Great drawings and explanations! I agree that 1) being able to open the windows and have the prevailing winds cool the house, and 2) have the overhangs cool the house from the sun, are clearly hugely powerful and underappreciated climate control methods in construction. I agree that if something broke in an air-tight house without these features, it would just become an oven. Keep sharing, and thank you for the good work!
This is brilliant! Thank you for breaking this down. I primarily work on Passive Houses and you are absolutely right that it does not allow you to utilize local and natural materials as much. I wish that all builders and architects could watch this!
To be clear, passive house takes into consideration the local climate, sun angles and all of these things. And if your incredibly lower energy HRV stops working, you're not SooL, you open a window. And you still have an incredibly performing home. It's not one or the other. Passive House incorporates many or most passive solar concepts. Passive solar incorporating passive house concepts will perform better (even without getting certification). I don't get why some people have to treat it like a competition.
Good work. Great presentation. Starting an ecovillage in Buffalo NY. Nice to have resources like this to explain design principles to folks. Keep it up.
The video is super interesting, for a better user experience try to take the background music lower and maybe in the future invest in a better mic ;) I am sure that will help the channel growth ;)
Thank you for sharing! I love your explanations and the presentation of passive solar. It's what I want in a house but haven't been able to put my finger on.
Excellent presentation Christina, good information, clear and concise. Keep going, be consistent and RUclips will eventually reward you. Thank you, John from the UK
Great video! I've recently been trying to learn the considerations in designing a house. I think this video sums up most of the important information that needs to be considered in designing a house. Thanks for sharing.
I'm really surprised there isn't more interest in building design. Everyone lives in expensive, low-performance homes and complains bitterly about the heating and cooling costs, maintenance, poor air quality etc. My wife and I designed and built a nice, affordable, passive solar off-grid home and all the neighbors laughed. We installed an evacuated-tube water heating system too and have had free hot water for some six or seven years now. Our heating requirements are somewhere between one quarter to one fifth of theirs, and they don't laugh now!
We figured we would need a wood stove in our house, but we don't. Passive solar principles works a lot better than we expected!! Exterior insulation, thermal mass and big unglazed south facing windows works great in our area. Nice stable temperatures are wonderful, our house temperature only drops 3° F overnight. We are in a hot arid climate with temperatures ranging from 5° to 105°. We use an evaporative cooler in the summer, and leave windows open at night to bring in the cooler air. 🌞🏜️
Very interesting because I am not arhitect or constructor but i am intetestong to know the Natiral method , Eco . My father was a constructorului worker and he build in the village house ... Temperate climate zone in Romania - Europe .🎉
Excellent video and explanation!! one thing i would like to push back on the the amount of glazing. 7-11% is not at all how one should calculate how many windows. it should be how long the sun is hitting the inside of the house and how much thermal mass. and how cold it is outside. R value of window. also if it gets to hot in the house can always open windows/vents to cool it. I personally want much more than 7-11%!! but i suppose you could argue if you increase the windows you lower the insulating value to keep the heat in, but it dose not matter because the heat gets stored in the thermal mass!
Hey! Those are all important considerations. It is certainly a rule of thumb I am sharing. The density and type of thermal mass, R values of windows and walls, plus climate considerations are also important. All of the ~100% passive heated and cooled buildings historically have actually been closer to 5% and are way more efficient than passive house standards. I am currently working with a mechanical engineer on a calculator for this. Running an energy model in a program like WUFI Plus is helpful in understanding the thermal mass properties and the climate. However, we have statistics that show that 5% is sufficient for most 99% naturally conditioned homes.
Very good video. Would you consider a video on passive greenhouse. I am building one next year using an old basement wall as a back thermal mass feature. While a specific request, I bet others would be interested. Thanks.
Info is nicely presented and cover normal cases. What if you are on the north/west side of mountain/hill and facing north/west or the desired ocean view is north/west? A video on how to target passive solar while facing "the wrong way" would be helpful and very distinct vs. all the typical case videos out there.
Great idea. There is certainly a balancing act with that and trade offs will certainly have to be made. Discussing what trade-offs would be well suited does depend on the situation. I will think about something like this for the next post!
