During his tenure as energy minister Eamon Ryan instigated plans to energy upgrade Ireland’s draughty, damp housing stock. Ryan and his wife, writer Victoria White, show Construct Ireland how their own home has been given the green treatment, and architect Mike Haslam of Solearth describes the project.
