“Show & Tell” of items (<£50) to make homes cosier, cheaper to run, or more sustainable + YOEH's inaugural talk

First things first: Thanks to Native Architects for giving a great talk last month as the inaugural event of the York Open Eco Homes series (YOEH). It was a insightful talk, followed by a Q&A session with lots of good questions and discussions. Our next event will be a “show & tell” session where anyone is welcome to come along and talk about a item for less than <£50 that has made their home cosier, cheaper to  run, or more sustainable.

Building Low Energy, Healthy Homes –  A talk from Native Architect’s for YOEH’s inaugural event

Sally from Native Architects gave a talk with insight into successful eco building projects from renovation to new build. There was a lot of discussion on use and choice of materials. The highlight for me and possibly others in the room, was hearing about eco-building for a bottom up perspective that few people get the opportunity to do. There were many interesting digressions prompted by audience questions including sally highlighting historical lessons from eco-architecture ( for instance cold bridging, even evident within St Nicks’ environment centre). Having samples of low energy construction materials (such as Pavatherm and Pavadentro) made the evening a hands on experience!

Topics covered included net CO2 emissions per kg of material. With a nice graph on one of the slides showing how emissions generally led to materials being ordered (in emissions terms): “natural” ( with strawbales etc being negative )  < ceramic < synthetic (e.g. plastics) < metal. The audience was also shown spider charts highlighting how multiple characteristics of a materials should considered ( e.g. breath-ability, thermal conductivity and density) to find the right materials or fairer compare multiple materials. The role of influencers on a project or on product choice was also mentioned ( e.g. salesman, contractors and consumers).

Lots of time was given to successful strawbale projects Native Architects had undertaken (e.g. Bodner House), and lime plastering (including some fun photos of a workshop for stakeholders). The challenges for choosing bio-based construction also were discussed. Namely high profile mistakes, poor installation, lack of individual research into building materials, industry inertia, certification processes (e.g. BBA) and of course cost.

The talk was well received, with good questions throughout. The Q&A session was vibrant with lots of questions on approach and materials. YOEH thank Sally for giving a such a fascinating and insightful talk.


“Show & Tell” – YOEH’s next event.

Simply put, there are lot of cheap actions that can be done to make our homes cosier, cheaper to run and more sustainable. However, some of them work better than others and its often experience of lesson learned that we work this out. This is therefore a opportunity for people to share cheap solutions that have worked and maybe could work for someone else. Some ideas could be chimney balloons, compact water butts, energy monitors, small insulation works, etc…  I am looking forward to hearing about everyone’s items.

I am continuing being told being eco is expensive, which I find bizarre as a lot of the measure I and other York Open Eco Homes participants have done are cheap or they have saved money by doing them (sometimes alot!).

This is event is open and hopefully will allow everyone present to learn from each other. I just ask that you please message me in advance by email(littleecoterrace[at]gmail.com)/twitter etc if you would take part… Personally, I would love to do a talk on using open source motoring (e.g. openenergymonitor), but this is more around to ~£150 so will have to wait for another event. Instead I will talk about my chimney balloon and how to install it. Other items people have volunteered to talk about so far include: draught curtains, a competing “all natural” chimney “sheep”, and an upcycled wood cutter.

There are speakers and ideas in the pipeline for future YOEH events, please do contact me if you have any ideas for speakers or events you might be interested in.  I look forward to seeing what people bring, and I hope you can make it!
