Event: Retrofit Detailing from a Builder’s Perspective

Bill Butcher has a lifetime of practical building experience including over 30 years of thinking about buildable detailing for highly energy efficient homes. In this webinar he will be exploring some key details he has worked on in deep retrofits and inviting feedback and discussion. We should never stop learning, so Bill is always keen to share his long experience and to learn from others’ experience too.

Bill co-founded 21°, formerly Green Building Store, in 1995 which has evolved into a leading national design and supplier of Passivhaus windows and doors, MVHR ventilation systems, and airtightness products.  He has led on the Company’s pioneering Passivhaus projects, including the Denby Dale Passivhaus, as well as developing a Passivhaus approach to a number of radical retrofits. Having originally trained as a Quantity Surveyor he has over 45 years of practical building experience. His pioneering work on the Longwood Low-Energy House in the early 1990s was the beginning of his low-energy and Passivhaus journey.

As a Certified Passivhaus Consultant, much of his time is taken up with giving pragmatic building advice to clients, designers, and builders as well as lecturing and training with Coaction.

Bill is a passionate advocate for better building in the UK, seeing the Passivhaus standard as exemplary for the UK industry in meeting its climate change responsibilities.  He is committed to making the lessons he has learned from Passivhaus accessible and easily understandable for the wider construction industry.
