  1. The UN city in Copenhagen is also a green building. It has solar panels, and automatic external shades which help to utilize sunlight for heating or shut it out in the summer, and also insulates the building (At night all the shades close and the building becomes all white). I Don't know if it's net-zero, but it does have very small energy consumption and it's been certified by a green building committee!

  2. Late to the game on this video, but glad I found it. I am just in the midst of designing a new highly efficient and green studio as a case study for future clients and hopefully to showcase new technology to the city and it's residents. If anyone has any ideas or would like to contribute to the effort, I would love to hear from them. Cheers.

  3. Leed certification is good, but is not the most rigorous building standard. Basically as long as they are able to create enough energy to power itself. Now Passive standards requires much more than that insulating the structure as well as the interior air has to go through the house providing fresh air in all areas. As well as having large windows. Using heat pump which takes exterior temperature heat to heat their water. Everything requires triple the amount that normal houses have.

  4. So it's all good and well to try and get "net zero", what is left out of the picture is often grey energy, the energy that goes into making the materials we build with. If we don't the sustainability of the building is only posturing, because you just displace the energy you save in production of the steel, concrete and glass the building is made of.

  5. I am a lifelong environmentalist and a native of Seattle WA, where the Bullitt Foundation building is located. The Bullitt sister's were strong committed environmentalists in our community but depended on advice from others to establish the building's design.

    Mr Ferrell's video's are usually better researched. His assertion: that the environmentally aspirational Bullitt Center is a successful environmental gem – is wholly false. The list of horrible design mistakes is a long one, beginning with grossly inefficient solar panels on the roof which were chosen to tap into WA State's tax credits regardless of their very poor solar energy performance. One facilities person told me most of the "made in Washington" solar panels and inverters failed in just a few years and had not been replaced.

    I visited the building many times usually in support of local environmental political fundraisers held there. The composting toilets were infamous for bad smells and just not working as intended. The system was eventually ripped out and replaced wholesale by the building management with a more traditional design with a veneer of green design. Not that the original building toilet system was ever stained in it's initial years of operation, because the Bullitt Center was notorious in the Seattle real estate community for sky high rents, high tenant turnover, and perennially an abysmally low occupancy rate – tenant staff just did not like being in the structure. The building was poorly laid out, had faulty infrastructure even when brand new and cost much more to maintain than other commercial buildings in the area.

    In short, as a subscriber to Mr Ferrell's channel, I wish he would focus less on cranking out a set quantity of YouTube videos and turn his attention to better research even when his desired initial politically correct conclusions turn out to be misplaced. There are fine examples of LEED buildings that he overlooked. It's a shame he unintentionally perpetuated a design myths. Facts matter…. he frequently tells us.

  6. Sustainability unfortunately does not solve everything, planting a jungle close to home will attract unwanted animals and insects, and in the future there will be less space, I know how to create a world that would solve various problems such as violence, hunger, inequality and environmental problems, it would take centuries , but we would have to start now!

  7. I had to turn off this intersting session because of the high-pitched tone in the background. I find it irritating and distracting. In some of the videos it bothers me less.

  8. Net zero buildings (or rather, buildings that at least try to minimise their energy use) are an important way to reduce energy costs in a civilisation that is rapidly running into an energy crisis – where grid-based energy will increase in price. Not all buildings can convert or afford the extra cost in their construction, but these large expensive skyscrapers catering to wealthy clients (rather than, say, low-income housing) really have very little excuse. It is up to governments to enforce standards like these.

  9. We need to be mindful of the materials used, and the amount of energy consumed in the production of building materials, especially when retrofitting existing buildings. This is often overlooked.
    Also, one if the main reasons I've seen developers aren't interested in building "green", is there is no incentive, especially since so many sell the properties ASAP.

  10. it would be good to get away from large "office" or "rabbit hutch" square and dead designed "efficient" buildings and look to create efficient "down to earth" dwellings which incorporate nature as an integral part of design.. gardens, trees, flowers, animals and open space… without pavement.. hover vehicles..etc. I think we have the tech that could create this..but can we literally.."think/dream out of the box entirely?" There is much hidden fully developed tech being utilized with an agenda for "complete control" …

  11. Europe has placed sanctions on Russia. So how is Europe going to stay warm without Russian oil. Will Europe have to resort to coal, a dirty fossil fuel. It's impossible to turn on a switch and expect the world to go green. Third world countries do not have the monetary resources to construct green structures. Let's start by cleaning up the garbage on the streets of San Francisco, L.A. , St. Louis , Chicago, Paris , Mexico City….

  12. Anyone working on self sustain building? Self sufficient without interaction with outside, suffice with living in the building or do not rely on external resources.

