Futureproof: Site Visit to Wiltshire Passivhaus-standard new build

4/3/2019

0 Comments

 
On 15th March we'll be collaborating again with The Green Register opening up our site at Eastrip Lane, Colerne for a Futureproof site visit and talk about this contemporary three-bedroomed timber frame house built to Passivhaus standards.

The topics discussed in this tour and talk - materials used, MVHR, airtightness and methods of construction - are just as relevant to retrofit as new build projects.

The building is timber frame constructed on site from 360mm timber I-beams and wrapped in 100mm Pavatex woodfibre boards. The external faces will be either render or geometric cement sheet panels, whilst the roof is anthracite corrugated cement sheet. Windows are from Internorm (Passivhaus certified).  All walls and roof will be insulated with Warmcel 500 Cellulose insulation.

The building is still under construction and so during the visit, it will be possible to see all aspects of the building fabric: air tightness layers, MVHR ducting, timber frame and Pavatex wood fibre.

Places are limited. Visit The Green Register website for full details and to book online.

Futureproof: Training for Builders 1 - Introduction to Sustainable Construction

4/3/2019

0 Comments

 
There was a good turn out in Bristol on February 27th for the Futureproof training  - a collaborative event between ourselves and The Green Register.

The afternoon was a good mix of talks and practical demonstrations, with some very positive feedback at the end.  Attendees were mostly builders - our target audience.

Richard and Malcolm gave a short talk about sustainable building and It was great to see the Earthwise project again and to see them achieve an impressive air tightness result - well done guys!

Here's to more regular training events aimed at builders - green builders!

No Gas? No problem! Greenheart respond to Committee On Climate Change UK Housing report

Urgent Government intervention is required and the construction industry must remove its head from the sand - our to Committee On Climate Change UK Housing report
 
For those of us promoting sustainable building for decades, the recently published Committee On Climate Change (CCC) report UK Housing: Fit For The Future? says nothing new.  The report is hardly as radical as some suggest - it describes what we at Greenheart Sustainable Construction are doing right now, and have done for nearly two decades.
 
There is clear demand for this type of building approach, and we suggest it is time the Government and the industry moved into the 21st century and took this seriously.
 
Greenheart Sustainable Construction have been building gas-free, low-energy, timber frame, super-insulated homes for some time now.  Since 2000, we have built above and beyond the current regulations, researching and implementing new and progressive construction methods and technologies. The knowledge and products are available - Air Source Heat Pumps (ASHP) and Solar PV to induction hobs and LED lighting - but remains a small niche part of the wider industry, which is sadly resistant to change.
 
Government funding and intervention is urgently required.  Without this, the industry will continue to build to a level that struggles to meet current regulations - let alone building for a sustainable future.  We suggest:
​
  1. Setting standards for building regs with clear steps over the next few years.
  2. Effective building regulations enforcement for all housing
  3. Setting industry minimum qualifications and experience
  4. Funding proper training and enforce CPD type ongoing training.
  5. Grants for PV and ASHP to help boost the take up of these technologies
  6. Better promotion of timber frame construction – the UK lag miles behind Europe and the US on this.
 
The building sector itself must also take greater responsibility for the performance gap.  A more regulated, professional, educated workforce is desperately needed. We at Greenheart, along with pioneering training organisation The Green Register, are currently promoting such education for construction professionals.
 
An enormous cultural shift is required but without this the words in the CCC report will come to nothing. If we all play our part we can construct a greener future.

Futureproof Training flyer
We are delighted to be teaming up with The Green Register once again to offer an Introduction to Sustainable Construction - the first of a series of half-day Futureproof training events, which are run 'By Builders For Builders'.
​
We'll be returning for a second look at the new build housing scheme for Somewhere Housing Association in Bedminster, Bristol.  Alongside fellow local contractors Earthwise, we will talk about how our method of working results in high quality, sustainable buildings, satisfied clients and proud builders

Ian Mawditt of FourWalls will be testing the building with a blower door test and there will be a demonstration showing how to use a thermal imaging camera to identify cold bridges.

Tom Heywood from The Green Building Store will be giving a Q&A session on the MVHR system that Earthwise have installed.
