Eco-technology Show at the Brighton Centre

Two days of exhibition stands and talks all about saving the planet by reducing our use of carbon based fossil fuels.  The whole ground floor was dedicated to super  motor cycles and fast cars – that use electricity to show just how great a person the owner is.  After that I began to wonder just how ‘green’ this thing was.  Upstairs heard from a man who decided to make the most of his array of photo-voltaic roof panels by buying a £30,000 electric car.  He has not bought petrol since owning it.  The planet is safe in his hands.

Meanwhile the big thing of the whole show is the new government scheme to offer us all money if we install biomass heating, or solar hot water kit, or even an air or water heat pump to heat your home.  This is the Renewable Heat Incentive.  But to install any of this without reducing the rate of heat loss from your home would  be a bad thing – so you have to show that you have reduced that rate.  the best thing for this is to insulate walls (after draught proofing, double glazing (or just thick curtains), reflectors behind radiators and the vital loft insulation).  After much thinking I am seriously considering insulating my walls.  No cavity so it could be on the outside.  I’ve been looking at several jobs about the town.  Here is one that has been happening since early June.

Then corner and edge reinforcing strips and a plastic mesh stuck on with a special plaster.  Fancy details can be recreated with extra polystyrene, like the windowsill.

Then a self-coloured plastic paint/plaster finishes the surface.

Thinner and tougher plastic foam has been stuck to the lower wall and coated with similar plaster.  I could probably have this done at home (front and back, with pipes moved and roof extended to allow for the extra thickness) for about £13,000.  And I’d get £6000 cash back.   And I’d be responsible for less carbon dioxide in the air.  The annual heating savings should repay the cost in about 9 years –  so I have to last until I’m 74.

Seems like a reasonable target.
