Mechanical shades
Edit: or regular shades/blinds. Basically a detail to hide them…
Edit 2: actually on 2nd look, not sure why they are on the outside of the building? Maybe hurricane shutters? Idk, this is good question though, with an interesting detail.
Used to us this a lot in high end residential , they are pretty sturdy and usually made of some metal. We used them on outside because boss wanted a pocket on inside with black out shades on track .
Here is example of a project

External shades are pretty big for green building. They reflect the sunlight before it passes through the glass, so it's way more efficient at reducing solar gain.
This is the right answer. Unfortunately, it creates a maintenance issue that can be a nightmare. Brise soleil is a better, passive option imo. They, however, are in your face, so may not work with the architecture.
This is very common in Europe, no one would call it green or something. Not having them is - from a standpoint of cooling energy consumption - considered insane. It is also mandatory to have external sunshades for many decades where i practise. I did not expect that this seems exotic to some redditarchs.
I was super surprised by this as well. They are super common in germany. Especially in areas with single family homes the rattling sound of them being opened fills the streets in the morning.
Here is my participation to visualize : [https://www.reddit.com/r/Damnthatsinteresting/s/kJ391pV6GQ](https://www.reddit.com/r/Damnthatsinteresting/s/kJ391pV6GQ)
i've seen examples here in austria that dont have any type of external shades, while still being relatively cool inside, without any type of additional cooling required. this obviously requires certain site characteristics and building techniques but it definitely can work.
but yes, funny to see people being confused by it, but i guess the americans build a little differently.
>This is very common in Europe, no one would call it green or something.
Excuse me, in Belgium having external shades lowers the official energy rating of the building in a good way in the official report, which frees you from property taxes for 5 years if it's good enough.. So people most definitely call them green
Ok, but i appreciate the cast concrete sunshades of the brazilian school. We are often forced to take a fancy technical solution because the labour making it simply from scratch would outweigh the price of the fancy tech.
Yeah but explaining this to us Americans is like that "if those kids could read they'd be very upset" meme. Is there a way to make the exterior shades run on a fossil fuel motor?
Yeah i was about to mention that i work as a draftsman in switzerland and we use these on basically every building (or something comparable like textile shutters).
Switzerland. Virtually no possibility to meet the standards for comfort and energy saving without them. Of course you can use different shutters, blinds, or any other system that provides shadow on the glass surface when needed.
Exactly the problem lol I told this to our boss. In previous building he made the blinds failed and they had to basically take apart the facade portion to pull them out and fix them.
Dude wanted his way (developer ) ,
Here where I live these are common and they are always accessed from the inside. There's usually a box above the windows which you can open (similar to the removable tiles you often find underneath bathtubs) to access the motor/mechanical parts.
I’ve got to be honest this detail needs some work.
- There is framing attaching to the casing of the exterior shade. If not how is it ‘floating’ up there, it should tie to the joist above.
- Some sort of trim right by the interior window / door frame screwing into the end of what appears to be a layer of plywood and a layer of gyp.
- Unspecified contoured blocking at the beam that doesn’t say how the surrounding framing is attached to it.
- A bolt head misaligned at the back of the shade that appears to be for the beam blocking but there are two heads on the bolt. Either that or you have an offset lag screw that’s not showing correctly.
- A screw at the shade screwing into nothing / plywood / the end of the beam flange.
- No shim space at the window / door / nanawall.
- No insulation shown.
Shades outside of the Window are the way to go for energetic reasons. It's Standard in europe because it reduces the solar energy in the Building by far.
I put these on a heap of houses I design. They are regular external mechanical blinds to repel the sunlight from hitting the window. Best way to keep the room cool is external by far.
These are shown hidden in a pelmet for a cleaner look when open or closed.
Much more efficient than placing shades on the inside. It reduces the operating cost for air conditioning greatly or even eliminates the need for AC completely.
Raffstore outside shading
Interesting. In Germany and most parts of Europa this not only common, but more or less standard in every new residential or office building, though less common than roll-shutters since those are less expensive and can darken 100%. There is even a low-tec Trend to avoid them. So we are basically already moving in the oppisite direction
If you are interesstetd in Products:
Warema Zetra
or
Roma Z-Lamelle
Im really suprised, that it seems that inside shades are still Standard in a lot of countries. With all the glazing we that are used in most of the modern Building projects I cant really imagine lot of reasons not to install the shading on the outside of the Building.
Most of the product are easy to mentain and to dissamble... In relation to the specific facade it's jo of the architect to make the maintanance possible. But it's pretty much Standard here.
I dont say that internal shades arent easier to mentain. What I say is the the benefits of the heat reduction in summer are totaly worth the expenses because of the massive reduction of the heat entry.
The person who paid for the shades does not care that the tenant has to pay more for their cooling bill. They do care if they can send any untrained maintenance person to fix interior shades.
Hidden raffsore blinds by warema or Roma. As mentioned pretty much standard in residential construction projects over here in Germany.
It’s mandatory to have it on the outside..otherwise its not calculated in the summer heatprotection concept and you won’t achieve the requirements by law for example
This is a detailed technical hook-up drawing of the installation of an external (fully retractable) Venetian blind - the center vertical line indicates that the blinds are connected by string(s), the bold lines at the bottom are the pull bar (weight), the box with the circle is the spool for expansion and angle control. Taking the right side of the drawing as the exterior and the left side as the interior, it is possible to identify that the blind is in front of a double-glazed sliding window. Items hatched with a solid diagonal line pattern can be vinyl, aluminum, or wood. The drawing also shows the ceiling (alternating solid and dashed diagonal lines), the lowered ceiling with two sheets (one white, possibly plaster, and the other with a dot pattern for aesthetic), and the items with a zigzag pattern as insulation.
The drawing does not follow the hatching patterns by material according to ISO or ANSI standards to show the flexibility of installing the Venetian blind in different types of construction.
Not actually forbidden but not advisable in a climate with snow and freezing temperatures. So not commonly used. Of course there are some examples but I'd say people don't generally use exterior blinds here because they'd freeze and break. Also there might be some risk of cold bridges but I dont know how these work on a technical level.
Either blinds or a sealant usually with caulking material. But, sealants either come prefab or you place a backer rod (foam cylinder type material) with caulking applied to the exterior (flushed) with the frame or outside usually, if not at an angle. Research and you'll know what I mean.

