The scope of a building performance study can be adapted to suit any project or budget and is useful on a building of any size. John also explains how through open days and local engagement, momentum for retrofit at neighbourhood scale has resulted in a pilot project with Kate Raworth\u2019s Doughnut Economics Lab.<\/p>\n<p>In 2013, John <a href=\"https:\/\/www.architectsjournal.co.uk\/archive\/zero-carbon-house-by-john-christophers\" target=\"_blank\" rel=\"noopener noreferrer\">retrofitted and extended a two-up two-down Victorian terraced house<\/a> in Birmingham\u2019s Balsall Heath neighbourhood, adding Passivhaus levels of insulation and triple-glazing.

He has collaborated regularly with Associated Architects over the years, designing numerous Passivhaus projects, including most recently the Green at St Richard\u2019s Hospice, shortlisted this year in the AJ Retrofit Awards.<\/p>\n<p>John began as the practice\u2019s green champion back in the 1990s, later launching a green team. Today John increasingly works client side as a sustainability champion and design advisor.
