Housing is a major contributor to CO2 emissions in Europe and America today. The construction of new homes offers an opportunity to begin to address this issue. Carbon has a twofold role: the first is the responsibility to make informed decisions of the embodied carbon of the materials we deploy in buildings, the second is to sequestrate free carbon and hold it in the fabric of building stock. Building Information Modelling (BIM) allows to measure the metrics, analyse the performance and simulate alternatives before they are executed. By branding the role of the technologist, through technology, a similar path can be taken to establish the title and build a robust and well-founded plinth upon which to promote technologists undoubted skills. Besides the technologist, and also in tandem, BIM has a need to re-empower architects and managers so that they can regain the overall command in the design process. Building information into models is the rightful domain of the technologist.
