These are all free. It's incredible how many modern-day designers and builders do not consider passive solar design and build principles. Thank you for spreading the word.
I designed and build a solar efficient home almost forty years ago using many of the techniques discussed in this video and they work just fine. I am in Perth, Western Australia where it can get very hot in the summer (40+ degrees C, 104 F), but even without any mechanical air conditioning the house remains cool in the summer and warm in the winter, with very little in the way of mechanical heating or cooling. The thing to consider carefully is adequate insulation all around, and avoiding thermal bridging that will allow heat to pass from the exterior to the interior of the building, or the other way around. I did at first have some issues with this which once identified needed to be retrofitted. Also, if you use thermal mass in the building such as clay bricks, understand that it will take some time (possibly years) for all of the residual heat stored within the fired bricks to escape and the bricks to cool completely, but once this has happened then the thermal mass works just fine. I have observed that over the years we have saved significant amounts of money by not needing to install, operate, maintain, and eventually replace mechanical heating or cooling systems.
Thats amazing to hear! Do you have a video on your building? For sure, important factors of insulation and thermal bridging. Interesting point about the fired bricks... I had not thought of that! Yes! It is 100% possible to heat and cool a building with virtually no reliance on mechanical heating or cooling. It is a very resilient solution!
This is a great video,simple explanation of every natural cooling technique,great diagrams of each posible method,I did the cross ventilation design in my house and it works like a charm ,thanks a lot !
Nevermind the naysayers and those who seem to think their criticism is warranted. This video was very well put together, and diagrams and design sketches usually give much more detail than actual pictures of existing structure. If your viewers call for real life examples, you can always put together a video or series of videos featuring that, but those examples don't HAVE to be included in an instructional video like this. As for criticism regarding your filming and framing, let your video editor worry about that, if you have one, and if you do it yourself, don't take just random advice from random internet strangers. Your video editing looks great.
Blindly criticizing someone makes you a jerk, but blatantly lying and brushing off clear faults is equally bad. Pretending everything is perfect helps no one, least of all the creator, who might genuinely want to improve. Constructive feedback, even when critical, is far more valuable than empty praise. Dismissing valid observations as 'random advice from strangers' not only disrespects those who take time to offer input but also undermines the creator's growth. Encouragement is great, but it should never come at the expense of honesty and meaningful improvement.
This is the first video I come across that explain the dynamics of passive cooling of a structure. Thank you! Many videos address the A/C systems and “close envelope” of the structure, but the content of your video is very interesting!
This is a great start for people who would want to dabble around with the mentioned techniques, thanks for the pointers! p.s. I'm not sure why people in the comments are criticizing the camera position as well as voice overs, I think they are well-done and well-edited, keep it up!
Fascinating how traditional architecture took into consideration all of these passive cooling methods. Our traditional home style in South India called Naalukettu, has really low overhangs for shading and making sure only the cooler denser air flows inside and it flows into an open central courtyard from where the warm air rises. That open courtyard also recieved all the rainwater with the roof sloping into to the central courtyard and had the water flow out with drain pipes under the homes and into a pond beside the home.
I love this! So true, traditional architects thought these factors out a lot better! The central courtyard serving multiple functions, with the beauty element im sure!. With modern technology, its sad to see that so many designers have gotten lazy with these techniques.
I'm just here to appreciate your channel and videos. Thank you for all you do and for making your knowledge available for free to anyone. I'll be building my own house in the foreseeable future and I'll try to make it a passive solar house. I never knew this term, I just called the principles architectural thermo-efficiency.
Aw thank you so much! Yes, I want as much information as possible to be free! Thats so great you will build this way, we need more people doing the same. I like the "thermo-efficiency" term though, I might consider that!
I like your content, but I like to point at the sun having the highest power at noon (the sun's highest point) which in the northern hemisphere is south. When hitting glas, the light is "converted" to heat. Preventing the most powerful light to fall through glass will have the highest impact. The highest temperatures though are in late afternoon as it takes time for everything to heat up. When you are not in a region with heavy or frequent rain, it makes more sense to have outside window blinds like the ones you see in Spain or Italy than any kind of roof. You have a light and bright room when you want it (winter) and can keep the sun outside when you need to.
