I've refurbished commercial buildings in the past for use as vet surgeries and always been disappointed with the energy requirements. Im planning to build the first PH vet surgery in the UK and this was a preliminary exercise to help decide whether to refurb or demolish the existing building. This was my first Passivhaus project and also a first for the architect. Finding details for retrofitting a semi-detached building to Passivhaus was a challenge because the neighbouring building had no such measures. Myself and partner proved excellent at airtightness measures and will be confident to oversee this in future projects.

Energy Use


  • Passivhaus software (PHPP) predicted heating demand of 1500 kWh per annum for the house.
  • ​Over the last 2 years the house has used around 2000Kwh p.a. for heating, cooking and hot water and around 1000kwh of electricity whilst generating 3000kwh p.a. from solar panels. 
  • ​Typically, in the UK, a house of this size uses 12000 kWh of heating and 4000kwh p.a.electricity.
