2. air quality made simple Ventilation and IAQ 1.Do nothing and rely on windows and leakage to exhaust odors, contaminants and moisture. 2.Use spot fans to intermittently ventilate bathrooms. 3.Use central ventilation systems to intermittently ventilate bathrooms (and other trouble areas). 1.Do nothing and rely on windows and leakage to change air in to/out of the home. 2.Introduce fresh air into the home through a forced air system intermittently by way of a damper or HRV/ERV. 3.Introduce fresh air into the home through a forced air system continuously by way of a High Efficiency AHU with DC motor control. Ventilation Options (spot) IAQ Options (air changes) Ineffective (especially in tightly sealed energy efficient homes) Loud, inefficient, multiple roof penetrations for exhaust Intermittent provision of fresh air, inefficient, somewhat effective Silent, efficient, effective, one roof penetration for exhaust (but still need IAQ) Continuous removal of air from common areas (but still need bathroom exhaust)

3. air quality made simple Ventilation and IAQ BEST Combine Ventilation and IAQ with a high efficiency balanced continuous ventilation system. Highly effective removal of stale air from trouble areas, silent, efficient, increased comfort and huge IAQ benefit from continuous low volume air changes.

8. air quality made simple HRV Connected to HVAC System 1. Conditioned air is removed from the common areas of the home through the HVAC return. 2. The conditioned air is then used to treat the incoming fresh air which is then distributed through the home using the supply ducts. The bathrooms still need ventilation The air change is intermittent A separate control interlink must be added to meet ASHRAE 62.2 AHU

9. air quality made simple Continuous Ventilation with Energy Recovery Ventilator Stale humid air is continuously removed from the bathrooms and kitchen and then used to condition the fresh air being brought in. The conditioned fresh air is fed back into the house. Fresh air is brought into the HRV/ERV from outside the house Stale air (containing odors, mold causing moisture and VOC’s) is exhausted from the house!

10. air quality made simple Click Here for online video demonstration Continuous Ventilation with HRV and On Demand Boost 1. Each Bathroom has a motorized damper with a self balancing Continuous Airflow Regulator integrated in the door of the damper. This provides continuous low airflow in accordance with ASHRAE 62.2 2. When someone flips the light switch or timer, the damper door opens and boosts the fan so that high volumes of stale air are removed from the bathroom during use. 1. ZRT in continuous ventilation mode, the damper is closed and the pressure independent/self balancing CAR is holding a steady flow of air. 2. ZRT in demand mode, the damper is open and a micro-switch triggers the fan to boost to high volume evacuation. An optional 2 nd Constant Airflow Regulator may be added in the neck of the ZRT to provide a maximum flow rate while in demand mode operation.

11. air quality made simple Airflow Control The Constant Airflow Regulator “CAR” is the simple solution to balanced airflow. Automatically Balances Airflow Pressure Independent Factory Calibrated Easy Field Adjustable Simple - Plug and Play Install Maintenance Free Controls Airflow for Exhaust, Supply & Return Ducts Save Energy & Increase Comfort Improve IAQ “One of the greatest HVAC innovations ever!”

12. air quality made simple Airflow Control The Constant Airflow Regulator is able to hold a very consistent airflow across a broad range of air pressures. As the air pressure increase the CAR is engineered to restrict airflow to maintain a consistent CFM.

13. air quality made simple Makeup air systems replace the “amount” of air ventilated from a home with “fresh” air from outdoors. Makeup Air Solutions The 3 most common “controlled” methods for introducing fresh air are:  Air Inlets  HRV/ERV/Fan  Make-up Air Through The HVAC ASHRAE 62.2 specifies the effective air change rate as:  Occupancy Rate (# bedrooms +1) = 7.5 cfm/person  Plus Area Rate = 1 cfm/100 sq.ft.

14. air quality made simple Air Inlets –Negative pressure created by mechanical ventilation draws a controlled amount of fresh air into living spaces at the most beneficial locations. Makeup Air Solutions Compared to having air randomly leak into a home through uncontrolled cracks Air Inlets: – Improve Energy Efficiency – Provide Cleaner Air (think about air coming under a door or through an attic/garage) – Provide Greater Comfort by controlling airflow amounts

15. air quality made simple Air Inlets Should Be Used With: –Continuous exhaust ventilation systems –Radiant baseboard or floor heated spaces –Energy efficient “ weatherized ” buildings Makeup Air Solutions Air Inlets Should Not Be Used With: –Forced-air heating (unless supply & return are well balanced) –When outside air is considered unhealthy

16. air quality made simple Makeup Air Solutions Air Inlets Airlets can effective introduce airflow at a consistent rate.

17. air quality made simple Heat Recovery Ventilator - Sensible heat recovery in cooler climates, 60-90% Savings winter. Makeup Air Solutions HRV ’ s and ERV ’ s Energy Recovery Ventilator - Total energy(enthalpy) recovery in warmer humid climates, 50-60%+ Savings year round. HRV/ERV’s are an exceptional means for removing stale humid air from trouble areas such as bathrooms and using it to treat incoming fresh air in tightly sealed energy efficient homes.

19. air quality made simple If forced air heating is available, the FCU or AHU can provide outside makeup air through a fresh air intake into the return duct. Precautions Air is only introduced while the FCU or AHU is running. There is a potential of negatively impacting the performance of or damaging the forced air system.