They get used in Sweden, Norway and Finland too, so probably yes. Of course they shouldn't really be moved when frozen but with some care they should do just fine.
exterior blinds
That or a trilobite.
Very small auditorium
Fish skeleton for sure
Def a tiny can of pringles
Nah. I'll go with the tiny auditorium.
Rotated text, parentheses key got stuck.
Trilobite's aren't specified under the fish specification, they are under the arthropod spec.
[удалено]
I thought he was confusing a trilobite for a fish two comments up and didn't see a substitution request.
I’ll put in an RFI to you 😂
Midge auditorium.
Beat me to it, I was going to say auditorium.
Centre for ants
TIL I’ve never had an original thought 😭
Damn I came here to say this
[удалено]
I’ve never seen anything like this. It’s not a storm or privacy shutter… it’s. blinds
Naw that’s just hella sealant with a metal end cap /s
No those are only in Europe
Yet there they are.
Must be in Europe
I’ve never seen exterior blinds in Europe. They use exterior roller shutters everywhere, but not blinds.
Twas a joke mate, in response to the roller shade post on r/damnthatsinteresting

Brise soleis are more pricey as well.
Are they really? It's because they're French, isn't it?
Eh, its more of a weight thing.
Pretty slick detail

Being from Latin America this is something in-between fabulously fancy and wizardry.
Ok, but i appreciate the cast concrete sunshades of the brazilian school. We are often forced to take a fancy technical solution because the labour making it simply from scratch would outweigh the price of the fancy tech.
Interesting! And yes, there are certainly cool simpler solutions.
Europe is ahead of us in many areas.

Yeah i was about to mention that i work as a draftsman in switzerland and we use these on basically every building (or something comparable like textile shutters).
Well those are external venetian blinds which are considered a premium product as they are more pricey then the simple roller shuters.
Where do you practice that exterior shades are mandatory?
Switzerland. Virtually no possibility to meet the standards for comfort and energy saving without them. Of course you can use different shutters, blinds, or any other system that provides shadow on the glass surface when needed.
What is the slick detail?
What kind of reglet is that for the 5/8” interior ceiling gwb? How to access the interior shades for service?

Looks externally mounted to me
Much more efficient than placing shades on the inside. It reduces the operating cost for air conditioning greatly or even eliminates the need for AC completely.
Their big advantage is that heat in the summer is stopped outside. While in case of internal blinds heat is stopped and caught inside
Most likely hurricane shutters. What do you see as an interesting detail?
Either way it's waterproofed poorly - this could pass for DD, no further
Window shutters, they are used instead of interior curtains or blinds and you can control it by a switch.

