2. What is Ventilation? “Providing for acceptable indoor air quality (IAQ) through the simultaneous exhaust of stale air and supply of fresh outdoor air.” In with the good! Out with the bad!

3. Why Ventilate?

4. Why Manage Humidity? Constant Temperature (40-100 F) Moisture Prerequisites for Microbial Growth Source of Spores + + + + + + = = IAQ Solutions - HUMIDITY CONTROL

5. ASHRAE-recommended Comfort Problems Organic Growth 01020 30 40 50 60 70 80 90100 Percent Relative Humidity, % RH HUMIDITY CONTROL

6. Why Ventilate?  Protect your families health.  Protect your home.  Provide a comfortable home environment.  Homeowners place high value on ventilation!

7. Contractors - Why Ventilate?  To reduce call-back problems  To make more money

8. Attributes of Good Ventilation  Ample installed air flow  Pressure balanced – both exhaust and fresh air blowers  Quite operation  Energy efficient  An engineered appliance

9. Attributes of Good Ventilation

10. Sound insulation No condensate drain ARI Certified zero exhaust air recapture Fixed Plate PLUS Sensible AND latent heat transfer No defrost control or heat required Good overall energy efficiency No moving parts RenewAire’s Answer Humidity control

11. ERVs verses HRVs  Heat Recovery Ventilators (HRVs) transfer temperature differential only   Aluminum and plastic plate exchangers and heat pipes   Good for high humidity and high temperature applications   Positive air stream separation   Not often used for general building ventilation because of low efficiency

12. Venmar Constructo 1.5 Complex hanging kit Condensate drain kit Re-circulation defrost damper shuts off OA and allows exhaust air back to the home Sensible transfer core or ERV at a substantial price adder

13. ERVs verses HRVs  Energy Recovery Ventilators (ERVs) transfer temperature and humidity differential   Desiccant wheels and enthalpic plate units   Best in cold climates and hot humid climates   High temperature and humidity transfer efficiency   Not used for indoor pools etc.

14. Air-X-Change Diameter sweep seal - leakage results in cross- contamination Blower section Polyethylene wheel with silica-gel desiccant Circumference seal - leakage results in bypass air and lowered efficiency

15. HVI  Testing and certification of ERVs up to 400 CFM  Unit performance Air flow -static capabilities Sensible and total efficiency Cold temperature survival

29. Aprilaire TM Research Products Corp. One model only No controls - plug in and runs constantly Core air paths not straight - can act like filter Porous plates transfer pollutants along with water Blow-thru design means blowers not filtered

30. RenewAire verses Aprilaire EV130 8100

33. Installation Comparison uAny case orientation u uSimplifies ducting uIntegral mounting flanges uHanging straps available at no additional cost

34. Weather Hoods

35. EV130 Ceiling Mounted

36. Venmar Constructo 1.5

40. Air Flow balancing is not a problem for RenewAire!  Condensation and frosting does not occur which restricts air flow in the exhaust air stream.  Strong blowers mean trouble-free installations.  Differences in duct pressure have little effect on airflow rates.
