Next meeting: February 23rd Feb - Whole life-cycle carbon in retrofits. john Preston to lead a discussion on whole life carbon in retrofot. John is Historic Environment Consultant, and Heritage Chair of the Sustainable Traditional Buildings Alliance. He asks: Has anyone in the group carried out a whole life cycle assessment of their retrofit project? What is the carbon cost of retrofit measures? How long will they last? Will they need to be replaced before 2050 (or any other Net Zero target)? How can we maximise the lifespan of materials? These are some of the issues we will explore in this session
We conduct meetings online using Zoom. All welcome, contact Nicola for the link.
The energy group have a completely new energy advice tool which you can use to get ideas for improving your home. The suggestions update dynamically according to your aims (indoor air quality, keeping warm, reducing bills, carbon emissions, keeping cooling in summer) and what you already have in your home. Please do try it out.
At our April meeting we started a discussion on what a low carbon Cambridge might look like and how to get there. The plan is to make a list of possible strategies, whittle this down to 3 or 4 that are practical and will make a real difference, then see what we can do to promote them. Needless to say, we didn't manage all that in one meeting! Our list of strategies includes:
Would you like to take part in this discussion? The notes are in a shared document on google drive but I can't give you the link here for fear of spammers. You can access a readonly (pdf) version here . If we know you and you would like to take part let me know.
You can read suggestions from some Energy Group members here. Suggestions are ordered by cost - three of them are less than £100.
Read out latest fact sheet: how to keep cool in the summer time. From keeping windows closed in the summer time, to DIY awnings, and ice packs for the head.
Nicola has written an overview of embodied energy/carbon issues including how you measure it and what are the implications. For example, in some cases (like conventional cars) operational energy dominates, in other cases manufacturing or materials (like carpets). In other cases both are important. The report includes comments issues raised in our discussion on the topic. Read it on her website here
Nicola has written an overview of the circular economy and what we can do to promote it. (e.g. get your stuff mended professionally, consider renting rather than buying stuff). This includes comments issues raised in our discussion on the topic. Read it on her website here
