- At the University of Salford's Energy House, all the energy use is monitored and controlled, allowing researchers to experiment with all sorts of insulation and energy-saving techniques. But how to control for factors like sun, wind and rain?
The solution: put the whole house inside an environmental chamber: a building inside a building that means the weather is controlled, repeatable, and part of the science.
Thanks to all the team at the University of Salford's School of Built Environment: you can find more about them, and about the house, here: www.salford.ac....

our house
in the middle of a building
our house
Well done!
that's... MADNESS!!
I don't understand...?
madness - our house, that should explain it
Yo dawg. I herd you like houses.
0:50 So Tom said (paraphrasing) "Let there be light!" and there was light and he grinned, cheekily.
I could imagine a tired scientist working odd hours and accidentally falling asleep int he house, only for the other scientists to "haunt" him/her by randomly opening and closing doors.
Why would it scare them? They'd be asleep.

My grandpa had problems with heat escaping the house very quickly even though he insulated it pretty well. I borrowed my friend's little smartphone-mounted thermal camera and mounted it on a drone and we were able to find all spots in the roof where heat was escaping and after insulating them, my grandpa's coal usage dropped by almost 20%. It's shocking how much heat can escape through seemingly well-insulated roof. Great video!
I'm honestly surprised people still heat with coal.
@@huntsbychainsaw5986 Even though we never even need a heater here (tropical weather) when I heard that brits still used coal to heat their houses, my thoughts is just why?
We used the heat with coal. There are no gas heating mains where I live, so we had to get an oil tank installed. As this was expensive, it took a while for the installation to be done.
"Rain never falls down. It always comes sideways."
This is the most British pair of sentences ever uttered.
And it's also true.
Joule Terrace. I see watt they did there
I know, it's shocking.
Hey, that's pretty good!
Amperesting stuff!
I personally think it's re volting.
That's brilliant
A new series! I've got a few videos coming up that showcase some brilliant, but not well known, research labs. Normally I'd file them under "Amazing Places", but that doesn't quite feel right, so there's a brand new playlist and a brand new logo. I say "brand new", it's still written in Helvetica, so don't worry too much about change.
Thanks a lot!
yay! btw youre vids are the best
isn't Helvetica copyrighted by Microsoft?
Will you add the San Francisco Bay model to this playlist? (and maybe even reupload with new logo)
Names of fonts and the underlying code can be copyrighted. The look of the font cannot be, which is why there are so many clones of popular fonts. Licensing of fonts varies, and that can control what it's used for. In practice, fonts that come with operating systems and word processing programs are licensed for any use.
That gleeful look, from turning on the sun at a snap of the fingers :-)
Imagine a reality tv show with someone living inside that house without knowing it was a testing site.
That 70 year old mason wouldn't be the only person laying bricks
You'd need to do something about the windows, and the door.
Basically the Truman Show
Except they can never ever go outside. We could tell them climate change happened and now the weather changes from freezing cold to boiling hot every 30 seconds. That would be a fun show.
Let's make it happen, internet
this is all at once one of both the lowest and highest tech of houses. what a glorious dichotomy.
That is one very well dressed gentleman.
He is looking extremely dapper.
(Are we sure he's actually a scientist?)
His tie's wonky. Definitely studies something.
Big_Adam_2050 truly snazzy
You're talking about Tom, right?
@@klaxoncow He's got a PHD in lookin' fresh
I want one!
So did you have an energy efficient tea from the energy efficient kettle in the energy efficient house?
He had ice tea
IgWannA2 but iced tea is less energy efficient than hot
And also a less accomplished rapper than ice cube.
He was a more accomplished actor, though.
I'm really glad you did this video. There are many important subjects, like energy efficiency, that unfortunately quite a few simply find boring. Finding something that is widely interesting (even to those who find the overall topic a snore) can really help people think about these topics. I don't know how many people will go away and actually find some energy efficiency methods that suit their house but I'm hopeful.
Did students ever have a house party in it?
A housewarming party ^.^
Miren Summers some times they spend a week living in it, so there probably has been a party for "research" reasons
Before it was moved, there's a good chance!
Terraced house in Salford? Almost certainly.
'Rain never falls down, it always comes sideways'. Baffled.
Because of the British climate, it almost never rains on a still day, so it's almost always windy. The wind will blow the rain sideways. There are places in the world where overhead cover is adequate to keep somewhere dry. The UK isn't one of them; if it's not covered on all four sides, then the rain will blow in.
Yeah, our rain comes in on the winds.
In particularly mountainous areas the rain can go up.
