Heating and Ventilation Planning

Plan where heating and ventilation ductwork will be located and how it might affect floor joists and wall insulation values.

Use low-noise source exhaust fans.

Consider the use of heat recovery ventilation as an energy efficient means of providing required ventilation.

Consider installing additional heating ducts close to the floor in parts of an unfinished basement that might be finished in future.

Consider installing an exhaust duct to an exterior wall cap for a future basement bathroom.
