During the launch of our e3-initiative and the following seminars in Europe, we had the opportunity to meet representatives from consultants, contractors end end-users. All with a great interest for energy efficient and environmentally friendly air handling solutions in common. Several interesting discussion were held, and in many of them the same questions came up every time. We have therefore decided to launch this Q&A section as a service for all who have an interest in this area. You are also welcome to send in your own questions to our energy experts at energyexpert@flaktwoods.com.
