You mention 'energy consultant' and 'qualified passivhaus consultant'. What exactly do those terms mean/refer to in your context?]]> http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17213&Focus=292017#Comment_292017 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17213&Focus=292017#Comment_292017 Wed, 29 Sep 2021 17:18:08 +0100 gravelld http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17213&Focus=292021#Comment_292021 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17213&Focus=292021#Comment_292021 Wed, 29 Sep 2021 18:57:03 +0100 Nick Parsons
Assuming you have good links with contractors who did what you asked them to do you are in a strong position to do baseline surveys for householders, make recommendations and then actually have someone who could do the work. The issue I have on a regular basis is not being able to find contractors. The experience you will have re air-tightness and dealing with thermal bridging will be invaluable.]]> http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17213&Focus=292033#Comment_292033 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17213&Focus=292033#Comment_292033 Wed, 29 Sep 2021 23:23:29 +0100 bogal2 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17213&Focus=292036#Comment_292036 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17213&Focus=292036#Comment_292036 Thu, 30 Sep 2021 10:37:13 +0100 revor http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17213&Focus=292065#Comment_292065 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17213&Focus=292065#Comment_292065 Thu, 30 Sep 2021 22:19:59 +0100 Newbuild http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17213&Focus=299738#Comment_299738 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17213&Focus=299738#Comment_299738 Thu, 19 Jan 2023 11:40:47 +0000 bogal2 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17213&Focus=299810#Comment_299810 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17213&Focus=299810#Comment_299810 Sun, 22 Jan 2023 18:13:13 +0000 cjard
G3 cert for unvented HW more like.. Unless you plan on only installing open vented thermal stores?]]> http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17213&Focus=299817#Comment_299817 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17213&Focus=299817#Comment_299817 Mon, 23 Jan 2023 09:51:12 +0000 Nick Parsons
PAS 2035 sets out a sensible framework for project control and risk minimisation. That has to be good, especially as the PAS 2035 standard was (is) a response to well-documented failings in the past. However, since individuals and organisations have achieved good results in the past without the disasters referred to then it probably is not the only viable model. Ask all the 'Superhomers' (superhomes.org.uk) or a number of initiators of well-publicised schemes. Read Passive House Plus for really successful projects, etc. etc....

If you did the Carbonlite Retrofit course you'd have the learning (and you probably have all the site co-ordination experience anyway) and then (or already, now) you could perhaps be a retrofit co-ordinator, rather than a Retrofit Co-ordinator. I have helped clients co-ordinate their retrofits for some years but always on privately-funded projects rather than Public- (or Energy Co. -) funded schemes.

PPR's Home Retrofit Planner tool is very good - I have used it on a number of occasions. It is SAP-based but they have painstakingly ironed out a lot of the 'wrinkles' in SAP.

I do 'elemental' surveys, which simply look at estimated existing U values, calculated 'after works' U values and consider thermal bridging and air-tightness. I do not attempt to estimate costs of works or post-works running costs. Some people like this approach and some don't, and the 'models' exist for both.

Good luck whatever you choose. I think even if you go down the HP route your more general retrofit (and PH NB) experience will be invaluable to your clients, so you may end up being a 'HP Contractor+++' (in terms of added value.]]> http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17213&Focus=299864#Comment_299864 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17213&Focus=299864#Comment_299864 Tue, 24 Jan 2023 22:58:51 +0000 bogal2
