I see a lot of pages and blogs here regarding Green initatives and cost reduction strategies.
I have begun specifying a control package on some of the kitchen ventilation packages I design, that saves energy by reducing the kitchen exhaust hood's airflow. This saves electrical energy and loweres the amount of the air conditioned and heated air being drawn out of the building.
If you know anyone who has interest in this, I could explain fully.
As always, I'm happy to answer any kitchen ventilation questions.