Good video, the solar calc info VERY helpful. Pro Tip (not mine / me): Set camera to look up not down. 2nd that the background music distraction, also sound volume was kind of up & down. Still 5 stars tho... LOL
Very interesting. One ghing you mentioned was having no more than 4 inches of thermal mass in a passive solar system. Would you be able to explain that please? Thank you
Great video! I am in the process of designing a passive solar hempcrete home. My designer keeps telling me not to extend the overhang of the roof because he thinks I'll want the direct sunlight into my clerestory windows during summer to bring in more light and that I can simply lower shades or invest in windows with internal shades if I end up not wanting the sunlight into my living space. As my exterior walls of the house will be 12' thick hempcrete walls, will overheating through these clerestory windows in summer not be an issue if I don't extend the roof overhang? I'd love to know your thoughts. The home has an attached sunroom on the south for isolated solar gain.
Nice! Sounds like a fun project! IMO ...Without overhangs you are at risk of overheating the space in the summer for sure. If it is a clerestory window you may be better off since heat rises, but you'll need a way for that heat to escape. You can still daylight the space significantly even with overhangs. Ideally you dont want that summer sun to hit the glazing if you are trying to achieve passive cooling, regardless of your insulation / u-value. It doesn't hurt to add an overhang, and also protects your window / wall from weathering. You can get a really efficient window, but thats probably more expensive than extending the overhang.
All homes should be built to accommodate the elderly and disabled. This will be better for everyone. Large wide doorways and hallways make using a cane, walker or wheel chair much easier. Bathrooms or wet rooms need to have flat floors and no shower hump or pan. A flat floor allows for easy access and drains need to provided. Easy to use lever door and faucet handles are easier for the elderly to grip and open. Main floors should include a master bedroom, restroom, shower, laundry and wide walk in closet with few steps to enter. Homes should be designed with aging in place in mind.
Thanks for the feedback! Its a bummer I can't go back and change these once they are uploaded. Ive upgraded in more recent videos :) Thanks for the encouragement!
Super awesome tutorial- I will be rewatching during the design phase! I am wondering if the +/- is reversed in the sun angle latitude formula? 90-43-23.5=23.5 which is winter not summer? Unless I’m mixed up? Or maybe add the angle with an arc on the sketch please for clarity?
Oh no! Did I have that reversed in the video? To clarify, the summers angle is your latitude PLUS the earths tilt and winter is MINUS. You have to make sure you do that addition / subtraction first and then subract that sum from 90 (thats why theres the parenthesis). I can send you a screen shot separately on the angles you need for your latitude. So in winter the angle is 70.5 and in summer it is 23.5. This is from a 90deg vertical line at 0 degrees. I cant seem to send a image here , but if you contact me on my website I'll send you the screen shot.
Note: this comment applies only to heating dominated climates. although it's good to design with solar orientation and heat gain in mind, it's a bit tough to say if this design strategy is primarily responsible for the durability of historical buildings. in cold climates, buildings have historically maintained their durability by 1) building out of highly moisture tolerant materials, e.g. old growth trees and solid rocks and 2) using enormous amounts of energy to dry them out (about 40 cords of wood per year for your average Colonial, or 900 million BTUs/year, compared to about 120 million BTUs/year for a New England home now) A wood stove isn't an awful source of backup heat by any means, but they aren't flawless either; woodstoves are typically associated with significantly increased health issues from asthma to cancer, and they are generally bad for neighborhood air quality. Someone asked if it'd be possible to build a small house and avoid some of these expenses, and the answer of course is yes, the smaller you build, the cheaper it gets. But in America we have a tendency to think individualistically, and building tiny is not a realistic systematic approach to solving housing issues. Families need more than 500 square feet. The average ADA compatible bathroom is 150 square feet alone. And there's no way there is enough salvageable old growth wood to solve the housing crisis using this approach anyways. I do think that keeping in mind solar design is very important to good housing design. But one of the main reasons why many of us don't live in flophouses, tenements, Hoovervilles, and house courts anymore is due to the advent of modern building materials. We aren't building with these modern materials in the best way, and this causes problems. But they're solvable problems. Trying to go back to how we built 100 years ago means that only the ultrawealthy will be able to afford housing.
