Dutch greenhouse home harvests energy, food & winter heat

- When Helly Scholten was offered the opportunity to spend three years living in a home inside of a greenhouse on Rotterdam’s docklands, she immediately volunteered her family. Scholten, her partner, and two teen daughters moved into the experimental home and immediately began planting the four greenhouses surrounding and atop the home in an attempt to grow enough food to feed their family.
The experimental home, built by students at Rotterdam University’s department of Applied Sciences led by architect Arjan Karssenberg, was constructed from recycled and recyclable materials. Built on stilts it can be dismantled or moved at the end of the experiment.
In order to keep heating and cooling requirements low, inside the greenhouses the walls are coated in loam stucco to act as a heat sink: the loam traps heat from sunlight during the day and releases it during the cooler evenings.
An exterior wall is covered in plants to create a bee-friendly habitat and help regulate temperature. Water is collected in rooftop storage tanks for irrigating the gardens.
Scholten loved her time in the light-filled home, but says there are things she would improve. She would never put a greenhouse above the ground floor, because without the earth as a heat sink, they get too hot. She’d also be sure to coat the loam with a natural finish as some of it deteriorated during the family’s stay (the idea is it can easily be taken down at the experiment’s end by simply turning a hose on it).

Love the honesty here rather than defending aspects that don’t work. I learned a lot thank you!
Where would we be without Learning from our MIstakes and Experiments ?
How much insight have we gained from this project alone, and how much has it steered our imaginations ?
Fantastic is our ability to dream and take risks.
Love how she shares the bad and the good. Great case study.
Thank you for this humble and informational tour. We all learn more from what we did wrong than accidentally did right! From Northern Minnesota where we hit -45 f in winter and 100f in summer.
"Built by students" - makes the odd design more understandable, it's mostly a learning project.
More like using cheap labor in Exchange of grades.
stink...this is so cool! I am learning to disdain my western architectural education. These people you interview Kirsten are, in some ways, so much better at architecture and the Wrightian idea of form following function than many, many designers and architects I have worked with and around. Love your channel.
I think it might have helped if they took the air from the top of the top floor and pumped it under building in a network of pipes that heated up the earth under it thus heating the earth under the building and storing the heat energy for the night when it is wanted. That would stabilize the temperatures in the home and make it more comfortable.
but this is holland. logic is far to be found 7 out of 10
Bingo! That and allowing way more of the glass to open up in the summer. It should never get that hot but it's a common mistake. I built an 8x12 greenhouse of similar shape and I have huge flaps that open up at the bottom and top to allow convection to work it's magic. Like 1/4 of the roof opens up. In the hottest part of summer I take off the side walls completely. They just needed more windows that open in the right places.
She did mention not disturbing the ground though. Maybe they wouldn't have been allowed to run tubes under.
Wonderful experiment. The upper level is nice. Like an open space to watch the stars.
What stars? Do you have any idea of the level of light pollution in this city? Not to mention the clouds that gather here the whole year. And the fog? No joke.
Yes, really love this...keep pushing the envelope and what is possible.
Thank you for all your honesty,
When you talk about this house, It’s the only way for us to make design decisions ~ if we are given the good ~ Bad ~ a Never Again. Instead of everything is perfect video...
The greenhouse on the main floor would be great for an indoor pond/aquaponics system, I love these type of experiments!
I am working on that. (very small) It works quite well, its the first year running. The aquaponics system can work as a central heater and cooler depending on the temperature of the water, although It can't be to hot becouse that would damage the roots.
justgivemethetruth It would be in ground, and depending on what type of fish you use it would not be an issue I suppose. Using beneficial bacteria to turn fish waste into fertilizer is about as natural as it gets in my opinion. Plants in aquaponics don’t use as much space because the roots don’t need to search for nutrients so it would be more effective in a small space which is the goal here.
It already works in my own studio even though I did it very very simple. If you would do it on a big scale like a greenhouse that big, and use the right thermodynamic knowledge when installing it, there are awesome ways to controle temperature while growing food. There is so much to discover in aquaponics!
