Clima 2007 WellBeing Indoor Congress took place in Helsinki on June 10-14, 2007. It was attend by over 1000 participants who presented almost 500 papers. The 9th REHVA World Congress offered scientists, industry, building owners, consultants, engineers, architects and policy-makers a platform for the exchange of scientific knowledge and technical solutions. The congress covered all the aspects of HVAC technology including building automation in all types of buildings.

The next Clima Congress will be held in Antalya, Turkey on May 9-12, 2010. Click here for more information.

The Proceedings of the Congress are available for purchase. The Proceedings contain 465 papers including the key-note lectures. They are available as and Abstract Book and a CD ROM containing the full papers.

The technical quality of the papers is good. They cover well the scope of the Congress and have been allocated into 30 technical sessions.

Proceedings table of contents

The Price of the Proceedings CD ROM and Abstract Book is 100 euros. A mailing and handling fee of 20 euros will be added. Printed Proceedings are also available (6 books, 3900 pages) at a price of 150 euros + mailing costs. For orders please contact helka.backman@sisailmayhdistys.fi.
