Overview
Credit: 3 PDH
Length: 45 pages
Natural ventilation refers to the process of exchanging warm building air for cooler outside air without the use of energy-consuming mechanical devices, such as fans and air conditioners. With an increased awareness of the cost and environmental impacts of energy use, natural ventilation has become an increasingly attractive method for providing acceptable indoor environmental quality and maintaining a healthy, comfortable, productive indoor climate. In favorable climates, natural ventilation can be used as an alternative to air-conditioning systems, saving 10%-30% of total energy consumption.
Natural ventilation is not always as simple as just providing multiple operable windows in a building. Wind patterns specific to the site and the building design and its arrangement play a vital role. Care must be taken to avoid having a wind tunnel effect in areas of the building. Excessive wind indoors can obviously provide an undesirable effect, such as in offices where paperwork is lying around on desks.
This 3-hour course outlines the basic principles underlying natural ventilation, and explains how best to proceed with a specific design. It is not intended to be a textbook of natural ventilation; the main aim is to help engineers understand how to incorporate natural ventilation into the design of their buildings.
This course is aimed at Mechanical and HVAC engineers, Architects, Building designers, Energy Auditors, Facility managers, Operational & Maintenance Personnel, and others who are interested in learning about the methodology, benefits and challenges associated with natural ventilation.