We have rain that is more like a thick mist which is very easily blown around in a squall. So on hillsides the rain can follow the hillside up. I think it's found effect or similar,
this kind of stuff is why I like your channel scott. Plus, its always nice to see a experiment with such meticulous effort to control for variables.
Okay... that's odd, I thought I was subscribed to you, but when I tried to look for you in my subscription tab, I can't find you. I had to go into my history to find you and subscribe to you again... Thanks TH-cam for unsubscribing me from the channel that I like to watch...
Good you pointed that out. I was too. :(
N0616JC Productions you need to hit that bell icon in TH-cam's App to be notified to your phone. I did this years ago knowing TH-cam's algorithms would eventually descend into this kind of garbage
a house in a house! ... it's a russian doll house!...
It's a russian house!
That is some of the best wordplay I've seen. Props to you! xD
Someone really should put a dollhouse in that house, just for that proper Twilight Zone feeling.
What was different about the brick laying?
I think it was the course pattern, I'm not sure.
I'd like to know, too.
Victorian homes were solid wall construction, more modern homes have twin walls with a gap to prevent damp getting through.
Dougstillation true, but there's likely more to it than that.
Every sixth row has the bricks set with their headers [the smallest face] exposed. This is known as "common bond" or "American bond" - it's an unusual bond in a British house!
Tom, longer videos. It's ok, TH-cam wants you to make them long.
Longer videos would be more work, especially to keep the quality level the same, and that would mean fewer video's, which would be :(
Isn't the current drama around the TH-cam algorithm about the recent change that it instead prefers daily uploads over all other parameters like video length number of comments etc?
***** No its worse. It was both viewed min and return viewership.
Yeah, I'm pretty sure TH-cam's algorithm mainly focuses on daily upload views now. If you upload everyday but aren't a vlogger you'll be in the recommended section of TH-cam every day it seems.
Awww, now you got me interested in development of bricklaying techniques during the past 100 years (1:39).
Wow. Salford in a good light. Glad to see we have something
I love this channel! The awesome side of TH-cam right here !
It's amazing but I have to admit, you only make good videos. Thanks for your work!
Am I the only one that really wants to see a video on the differences in brick laying?
This is every building energetics engineer's wet dream.
I live in an 80 year old house in San Francisco - a lot of homes here are similar in age. It definitely isn't the most energy efficient but we make the best out of it. Better windows, some insulation here, etc. does wonders.
I definitely see some business opportunities for this.
tom scott found himself a new home
I don't know why, but after you closed that door behind you, I expected some sort of gag where you got locked out.
Joule Terrace - that's actually pretty funny...
Tim E I wonder, does Chris live there?
As in all jokes, there's a bit of truth in there, too--James Prescott Joule was actually born in Salford!
If I worked on this project, I would live in the house and gather subjective data; i.e. a human constantly tweaking the thermostat to react to their subjective experience of it being too hot or too cold in the house
"We have a wind machine"
Turns on fan
retrofit comes with 70's style tv. Dodgy tv presenter's. A shed load of asbestos. Stone chipping on the side. And a shifty looking 70's conservatory with Bucket loads of Subsidence. Nice. Just right for a University Student. LOL
Conservatory? On a terrace? Have you gone _quite_ barking?
Legit question why is britain full of old tiny houses that cost a million pounds?
Because Britain is relatively tiny. To put it into perspective, USA has almost exactly 5 times as many people living in it as the UK does, but it has 40 times as much land surface. Even if you remove Alaska since much of it is unpopulated, the US still has 33 times more area than the UK.
Also, up North (such as where this video was filmed) the houses are usually significantly cheaper. Generally you'll only be paying £1m for either a house in London, or a large house elsewhere.
Particularly in London, supply is low and demand is very high. And it's seen as an investment, whether you live in it or not.
It isn't. London doesn't speak for the entire country.
I'm in a flat with one decent sized bedroom and one boxier one (but still with space for a double bed, weirdly... came with the property and I've no idea how they got it in, or how I'll get it out if there's ever a need), lounge, half decent bathroom, kitchen diner, some semblance of hallway, cloakroom, utility storecupboard, garage, and access to fairly nice grounds including communal laundry drying lines... value? £105,000. A tenth of that.
If I wanted to get a one-bed studio bedsit in London, however, with no storage, garage or grounds, it'd probably be knocking on way past £500,000, maybe towards the million. The capital is in the midst of a property boom fuelled by a combination of overconcentration of jobs (leading to mass immigration both from abroad and the rest of the country, and so overpopulation), and speculation by foreign investors buying up everything they can at silly prices with the expectation they can then subdivide and charge a king's ransom in rent for what used to be a broom cupboard, or the part of a bathroom that contained the bath. And it doesn't look like it's going to stop inflating any time soon, though, who knows, perhaps Brexit might knock it on the head.
