You risk melting if you greendeal you home

[ktech]

Interesting report - if you greendeal it might me great in the winter but you will melt in the summer!
BBC News - Green Deal 'could lead to deadly summer overheating'

The answer is Air Conditioning :banghead:

What a crock of ...
Insulation keeps the heat out as well.
Have the BBC hired some Daily Mail hacks?!?!

Good example of this is that new Skiing complex in Dubai :smilielol5:

 

[snowhead]

Do they seal up the Windows and cut off householders arms in Green deal then??

 

[zeljuga]

Naah .Arms goes as replacement stock for the GM hospitals.

As Archy says, I was under the impression that insulating kept homes cooler in summer as less heat is absorbed by the property.

 

[Gavin A]

I think this could actually apply to internally insulated houses as they lose the function of the thermal mass from the walls to moderate temperatures, so will heat up much quicker in full sunlight.

This'd be one of those situations where having someone who knows what they're doing giving advice rather than a newly qualified GD assessor would be useful.

If you stop the heat from entering the home, are you not preventing the problem?

 

[Silly Sausage]

I must admit, I didn't read the article properly, so there could be some truth in it!
But on hot days, where do you go, inside out of the sun.
My loft (insulated) is probably hotter than one of Tony's furnaces these last two days though.

But where's it insulated?

At the ceiling level stopping that heat getting into the house?
or
At Felt / Membrane level, thereby heating the house up via the ceilings ?

Slate roof, old black felt and about 200 mil above the ceiling.

 

[Worcester]

It'll got hot then (very hot :devil: ) - put some PV on it, that will shade the roof and your loft temperature will go down

 

[Silly Sausage]

Haha!
Well, if you want a show house for PV up in Manc, I'll be more than happy to accommodate you!
E-W roof. With this sun I could be generating MWs!

 

[Gavin A]

true in a house with only north facing windows, but if you're creating a highly insulated box with very low thermal mass, and big south facing patio doors and windows, or big velux windows.... scorchio

The issue is easily addressed of course via a wall mounted solar PV array above said patio doors to provide summer shade to the windows while allowing for full solar gain in winter.

 

[SolarCity]

Are windows where most of the heat enters a home in the summer then? Is this not negated by using blinds?

 

[telectrix]

i'd like to see the itchy-poo monkeys do our loft. it'd take 'em 3 days to clear all the junk out. kingspan between the roof rafters is the logical way to insulate a loft, but the cost is horrific.

 

[Gavin A]

Are windows where most of the heat enters a home in the summer then? Is this not negated by using blinds?

yes, and yes to an extent - that'd be one mitigation measure that could be used to mitigate the issue. Best bet is some form of external shade over the windows to shade it in summer, but allow the light in in winter, though blinds would be cheaper.

love it

you see these on commercial buildings, they have a fancy french name : brise soleil (means sun breaker ) Brise soleil - Wikipedia, the free encyclopedia

hmmm, 3,000 extra deaths 'may' occur per year by 2080 from homes being too warm against the 20,000+ deaths that are actually happening every year from homes that are too cold. BBC News - Winter death toll 'falls by 8%'

 

[telectrix]

well, i ain't greendealed the house and i'm melting anyway. the house is crying out for solar, roofs SE and NW. but her indoors don't fancy it.

tell her ill install ac if you let me, there are some cheaps kits now

My house is hotter than the sun.

The split-second just after your body starts to spontaneously self-combust - I reckon this is what it feels like.
