The Pitfalls Of Pressurization Smoke Control Systems

August 29, 2016

By Mike Ferreira, PE, Vice President Development One of the primary objectives of the model building codes is to minimize the impact of fire, including reducing to the greatest extent possible the spread of fire and smoke floor-to-floor. This objective is achieved using a combination of building fire safety features, including passive fire/smoke separations and

Hydraulic Modeling and Dynamic Open Flow Calibration

May 29, 2016

By Phil Smith, Project Manager and Chen-Hsiang Su, PE, Senior Consultant, Lincolnshire, IL, JENSEN HUGHES A hydraulic model is a computer program configured to simulate flows for a hydraulic system. The system could be a sprinkler system, a firewater distribution system, or oil pipeline, etc. for either an existing network or one in development. The primary purpose for

Ambient Attention: An Array of Conditions in Industrial Occupancies Can Affect the Performance of a Fire Alarm System

April 26, 2016

by Wayne D. Moore THE AMBIENT CONDITIONS PRESENT in industrial occupancies present challenges for the placement of detection devices and audible notification appliances for a fire alarm system. The 2016 edition of NFPA 72®, National Fire Alarm and Signaling Code, states the limits imposed on these devices based on ambient conditions, and designers must carefully

The Design Fire: Selecting Fire Characteristics for a CFD Model

April 18, 2016

By David Stacy and Adam Edwards One of the most valued services fire protection engineering consultants can provide a client is the use of fire modeling as part of a performance-based design (PBD) approach. The PBD approach can save valuable project budget as well as provide a more complete design that provides an equivalent, if

Addressing lab design trends: Part 1 – Atriums and vertical openings

March 17, 2016

By Simon Goodhead, Director Atlanta office and Jeremy Lebowitz, Director of Development for Laboratory and Industrial, JENSEN HUGHES At the 2015 Laboratory Design Conference two distinct themes arose: 1) new development of new lab buildings is slowing, resulting in more reuse and alteration projects to existing labs; and 2) daylight and vertical integration is a

How Reliable Is Your Smoke Control System?

March 17, 2016

By Mike Ferreira, PE, Vice President Development Will my smoke control system work properly during a fire? That is the question all building owners/operators should ask themselves. Smoke control systems are unique in that they often sit dormant (sometimes for years) and problems that can affect their operation may not be identified until it is

Getting the Best Fire/Life System System You Can

March 17, 2016

Last part of 4-part article on anticipating and responding to upgrades in fire/life safety systems By Scott M. Golly and Alan J. Kouchinsky September 2015 If you are being forced to upgrade a system due to obsolescence, don’t assume you cannot afford to add better functionality. For example, voice fire alarm systems offer far greater

Understanding Advances in Technology, When to Upgrade
