The Definitive Guide to the 2014 NEC Completely revised and expanded to reflect changes in the 2014 NEC, McGraw-Hill's National Electrical Code® 2014 Handbook, 28th Edition presents the trusted advice and analysis you need to accurately interpret 2014 NEC rules. In-depth coverage of the background and rationale for specific Code rules enhances your understanding of the meaning and application of those rules. This practical resource also points out important matters of discussion with inspectors. Designed as a must-have companion to the 2014 NEC book published by the National Fire Protection Association, this comprehensive volume features more than 1,000 detailed diagrams and photos. The authoritative information and insight contained in this on-the-job reference will help your work pass inspection the first time. This book doesn't duplicate the text of the NEC. Instead, it is entirely comprised of explanatory text, specifically addressing every single code article, providing the most analytical content available. Because this book is published completely independently from NFPA, it is free to--and frequently does--offer detailed analysis of technically questionable and editorially convoluted provisions in the NEC, along with strategies for discussing those issues in advance with owners and inspectors before financial commitments are made. Covers all significant changes in the 2014 NEC, including: Low Voltage Direct Current Distribution Systems (new Article 393) Modular Data Centers (new Article 646) Fire Resistive Cable Systems (new Article 728) Energy Management Systems (new Article 750) Global changes to hazard warning labels and centralization of rules for lockout mechanisms, along with extensive increases of permitted utilization voltage from 600 to 1000 Coverage throughout the NEC® of DC systems due to expanding usage Critical expansion of both requirements for and acceptable strategies to provide AFCI protection

ASHRAE Research: Improving the Quality of Life ASHRAE is the world’s foremost technical society in the fields of heating, ventilation, air conditioning, and refrigeration. Its members worldwide are individuals who share ideas, identify needs, support research, and write the industry’s standards for testing and practice. The result is that engineers are better able to keep indoor environments safe and productive while protecting and preserving the outdoors for generations to come. One of the ways that ASHRAE supports its members’ and industry’s need for information is through ASHRAE Research. Thousands of individuals and companies support ASHRAE Research annually, enabling ASHRAE to report new data about material properties and building physics and to promote the application of innovative technologies. Chapters in the ASHRAE Handbook are updated through the experience of members of ASHRAE Technical Committees and through results of ASHRAE Research reported at ASHRAE conferences and published in ASHRAE special publications, ASHRAE Transactions, and ASHRAE’s journal of archival research, Science and Technology for the Built Environment. For information about ASHRAE Research or to become a member, contact ASHRAE, 1791 Tullie Circle, Atlanta, GA 30329; telephone: 404-636-8400; www.ashrae.org. Preface The 2015 ASHRAE Handbook—HVAC Applications comprises more than 60 chapters covering a broad range of facilities and topics, written to help engineers design and use equipment and systems described in other Handbook volumes. Main sections cover comfort, industrial, energy-related, general applications, and building operations and management. ASHRAE Technical Committees in each subject area have reviewed all chapters and revised them as needed for current technology and design practice. An accompanying CD-ROM contains all the volume’s chapters in both I-P and SI units. This edition includes two new chapters: • Chapter 61, Smart Building Systems, covers smart systems and technologies for automated fault detection and diagnostics, sensors, and actuators, and the emerging modernized electric power grid and its relationship to buildings and facilities. • Chapter 62, Moisture Management in Buildings, addresses avoiding or reducing risks associated with damp buildings, with suggestions for architectural and HVAC system design, operation, and occupancy. Other selected highlights include the following: • Chapter 1, Residences, has updated guidance on duct system design and communicating control systems. • Chapter 4, Tall Buildings, has new content on supertall and megatall buildings; improved stack effect discussion and calculations; and new information on chilled beams, code references, split central plants, and elevator shaft pressurization. • Chapter 7, Educational Facilities, provides new design criteria updated for current standards, a new section on energy measurement and verification, and a newly compiled list of case studies from ASHRAE Journal. • Chapter 8, Health Care Facilities, has been extensively revised to ANSI/ASHRAE/ASHE Standard 170-2013, with new content on regulatory resources, hospital-acquired infections, sustainability, and operations, and expanded text on control measures, outpatient care, isolation and bronchoscopy rooms, plus research results from RP-1343 on heat gain from imaging systems. • Chapter 16, Laboratories, includes updates on applying usage factors, pressurization control, and energy efficiency measures. • Chapter 18, Clean Spaces, has extensive new content on demand control, computational fluid dynamics analysis, pharmaceutical manufacturing facilities, safety, environmental systems, installation and testing, and sustainability and energy conservation. • Chapter 19, Data Centers and Telecommunication Facilities, has been completely rewritten for current best practices as in the ASHRAE Datacom Series. • Chapter 33, Kitchen Ventilation, was updated for the latest revisions to relevant standards, with new sections added on commissioning and the design process (for the first-time designer), and the chapter content restructured to reflect the sequence of the design process. • Chapter 34, Geothermal Energy, has significant new content and examples on ground-coupled heat pump systems design, hybrid ground-source heat pumps, piping, pressure considerations, purging, deep boreholes, central plants, open-loop/surface-water direct cooling, and simulation. • Chapter 35, Solar Energy Use, has revised examples and figures, plus new content on solar-combi systems; design, control, and operation of solar cooling; and grid-connected photovoltaic systems. • Chapter 49, Water Treatment, has major revisions on corrosion, deposition, microbiological growth and control, filtration and closed-loop systems, alternative water sources, Legionnaires’ disease, thermal storage, and steam boiler systems. • Chapter 50, Service Water Heating, describes new technologies for hot-water generation and distribution and reducing consumption at end-use fixtures. • Chapter 53, Fire and Smoke Control, has been revised to align with ASHRAE’s Handbook of Smoke Control Engineering, with many new figures and examples. This volume is published, as a bound print volume and in electronic format on CD-ROM and online, in two editions: one using inch-pound (I-P) units of measurement, the other using the International System of Units (SI).
