课程名称：建筑中的通风、生命安全与烟雾排放 课程概述： 本课程强调通风在维护室内空气质量中的关键作用，特别是在共享空间如办公室环境中。通过一个办公室的例子，介绍了许多人持续呼吸所带来的二氧化碳释放问题，从而需要不断引入新鲜空气以防止空气稀释。课程深入探讨自然通风系统，揭示堆积效应和风效应的机制。这些概念不仅有助于了解建筑物迎风侧与背风侧之间的压差计算。 课程大纲： 1. 通风与生命安全模块： - 介绍通风对维护室内空气质量的重要性，通过办公室的例子说明如何持续引入新鲜空气。 - 探索自然通风的工作原理，包括堆积效应和风效应的驱动机制，帮助计算建筑物不同侧的压差。 - 理解机械通风系统的基础知识及其相较于自然通风的优缺点，帮助根据需求选择合适的通风系统。 - 学习如何计算给定应用的通风设备容量，并了解商业建筑中生命安全系统及其组成部分的重要性。 - 关注楼梯加压系统对于建筑物人员安全的重要性，了解如何通过样例计算估算所需设备容量，以便在紧急情况下安全撤离。 2. 烟雾排放系统模块： - 理解电梯井及电梯厅加压系统的重要性，在火灾紧急情况下保证安全撤离并保护生命与财物安全。 - 学习国家建筑规范（NBC）和美国暖通空调工程师学会（ASHRAE）对电梯井和电梯厅加压系统的标准。 - 深入探讨空气泄漏及来自电梯厅和电梯井的空气增益，帮助确定加压风扇的容量计算。 - 了解烟雾对生命的危险及烟雾排放系统的重要性，探索烟雾排放系统的各个组成部分及设计时的规范要求。 - 熟悉设计烟雾排放系统时需遵循的最低要求，以及适用于车库、办公室和中庭等不同空间的设计原则。 完成本课程后，学习者将能够进行大型项目的空气流量和楼梯加压计算，并熟悉烟雾排放系统的标准、规范及计算方法。
Name:Ventilation, Life Safety
Description:This module begins the importance of Ventilation to maintain the Indoor Air Quality. Significance of ventilation can explain with an example of any office space, where many people are working together. As we know people are continuously doing respiration in which they are consuming oxygen and constantly releasing carbon dioxide diluting the indoor air constantly. To maintain the quality of indoor air, fresh air needs to be introduced continuously. The module delves how the natural ventilation works and how Stack effect and Wind effect drive the Natural Ventilation. This concept is useful to calculate pressure difference between windward and leeward sides of the building The module explores the basics of Mechanical Ventilation System and its merits and demerits over the Natural ventilation based on application. It will be help full to select ventilation system as per requirement. Learners will calculate the ventilation equipment capacity for given application using air flow rate calculation methods & learn the need of Life Safety System in Commercial building and its various component. The module extends its focus to significance of Staircase Pressurization System for building occupant life safety. This will help to create pressurization in staircase which make pave to evacuate from building in emergency. Learners will understand very fascinating topic that how to arrive the required equipment capacity by understanding given sample calculation for given building layout. It will help to select equipment to match design condition. After completion of this module learners will familiar to carry out air flow rate & staircase pressurization calculation based on L & T experience on very large project.
Name: Smoke Extraction system
Description:The module begins with understanding significance of the Lift Well and Lift lobby pressurization system. Lift well & lift lobby pressurization system maintain safe exit during any fire emergency & save commodity and life. Students will acknowledge what National Building Code (NBC) and American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) says about the Lift Well and Lift Lobby Pressurization system. This will help students to be familiar with these standard and design Lift Well and Lift Lobby Pressurization system as per standard. The module delves into various air leakages and air gains from/to the lift lobby and lift well which help to arrive the capacity of pressurization fan. This will help to calculate total air leakage & select fan capacity to maintain standard pressurization in lift lobby and lift well. Student will come to how smoke is dangerous the occupant life and why smoke extraction system is so much important. The module explores the various component of Smoke Extraction system and code requirement while designing this system. Student will familiar with National Building Code (NBC) to design smoke extraction system. Students will understand minimum requirement for designing smoke extraction system for various spaces like Cark Park, Office spaces, Atriums, etc. After completion of this module students will familiar to carry out lift well & lift lobby pressurization calculation based on L & T experience on very large project. Also, students will aware of smoke extraction system standards, codes & calculation for car park, office space & attriums.
This course underscores the critical role of ventilation in maintaining indoor air quality, particularly in shared spaces like office environments. Using the example of an office space where numerous individuals continuously respire, the constant release of carbon dioxide necessitates a consistent introduction of fresh air to prevent air dilution. The natural ventilation system is explored in-depth, unraveling the mechanisms of the Stack effect and Wind effect. These concepts are not only instru
