Retrofit for Social Housing - Solihull, Birmingham

The project partners are:

  • Beattie Passive - inventors of the patented TCosy™ Retrofit build system
  • Encraft: energy consultants and Passivhaus designers, who are the TSB lead partner
  • Coventry University: for tenant involvement and assessment
  • Solihull Community Housing: a subsidiary of Solihull Metropolitan Borough Council, who own the block of 6 flats to be retrofitted

Beattie Passive is actively involved with a project for Social Housing in the Midlands using its innovative Retrofit solution TCosy™ which provides a fast, low cost and highly replicable solution for a wide range of buildings. The TCosy™ dramatically reduces energy requirements, creates a healthier living environment and can be delivered whilst residents remain in their home.

The project has a three stage approach:

  • Analysis of tenant energy usage pre-retrofit
  • Retrofit of apartments block containing 6 flats
  • Analysis of tenant energy usage post-retrofit

Project Background: Work to date has largely involved Coventry University who have installed monitoring equipment for the acquisition and analysis of pre-retrofit data of tenants’ energy usage. Once Beattie Passive has completed the physical TCosy™ retrofit in mid-2015, the tenants’ energy usage will be re-assessed during the subsequent winter heating period.

Project Benefits:

  • The project will deliver CO2 savings, typically in the range 2-4t CO2 per year per dwelling. On realistic assumptions of rapid scale up to 1000-5000 properties a year, will contribute up to 20,000t CO2 savings a year to the national effort to reduce CO2 emissions.
  • There is minimal disruption to residents as they remain in their homes for the duration of the retrofit process.
  • Energy bills will be dramatically reduced and residents will also benefit from an enhanced and healthier living environment.
  • The approach provides training and labour opportunities local to projects which will have positive impacts on social inclusion and long-term economic benefits for local communities.
  • The project will develop models for best practice in tenant and community engagement, ongoing liaison and feedback loops which ensure energy use is optimised but also ensures tenants and communities are happy with the outcomes of the project.
jerico Foundation

The Jericho Foundation are a social enterprise that work with people who experience significant personal or occupational barriers to employment, training or social inclusion. Their aim is to provide these people with the skills and experience they need through a range of social enterprises. Jericho Construction are working with Beattie Passive to manufacture the timber frame for the Solihull Retrofit project, developing the skills and knowledge of the trainees.

“What every retrofit project needs is a low risk, whole building approach, capable of delivering superior thermal protection and air tightness, as well as fit for purpose heat recovery ventilation. Beattie Passive’s TCosy™ does all of this and more.”
