Meeting Stephen Williams MP on Housing Standards

I met @SWilliamsMP - Minister for Communitities and Local Govt (and my local MP) today to discuss housing standards.  He confirmed that local authorities would continue to be able to set their own building energy standards until Zero Carbon Housing was introduced in 2016.  He did recognise that Zero Carbon Housing was not really zero carbon but seemed confident that the Zero Carbon Hub had everything in hand eg quality on site, performance gap etc.  I'd have liked to have talked about linear thermal bridging and psi values, as I see this as an ongoing problem which is currently being fudged and will continue to be until SAP takes measurements externally. I really don't think he would have understood though so I didn't bother.  

I asked him for support for Bristol Green Capital and he sugested that Bristol could aim to meet the 2016 Building Regulations in advance of them being introduced.  Not exactly innovative or imaginative!

Ancre Hill Winery - new straw bale winery building going up 


Ancre Hill Estates is an organic winery in Monmouth specialising in quality sparkling wines made in the champenooise style.

We have been helping them with energy aspects of the design of their new winery building where wine will be made, aged and stored.  

The new building is a steel portal frame farm building with straw bale walls and sedum roof. Attention has been paid within the design to making the building airtight and thermal bridge free.

The building has specific temperature requirements in different rooms and at different times of year.  

To  minimse energy use the building will have no heating or cooling systems.  

Ventilation is required to remove CO2 that is generated by the fermentation process. We have been working with Green Building Store to develop a control system for the Paul Novus 450 Mechanical Ventilation with Heat Recovery (MVHR) unit, which is able to manage the CO2, maintain humidity levels and provide adequate night cooling in summer.  

The building is being built by G Adams Construction with training and supervision in straw bale construction from the Doret Centre for Rural Skills.

An air test was undertaken by John from Building Analysis and Testing yesterday at 101 High Kingsdown.  This is a 1970s refurbishment.  We were pleased with the air permeability of 2.1m3/m2/hr @50pa which beat the target of 3.  The main areas of leakage were between the ground and first floors and partition walls where we knew we had to make compromises due to access.  The result is compatible with the installed Paul Novus MVHR from the Green Building Store.

New projects gallery

We have restructured the website a little to make it easier to view projects at a glance.  The projects tab on the right now links to a gallery page which shows pictures and descriptions of some key projects.  We will keep adding more.