Christina this video is awesome. The information you share is EXACTLY what I have been searching for, with little success. I have subscribed and already shared many of your videos. T H A N K 🙏🏽 Y O U You are a star!! 🌟
Some excellent tips. The download is also very useful. A couple of thoughts: 1. Low E glazing is the first step; I suggest double or triple glazing where possible as well, because it is not only direct solar exposure that heats the window, but convective heating through the atmosphere. 2. When shading windows, be aware that the shade device should be wider than the window to cut the sun exposure at lower sun elevation angles; heat can be gained from pre-mid morning to later afternoon in hot climates. 3. An exterior wall layering from inside to outside can be helpful: brick/masonary-insulation-airgap-thin cladding that will keep direct sun off the inner massive wall structure. This keeps the inner thermal mass cooler. 4. Concrete slab-on-ground, with edge and perimeter insulation (polystyrene is good) for about 3 feet or so will enable the slab to stay close to deep-earth coolness. 5. In really hot climates, a 'shade roof' can be helpful this is a ventilated roof as a shade or 'umbrella' over the weather roof. Of course the roof system needs to be insulated at about R4 level. 6. Carbon worries are irrelevant. More CO2, better plant growth for local vegetative cooling.
Your first 5 points are quite good and relevant. However, more CO2 in the atmosphere is not good for plants as it interferes with nutrient uptake and carbon sequestration, and for food crops makes them less nutriious.More C)2 also sets up a negative feedback loops causing a doom spiral.
Well done, girl. 🎉This is exactly what we need to resort to - nature. Nature has treasures of comfort and solutions to our excesses. All we need is wake up to it. Let me congratulate you for showcasing a noble novelty we have distanced from over the years in search of comfort and returning to it for the same. Christina you are marketting gifts of nature and I love the very idea. I love countryside living and have been enjoying many of the nature's gifts most of my life. I am planning to build a granpa house using gifts of nature, no electric lighting during day. Cooling without ac, potable water from humid air, a slide with each stair, worm holes between floors for kid adventure, a diy family workshop. A rugged but safe lift between floors (when my knees back out on me)😂, and so on it goes. Imagination, imagination, imagination!!! Christina, I am 70. Will you help me design my house. You will be my guest in Pakistan when complete and I will take you around to Gilgit, Kashmir & to stunning beauty of further north. So, what do you say, nature lover? I am a mechanical engineer with hydropower as lifetime profession. Your presentation was substantial with simple science, I have subscribed your channel to remain in touch.
Great introduction presented. First thought should be for proper siting and orientation to take advantance of passive solar components and prevailing wind direction. It would be helpful to illustrate the various centuries old traditional solutions developed around the world to achieve all these benefits plus the aesthetic components that it provides mental health such as green plants and more natural curved lines🏆
I'm designing for a tight house but also for passive ventilation with my fans, window types and placements. For those nice sping and fall days where I don't need to run my hvac and dehum.
I have a louvre window at top of stairs and open my tiled laundry door and you can feel the cool air coming in the hallway from the laundry and wafting up the stairs void as the hot air goes out the top of stairs window.
Hai there! Thank you for sharing. May I ask something? In the Stack Effect, shouldn't the opening at the bottom (lower temperature) be smaller than the opening at the top (higher temperature) to maximize airflow?
Generally speaking they need to be similar sizes so that the air intake is balanced with the air exhaust. However, if you live in a colder climate, you make need bigger openings at the top to effectively move the air.
I used these methods in my house, I live in a hot climate and the "normal" way of building, attracts and traps heat, now black and no eaves has become a design trend its even worse...Thank you for your excellant vidio..
Humidity is tricky, I have not come across a passive / natural way to do this yet. Thus my disclaimer in the beginning of the video. Mechanical means may be necessary for dehumidification.
Yes! That is another method that can also be used for passive heating and storing heat since water is such a great thermal battery. Im hesitant to put water on roofs in my projects (just from a water proofing standpoint). How is it currently performing after all these years?
This is really good. I'm going to be building a house in the philippines, could you please do a video on how to reduce energy consumption in a hot and humid climate? Thank you.
