Sally’s early career as a building services engineer focussed on renewable and low energy systems for a diverse range of sectors including historic, industrial and educational buildings. Life as a services engineer was too easy-going so she set up WARM with her father Peter in 2009. WARM is an energy consultancy providing Passivhaus design advice and certification but also dabbles in building services, training, monitoring and anything else that improves the built environment and looks interesting. Sally particularly enjoys creating buildings with good internal comfort, preferably without extra cost.
