March 2015 Progress Update

Progress update on the Green Build Hub, M&E installation started onsite, Rationel timber framed triple glazed windows delivered to site, students and training taking place in the hub already and the revealing of the large space.

Its been a very busy month for our contractors and progress is moving quickly, the walls are now lined with Fermacell board and have been dry lined ready for painting and our surface fixed M&E installation. The internal scaffolding has been taking down to free up space to work in the main room and the external cedar cladding is half way complete.

 Roof Stubs installed and Resitrix roof covering complete 

The new office for CSBT taking shape

CSBT attend Hoare Lea Sustainability Workshop

Nicole from CSBT had a very interesting visit to the offices of Hoare Lea in Plymouth on Thursday 12th February to attend a Sustainability Workshop. Hoare Lea are consulting engineers specialising in Mechanical and Electrical areas of construction, and are working with CSBT on the Green Build Hub.

The workshop was presented by Ashley Bateson, Partner at the firm and responsible for their sustainability division.

Issues covered included the change in Part L of the Building Regulations in the UK (which refers to the conservation of heat and power in a building), BREEAM 2014 updates, carbon offsetting of construction projects and the ‘soft landings’ approach to handover of buildings on completion.

The 2013 updates to Part L of the building regs were implemented in 2014 and aim to reduce CO2 emissions in residential properties by 6% and 9% in commercial on previous standards

Fuel emissions factors have been changed – see slide below


BREAM 2014 updates: some headlines for new construction projects:

  • Credits for a building’s adaptability to climate change
  • Sustainable procurement – responsible sourcing of materials
  • Sustainability Champion
  • Buildings over 1,000 m² required to have an appropriate energy monitoring and management system and smaller ones to have suitable meter outputs.
  • Passive design analysis added
  • Designing for durability and resilience now an added factor

A BREEAM Excellent rating in 2011 would have to score 75.28% but in 2014 this was reduced to 70.87%.

For rural areas there has been a relaxing of the cycle storage requirements – by 50% if 10 miles from an urban area (if 20 miles, reduced by 70% and 30 miles, reduced by 90%).

There is also now less emphasis on low carbon technologies to score points and more emphasis on low carbon design.

February 2015 Progress Update

Progress update on the Green Build Hub, Scaffolding finished, Roof watertight, Wall sensors installed and a site visit from Nick Boles MP, its all go!

Insulation has arrived on-site ready for installation to help the Green Build Hub reach its U-values and BREEAM credits.

We are launching our fit-out competition for the Green Build Hub very soon.

We are still open to collaborators and supporters to join us here at CSBT please let us know if you would like to be involved.


Thermal Imaging & Air-tightness Presentation and Demonstration

Advantages of using Thermal imaging in association with air-tightness

Rachel Simpkins from South West Air Energy & director of Sustain Cornwall will be sharing the advantages of thermal imaging assessments and air-tightness of buildings.

Jason Jarvis a chartered architect, board trustee of CSBT & director of Sustain Cornwall has deigned and built ‘Hillstone’. He scooped Highly Commended in the sustainability at the Natural Stone Awards 2014, and will opening up his home for this event. Jason will be presenting his design and actual working challenges of achieving air-tightness and thermal performance.


A: Air-tightness theory versus actual
B: Benefits and use of thermal imaging
C: Live demonstration – Hillstone will be the test property using air test equipment
& thermal imaging camera

Timber Frame Workshop Training Opportunities

We have had 4 full time Wood Occupations Level 1 students from Cornwall College St Austell, on a one day a week, 4 week, work experience placement here at CSBT. Modern Methods of Construction (MMC) are a growing option for the construction industry, moving away from traditional building methods. It is essential that here at CSBT we are catering for changes in the industry and enable companies and individuals opportunities to up-skill in order to help businesses to remain viable and flexible.

Below is a video showcasing the on-site construction of the timber frame element of the Green Build Hub and how at CSBT we are engaging with local students offering hands on work experience. The students have really enjoyed the experience and we hope it aids them to secure apprenticeships next year to progress to NVQ level 2 and 3.

Air Tightness and Thermal Imaging CPD

In January we are planning to host a CPD event on Air Tightness and Thermal Imaging, please watch this space for further details

The outline plan is to have a brief presentation on why airtightness is important, and then introduce methods of identifying leakage including thermal imaging and its benefits in identifying leakage areas along with some photograph/presentation examples.

There will be a brief demonstration in a test property using the air test equipment and the thermal imaging camera at the end of the session. Details will also be provided on what other situations thermal imaging can be useful for clients.

The event will be run by Rachel Simpkins of South West Air Energy, keep an eye out for event updates
