NZEB and Part L 2019

Building regulations upcoming changes to Part L, taking effect on the 1st November 2019 seems to be raising a few eyebrows. For new dwelling’s we are now looking at the NZEB standard. There has been some tweaking of the U-values and ventilation rates but in the main still close to the 2017 standard. On the [...]

Septic tank pump ‘Burning out’

Over the years I have encountered many instances where the discharge pump would burn out, every two years or so, sometimes annually. Really a pump should last much longer (some for 10 years or more). So why do they burn out? There are really, only two reasons for this. 1. The pump is not strong [...]

Attaining standards

Following up on a fellow techie’s recent BRegsForum blog post, lamenting in part the lost opportunity to bring improvement & greater control as promised under SI9. I’m not sure if the ‘opt out option’ results in a lost opportunity to improve the construction sector. I feel the aims of SI9 can only actually be achieved [...]

Building Regulations S.I. 365

The September 1st changes to the Building Regulations or more accurately the Building Control Regulations have been met by and large with great approval, and the news in slowly spreading. For the domestic one-off market March 2014 (S.I. 9) was a crusher as it meant extra costs, piles of paper work and piles of stress? [...]

Not speaking about costs of getting provisional & final BER's, but more importantly the build cost of what’s proposed in the Provisional BER. The standard approach to insulate well is good advice. But the there is a point where adding more insulation is not cost effective. If Passive standard (again good advice) is not your [...]

Ventilation

We all know the importance of ventilation, or at least we should. Healthy living means healthy accommodation and includes ventilation. I know you might feel there is a contradiction here, with building regulations requiring airtight houses while at the same time ordering holes in the walls. But the point of having an airtight house is [...]

Septic tanks – Part H compliance

For rural projects with stand-alone effluent treatment system, the design and detailing of the system should be carried out at ‘Design’ stage in order to demonstrate compliance with part H of the building regulations. For varies reasons it may become problematic for projects if the design & detailing are not address at this stage. Crucial [...]

What do the new building regulations mean for me?

In the past people would often have taken the drawings used for the planning application, and used them for building (in truth this has often lead the problems). But with the new regulations clients now have to submit varies detailed drawings, calculations and certificates etc. when lodging the commencement notice to the local authority (LA). [...]

Building air tightness

I'm coming across lots of problems and mistakes on site, along with some unnecessarily detailing. Air tightness is something you would think about when putting together builders drawings; especially if you are dry-lining the property. Key area's to get right are: window junctions ceiling junctions floor junctions We got [...]
