With 26,000 hard copies and hundreds of downloads of the first edition in circulation, this popular guide has been an indispensable resource for the industry since 2011.

Waterloo has now updated 48-page second edition of The Green Book to include everything required by HVAC consultants, engineers and architects to incorporate air diffusion into their projects.

The publication is packed with information on air diffusion, including comfort criteria and acoustic information, as well as terms, definitions and symbols. In addition, there is information on conventional air diffusion patterns and a simple product selection guide.

While Waterloo uses its products for illustration purposes, this unbiased guide provides important performance data to make it easier to choose the right product for the project. 

John Tiernan, managing director at Waterloo, said: “We believe it’s important to share knowledge within the industry. As part of our commitment to collaboration we provide HVAC consultants, architects, engineers and developers with information on air distribution, so they can create the right environment through good air flow.”
