Evidence-based building performance services from an independent consultant

I monitor what occupants actually experience: CO₂, particulate matter (PM2.5 and PM10), temperature and humidity, using calibrated sensors. You get a clear report showing where your building falls short of recommended levels, why, and which fixes to prioritise. Better ventilation and comfort support healthier, more productive occupants.

I look at how your building uses energy and compare that with how it was designed to perform. By matching HVAC, lighting and ventilation to real occupancy patterns, I help you find waste and focus spending on the measures most likely to cut your energy bills.

I help you improve the building envelope using building physics rather than rules of thumb. That covers insulation strategy, U-value calculations, glazing and ventilation options, and material selection. Each recommendation is weighed against comfort, energy savings, moisture risk and budget, so you can invest in your retrofit with confidence.

As South Africa's first Certified Passive House Designer, I apply Passive House principles to new builds and deep retrofits: a continuous thermal envelope, airtightness, thermal-bridge-free detailing and efficient mechanical ventilation. The goal is a building that stays comfortable all year with very low heating and cooling demand.

I can take your project from assessment through design to delivery. I coordinate contractors and suppliers, keep scope, cost and programme under control, and check that the building performance you paid for is the performance you actually get.
