Jot Energy also provide
airtightness testing and thermal imaging services, and having a single point of contact for all things associated with getting the performance of the house optimised was extremely attractive.

In 2006, the International Residential Code tightened up the language to require walls to be sealed, and as of 2009, the IECC requires
airtightness testing.
Higher energy standards during building and
airtightness testing are two key factors in achieving better homes across Europe.

Airtightness testing: Air Seal Ltd..
Specially constructed airtight ply boxes were installed to receive the new windows, and also allow for preliminary
airtightness testing to more accurately reveal air leakages elsewhere in the house
A building's
airtightness test result isn't just an indicator of its energy efficiency — it's an unambiguous indicator of build quality.
The first
airtightness test has taken place at phase three of the Silken Park development at Citywest, which is set to be Ireland's largest residential passive house scheme.
The strategy worked, and the fabric of the new houses passed
the airtightness test comfortably at 0.4 air changes per hour at 50 Pascals.
The final
airtightness test recorded a result of 0.77 ACH at 50 Pascals — well within the Enerphit threshold.
Putting aside concerns about some of the assumptions in Deap — for instance assuming air permeability of homes without
airtightness test results, when the evidence indicates that homes built in the second half of the 20th century may be much leakier than pre-war homes — HPAI's SEAI liaison officer John O'Shaughnessy said: «Deap is the preferred tool of the department and has proven to work on a lot of social and fuel poor energy upgrades in the past.»
The building scored an impressive
airtightness test result of 0.5 air changes per hour at 50 Pascals — a score that not only blitzes the requirement for Enerphit (the passive house standard for retrofit), but comfortably beats the new build passive house target of 0.6 ACH too.
The worst
airtightness test result on completion was 0.812 ACH at 50 Pa..
This meant Cooper Insulation could test for obvious leakage points as they worked, and thereby ensure the eventual obligatory
airtightness tests wouldn't throw up any nasty surprises, thus avoiding the need for difficult and costly remedial work.
Ultimately all of the forethought and planning proved its worth, and the house got 0.3 air changes per hour on its first
airtightness test, and 0.4 on its final test.
Not exact matches
In terms of
Airtightness, a maximum of 0.6 air changes per hour at 50 Pascals pressure (ACH50), as verified with an onsite pressure
test (in both pressurized and depressurized states).
After the air barrier is complete, but before the drywall is up, we will conduct another blower door
test to make sure that the building's
airtightness is below the Passive House retrofit standard of 1 ACH50.
Test used to determine a home's
airtightness: a powerful fan is mounted in an exterior door opening and used to pressurize or depressurize the house.
Airtightness of buildings, for example, has increased because many building codes now require
testing.
Though the building wasn't designed as a passive house, careful attention to
airtightness using Ampack's range of tapes and membranes, with particular attention paid to key junctions such as windows, chased walls and a counterbattened service void in ceilings, leading to an impressive pressure
test result of 0.48 ACH.
Every building must pass a blower - door
test demonstrating exceptional
airtightness.
Photo: Charlie HoxieFortunately a building's
airtightness can be readily measured, at minimal cost, with a blower door
test.
The detached masonry build had beaten the 0.6 ACH passive house
airtightness target during a blower door
test a few days earlier.
is located at ceiling rather than roof level,
airtightness can be
tested at the factory.
