Business Description

Bryn Elltyd Eco Guest House is one of the leading, award winning, eco-friendly B&Bs in the UK, and one of only 4  B&Bs in Wales to achieve the Gold Green Tourism award. Nestling at the foot of the Moelwyn mountain range and alongside a lake, Bryn Elltyd B&B is ideal for exploring Snowdonia and the rest of North Wales. Guests can enjoy steam trains, dog walks, easy rambles, climbing, fishing, industrial heritage, nature and stunning open views all within walking distance. The owners moved into Bryn Elltyd 6 years ago to escape the city, live a lower carbon life style, be more in tune with the planet and leave a cleaner legacy for their grandchildren.

Eleanor Pratt the Green Tourism assessor said, “The excellent use of renewable energy throughout the business is a highlight, with a new high-tech biomass boiler installed, and continued use of solar for hot water and electricity. The building itself is exceptionally well managed and well insulated. There is excellent use of home grown and local produce, and the garden is well designed to support and encourage wildlife. In addition, John and Celia are heavily involved in spreading the green message by working with other business owners and organisations to share information and best practice.”

Project Description

The business conducted a heat loss survey using an infra red heat sensor with Superhomes, This helped identify insulation projects to be undertaken at this 1883-built ex mine manager’s house. Sheep’s wool insulation was used together with Kingspan and fiberglass in the main house, achieving an insulation level equivalent of 700mm of rockwool, and a u value of less than 0.2W/m2/oc. The whole house and external rooms are superbly lined with either sheep’s wool, sempatap or Kingspan. Attention to detail has included lining the backs of cupboards and wardrobes, helping to reduce the heat loss from the building dramatically. Windows are double glazed with UVPC. Some external rooms are covered in insulated turf roofs, and a sedum roof is in place on the bike store, itself built from recycled materials.

All energy inputs used for heating, electricity, car charge points, sauna etc, are from renewable sources, making Bryn Elltyd a carbon neutral business with regards to energy. A biomass boiler uses carbon neutral wood fuel for heating, with the interior boiler house wall doubling up as a radiator back into the main house. Solar thermal and PV arrays heat hot water and provide electricity. In addition the business purchases renewable electricity from Good Energy meaning that all electricity has zero net carbon emissions, including that supplied to the on-site electric car charging points.

Additionally carbon impacts associated with water use (see the new Green Tourism carbon calculator) have been minimised at Bryn Elltyd. The site uses an innovative rainwater harvesting system to flush toilets, and the on-site ecological digester and reed-bed treatment systems help negate the impact of sewerage infrastructure and water treatment, further aiding the owners’ achievement of a minimal carbon footprint for the site.
