Planning Your Retrofit

Planning Your Retrofit

Fri 8 Oct 2021, 7:00pm – 8:00pm

These 2 talks and lively discussion attracted a good audience, who were very appreciative. See below for Slides & Video of the whole session. 

Are you interested in improving your home’s energy efficiency and comfort, but a bit stuck on getting started or planning what to do?  This free 1 hr online talk aims to help you make progress.

Bart Hommels, physicist and previous OEH Host has done a thorough, largely DIY retrofit of his 1940s semi-detached family home, with a Passivhaus extension. The results are delightful with much lower carbon emissions. See his Case Study for details.

He started with ‘easy win’ jobs, like insulating the hot tank and hot water pipes, which he’ll describe more generally.  They’re a great way to get started and motivated, while paying more attention to your home and what you want it to become, whether you’re an expert DIYer, like Bart, or definitely not. Some ‘Quick Wins’ involve using and controlling your home more carefully.

Then Bart got professional help in developing a Whole House Plan to guide the major work, as described more by Carl:

Carl Dodd is a Retrofit expert with 28 years’ experience of designing and often managing eco-retrofits and new-builds, including a previous OEH home, that combined 2 semi-detached houses.

He’ll talk about and discuss:

  • Your values and what you want from you home
  • A Whole House Plan: why it’s needed and worthwhile
  • The PAS 2030 standard and how Retrofit Assessors and Coordinators help
  • Retrofit in one project or in phases ?
  • Ways of finding professional help

The talk will have time for questions and discussion to help you get going with your plans and eco-improvements.