  13. low/zero flush urinal is a very bad idea. i used to work for a company that tested zero flush urinals in a rarely used building. then they upgraded all the buildings to zero flush. entire buildings stink……. 🙂 Then i worked for a company whose building was LEADS certified. They also had to replace the zero flush urinals with regular urinals….. the LEADS certification stay …… 🙂

  14. Mycelium isnt a spore. Its a series of single celled organisms that create a root like structure that is used to gather food and water in order to produce mushrooms or other fruit bodies.

  15. Could you look into putting micro thin flakes of gold in earth orbit to cool the earth and a vacuum cleaner (no pun intended) to hoover them up when the planet has cooled… would it cool the earth or not? Would it reflect the heat from the earth too much?… of course we have Elon Musk however, as you would expect, he is hard to get hold of! Thanks… Martin

  16. Am a little late coming to this video, I've been going through your back catalogue since discovering your channel. My dad has built a few green buildings, using hay bales. The walls may be thick but does it ever make for good insulation, it is so easy to heat and cool.

  17. Back in high school, circa 1980, we had a geography teacher that was interested in energy efficient housing. Some of the criteria was related to windows, roofing, wall design and eaves, as this was single and two level dwellings. The house that scored highest was a corrugated iron exterior wall house, tin roof, wide eaves, and very small east facing windows, and only two windows we could see on the north side of the house.

    Today, I am looking to build with Compressed Stabilised Earth Bricks (CSEB) done as a solid brick house, use geothermal heating and cooling from about 3.5 metres below ground level, eaves to allow winter sun, but block the summer sun. Earth brick roofing tiles, and attempt to use battery storage from solar and vertical axis wind turbines, so the house can go off grid. With the wastewater, that should be able to be reused for toilet, and treated through an on site septic system. It will take a few years for me to get to completion, but, I will look to posting videos of the process, so viewers can have a good laugh at my expense!

  18. As it is so often, it seems one of the biggest problems is that our economic system favors the short term numbers over the long term numbers.
    The same goes for politics, as a lot of decisions can be revoked by the next government before they even have a chance to have an impact (which in turn can be the reason people voted for the change in government in the first place).

  19. i just enjoy these videos, they stay on topic and they are always so informative and even chatting about eco friendly concepts definitely helps a lot with pushing politicians on driving green projects

  20. While it's good to research new methods and new materials for construction, it is also important to also review and research the old low-tech methods of construction and materials. We should remember that vernacular buildings were made using natural materials and also used low tech and sensible architectural solutions to achieve comfort for occupants.

  21. Hello i am a pilot by profession but i want to be into construction specially with this green building concept that you shared in your video any particular course i can do to go about it or any guidance you can give me or path way to go about it would really appreciate

  22. Another great video Matt. Thanks so much for educating everybody to Green Building. We have been building green for decades and people like you are helping us make these more common and more accepted by people who are not educated in this rapidly evolving field.

  23. I expect someone a while back pointed out a technical error regarding fungus and mycelium.(time stamp 10:48 or so) Fungi are not plants, they have their own kingdom, but an in an analogy that may be appropriate, mycelium would be analogous to roots and spores to seeds. I hope a mycologist reading this will see fit to correct me if needed.

  24. There is no mechanism that would allow greenhouse gas behavior to cause global warming. Atmospheric CO2 levels of 1200 ppm about three times what they are today would greatly invigorate C3 plants the majority of plant life on earth greatly greening the planet. Global warming was officially stated at 1.1°C in 1991 and 1.06°C in 2022. The back of the United Nation's IPCC science report states it took its greenhouse gas samples at 20,000 meters altitude where it is common high school level knowledge there is no greenhouse radiant energy. This is typical practice for deceptive marketing to state legal data transparency protecting the perpetrators from fraud prosecution.

    Earth's greenhouse effect is frequently used as a primary example to high school students of a system always in saturation from the strong greenhouse gas water vapor absorbing all the greenhouse radiant energy from the earth with greenhouse gases within 20 meters of the surface that is all around us everyday and can't have its overall effect changed. There is no further greenhouse radiant energy to interact with greenhouse gases. At 1% average tropospheric water vapor over 99% of earth’s greenhouse effect is from water vapor. Water vapor would hold earth's greenhouse effect in saturation if it were the only greenhouse gas in the atmosphere.

    Arctic warming is taking place with the proving mechanism being warm Atlantic Ocean waters migrating deeper and more frequently into the Arctic Ocean warming it and the region. That warmer water is causing a few weeks less of reflective snow and ice coverage resulting in more solar heat gain to the Arctic region surface.

    0.4% of the atmosphere is CO2 and on average 1% is H20 water vapor. (1% H20)/(0.4% CO2) = 25. Water vapor is 25 times more present in the atmosphere on average than CO2. Water vapor has an CO2e of 18, 18 X 25 = 450 CO2e total for water vapor to 1 CO2e for CO2.

    The Earth’s oceans have 3-1/2 million sea floor volcanic vents warming the water and changing it’s chemistry that have not been systematically accounted for.
