Certified Passivhaus Consultant specialising in retrofit master planning. Main areas of work are:

• Master planning for retrofit projects. This involves detailed baseline energy analysis using Passive House methodology (PHPP) and thermal bridge modelling, followed by an action plan of improvements that enables individual homeowners to plan towards specific space heating demand targets. The plan is not only about the energy analysis that we do ourselves, but also involves coordinating with other specialists as needed in order to progress the planning (e.g. for MVHR design, hot water / heating / renewables design, structural analysis, window & door schedules, and moisture modelling). For certain building constructions and locations, we are able to also carry out WUFI (hygrothermal / moisture) modelling in order to check what would be a safe construction in terms of moisture risk, given the planned thickness / type of insulation and type of airtightness layer.
• Training of contractors and architects in Passivhaus and low-energy building techniques for retrofit and new build. This takes place both in person and online as part of Coaction CIC, a group of trainers running Passivhaus Tradesperson and Retrofit Delivery courses.
• Ad hoc work related to low energy retrofit. This includes training and mentoring (e.g. one-on-one training, CPD training, or site visits), checking PHPP calculations, and one-off thermal bridge and u-value calculations.
