Part L

In the first of this series of posts, I set the background to the Part L 2010 consultation. In this post I am going to look at the issues which were raised at the recent Sponge/CIBSE consultation event , which I attended on 20 August. Hywel Davies presented 7 issues which were of concern to […]

by mel starrs on September 7, 2009

in Part L

So after a fun (?) summer of consultations, the final date for submission for the Part L and F consultation will soon be upon us: 17th September. The consultation came out on 18 June, but with a massive 800 odd pages to wade through it has taken most of the summer to digest. This series […]

Electric heating – the future?

by mel starrs on October 23, 2008

in Part L

Well, I never thought I’d write that as a blog title! I’m not a fan of electric heating and haven’t been since before I did some investigation into Part L back in 2002. However, as I was browsing through my copy of h&v news this week I came across an article by Kelly Butler of […]

Part L consultation and multifoils

by mel starrs on June 24, 2008

in Part L

I’ve read through the (non-technical) consultation which is out for Part L – comments to be back by 9 September. The only item which piqued my interest was the clarification regarding multifoils. 3.1 BR 443 “Conventions for U-value calculations” sets out test methods and calculation procedures for determining the thermal performance of building elements that […]

Today I have been testing out Stroma’s new FREE software for Code for Sustainable Homes. It’s a spreadsheet tool which allows you to see the consequences of adding or deducting points from CSH. Something you could do yourself with an hour or two and editgrid or excel, but it’s nice to have a slick professional […]

Who needs hindsight?

by mel starrs on May 23, 2008

in Part L

I was just perusing through the archives of BSJ looking for something else entirely, when I came across this debate from 2000 on the then proposed Part L. I found this paragraph to be particularly enlightening: The clauses covering overheating criteria for naturally ventilated buildings puzzled more than one delegate. Oscar Faber’s Ant Wilson queried […]

Electric heating under fire (again)

by mel starrs on February 7, 2008

in Part L

Well, I hate to say I told you so but we’ve been here before. Back in November 2002, I wrote an article for BSJ* pointing out the iniquities of the factor used for electricity in the old Part L.  Seems Code for Sustainable Homes still has a flawed factor included and a similar loophole to […]

HIPs delayed till 1 August

by mel starrs on June 22, 2007

in Part L

I’m a bit very late in commenting on this, but the inevitable delay to HIPs has been announced.  The government’s phased roll requires HIPs for properties with four or more bedrooms from 1 August, followed by three-bed homes once 2,000 energy assessors have qualified, and all homes when 3,000 have qualified. On 22 May NHER […]

in Part L

I’m back, from outer Mongolia (literally).  Whilst I’ve been incommunicado for the past few weeks, I gather there have been interesting developments with HIPS.  I’m off to catch up on all the industry gossip – more comment to follow no doubt.  In the meantime, Rokia Raslan at Bartlett has a short academic survey on Part […]

iSBEM version 2.0

by mel starrs on May 23, 2007

in Part L

Firstly, is anyone still struggling along with the Access version of iSBEM?  Or is everyone using either Hevacomp, IES or TAS? Let me know in the comments. If you haven’t had a tinker with iSBEM yet, there is a new version out now, although some problems have been identified running it on Acess 2000. I […]