Don’t forget about recycle-ability. Plastic or resin-based Insulation has to be readily separable from wallboard and studs because they must be recycled differently.
All new buildings should be designed with large roof overhangs. The large overhang provides beauty and protection from the sun, rain and wind. Protection of the doors, windows and siding make for a more durable and comfortable home.
PLEASE, do you have the ability to reedit? The music is way too loud when compared to your voice and is extremely distracting. The information sounded great but I just can't keep watching because the music is too much. Sorry.
Great video. I am looking for architectural assistance in designing a single, stand alone, rural, residential house that passively cools in a hot and humid climate. I am intrigued by under ground ventilation tunnels that incorporate evaporative cooling and a Trombe Wall to pull cooler air through the structure. Possibly a earthen roof as well. I wonder if you might point me in a direction where I might find assistance?
Hey there! What part of the world are you in? Depending on how humid the climate is - it may require a unique set of strategies. I would be happy to help explore some of the options. Reach out to me on my website! I offer free discovery calls we can talk about your project!
Good video. Just one correction though...heat pumps are for heating/cooling and are not the same as heat recovery ventilation systems (HRVS). Heat pumps aren't necessarily required for passive houses
Hi, Very informative. Can you tell me if I can design a monolithic dome (made with concrete) ton be designed as a passive solar. I plan to have the back half of the dome in a hillside covered with earth. Cooling tubes like in an earthship. Have the fromt like an earthship with a greenhouse. Please let me know what you think. Thank you
It would seem like the first consideration is which direction the front of the house is facing since to take advantage of the sun, it needs to be pointing in the right direction. If it is, then you should be able to.
@@regenerativegardeningwithpatti oh, gotcha. I didn't know where you live, but near Newport Oregon someone built a version of an earth sheltered dome home where instead of building it into the hillside, they bermed it up on multiple "sides". They had a primary "front" with big sliding door windows, and 2 other "sides", one with normal windows and the other the primary entry where cars are parked, etc. The rest was covered in soil. They had a concrete floor for absorbing heat through the primary and side areas and said they used a wood stove only occasionally. Seemed to work well for them. I'll try to remember who did the video and get back to you. Either way, good luck. This is one of the types of homes that really interests me and I wish you the best. Edit: I posted a link in a separate comment just in case they delete it. It's a Kirsten dirksen video with an earth sheltered dome home from 3 months ago- title starts with no bank would loan them money. Also, my description is a bit of, but you'll see in the video.
Have to build with historical materials if you are going to get that historical durability. This is very expensive in some places as old growth wood and solid stone are difficult to source.
cost aside, I'm unwilling to cut down old growth trees to build houses @@MemoryPallace. and salvaging old growth wood isn't a viable strategy for solving societal housing problems
I am planning to build a house in Indonesia, under Passive House Principle, the house should be airtight, however, in hot and humid regions, we need as much cross ventilation, so how should we best apply? And how do we assess wind direction on the site? Thanks
2:40 "But it's a little bit harder to heat a house than to cool a house" Come to Manaus and teach me how to cool a house cheaply. Under constant 35~40⁰C and around 70~80% humidity.
Totally, super humid climates do require a bit more dehumidification through mechanical means to enhance the the passive techniques. Likely best to use them together!
@ but I've noticed here no one has any windows in the ceiling or even near it wherever there are any traditional mud homes. Could it be because the sun is too strong here?
@@taplubambhos2869 It could be a reaction to wanting to keep light out of the buildings. Windows in the ceiling (skylights) would not be a good idea. clerestory windows with ample shading would work for letting heat escape while not allowing solar heat to hit the window and have a greenhouse effect. Another option is vents without windows, similar to a coupla. Not sure why they wouldn't, but I am not familiar with the region!
Great information and easy to understand.Thanks for sharing this. When I search for this info the results bring up passive houses NOT passive solar design as you so perfectly explained. T H A N K 🙏🏽Y O U 😊
I live in southern hemi but so close to the equator that the sun is 3/4 year in the north, and 1/4 of the year in the southern sky (although not very far)... but it is high altitude so I need the solar heat! So designing my house poses the issue of also wanting heat in the summer/rainy season (there is still sunny/hazy hours and days).. but on the other side of the house. I guess some eastern/overhead windows/skylights.. but I am afraid roof glass will let out too much heat. Anyone ever build passive-solar in this type of climate/sunlight?