Daniel Douglas It is indeed fun to experiment with, and that is what this house is all about
justgivemethetruth Ofcourse it is a complex matter, I have been keeping marine fish and delicate coral for over a decade. I know a few things about maintaining pristine water quality - my reef is perfectly balanced and the last 3 years I did not have to change any water- The thing is having a nice pond to relax next to and using it to benefit the crops you grow would fit in great in this experimental house.
This is the most oner and plain explanation of a video thank you for being so openly and ones I was about to make the same mistake with the roof
Rain is what I love about Amsterdam....rainy days, good weed, pickled fish and good friends is what makes Amsterdam a cozy country.
I'm pretty sure Helly is a cool mom and teacher! Thank you.
This is an INCREDIBLE IDEA! I hope after 3 years they can move it to a community center to keep the greenhouses going to feed as many people as they can!
Her experience-based opinions of which level to cover in glass, and the real-world reality of different temperatures, are valuable resources for designers of such homes.
I learned so much from this video. It's great how these experimental housing exist so we understand nature and greenhouse effects. I want a greenhouse and what she was sharing I'll keep in mind. I really appreciate this video, very informative
Love this place ,
Seen this vid a dozen times .
Gets better each time !!!!!!!!!
👍🌹👍🌹👍🌹👍
Appreciate she explains all the struggles that come with the design
It's been a while since I've watched your videos. Wow production quality has gone up so much
Wow, what a unique experience & experiment. Her insights were quite interesting and helpful to me as I'm considering building a greenhouse attached to a house as well. Thanks for sharing this Kirsten!
I'd love to meet this women. She's so smart, articulate and filled with positive energy.
Wonderful! And she seems so resourceful! Great speaker, pleasureable tour.
In my cold climate 400 m. altitude 60 d north, I think a greenhouse on the 2nd floor over a shed would be perfect. It snows here in the first of May, no plants grow here anymore it seems. Your curse could very well be my blessing.
really neat! i really enjoy the lady explaining all the pro's and con's. and other unexpected things.. great concepts to keep in mind.
thanks for sharing! :)
I've fantasized about converting homes to this type of structure. Small bungalows would be perfect.
THIS lady was VERY helpful to me. GREAT JOB!
The host was honest about the living conditions, she was restrained in that she had alot of living challenges, she was a realist of experimental challenges, she is not the right mindset when the conditions are not ideal because she was obviously discouraged instead of encouraged to solve the engineering challenge. She provides the engineers with the goals to correct
She has the magic of a flexible mind
Ned more of that in Britain, people with their rigid minds, defensive thinking, small minded not open minded, it is stifling progress. How have we gone from the wright brothers to supersonic flight with 70 odd years and yet we still have archaic monarchies, political and economic systems, think about it, it is the deliberate stifling of human ingenuity and genius.
Very cool. I like that she knew what they were getting into and is willing to live with the imperfections. There's a lot that can be gleaned from an experimental house. All homes that exist today are built on the knowledge of the past, if the designers/builders are exposed to it. I'm not a builder, but immediately noticed a number of items that were overlooked. Some of which she mentioned. I hope to build or renovate a house and will certainly use a number of aspects of this place in my design. Thanks so much for sharing!
fascinating and so true when you think that we have that provenance of knowledge towards building design and materials such as cob strawbale brick stone and wood but not with new materials or design and when you combine them. This was a great video thanks for posting. :)
Pretty cool! As Helly suggests, some of the design and building concepts are more practical than others. This is how we learn through experimentation. It would be nice to see the other houses in the experimental village.
Fantastic sharing what is working and what can be improved
Love this space....thanks Kristen!
Current tech to add: Air to air heat exchanger, block the gap at the bottom of the structure (rubber), automatic roller shades or vertical strips acting as blinds to control heat gain, Photovoltaic panels inside the glass from the second level up (to produce electricity and block much of the light - can be offset to allow light to pass through) and many more ideas.
