14. Carbon Monoxide Testing Problem –Habitat was concerned that the design of the house was causing a problem with CO build up. –Dryer Exhaust may create a vacuum. –Hot water heater has an open flue. –House too ‘tight’.

15. Carbon Monoxide testing.

16. Carbon Monoxide Testing Testing –Tested two houses. –Max CO level was 3ppm. –Max allowable concentration in living area is 9ppm (ASHRAE). –Testing concluded no problem in design.

17. Carbon Monoxide Testing Engineering Model –Model dryer and house to support testing. –Flow from Dryer. –Air circulation in house.