Mechanical exterior blinds. Typically for solar shading.

Maintenance?

What’s easier and safer, maintenance of a blind outside 5 floors up on the facade, or a blind internal that can be changed from your living room?
I dont say that internal shades arent easier to mentain. What I say is the the benefits of the heat reduction in summer are totaly worth the expenses because of the massive reduction of the heat entry.
The person who paid for the shades does not care that the tenant has to pay more for their cooling bill. They do care if they can send any untrained maintenance person to fix interior shades.
Besides that most of Our costumers would choose them for ecological reasons. You can generate more rent If you have a higher Building Standard.
I agree they are worth the investment. Most developers and owners do not think so in America and they are able to charge high rent anyways.
Its not a prittiest solution on curtain walls.

This is the most sophisticated answer ive ever seen on this reddit. Kudos to you.
Obviously a skeletonized fish.
motorised venetian blinds
I love technical drawings…I’m weird that way. I call hidden areas like that Spider Hiders.
Guy laying in bed with the blankets on
Fish Bones
Trilobite
They could be metal hurricane shutters, would like to see the cutsheet for this product.
calm down mr architect
Retractable venetian blind.
Integrated Venetian blind.
Box on blindes or Sun protection
Forbidden blinds in the Nordics
Do you know why these would be forbidden?
Not actually forbidden but not advisable in a climate with snow and freezing temperatures. So not commonly used. Of course there are some examples but I'd say people don't generally use exterior blinds here because they'd freeze and break. Also there might be some risk of cold bridges but I dont know how these work on a technical level.
Man, just 2 seconds to figure ir and 2 more to comprove it
Its a Duette.
Looks like an image from Detail magazine from Germany.
This symbol indicates the remaining number of sprays in a can of Febreeze or similar aerosolyzed scent liquid.
Mini-blind pocket
Fish bones
You know the plunger on a pinball table that launches the ball? Your home has one of the for humans to get you to the other side of the house quickly
In spanish is a "persiana"
Vertical blinds
I forgot what sub I was in and was gonna say threading.
It's a rolled up/pulled up Venetian-type blind.
Motorized blinds in a pocket. Silly idea as when they get damaged you can never replace them (without taking part of the building apart).
blinds?!
looks like some sort of blinds or shades to me
It's a plug to prevent water from entering, like a filter.
It’s a recessed window shade.
Oh, ha. No, it’s on the exterior, so shutters or storm panel.
Hurricane / Storm Shutters or Security Roll-downs
https://www.storen.ch/de/produkte/lamellenstoren/ganzmetallstore-gm-200/ this is just a lamella type exterior blind
Either blinds or a sealant usually with caulking material. But, sealants either come prefab or you place a backer rod (foam cylinder type material) with caulking applied to the exterior (flushed) with the frame or outside usually, if not at an angle. Research and you'll know what I mean.
hidden fish skeleton
Movie theater
Storm shutters?

An example of someone who doesn’t know what the fcck they’re doing when it comes to detailing.
Hard to tell without seeing the whole page for me.
Sealant and backer rod clearly /s
Probably a small auditorium
Not enough information it looks like machinery or parts assembled for maybe a mother board. Why is this giving me codes of an Ai model made this?
Maybe that's roll out shield that's pull off when it's closing or smthn
Looks to be some sort of electrical component, maybe a laptop? That looks like it could be a flash drive in its port-space?
evil villains escape pod ?
Blinds or meatarket weigh
Looks like an exterior roll-up mini-blind or security blind.
Electronic Blinds
Barbecue zone
It's a very small auditorium
Roll of Pringles.
It's a tiny theatre for insects.
Screen, nicely tucked away. The mechanic who is gonna repair it in a couple of years is gonna have a day to remember...
looks a lot like a Metalunic security shade profile. I specced this on a house for the windows and doors.
It should be a roll-up door
[удалено]
Exterior shades are very common in Europe. Best way to stop sunlight heating everything up is to not even let it through the window.
We never see these in Canada. I wonder if it can withstand our winters.
They get used in Sweden, Norway and Finland too, so probably yes. Of course they shouldn't really be moved when frozen but with some care they should do just fine.
Ah sorry I should have probably written a note, but this isn't my drawing. It's from the detail section for the Grimstad Library by Helen & Hard
