Hybrid Ventilation – a design guide

Peter van den Engel - 2023

The book was first issued in 2019. June 2023 a new version of this book is placed on the site.

More attention is payed to

  • Covid and ventilation (new)
  • Openable windows and grids, how and when to use?
  • Energy use of ventilation systems
  • Elementary calculation software

The aim of the book is to give an overview of the advantages, history and principles of hybrid and mixed mode ventilation. Natural ventilation plays a key role to improve comfort and reducing energy. In order to make natural ventilation successful, an early integration in the design-process is necessary. In the long term fully natural ventilated buildings are expected to become the standard, even in high rise buildings (Wood 2013). However, much more scientific development is necessary in order to guarantee that these buildings will behave as expected. The book is not an advertising book for natural ventilation. In many cases natural ventilation alone for climate control is not possible. However, in most of the cases hybrid or mixed mode types can be applied and these options need more attention. Adaptive thermal comfort is closely related to hybrid and mixed mode buildings in which a wide range of temperatures are possible, with substantial options of saving energy (Humphreys 2015). Designing natural, hybrid or mixed mode buildings requires a complete other way of thinking about design. It is partly a mixture of mechanical, building physical and architectural engineering, but it is also more. Knowledge about natural air flows and designing with natural air flows is in fact a new profession, for which this book gives a general, and sometimes detailed, outline.

In 1995 promoveerde Peter van den Engel op het proefschrift Thermisch Comfort en Ventilatie-efficiency door Inducerende Ventilatie via de Gevel. Het proefschrift is te downloaden via de Repository van de TU Delft. Voor degenen die een gedrukte uitgave van Hybrid Ventilation bestellen is gratis een gedrukt exemplaar van dit proefschrift beschikbaar.