PV cells inside would heat the upper floors even more than they already are.
They could retrofit an earth battery, pump all the hot air 5m into the soil (and they wouldn't have to wear coats "outside" to cook during the winter).
~9:30 you can have a greenhouse up top but you also need sufficient thermal mass in the floor to stop the heat getting through to the rest of the house and sufficient potential airflow control in the greenhouse to be able to keep the temp in the greenhouse where you want it. just like an earthship ground heat/cooling pipes can bring the air in through those cooler soils and bring it around the house with the aid of the heat (hot air rises) of the greenhouse and ducted vents throughout
Kristen you are doing great job ...thank you ...love from shimla (india) ❤️❤️❤️❤️🙏🙏🙏🙏🙏
I just love this channel
Muchas Gracias x compartir. Great practical eco sustentable real experienses data for our coming generations.......awesome film by Kirsten.......
I designed a good compromise between this house and a standard building nice to know I am on the right track and this video answered some if the questions I had, Very doable. The heat on the top floor is actually easy to deal with.
Basically too much glass. Even for a greenhouse. I am using about half the glass and still building three stories. Using earth tubes to regulate the temperature at the top.
Мне очень понравилось. Считаю такое решение гениальным ходом. Уважаю людей, стремящихся к гармонии с природой.
YAY the tiny houses, excellent experiment, hope it carries on to more permanent dwellings
I was thinking about some of the tiny houses while watching the movie, "Ready Player One". I'm sure the art director was just trying to represent really cheesy urban housing when showing "the stacks", but it reminded me of some of the videos I've seen where they planned to stack modular homes in racks several stories high. Not sure if that was one of Kirsten's videos.
very well explained thank you very much for all the inputs :) !
The form of the structure is really quite attractive
Gah,fabulous!! Like the host expressed, a few modifications (engineers utilizing technology for automated humidity, circulation, et al) and this house is wonderful. Thanks kirsten!!
That's what I was thinking while watching, that all the problems should be solvable. But they did place a major restriction on themselves that all materials had to be reusable; she said they could not even use tile in the bath because it would leave behind some rubble. I suspect they had restrictions on energy use, too. But a waterproof membrane here, a glass wall there, a vent, a fan, and so forth should have made it possible to vent excess heat and grow the crops they intended to grow. They really should have consulted experts more on the greenhouse, and problems like "Second floor 30 degrees too warm" should have been great classroom exercises. I'd really like to know what was going on in the academic institution -- was this built on a shoestring budget? Electrical problems in the kitchen not solved. Did the professor lose his funding? Did he alienate other faculty? What got in the way of thorough re-engineering after each season to address problems with new solutions?
condew yes, classroom/budget factors would be good to know. I didn't catch the bathroom tile comment. If the house provided enough privacy, one could just shower in the garden on a wood base, surrounded by plants.
The top floor garden should have been more than enough space to provide food for the family, especially with intensive methods and air circulation, double walled glazing, etc. The second floor could have easily used a growing vertical space for food; convenient, accessible, et al. Ahhh the list goes on.
I did like the loam idea though tamped earth walls seem to hold up better. I'd love to see a video of the construction in progress.
Really bad gardening. Environment in green house has to be regulated to host plants. There is no point in all this suffering if not growing lots of plants.
The garden needs to be on the lowest level, as heat rises.
@@sapphireblue222 The top level would be great for tropical fruit trees.
I can't really understand why the plants suffered from the air ventilation on the ground floor / courtyard. Typically a grape vine works best when its roots are outside the green house, but grows better and fruits with the vine inside the house. If the amount of throughput of air was that great, surely a loose filtered barrier would reduce the throughput band drying of the air over the plants in its direct path. Also additionally a horizontal awning at first floor level would act as a baffle and push air towards the kitchen floor to provide air turbulence to help move the stationary air upwards.
