They state the assessments are to be done between june and september without any course being available yet (i assume they are talking about 2008)....

Take an analogy with "external wall to achive 0.25 Wm2 K U value" We have a methodology to to "play" with different wall construction types and can engineer different material layers and thickness to acheive precisely 0.25 . We can then adjust material thickness to answer a query like- "what if we want to improve the wall to 0.22 Wm2 K " Is there a method to calculate air tightness levels like this ?

A lot of good guidance . thanks for that But is there a way to "engineer" ait tightness like with u values - it appears not Designers set the target and trust to specialists to achieve those targets . I know that the UK retails giants are "big" on this and sometimes a lot of "snag / test / snag again / test again etc " occurs close to completion of those projects . This text is pasted from the link ( my underlining ) "The performance specification allows appropriate targets to be set for the project, along with a description of how the process is to be conducted, in terms of scheduling, audits and testing, and potentially remedial works. Given the increasing use of specialist subcontractors, particularly in larger projects, it is also critical that the performance specification sets out both the responsibility for, and constructive guidance regarding the co-ordination of trades with respect to the final air permeability of the completed envelope"
topcatcbr wrote: » As far as i know you are right, their is no way of engineering air tightness values as alot of the performance is dependant on workmanship, however a build method ( Insulated Profile metal cladding vs Traditional build,etc) and detail specification can give expected results and by specifying a performance it indicates the quality of workmanship and possibly build method required to meet this specified target. It is not exact and if the building does not meet this target their may be remedial measures which can be imposed. I hope my reply is not too vague but it is a hard question to answer in a forum like this. I get the impression you are reasonably familiar with this anyway. We will just have to muddle through for now.
