What are the principles of Lev in construction?

Local exhaust ventilation (LEV) is one such engineering control measure.

What is balanced ventilation?
A balanced ventilation system is one where fresh air is drawn in at the same rate that stale air is vented out of the building. In a typical design, fresh air enters the high-occupancy areas like living rooms and bedrooms. Stale air is vented out through bathrooms, kitchens and other less-occupied areas.
