They've installed much the same at our store, albeit with sliding doors on the sides as well, and it is purely for heat loss reduction/energy saving.

They've gone mad over saving the odd penny here and there - mainly, it seems, by replacing light switches with motion sensors which turn the light off in the loo after eight seconds - bloody useless - and by sticking up "SHUT THAT DOOR" signs everywhere.

Hm. Helpful.

Manchester's Tesco Metro on Market Street has no doors. They've had to bring in loads of industrial heaters in , all placed in big crate-trolley things (the metal things they normally have loads of items in all stacked up to move them round the shop and stuff). so no one gets burnt. It's still a bit chilly in there though.

BOOKS have been writing on the subject. Anyway, one interesting reason why it is said to be important is because "the sudden volume of rushing air [with normal doors] can be so great as to blow out windows". Sounds like a load of old rubbish to me, I've done them the courtesy of adding {{uncited}}.

You're wrong.

The sudden rush of air principle pertains mainly to skyscapers. Because the stairs and lift shafts aren't completely sealed, the rush of cold air caused internal doors to slam shut and windows to shatter higher up the buildings due to the difference in air pressure.

The other thing with revolving doors is that even though a relatively small volume of cold air is being deposited on the inside, it always comes in at the same speed even when it's blowing a gale outside.

So you can remove your {{uncited}} now.

Err, no. Even if it's true, it remains uncited.

Before my local Asda was rebuilt, they had a revolving door where the partitions could be folded flat in the middle (they were hinged) so people could walk freely on both sides. A nightclub is a stupid place to have a revolving door anyway.

Speaking of Tesco stores without doors, has anyone noticed how quite few Tesco stores have been including sort of porticos that surround the front entrance?

I suspect this is something to do with stopping the heat problem you speak of, although it seems more likely it's purpose is to prevent ram-raiding et cet.

My local Tesco has just had one of these added and it's absolutely useless. I went in there last week, and it was colder in the shop than it was outside. A complete waste of money. Apparently, the managers at my local Tesco have a strange heating policy too. The heating stays off until November 1st, when they turn it on in "exceptional circumstances."

When I went in, the heating clearly wasn't on - possibly because it wasn't cold enough to justify it, or perhaps because they just threw money down the drain for a new entrance. I'm sure there's some form of legislation somewhere governing temperatures in places of work.

The worst one is at Touchwood in Solihull, it breaks down regularly and has no glass in the door, making Starbucks cold.

Or we could just cite Chie as the source.

Well that's the Midlands for you. What do you expect?

They have built these onto the Cambridge stores of late. I think they have done them all now. Confused me initially, I'm so used to walking straight through. I wondered why they had done them but makes sense. The whole bit about having the huge entrance must make parts of the store freezing and not very conducive to a good working environment.