This is a really good question! I am actually dealing with this myself in a design project in Kenya that is high altitude but right near the equator. I think if you use high thermal mass walls, and allow those walls to absorb sun throughout the day you can achieve some passive heating. Is it dry where you are? In this case you could have minimal overhangs. At the end of the day a back up wood stove will be used to heat the interior and masonry walls.
It's harder to heat a house than to cool a house? Clearly spoken by someone who has never experienced multiple days of 40-49degC (104-120degF) during summers when it never gets under 30degC (90F) overnight for many days. Thermal mass works adversely too; buildings, paths & roads heat up continuously for days or even weeks without discharging their heat. People in suburbia or the CBD using aircon units then cause a 'heat island' effect outside, raising the temp in built-up areas due to their machines expelling hot air from their homes like the back of a fridge, making the local area more unpleasant & causing power blackouts. Do please tell me this 'easy' way that you know, how to cool my building down - It's not like I can retrofit a roof overhang, reposition the sun or the windows or move the neighbours further away to stop the heat from radiating back from their bricks. I've already planted trees, installed insulation & ducted aircon, (which now needs upgrading), installed window tinting that supposedly filters out 90% of sunlight & 80% of heat, made blinds & block-out curtains & it's still unbearable. I'm currently cutting open the Gyprock (drywall) to stuff the walls with yet more insulation, unpicking & remaking the blinds to line the insides with mylar, & cardboard & drawing up plans for a Bris Soleil above the window & a passive cooler made out of terracotta plant pots & bamboo - but heck, if you say it's easy to cool a house, it must be.
I have not lived in those extremes for an extended period of time, you are correct. However, I have lived in tropical climates that occasionally get to those extremes. Are you in a hot and humid climate or a hot and dry climate? Dealing with humidity can be a huge factor. Also, the urban planning of your cities may be out of your control, but it seems like you are taking steps in the right direction. Living outside of a city would make a big difference. Have you seen the video on my channel about Passive Cooling? This is what I know, and Im not suggesting it is easy by any means. These are simply the passive approaches that Im suggesting that could be implemented before mechanical means if it is suitable for your region.
Thanks, Im glad it was helpful! Yes we are aware of the music issue and have revised the more current videos on my channel. This is an older video and we got a lot of feedback on that already.
Great drawings and explanations! I agree that 1) being able to open the windows and have the prevailing winds cool the house, and 2) have the overhangs cool the house from the sun, are clearly hugely powerful and underappreciated climate control methods in construction.

Also, my description is a bit of, but you'll see in the video.
Found it faster than I thought -

Hopefully this posts with the link
Thanks --- hard to hear -- probably getting a good mic will help -- :)
Working on it!
Have to build with historical materials if you are going to get that historical durability. This is very expensive in some places as old growth wood and solid stone are difficult to source.
It can’t be that bad if you build tiny. How much do you think a 500 square foot passive solar house would cost?
cost aside, I'm unwilling to cut down old growth trees to build houses @@MemoryPallace. and salvaging old growth wood isn't a viable strategy for solving societal housing problems
I am planning to build a house in Indonesia, under Passive House Principle, the house should be airtight, however, in hot and humid regions, we need as much cross ventilation, so how should we best apply? And how do we assess wind direction on the site? Thanks
Hey! I am about to put out a video on Passive Cooling! Stay tuned!!
@@christinaransbury Thank you!
The Music 😮
Alex Wade wrote several books on these topics in the 70’s or 80’s. Check them out.
2:40 "But it's a little bit harder to heat a house than to cool a house"
Come to Manaus and teach me how to cool a house cheaply. Under constant 35~40⁰C and around 70~80% humidity.
Totally, super humid climates do require a bit more dehumidification through mechanical means to enhance the the passive techniques. Likely best to use them together!
6:52 if you have good overhang then surely the 7% window rule is no more
EXCELLENT🌻 and for electric, Top it OFF...the GRIP🏭... with 🌅SOL PV+🔋 ON🌻🗽
What if you don't make any clerestory windows? I am going to make something in subtropical India
You will need windows higher up if possible to make sure the stack effect is working effectively
@ but I've noticed here no one has any windows in the ceiling or even near it wherever there are any traditional mud homes. Could it be because the sun is too strong here?
