Build Insight are working with Norfolk company, Beattie Passive, on an innovative retrofit build system that can reduce heating bills on cold, poorly performing homes by up to 80%. The new system is called TCosy™

Build Insight are working with both Solihull Community Housing, who own the block of 6 flats, and Beattie Passive to ensure the project complies with the Building Regulations.

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.
