Comment by Mark Siddall on November 19, 2010 at 15:54: Joseph,
I would propose that Passivhaus is not a "technique", rather it is a quality assurance standard for energy efficient buildings. This is to my mind an important distinction.
The correct design techniques need to be in place in order to allow construction to achieve the requisite airtightness i.e. it it not for the contractor to do alone. The exact solution will be dependent upon the construction technology being used - currently i have not found any British guidance publications that deal with airtightness in an appropriate manner. Though some products by manufacturers such as Pro-Clima and Siga are increasingly available. HTH.

Comment by joseph knight on November 19, 2010 at 13:39: Hi, i am carrying out research on the Passivhaus technique, and i intend to publish my findings on the site http://www.energy-measures.com. If anyone has any information on the practical issues in achieving passivhaus standard this would be appreciated, particularly with regard to minimising air leakage. Thanks

Comment by John Stobbs on November 18, 2010 at 11:16: Hi Sitaram
Good luck with this course - keep in touch with us on your findings as some of our clients are interested also.

Nice to see you in the group

Comment by Sitaram Mudumbi on November 18, 2010 at 10:59: Hello All, 'Just joined the network. I will be taking eco-refurbishers' course with the Green Register in December.
Has anyone already attended this course and has this helped your business into a new sector? If not, I will drop comments after attending FYI. Best of luck in what's left of 2010 and here's hoping 2011 isn't as bad as many fear!

Comment by Damien Mulgrew on November 12, 2010 at 10:53: Hello people,

Im currently on my placement but I want to consider my dissertation ideas now so that im a step ahead come september next year... and could potentially have the majority of my draft written up. As I am interested in passivhaus and sustainability in general, are there any aspects which you consider may have flaws in it or require further research to justify its use in the current climate?