A cavity wall system adds some insulation. If the outside brick is swapped for glass, you have a repellant layer, and reduce the needed material on the inside. Plus you have some cavity, without such an extreme switch of temperature. In the winter anyway. The summer would be a challenge. Housing that takes advantage of the winter sun, can use large awnings that shadow when the sun is high, but you can still take in low winter sun. Or you can use diciduous trees for summer shade. Other tricks can be bouncing light/sun in via ponds during the winter. We had a south facing house (in the UK) and it seemed ideally suited for a conservatory, but summer would have been tough - without measures. It would have been incredibly welcome in the winter. The house was detached and had dual brick skin with a cavity. It was really cold and horrible however much heat you blasted at it.
That is one of the most useful videos I've ever seen. Much useful information..
Passive solar design or just as an addition to an already existing sun porch is a great idea n worth the investment in so many ways. I did this with the house I bought just by extending it out 7' from the 6' it already was.....enclosed in with slider double glass doors and large skylights above (the ceiling is vaulted)....voila. You have daily heating (provided the sun's out.....) and a great place to spend the winter. Add plants you desire and it really takes the 'sting' out of winter, not to mention how it helps your psyche!!
If you had glass screens separating the levels you could force the air to move through the building.
Great. Interesting and mostly because you are also telling about the downsides. Cool!
watching this again is helpful now that I'm planning to build a tiny house with a green house.
I would love to be part of an experiment like this. A wonderful program for sure! Thanks for all your work.
Genius! And all the ideas for improvement!
to fix their water collection leaking problems have the barrels up on the north edges of the grow beds so when it leaks, it leaks onto the plants.
i like how the dog has his preferred spots all over the house
Very educational. Thank you very much.
As for air circulation on over heated second story patio deck with no air movement. There needs to be steel grate or if wood is desired, needs to be 2"x2"s with gaps in between.
Or simply router the existing deck with some kind of really awesome creative art design that will create an awsome pattern on the lower floor walls as the sun rays penatrate thru the design like yays of sunshine thru clouds. Your welcome.
I love this concept. Perhaps citrus on the higher elevation? Aling with the figs? I think a bit of experimentation with the right plant in the correct place might be an idea. Automatic watering would also be on my list. Thank you for this xxx
I love this home! I wish someone in usa would do this and I move my family in...permanently lol
that was perfect💙
Design and Build events are always pretty damned fun! :D
🌈Wow your house is really, really amazing!!! 😍😍😍
I'm building a mini tiny house with tufflex and this video helps
Some excellent info, thanks!
Concern:
. Get a fire sprinkler system for the wooden house. That greenhouse would fill up with smoke like crazy if the place caught fire.
Beautiful job and amazing idea though. I've been curious about these techniques for a while.
I really like that Gelandewagen of yours!
They're lacking thermal mass hence the cold in the winter months, solar heat has nothing to be stored in so it just fades. Other than that pretty cool implementation really. Thumbs up, keep 'em coming.
For bottom, I think air could be diverted up so as to let ground plants alone. If different floors were separated then they could heat up individually, could be a conduit for different times of year
❤ this build.
How much did they spend to learn that glass box get hot in the sun and hot air Rises
Yes but she said they mostly never see the sun.
@@jeffk464 indeed, it is in holland so it is a news-item if there is sunny weather (no joke)
This is incredible!!!
Right it's the difference between play and work! BUT you do your best most creative work when you are playing or playful
That house is awesome. Almost like the house in the Stockholm area in Sweden. Greetings from Andreas on Off Grid Sweden
The Swedish home is way better.
thats awesome. i would add ankled wooden boards on the outside that shade the greenhouse in the high summer sun and let through the flat sunbeams in winter. dont change the 3 levels! but maybe use an aqarium-cleaner connected to a floor robot to clean :D
The upper floor wouldn't be so hot if you could open the part of the roof, and let the heat to go out. i watched a video , people build green house over their house but they had the roof with a part of it what opens and closed . good video. Thanks for posting.
Please paint all upper levers white. Best would be an aluminum tinted paint, used primarily for manufactured houses. You need to increase the albedo to help reflect the solar input of the sun. You would see a remarkable decrease in the heat gain, just by painting the floor and planter boxes white. It's why the polar caps stay so cold in the summer months. The increase of the outgoing solar radiation.