Most terraces, for what it's worth, are reasonably spacious inside. The smallest of them, the back-to-backs / 2-up-2-downs (which is what the example house also appears to be) are essentially my flat cut in half and the halves stacked vertically, which is a layout aped by a lot of so-called affordable starter homes now. Not massive, but ample space for a singleton, and perfectly good for a couple or small, young family. But a lot of them actually go back quite a long way, and it's more the frontage space that's at a premium, with the houses themselves being rather like stacked narrowboats, railway sleeper carriages or static caravans; several rooms in a row linked either directly (ground floor) or by a corridor along the side (upper floor), and some semblance of a yard or garden out the back.
Once you move up from terraces to the semi and fully detached homes, maisonettes, etc, then there's a little more room to stretch. Not quite on the scale of American homes (New York or LA apartments excepted), or some older French ones, but bigger than a lot of Mediterranean residences (like, real ones, not tourist apartments or villas) where life is lived as much outside as in.
It starts in “Tory g” and ends in “overnment”.
This was one of the best videos yet. Absolutely fascinating.
Always wondered what that energy house thing was on my campus aha, have a lecture opposite it...
Shouldn't the Bay Area model be added to this playlist as well?
A wind machine... you mean a fan?
IBM didn't use fans inside their big computers - they had ADMs (air distribution modules) - talk about calling a spade an "Earth Inverting Implement".
It's the sheer volume of air the thing can move at high RPMs. Those things generate small storms.
this seems pretty similar to NIST's Net Zero House, although that's built with modern techniques and has been used to test out various modern energy harnessing technologies etc.
I study Climate and Energy so I find this extremely interesting. Thanks for the video Tom! :)
How do you not have more subscribers? This is one of (if not the best) channels on TH-cam.
Aquatic Llamas algorithms
It's not very entertaining to children?
The picture in the thumbnail really shows you from your best side Tom
I love your videos Tom Scott :)
Wow!
Amazing vid!
Love it!
Shouldn't they have something to simulate the thermal properties of humans in the house, moving about, sweating and emitting body heat?
Good point. They could turn it into affordable student accommodation to do tests like that. Two birds with one stone.
Joule Terrace: Now with 100% more mould.
Who says they haven't? The average human only emits about 100 to 150 watts at rest or doing light indoor activities, and doesn't lose more than a half pint or so of sweat per day under normal conditions (heck, my dehumidifiers are barely pulling out that much between them right now, and the air indoors is bone dry...). A device to emulate that could be quite small and easily overlooked.
mspenrice is correct. Also, the whole point of putting this building inside another building was to be able to exactly duplicate testing conditions. Adding humans to the mix automatically nullifies that. Say one of the students has a fever one day, and is putting out 200 watts for a few hours. Say two of the students find a broom closet with no cameras, and put out 250 watts for 30 minutes...... :)
Interestingly the place I live in is in Providence, RI - it was built in 1900 so no insulation whatsoever. And when we moved in it had an ancient oil fired steam system. That was replaced by a modern hot water circulation system a few years back. And I'll tell you a $250 gas bill is better than a $900 bill per month to fill an oil tank. Now if the building owner would just blow some insulation into the walls.
"Joule Terrace" that had me smiling, well done chaps
Every single video you post has been very interesting to me. Keep up the good work Tom!
Went here a year back for a tour, walked past the place and was like "Wait a sec, i've seen this from a video"
That's pretty cool.
It looks like an SCP object. The 'Energy House' thing is surely a coverup for the true nature of this object..
Anyone got good videos about the changes in brick laying techniques?
The comment about the bricklaying challenge in this case got me wondering.
When they're simulating winter during the actual winter, then the fridge in that house is a cooled space inside a heated space inside a cooled space inside a heated space inside a cold place.
"We've got wind machines"
*Cuts to shot of large fan*
Yay Salford Uni :D
Another thing we take for granted.
I ran across your site just today and I must say your post are very interesting, right up my alley as they say, History, geography and science oddities (and those not so odd) I find fun to watch, keep up the good work, nice site.
Hi, why do we launch weather balloons if we have satellites?
Devan Velo probably because some measurements have to be done at the exact height weather balloons operate in
Devan Velo weather balloons can take measurements inside the event in question, satellites can only see it from the top.
Also, balloons are cheaper to make and to launch
Jesus Gonzalez the equipment in a satellite weighs a lot and you cant move stuff to outer orbits. When the balloon gets too high it will pop
Balloons can take pressure readings, humidity, wind speed and air temperature readings at varying altitudes, which satellites can't do.
