I am the director of Earthwise Construction, with over 20 years’ green building experience. At Earthwise we work with home owners, architects, developers and businesses across Bristol and the South West, offering comprehensive eco-design & build services, and specialising in Passivhaus timber frame new builds and whole house retrofits.We also have a ventilation arm of the business, specialising in Mechanical Ventilation with Heat Recovery (MVHR) and we design, supply, install, commission and service high-end and mid-range MVHR systems. We also supply and install Demand Controlled Ventilation (DCV), which is a fantastic ventilation solution in renovation projects or those where space and/or budget could rule out installing MVHR. We offer MVHR and DCV to clients across England and Wales.In addition, we offer heating and cooling options for eco builds, such as far-infrared heating panels, and we sell a range of products in our online shop, including airtightness products (we’re a Pro Clima stockist), MVHR filters and MVHR components. Clients can arrange to visit our showroom in Bedminster, Bristol, which stocks all these products, and has working MVHR and DCV units.Minimising environmental impact and maximising energy efficiency is at the heart of everything we do.
