I created this topic because I know insulation prevents heatloss and can save energy when utilised , yet this morning I read here in the Guardian how householders aren’t improving energy efficiency after insulating.
This is the article here.
[“‘Rebound effect’ cancels out home insulation’s impact on gas use – study | Energy efficiency | The Guardian” ‘Rebound effect’ cancels out home insulation’s impact on gas use – study | Energy efficiency | The Guardian](“‘Rebound effect’ cancels out home insulation’s impact on gas use – study | Energy efficiency | The Guardian” ‘Rebound effect’ cancels out home insulation’s impact on gas use – study | Energy efficiency | The Guardian)
Reading it prompted me to think about our experience with insulation and where we’ve noticed the benefits and struggled with the complexities of insulating - mostly around installation and things we didn’t understand, such as moisture and damp - all of which we experienced and learned about when installing insulation in our cold loft - an experience we documented here in the forum.
Having lived in a large draughty house over a few winters now , we know where our efforts are best focused and fully understand the term ‘thermal envelope’ and how achieving this in a room will prevent heatloss and pentrating cold. We also understand which rooms in our home are the most temperate and naturally sheltered through the seasons - these are rooms nestled between other rooms, with smaller windows and less external wall space - we utilise these rooms the most.
We’ve experimented effectively with draughtproofing and various ways of heating - using whole house heating v one room, gas central heating v one electric radiator, as well as how to heat the person not the space.
Watching the smart meter has certainly been a good guide to what is cost effective. Initially determined to help our planet by reducing our carbon footprint, it is now the need to save money, which is driving us harder still to look more closely at how we keep warm and remain energy efficient
Currently, we don’t use the whole house gas central heating - we can’t afford it. Opting instead to heat the room we’re sitting in via an electric heater; it’s much cheaper than the gas and we’re still comfortable.
Recently, we learned about the science of layering clothes and have invested in merino wool base layers -these are a revelation - successfully keeping us warm without any heating on.
Being a keen hiker and lover of the outdoors, it was this article, which resonated with me and prompted me to invest in insulating our bodies as a more cost effective means to keeping warm . This investment has proved most liberating from the shackles of the energy companies.
The previius article about’ insulation not reducing energy use’ I think is about people with no interest in it. Likely they take energy use and comfort for granted in some way.
Meanwhile, for those who are interested, I thought I’d share my experience here.
To sum up our journey so far, we will be insulating one of our bedrooms located on two exterior walls as soon as financially possible. Costs for this will include solving the penetrating damp problem, before we insulate. Meanwhile and most importantly, we are cost effectively comfortable and warm and have dramatically reduced our carbon footprints as well as our bills in the process too.
Best wishes everyone. Here’s to energy saving, keeping warm, liberation and helping our beautiful planet all at the same time.
