Four Oaks Passivhaus Project in the news

The Passivhaus Trust website featured the Four Oaks Passivhaus project in it's news section.

We are now at Building Regulations submission stage and planning to go to tender in March.  Lots more to be done on detailing the timber frame construction, glazing and heating, hot water and ventilation in coming weeks. 

For more information see projects.







Four Oaks Passivhaus Submitted for Planning


We have been assisting a private client and local architect MJW Architects develop designs for a new build Passivhaus in Nailsea, North Somerset.  The building is a detached two storey replacement house.  We have advised on wide ranging aspects of the design including location on site, orientation, layout, form, fenestration, construction and services. The building has been modelled in PHPP and the results used to advise on design options, particularly shading of the large areas of south facing windows, which has been achieved with sliding shutter doors and brise soleil.

Importantly, with the imminent winding down of the Code for Sustainable Homes we have asked the planning department at North Somerset Council to consider Passivhaus as an alternative to the current requirement of Code level 3 for all dwellings.  Initial responses suggest that this is viewed positively.

We will publish the outcome and further project developments when the planning application is determined. 



Expert Energy Advice for New Winery Building

We are providing advice on constriuction detailing and energy systems for a new straw bale winery near Monmouth.

We have evaluated building fabric designs using IES VE software and decided to follow a Passivhaus based approach, with high levels of insulation, thermal bridge free construction, airtightness and MVHR.  We are also looking at combining ground source heating with MVHR to achieve the cool, stable temperatures required in the building.


New Services Offered in 2013

We are now able to provide Code for Sustainable Homes, BREEAM and Non-Domestic Energy Assessments (EPCs). This enables us to broaden our core business of providing sound energy and sustainability advice to non-domestic projects and those which require Code and BREEAM.  We are currenly providing advice to Ancre Hill Vineyard on the energy aspects of it's new winery.