@@taplubambhos2869 It could be a reaction to wanting to keep light out of the buildings. Windows in the ceiling (skylights) would not be a good idea. clerestory windows with ample shading would work for letting heat escape while not allowing solar heat to hit the window and have a greenhouse effect. Another option is vents without windows, similar to a coupla. Not sure why they wouldn't, but I am not familiar with the region!
@@christinaransbury thank you! 🌸
Great information and easy to understand.Thanks for sharing this. When I search for this info the results bring up passive houses NOT passive solar design as you so perfectly explained. T H A N K 🙏🏽Y O U 😊
Yes!! Indeed! It is very common to conflate them
Why the need to insert music into the video, it’s annoying and distracting not to mention difficult to hear you !
I live in southern hemi but so close to the equator that the sun is 3/4 year in the north, and 1/4 of the year in the southern sky (although not very far)... but it is high altitude so I need the solar heat! So designing my house poses the issue of also wanting heat in the summer/rainy season (there is still sunny/hazy hours and days).. but on the other side of the house. I guess some eastern/overhead windows/skylights.. but I am afraid roof glass will let out too much heat. Anyone ever build passive-solar in this type of climate/sunlight?
This is a really good question! I am actually dealing with this myself in a design project in Kenya that is high altitude but right near the equator. I think if you use high thermal mass walls, and allow those walls to absorb sun throughout the day you can achieve some passive heating. Is it dry where you are? In this case you could have minimal overhangs. At the end of the day a back up wood stove will be used to heat the interior and masonry walls.
New homes should come with solar panels, a rain water collection system and an electric vehicle charger in the garage.
Indeed!
Christina is good.
The background music and mummering voice(s) are distracting. If you redo the video I’ll finish watching.
It's harder to heat a house than to cool a house? Clearly spoken by someone who has never experienced multiple days of 40-49degC (104-120degF) during summers when it never gets under 30degC (90F) overnight for many days. Thermal mass works adversely too; buildings, paths & roads heat up continuously for days or even weeks without discharging their heat. People in suburbia or the CBD using aircon units then cause a 'heat island' effect outside, raising the temp in built-up areas due to their machines expelling hot air from their homes like the back of a fridge, making the local area more unpleasant & causing power blackouts. Do please tell me this 'easy' way that you know, how to cool my building down - It's not like I can retrofit a roof overhang, reposition the sun or the windows or move the neighbours further away to stop the heat from radiating back from their bricks. I've already planted trees, installed insulation & ducted aircon, (which now needs upgrading), installed window tinting that supposedly filters out 90% of sunlight & 80% of heat, made blinds & block-out curtains & it's still unbearable. I'm currently cutting open the Gyprock (drywall) to stuff the walls with yet more insulation, unpicking & remaking the blinds to line the insides with mylar, & cardboard & drawing up plans for a Bris Soleil above the window & a passive cooler made out of terracotta plant pots & bamboo - but heck, if you say it's easy to cool a house, it must be.
I have not lived in those extremes for an extended period of time, you are correct. However, I have lived in tropical climates that occasionally get to those extremes. Are you in a hot and humid climate or a hot and dry climate? Dealing with humidity can be a huge factor. Also, the urban planning of your cities may be out of your control, but it seems like you are taking steps in the right direction. Living outside of a city would make a big difference. Have you seen the video on my channel about Passive Cooling? This is what I know, and Im not suggesting it is easy by any means. These are simply the passive approaches that Im suggesting that could be implemented before mechanical means if it is suitable for your region.

Excellent content rubbish background muzak/noise. Bye bye video hello transcript.😊
Thanks, Im glad it was helpful!
Yes we are aware of the music issue and have revised the more current videos on my channel. This is an older video and we got a lot of feedback on that already.
Are you ai generated? You're beautiful
Lol, no
@@christinaransbury 😂🫶
Less music Pls, use a microphone, and Pls speak articulatly
the background music interferes with your talking. it´s totally unnecessary
Thanks, we have revised the more current videos on my channel. This is an older one where we got a lot of feedback on that already.
