Preface

The 2011 ASHRAE Handbook—HVAC Applications comprises over 60 chapters covering a broad range of facilities and topics, and is written to help engineers design and use equipment and systems described in other Handbook volumes. ASHRAE Technical Committees have revised nearly every chapter to cover current requirements, technology, and design practice. An accompanying CDROM contains all the volume's chapters in both I-P and SI units. This edition includes two new chapters:

• Chapter 4, Tall Buildings, focuses on HVAC issues unique to tall buildings, including stack effect, system selection, mechanical room location, water distribution, vertical transportation, and life safety.

• Chapter 60, Ultraviolet Air and Surface Treatment, covers ultraviolet germicidal irradiation (UVGI) systems and relevant guidelines, standards, and practices, as well as energy use and economic considerations. Here are selected highlights of the other revisions and additions:

• Chapter 3, Commercial and Public Buildings, now covers office buildings, transportation centers, and warehouses and distribution centers, with new sections on commissioning, sustainability, energy efficiency, energy benchmarking, renewable energy, value engineering, and life-cycle cost analysis.

• Chapter 7, Educational Facilities, has added content on higher education facilities, commissioning, dedicated outdoor air systems (DOAS), combined heat and power (CHP), and sustainability and energy efficiency.

• Chapter 8, Health-Care Facilities, has been updated to reflect ASHRAE Standard 170-2008 and has revised discussion on design criteria for pharmacies.

• Chapter 18, Clean Spaces, has updated content on standards, filters, barrier technology, and sustainability plus a new section on installation and test procedures. Chapter 19, Data Processing and Telecommunication Facilities, has a new title and revised and/or new content on design temperatures, change rate, humidity, power usage effectiveness (PUE), aisle containment, economizer cycles, and computer room airhandling (CRAH) units.

• Chapter 33, Kitchen Ventilation, largely rewritten, covers key sustainability impacts and recent research results.

• Chapter 34, Geothermal Energy, has updated tables and graphs, with new, step-by-step design guidance on vertical systems, and expanded content on hybrid systems, ISO rating, and system efficiency.

• Chapter 36, Energy Use and Management, has updates on ASHRAE's Building Energy Quotient (eQ) labeling program.

• Chapter 40, Computer Applications, updated throughout, has new content on building information modeling (BIM) and wireless applications.

• Chapter 41, Building Energy Monitoring, has a new section on simplifying methodology for small projects.

• Chapter 42, Supervisory Control Strategies and Optimization, has been reorganized, with new content on thermal storage and thermally active building systems (TABS), hybrid cooling plants, and predictive control.

• Chapter 43,HVACCommissioning, has been updated throughout to reflect ASHRAE Guideline 1.1-2007.

• Chapter 44, Building Envelopes, has reorganized and expanded content on nonresidential and existing buildings, durability, and common building envelope assemblies.

• Chapter 48, Noise and Vibration Control, has a new title plus reorganized and new content on noise criteria, chiller noise, and vibration measurement.

• Chapter 50, Service Water Heating, has expanded content on sizing tankless water heaters plus new data on piping heat loss.

• Chapter 55, Seismic- and Wind-Resistant Design, has a new title and reflects changes to building codes, standards for anchor bolt design, and other new requirements.

• Chapter 57, Room Air Distribution, has extensive new application guidelines plus new content on indoor air quality (IAQ), sustainability, and chilled beams.

• Chapter 59, HVAC Security, has a new title, with updates from ASHRAE Guideline 29-2009 and new sections on risk evaluation, requirements analysis, and system design.

This volume is published, both as a bound print volume and in electronic format on a CD-ROM, in two editions: one using inchpound (I-P) units of measurement, the other using the International System of Units (SI).

Corrections to the 2008, 2009, and 2010 Handbook volumes can be found on the ASHRAE Web site at http://www.ashrae.org and in the Additions and Corrections section of this volume. Corrections for this volume will be listed in subsequent volumes and on the ASHRAE Web site.
