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.







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.