Nothing is more gangster than making it rain for science. Good show.
Good to see people working on this. Old housing has always been a thorn in my eye. They are leaky, poorly insulated and it sucks to live in them in both the winter and summer because it's either too cold or too hot. Sure hope we get some results from this in "the real world" soon.
I can't say for the UK, but updating and improving "old" construction homes (late 1800s, early/mid 1900s) has been a thing in the US for the better part of 3 decades. You can watch episode of "This Old House" from the late 80s/early 90s and they are retrofitting old Boston (where the show originated) homes with improved windows, insulation and the lot. Granted the tech has improved since ~1990, but the intent and underlying methods have been around for a long time.
The troubles come in places like Pomona, California (where I used to live) where homes in "Historic Districts" are so overly protected, that doing reasonable upgrades (like replacing metal swing-out windows with wooden or vinyl) is illegal, because the letter of the law requires "like for like", where a metal swing out window has to be replaced with a metal swing out window. It becomes entirely impractical, because no such things are currently made, requiring custom fabrication, which is expensive, and still won't be much improved because of the materials required.
ThaTyger, Similar to perhaps half the Australian housing stock which was built before insulation became readily available. Weatherboard outside, tongue-in groove inside or something like Masonite, no insulation of any kind, multiple windows to let air in during summer - cold as charity in the cooler months.
Big up Manny
Cool Project. I hope they are monitoring the air quality inside the house. Because a lot of these energy efficiency improvement make the houses so airtight you get a build up of damp stale air. This promotes mould which is terrible for our lungs, especially us asthmatics.
Add a dehumidifier and an heat exchanger airbrick. Sorted.
It is like the room in portal that makes you feel like you are one step from the outside but it is all a lie.
You missed a perfectly good Truman Show reference vis a vis "Cue the sun".
1:48. Curiosity leads me to ask what has changed in brick laying techniques over the last century.
Now this is something i literally never heard about anywhere neither the thought of such experiment happening ever came to my mind. I appreciate your content Tom, it not only shows just the exciting things but also those that are quite unique. Have a nice day :)
careful when you say "terraced houses" so trump doesnt try to bomb it
Jack up the house and rotate it to have the majority of the windows facing the Equator, thus getting the sun back in the house, orientation is the BIGGEST thing in capturing sun energy, and its starts with planning, a house built the direction blocking naturally sunlight will ALWAYS be wrong.
Tom, scientific question from one programmer to another: Do you think a small rodent could have gotten into this contraption (intentionally or otherwise) at some point, and if so, might it have played host to a small parasite of the order Phthiraptera? Furthermore, could any phrase describing that whole situation be considered a fitting award for the next episode of Citation Needed? I need to know. For science.
Well why would you have the door opening inwards. And why would you have the door open directly into the living room.
If the door is on the inside of the frame that means the cold air / snow / rain can get through much more easily. If the door is on the outside then there's a lot more "stuff" in between and you can insulate it much more efficiently.
Another person who thinks the Japanese have it right. Presumably a Japanese person has never opened a door in somebody's face before. Not all houses have the front door there; it's not a big house.
I don't know how you manage to hit someone in the face with a door. You'd know better than to stand where a door opens. All of Scandinavia like Finland, Sweden, Norway, private homes open the door outwards without bloodied noses. Afaik this is mostly the case with all the Baltic region, Soviet houses included.
opening inwards is better for exiting and entering the house imo, unless you are carrying something that is the width of the doorway, although it may be bad for efficiency, it is more convenient
mmh. Well, this isn't a cold climate (quite the opposite in fact), but due to the presence of screen doors on most properties around here, the actual door has to open inwards.
On my property the front door opens inwards and then there's an outward opening screen door (hinged on the opposite side of the door frame) right up against it.
Still, that's not really related. XD
Most front doors I've ever seen (and I've lived in several countries, and visited many, many more), have inwards opening front doors.
Interior or exterior doors other than the main door vary enourmously, but front doors fairly consistently open inwards.
Don't ask me why (obvious things such as inclusion of screen doors aside), but that seems to be the norm in large parts of the world.
Presumably there are no streets in Scandinavia either. Or houses without front-gardens, flats (apartments) with corridors (I mean Japan has those), busy people, general need to use all the space available (Japan again!) etc...
Did they use traditional 'breathable' lime mortars, internal lime plaster to ensure it was in keeping with period soft bricks of the property? Old bricks are softer than today's modern bricks (due to lower kiln temperatures), and as a rule the mortar should always be softer than the brick.
