Book Description
"TRB's National Cooperative Highway Research Program (NCHRP) Research Report 836: Guidelines for Emergency Ventilation Smoke Control in Roadway Tunnels presents guidelines for ventilation in roadway tunnels to facilitate human evacuation and emergency responder safety. These guidelines consider tunnel geometrics such as tunnel altitude; physical dimensions (i.e., length, cross section); type of traffic flow (i.e., single or bi-directional flow); and fan utilization and placement. They also consider cargo types and quantities as they pertain to fire heat release rates (FHRRs) and ventilation requirements. The guidelines determine the effects of ventilation on tunnel fires including fire size, and the interaction of firefighting and ventilation system operation. " -- Publisher description

Book Description
The ventilation system at the Eisenhower Memorial Tunnel was studied to determine the most energy efficient means of operation. The tunnel is a twin bore highway facility 8,940 feet long having a fully transverse ventilation system. Of the four mechanisms responsible for natural ventilation (piston effect, barometric pressure differentials, chimney effect, and outside wind effects) only the piston effect was found to be reliable. The TUNVEN computer model was found to be an excellent tunnel design and analysis tool. Through its application, a seasonal variation in airflow caused by icing in the flues was discovered.

Book Description
This book illustrates a new quantitative risk analysis model for road tunnels that is capable of evaluating the role of infrastructure measures, equipment and management procedures as prescribed by EU Directive 2004/54/EC. The risk assessment draws on the typical F-N curves of societal risk, evaluated with the help of event tree analysis, vehicle queue formation dynamics, and users’ egress and tenability models. In addition, the model considers the reliability of the safety measures. The work provides essential guidance on the following aspects: how a quantitative model can be implemented to evaluate risk in road tunnels; how to build an event tree for the accident scenarios considered; how to simulate the vehicle queue formation; how to simulate the evolution of accident scenarios; and how to simulate the users’ egress. Given its scope and depth of coverage, the book will be of interest to all engineers whose work involves fire protection and safety in tunnels, all persons engaged in safety and transport engineering or risk analysis for road tunnels, as well as public and private bodies involved in the application of Directive 2004/54/EC.

Book Description
This book is an attempt to combine all the books, literatures, researches and universities masters theses available for a shortcut fundamental knowledge to design basic passive or natural ventilation in residential homes. As in-depth studies in passive design will take years of immense work due to so many variables involved, we tried to gather just enough information to provide you the basic working knowledge to start designing your simple naturally ventilated project. We also included our NV study of a high-rise building that was successfully built.