As for the sand parge on the wall surfaces. Try a Swedish water borne flooring finish. It durable, eco-friendly and water resistant.
Great job and brava for the undertaking on your part.
Great experiment, I really enjoyed learning what worked and what didn't. I'd be interested to know the rough cost to build the structure in it's entirety?
Wondering same. Has to hundreds of thousands
oh my goodness. This is an absolute dream.
The high pitch at end of each sentence is impossibly abrasive.
Plant some shade trees around the outside for the privacy & also as a windbreak, & to control the sunlight in that room. Plant fruit trees around the yard. & use that rubber in the hottest part of the day to control the excessive heat.
Do we know if there is an updated version of this home now? also, im wondering why if they ever considered double laeyering all the windows to create the same insulation effect as the main rooms.
I like that decoration of rope & plant vines over the dinner party; i wonder if they could make a false ceiling of criss-cross vines if they used enough rope.
I am astonished that the architect that headed that project did not figure out that there was WAY too much glass. Even in the Netherlands. I lived in an apartment with a loggia that had been retrofitted and got large glass windows facing south (not the ceiling which is the worst source of heat).
In winter when it was not bitterly cold I could turn off the heat at noon. And the other very obvious thing, is that airflow is important. That is no new challenge and someone did not do their homework on other projects (from the 1990s, 2000, mind you). That challenge is not new either.
I could have told them they were getting into trouble with that much glass. It is a pity because all the resources could have gone into designs that would be really experimental - as opposed to need technology fixes, are expensive.
That was an own goal (of the leaders of the project, not the students no the testers).
It is urban environment and it is like they lived on display, I would not like to be in the glass house all the time.
lead your chimny smoke through a large organic compost, solves your problem with ash going through the plastic plus cleans the smoke, we did it in Denmark with success
This was great.
“We need to do it a lot more” - yes definitely we need to keep trying but... Need to study materials little better. Hempcrete stop wasting time, use what works. 👍 shame a lot of good engineers and designers in Holland. Seems like old governors program the upside down. Temporary every 400 hrs. Thanks for sharing. Amazing 3 year experiment. Much strength.
Yes thank you Helly for doing what you did. You were able to give answers to questions that they didn't have real life experience for. Many of what said made sense and she knows because she has lived it. Thanks Kirsten.
awesome video, i always enjoy your channel!
A giant white roller shade on the outside would be great, reflect the sun on hot day, could be installed on the top of the glass, and roll down the roof.
Could roll much like a dump truck covers its bed.
Wonderful!
I'm from the region around Rotterdam and had NEVER heard about this house! Very interesting to see!!
Ainiewainy same!
Sadly I don't think you can see more than the outside of the house, seeing as it a residence!
The Dutch house doesn't seem very private, but other than that it seems a magnificent way to live.
Now I want to visit this house.
omg! so many windows to clean!!!! :O
So the air flow issue could easily be fixed with that design. You would have to add in a vertical tube that had hatches that opened at different heights to allow airflow to different areas. Or add a resistance barier to disrupt the bad airflow and help redirect it.
Good that she's honest about everything. The opposite of architects, who are eternally self promoting. Salesmen posing as designers
Thanks for sharing! Wat een prachtig project! Misschien ook eentje voor de tropen?
Inspirational! I think I'll consider to build one soon I have the resources.
Wow wow wow wow wOw. This is fantastic.
There is so much more that one can do with such a set-up that would be better. The lowest level in the front would support a few dwarf fruit trees if it was redesigned. There is a lot of wasted space in the design, and not just spaciousness.
The house needs to allow for air circulation and ventilation that works for instead of against. Include aquaponics. Have water storage housed over plants or aquaponics, with sufficient overflow directed properly as well, so that leaks aren't a problem. Have some area that is not greenhouse roofed, and just very well insulated. Have the ability to shut some area off from others at the appropriate times.