PIR insulation boards in floors/ walls are fine in modern builds, however when introduced to heritage builds it can cause damp problems due to its none breath-ability. Sympathetic breathable solutions should be considered like lambs wool between joists of suspended floors, and lime hemp plaster for internal walls.
amazing to see how far a university would do to do their experiment.
I write this comment sitting in my terraced house in Manchester, and I will show this video to my girlfriend who attends Salford university.
Cool concept, but I question the usefulness of such a model. I would think that applying various modifications to houses in the real world, measuring any seasonally adjusted changes in metered heating and energy usage, and then feeding the data into a statistical model to identify the most cost effective and beneficial improvements would be a superior strategy.
this removes variables though, not all summers are the same temperature, people dont live in consistent ways.. plus this thing lets you simulate winter all year round. otherwise you'd have to change one thing, wait a year, then try another thing.
Someone should remind them they are forgetting about the fact humans are heat sources themselves and that activities such as electronics use and cooking can add lots of thermal energy to a system
They do handle electronics use and cooking (they mention turning appliances on and off), but they don't seem to consider body heat.
Bodies don't radiate heat very far so they might simulate it as an added effect. They don't need dolls with heaters moving on tracks.
'Joule Terrace'
No matter the research, always keep a sense of humor about it :)
Having a grad student live their to provide body heat and to run appliances might have cost more than actuators, but wear and tear would be useful data. And grad students need the housing.
1:55 A hideously expensive experiment, powered by a Raspberry Pi. :D
AMAZING SPACES, WITH TOM SCOTT
I'd watch it :) I'm gonna love this series!
That's it? I needed more information than that! Make your videos longer, please.
The important thing for me to know is... How did they improve those things?
Changing from single-pane (and double-glazed) glass to triple. Changing from storage radiators to underfloor heating (I think). Pumping insulation into the wall cavities (or putting an inch of foam between the brick wall and plasterboard finish).
Those tend to be the big ones that'll work best.
Domen Bremec Maybe reducing size of the hole between windows and wall so there is no space for owls to get in of it, just space for little birds.
ErkkiMattila
According to Neil Gaiman, wolves may also infest the walls.
Adderkleet I was under the impression that while going from single glazing to double glazing is a very large improvement, the change from double to triple is not that impressive.
Still, good insulation would be a major factor in most things...
Amongst the improvements already suggested, I would imagine replacing sash windows with casement windows would be another.
I thought Israel took punishment pretty far with the demolishing of terrorists houses. The UK takes it to a whole new level.
Tom did you look round their annachoic chamber when you where there? It's the worlds queitest room
Yo dawg, we heard you like buildings, so we put a building in your building, so you can be in a building while you're in a building.
Very interesting video, though too short as usual.
I like videos of this length, actually. They are short, sweet and to the point.
Don't you feel the need to know more?
Yeah, sure. That's why there's a link in the description for more information.
Aren't the results a bit different because it's a standalone house rather than part of a terrace? I'd have thought the next door houses would have offered a bit of insulation.
You can see at 3:03 that it's actually an end-of-terrace house. Given that there are about as many semi-detached houses as terraced houses in the UK that's probably not a bad compromise.
i'm guessing they can account for this.. terraces are very much more efficient anyway
I hope that something like this would have been used to calculate how energy efficient normal tungsten filament lamps were. Instead of just saying that only 1% of the energy goes to light. Actually measure how much less heating one needs in a house that uses those lamps. None of that was done. The whole argument of energy efficiency was done on paper and persuaded politicians to make illegal to sell them.
It's always funny to see real snow on film when you're use to fake hollywood snow.
i like thinking about the freezer in that house, which is a cold box inside a warm house inside a cold box inside a warm building inside a cold...uh...country.
Reminds me of fridges with a 'butter light', which is a small lamp to keep the butter compartment slightly warmer, in a cold box, in a warm house...
Living in the Midwest of the U.S. in a house that was built in 1888,I love seeing this,as it's a struggle making this turd more energy efficient
Double pane (or triple) windows is a great start.
Does expending this much energy actually offset the amount saved for X number of homes? I wonder what number of homes it would take for this system to achieve a return on investment.
that's excatly what he said at the end. there are litterally 6 million houses like this in the uk so finding which is the best way to improve will quickly offset the cost. plus this is a university, students need to study things and not all of them have an ROI
You came to Salford? I'm so sorry!
Is this going to be a new series, Built for Science?
So cool. It makes you happy to have science. :)
I'm a Salford graduate myself. Manufacturing Engineering, 1998 I think.
The only house guaranteed a white Christmas every year!
Why the abrupt ending?
that's really great! Any way it is publicly accessable?
What do you think....
If you went to the people that run it and show interest and beg a little you may get to see it. But I am pretty sure that its not really "publicly accessable"