Usually people think insulation is for cold climat only. But it actually works in hot climate, too. It reduces heat (or cool) "travel" in both directions. You would need less ernergy to keep a room or building cool. However, solar panels may reduce your costs on the mid-term run, too. After 20 years they usually still have 80% of their initial performance.
@leonlowenstadter9223 to anyone who knows this better than I do, my question is this. If we're in the Philippines for the ambient temperature during the summer is 90, and I'm comfortable with my house at 80 with ceiling fans, that's only 10° difference. If I'm in the north where it's 0 outside, and I want my house at 68°, that's 68° that I have to keep out. With only a 10° difference between outside and inside temperature, the insulation requirements have to be a lot different. I'm wondering if I should spend money on solar panels and air conditioning versus insulating the walls and ceiling and getting double or triple pane glass?
@johnb5478 Honestly, I am not an expert but I taught myself a lot about it. However, the insulation would make most sense on walls to the south so that less heat passes the wall. Insulation on the ceiling or the floor are more for cold climates as you like to keep the heat from exiting upwards or the cold "draining" heat from below the building. Replacing the windows is far more expensive than insulation, so this is usually a bit further down the road. However, insulation needs to be thought in combination with your high humidity (mold). On the other hand, compared to solar panels and A/C it's no maintenance. As you probably have many sunny days A/C with solar panels probably makes most sense as A/C reduces humidity, too.
@leonlowenstadter9223 thank you for the reply. I had considered getting a whole house dehumidifier, but I don't know why I wasn't remembering that AC also removes humidity. I appreciate you reminding me of that and we will stick as much money as we can into keeping the sun off the walls and windows and get some panels and mini splits where we need them. Thanks again.
The ceiling cooling tubes as a radiant cooling system is a fantastic idea..!!! I've never thought of it. (or heard of it) Thank you..!!! I'm suscribing.!!
I wonder what you have to say for heating. I live in Europe and we don't usually have AC despite temperatures may go from -20°C to +42°C. Thus, it can get unbearable in summer, especially because of heat getting trapped inside. On the other hand, we still need to heat a lot in winter and the energy goes literally straight out of the window the moment we want fresh air! Plus, we have simultaneously too dry indoor air in most places (irritated noses and eyes) and still a mold problem in bath, kitchen and basement, and any place where cold and warm rooms share a wall...
Hey! Yes I will be doing a video on heating here soon. It sounds like there is not enough insulation and lack of balanced ventilation. Its still important to have mechanical ventilation in cold climates to filter incoming air on days you don't want to use passive ventilation / open a window. This will also evenly distribute internal humidity throughout the spaces. I would insulate between warm and cold rooms, as there where be condensation on any surface if the delta between the temperature is too much. Hope that helps!
@christinaransbury Thanks. Two of three apartments I've been to have no window in the bathroom and both bath and kitchen have electric ventilation, but in many cases, it seems woefully inadequate.
it depends on the humidity levels. Passive Cooling techniques are like "preventative" care... they should be implemented prior to mechanical means. Some climates require mechanical cooling, but should be minimized as much as possible with passive techniques before hand.
suggestions: camera position is too low, move it up and stop moving your chin up. Plus it might be a good idea to do some vocal warm ups prior, you're voice is a bit too nasal sounding.

Humidity is tricky, I have not come across a passive / natural way to do this yet. Thus my disclaimer in the beginning of the video. Mechanical means may be necessary for dehumidification.
I'm totally into all this! I live by an experimental house from back in the 70's that used a pool of water on the roof!
Was it still? Sounds like a mosquito breeding factory
Yes! That is another method that can also be used for passive heating and storing heat since water is such a great thermal battery. Im hesitant to put water on roofs in my projects (just from a water proofing standpoint). How is it currently performing after all these years?

On climate ready homes? or on Kerala India?
Having lived in tropical places, mostly people sweat their brains out unless they have air conditioning and never go outside.
Right, humidity is a whole other animal!
yes, doesn;t work in all states or countries, too humid is too humid outside, 26 years in hvac and humidity business
In our region the air is too hot outside. So I think passive cooling rolls can't work here. Am l right?
