Electronic Access Control, Second Edition provides the latest advice on how to interface systems from multiple Electronic Access Control (EAC) manufacturers into a single cohesive system. The book shows how to provide integration, while also allowing building security managers to protect, control and manage their own users’ card data. This second edition details advanced card data management and advanced system access level management. Readers will be better able to manage their systems to protect the privacy of their cardholders’ private information, while providing much improved control over the security of their buildings. Like its highly regarded first edition, the book offers the complete picture on EAC for readers at any level of expertise. It provides comprehensive material on how to select, and interface to, the appropriate locking hardware, typically the most difficult responsibility for access control system designers, installers and end users. Provides a comprehensive understanding of Electronic Access Control (EAC) Systems to readers at any level, novices and experts alike Helps readers understand concepts for securing a facility, while providing transparent access to those who frequently, and legitimately, enter the facility Includes expanded information on system configurations, including user data security, access levels, access clearances and groups, and system interfaces Offers all new material on how to interface systems from multiple manufacturers into a single cohesive system

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). Corrections to the 2012, 2013, and 2014 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. Reader comments are enthusiastically invited.
