- Richard McCarthy from Ballyfermot ETB demonstrates methods to find air leakages when checking for airtightness in a building. Recorded during delivery of the Foundation Energy Skills course 2016. Low energy building, construction training, airtight layer, airtight membrane, air leaks, blower door test, air changes per hour, airtight tapes, airtightness, depressurise building, windows, fixing leaks.
Great video. I suggest when feeling for leaks, dampen your hands with water. Makes them more sensitive to temperature change
Vodka works great too.
@@ChuckFrenchNH 😂😆 that's a great response!
I happen to live in a passive house since 21 years now, pay 124 EUR per YEAR for the heating of 90 sq.m. and am happy to FINALLY see that the topic gets attention. Very good presentation!
I am in the process of tracing these sorts of leaks in my 3 bedroom terraced house, and it is amazing how much difference it has made, just sealing some very tiny leaks. Many thanks for this clip, which I really enjoyed watching. Certainly given me one or two ideas to play around with.
I'm in the same boat, just found that 2 windows are fitted so "great"(FENSA certified) that I can poke 8mm stick trough!!! and my main doors(£3000) will never seal properly. Again British Satandard compliant. Or as I call them BullShit standard.... Sorry had to vent somewhere.
Thanks so much! Best video explaining how to handle those elusive leaks! 💯
Every builder, architect and person building new home needs to attend classes like this.
They would better appreciate the need to air sealing and blower door testing.
Excellent demo with the balloons. It should be used to promote Passive Haus.
Nice presentation!
Hi, are the holes in membrane made by the staples holding it to the studwork not a source of air leakage?
A more comfortable home. A more energy efficient home.
Saving energy saves money on utilities.
From Port Alberni in the Heart of Vancouver Island BC Canada passive house build czcams.com/users/seumas2videos
To date 37 detailed videos with material used
Port
Alberni's first Passive house (Passivhause) build in the heart of
Vancouver Island British Columbia Canada.
Passive
House(Passivehaus) is considered to be the most rigorous
voluntary energy-based standard in design and construction industry
today.
Passive
house buildings consume up to 90 percent less heating and cooling
energy than conventional building.
The
use of Passive House design software was used to gain the specs
required to meet the performance standard for this location.
House
was constructed well above the current standards as outlined in
the B.C. Building Code.
Footings
were widen to 36 inches(914 mm) due to low bearing soil conditions
and additional rebar reinforcement added.
30
inch high (762 mm) high reinforced walls . Course sand placed inside
foundation walls and mechanically compacted.
Three
layers of four inch *102 mm) thick Expanded
polystyrene foam sheets with all joints staggered and tape were
placed on top of compacted sand.
The
three layers of foam have insulation value of approximately R 50.
A
20 mil layer of poly was placed over the E.P.S. sheets and taped and
sealed.
Four
inches(102 mm) of 30 m.p.a fiber reinforced concrete was placed to
form a slab over the foam based.
Slab
is isolated from concrete stem wall with four inches (102 mm) of
E.P.S. to prevent thermal loss.
All
cold water lines are buried in the sand to keep them cool, hot water
lines have been placed in the center layer of foam insulation to
minimize heat loss.
Wall
plates compress to heavy beads of acoustic sealant between layers of
vapor barrier to prevent air movement.
The
walls are double stud configuration set at 24 inches (610 mm) on
centre and plates are spaced in a manner that yield a 20 inch (508
mm) thick wall. 1/2 inch (12 mm) standard plywood sheathing with
Mento 1000 a three layer airtight vapor open house wrap( far superior
to common house wraps) with 1/2 inch(12 mm) pressured treated plywood
rain screen battens form the exterior surface.
Intello
smart vapour barrier was installed one third in from the inside wall
to prevent condensation in this climate.
Triple
pane argon filled windows meeting passive house standards from
Euroline were placed mid wall to reduce wind wash heat loss.
All window openings have been splayed at 45 degrees to give a full
wide angle view.
Almost
all the wiring and plumbing was kept inside of the vapor barrier
envelope to minimize air leakage.
Passive
house standard requires air leakage not to exceed .6 Air
changes per hour at 50 pascal.
Zehnder
comfoair 200 HRV has been installed with a 1000 watt air preheater
.(92 percent heat recovery rate)
House
has been pre- plumbed for a heat pump water heater reducing
domestic water heating cost significantly.
Garage
has been pre-wired for 40 amp/240 volt electric car charging
station.
House
to be equipped with heat pump condensing dryer which
requires no external venting,only a water waste line. George K

Everyone should get this done at home
Yes def for energy savings...but if you don't make sure your house also has proper ventilation (fresh air) you are sealing all the VOC's (volatile organic compounds) up inside. Also for fresh oxygen if you have appliances that burn gas.
Not everyone, every house needs enough air changes per hour to keep moisture and CO2 levels down. Every house with MVHR system installed needs to be as airtight as possible.
Just started watching, but he's a great instructor. Even I understood.
(Plus: I'll be more careful of balloons I buy for kids.
Too old to keep blowing up same balloons ;~)
Air changes per hour
wat even is this it looks like it was made with moviemaker
