2 HOMEOWNERS COMPLAIN UNEVEN HEATING/COOLING

3 HOMEOWNERS COMPLAIN UNEVEN HEATING/COOLING OFTEN ACCOMPANIED WITH WET ATTICS WHICH LEADS TO MOLD

4 HOMEOWNERS COMPLAIN UNEVEN HEATING/COOLING OFTEN ACCOMPANIED WITH ICE DAMS WITH ROOF LEAKS AND GUTTER REPAIRS

5 HOMEOWNERS COMPLAIN UNEVEN HEATING/COOLING OFTEN ACCOMPANIED WITH WINDOW ROT FROM CONDENSATION

6 SOLUTIONS GET GREAT SAVINGS FROM ENERGY COST REDUCTION AIR SEALING MEASURES BEST RETURN ON INVESTMENT! ALWAYS SEAL CEILING 1 ST IT HAS THE MOST HOLES GREATEST OPPORTUNITIES

7 MOST LIKELY TO IMPROVE COMFORT COMPLETE AIR SEALING ENVELOPE BECAUSE Premier Building Scientist, JOSEPH LSTIBUREK When answering question: WHY BUILD A TIGHT HOUSE? Before you can control air you must enclose air. Over ventilating during cold weather leads to comfort problems. Builder s Guide To Cold Climates Chapter

8 MOST LIKELY TO IMPROVE COMFORT COMPLETE AIR SEALING ENVELOPE BECAUSE WINTER TIME STACK EFFECT BIGGEST AIR LEAK DRIVER RETARD STACK EFFECT - CAP CEILING WHEN AIR SEALING COMPLETE IMMEDIATELY RESOLVES VIRTUALLY ALL UNEVEN HEATING/COOLING CONCERNS

9 WHEN A TIGHT HOUSE FEELS WARM/COZY? NO NEED TO UPGRADE EXISTING HVAC DESIGN? AIR SEALING WORK COST-EFFECTIVE WHEN COMPARED WITH HVAC WORK REPAIR/REPLACE UNDESIGNED OR DESIGNED DUCTWORK ZONE SPACE CONDITIONING

10 DOWNSIDE TO HVAC 1 ST UNLIKELY HVAC REDESIGN WILL WORK WELL CREATE A NEW UNSEEN ISSUE MAKE EXISTING ISSUE WORSE

11 A NOTE ABOUT CASE STUDIES EMPHASIZE BEST AIR SEALING PRACTICES! 1,000s OF YEARS OF FIELD EXPERIENCE IN THIS AUDIENCE NOT FINGER POINTING - SEE ISSUES AS NUGETS OF KNOWLEDGE

12 A NOTE ABOUT CASE STUDIES THIS SHOULD GO WITHOUT SAYING. IF YOU RECOGNIZE A CASE, PLEASE KEEP IT TO YOURSELF.

13 I TRUST INSTALLERS WANT TO SOLVE COMFORT ISSUES! Verify SUCCESSFUL Efforts with PERFORMANCE TEST STANDARDS KNOW HOLES SEALED BETWEEN LIVING SPACE AND UNCONDITIONED ATTICS! OUR DESIGNED SOLUTIONS ARE DATA DRIVEN WE GENERATE DATA AND ANALYZE IT AGAINST LONG STANDING TESTING STANDARDS

14 TOPICS FOR DISCUSSION HOW CAN WE KNOW HOLES ARE AIR SEALED? SPS 322 WISCONSIN ADMINISTRATIVE CODE STANDARDS FOUND THERE OTHER STANDARDS USEFUL TOO! HOW MUCH TIGHTER SOLVES COMFORT? DEFINE AIR BARRIER

15 TOPICS FOR DISCUSSION CASE STUDIES PROVIDE INSIGHT? TWO CASES STUDIES INITIAL CONCERN WET ATTIC SECONDARY CONCERN UNEVEN HEATED/COOLED SPACES SEAL CEILING 1 ST VIRTUALLY ALL CEILINGS NEED IT!!! ONCE SEALED, AIR CONTAINED COMFORT RETURNS

19 DEFINE AIR BARRIER: SYSTEMS OF MATERIALS DESIGNED AND ASSEMBLED TO CONTROL AIRFLOW THROUGH THE BUILDING ENVELOPE SEPARATES INDOOR AND OUTDOOR AIR CONTINUOUS, SEALS THE ENTIRE ENVELOPE! SINGLE OR COMBINATION OF MATERIALS STOPS CONDITIONED AND WATER VAPOR LADEN AIR FROM VAGRANTLY LEAKING!

20 CAUSE OF MOLDY ATTICS MUST CONTROL SOURCES OF MOISTURE CONTROLLING VAPOR LEAKAGE TRUMPS ATTIC VENTILATION NEVER JUST ADD VENTS AS SOLUTION! IT LL EITHER MAKE AN EXISTING ISSUE WORSE CREATE A CONDITION WHERE IT DIDN T EXIST COLD ATTIC AIR CAN T HOLD THE AMOUNT OF VAPOR FOUND IN LEAKING LIVING SPACE AIR! REALLY? PROVE IT!

22 HOW MUCH VAPOR CAN AIR HOLD?

23 RH LOWERS WHEN AIR WARMS BEAKERS AIR S CAPACITY TO HOLD VAPOR EACH BEAKER SIZE DOUBLES RH DROPS BY HALF EACH 20F WARMER TEMP. 50% 25% 12.5%

24 RH RAISES WHEN AIR COOLS VAPOR ADDED TO INDOOR AIR BATHE BREATHE COOK AND LAUNDER RH RAISES UNTIL SATURATED LEAKING AIR COOLS IN ATTIC AND ROOF DECK DAMP EXCESS VAPOR CONDENSES

25 WHICH WATER VAPOR TRANSPORT MECHANISM IS THE BIGGER CONCERN? DIFFUSION OR AIR LEAKAGE Builder s Guide to Cold Climates 2012 By Joseph Lstiburek

26 Builder s Guide to Cold Climates 2012 By Joseph Lstiburek

27 SOLUTIONS FOR MOLDY ATTICS CONTROL SOURCES OF WATER VAPOR ELIMINATE ALL WE CAN CONTROL WHAT WE CAN T ELIMINATE KEEP INDOOR AIR FROM LEAKING AIR SEAL CEILING 1 ST INSTALLER S SUCCESSFUL EFFORTS VERIFIED ZONE TESTING DATA ANALYSIS AIR SEALING IS SUCCESSFUL WHEN DRYING OUTPACES WETTING
