The Long Green retrofit is a step-by-step deep retrofit of a typical 1960’s bungalow to the Passivhaus EnerPHit Plus standard. The goal is to take a dwelling like so many others and demonstrate what can be achieved, sharing the journey and the lessons learnt along the way. We aim to take a mundane and tired building and create a comfortable, healthy and efficient family home. Following the Passivhaus Principles and having modelled the scheme within the PHPP, we will in time, be upgrading all of the floors, the cavity wall insulation, loft insulation, adding EWI, replacing all external doors and windows and extending the property to Passivhaus standards. New heating, new MVHR and greatly enhanced airtightness will all contribute to improved performance and comfort.
The project is currently on site, with some works to the existing house completed and the Passivahus extension nearing completion. There will be detailed drawings and some construction mock-ups to review as well as a tour of the elements completed. I'll also have construction materials on show and the opportunity ot play with airtight tapes and membranes for those that want to. It is therefore a great opportunity to talk to the PH Designer/ Architectural Technologist/Self-Builder about the real-world experience of retrofitting/building to Passivhaus standards.
Tours will last about 1 - 1.5hrs and will be limited to ten people per tour with, initially, one on Friday and one on Saturday afternoon. If there is a good amount of interest I will add more – please contact me directly if you are unable to book or cannot make those days – matt@nwdarchitects.co.uk
