Last Tuesday morning we visited our ‘towards Passivhaus’ Retrofit-for-the-Future project at 3 Passfield Drive in East London to take some thermal images of the finished retrofit. We wanted to take advantage of the cold snap that is being experienced across the country to check the thermal performance of the building.

At 8.30am on Tuesday morning the outside temperature was 1.5°C. The thermal images of the front facades of Passfield Drive, shown above in Fig 1, are a powerful visual indication of just how much energy this retrofit is saving.

New Passivhaus triple glazed windows and doors have now been expertly fitted to the north elevation of 3 Passfield Drive (wall insulation will follow soon). The excellent thermal performance achieved by these windows and the draft-free fitting can be clearly seen in the thermal image of the north elevation below. Comparing the ground floor window of no. 3 to the neighbouring property on the left it is remarkable how much better our house is performing. The same can be said when considering the difference between the new front door of no.
