide is a product of a three-year
research project that included field monitoring of five sites with built-up VAV
systems. It contains measures and recommendations from a range of sources
including our research, associated research1, ASHRAE Guidelines and
Standards, Title 24, team experience gained in the design and commissioning
of mechanical systems and controls for commercial buildings and in
performing peer reviews of mechanical designs of commercial buildings.
Throughout this document we refer to standard practice. This is a subjective
benchmark that is determined based on our experience as mechanical
engineers, reviewing the work of other firms, and through our conversations
with manufacturers and contractors.
The Advanced VAV System Design Guide was developed as part of the
Integrated Energy Systems — Productivity and Building Science project, a
Public Interest Energy Research (PIER) program administered by the
California Energy Commission under contract No. 400-99-013, and managed
by the New Buildings Institute.
The Buildings Program Area within the PIER Program produced this Design
Guide. The program includes new and existing buildings in both the
residential and the non-residential sectors. It seeks to decrease building
energy use through research that will develop or improve energy efficient
technologies, strategies, tools, and building performance evaluation methods.
This document is part of report #P500-03-082 (Attachment A-11 Product
3.6.2).. For other reports produced within this contract or to obtain more
information on the PIER Program, please see Project Reports in Appendix 7,

Publications Unit at 916-654-5200. The Design Guide is also available at
