My off-grid log house here in Finland is already net zero. Locally sourced logs for building, triple pane argon filled windows, heating on wood (renewable and sustainable) and power from solar with a back-up generator running on vegetable oil to get through winter when we don't have sun for the 10kW solar array. The generator only needs to run to recharge the batteries instead of running 24/7 to keep the house going, making the whole thing more efficient.

In North America the greater gains are to be had from moving away from sprawling car dependent suburbs. LEED gold towers are great but I think it pales in comparison to the gains to be had from simple residential zoning changes.

[@sebastiant5695]

commuting to and from the net-zero building is a potential waste of energy. Location is another important factor then the building. You can have a inefficient building a location where everybody walks - is better then a net-zero building in the middle of nowhere - where everybody takes a car.

Thanks, Matt for publishing the video! As an architect and multi-discipline engineer, I have been for decades trying to educate clients to incorporate these technologies.

Of course, our planners and developers only thinking about quick money making and putting it into their pockets. Back in 2012, I suggested to use that water collection off the roofs in every residential Kitchen extension & Loft Conversion in London. Do you think everyone was very much interested? Of course not. They looked at me as on idiot trying to complicate things. Even now in 2022, basically we have only one Siemens building like that, actually collecting water from rain. OK, maybe 2-3 buildings. But that's a drop in the ocean for the last 20 years. We should start think differently how to change the system. The system has to change as well. Leo(Architect & Engineer)

I don’t prescribe that we give up trying to improve our buildings through improved materials and design and object to the inelegant over use of mechanical and electrical systems that I feel would be better solved with passive design which would use less energy and provide more comfort by reducing drafts and injury.

The benefit that you neglected to mention from the mycelial bricks is that concrete production produces a huge amount of carbon dioxide which would be reduced. By using the corn stalks in the building you mentioned, that building essentially also sequestered all the carbon from those plants instead of putting it back into the carbon cycle (until they broke it down for the biodegradability demo). This could provide the opportunity to build buildings with a SIGNIFICANTLY reduced carbon footprint or even a net negative one all the way back to the base resources.

We have a "low flow" crapper. Usually we have to flush it _AT LEAST_ 3 times to get solids to go down the drain. And yes, I've had the rest of the plumbing checked, no blockages in the drain lines at all. If I was going to replace it with another low flow I'd look into a system designed for marine or RV use since for those you REALLY don't want any extra liquid than is absolutely necessary going into your holding tank (or sewer system).

[@Wookey.]

It's 'Bree-am'. But I'd disagree that LEED and BREEAM are 'the most rigorous standards for sustainable design'. (3:53) Passivehouse is s great deal more rigorous. Breeam and LEED both let you trade off actual building fabric efficiency against bike parking, and bus stops and nearby shops. All of which are good, and sensible aspects of _planning_, but rigorous building standards should be about the actual building, both energy use and embodied emissions.

I think there are some good ideas, mixed in with lots of pretty poorly thought out ones. My home was built using a new shingle made to decompose faster in the landfill. Turns out it decomposed on my roof causing water leakage and damage after 10 short years. And the builder installed these exterior lights designed to ONLY allow CFL to be used by using a non-standard base for the bulb - that were no longer made when I went to replace the bulbs. So the landfill now also has 4 light fixtures in it that were obsolete. Make a note to do another show in 5 years about what worked and what didn’t.

[@bobgriffin316]

I own 2 Victorian properties that I rent out in the UK. The flat had mould problems on the walls that I could not get rid of. I double glazed the windows. It didn't fix the problem. I insulatated a solid brick wall that didn't have windows on it. I insulated it from the inside. The mould stopped happening on that wall only. I could not insulate the two bay windows because I had already doubleglazed them. The insulation would protrude beyond the double glazing sills and framing so it would look a total mess. The rooms were also very small. I then found that there was plasterboard in Wickes Builders Merchants (in the UK) that had 9mm of plasterboard stuck to 17mm of insulation. I had old plaster that was 32mm thick. I removed the old plaster and had this plasterboard put onto the wall. It ended up exactly the same thickness as the old plaster. It fitted perfectly with the double glazed sills and frames so I didn't need to mess with the double glazing. This fixed the mould problem completely. It also reduced the amount of heat going through the walls by 50%. I haven't had a problem since I did it about five years ago. Under the floor is so cold now that it is hostile to mice so it discouraged mice from living under the floor. They lived near the hot pipes of the central heating near the boiler judging by the droppings. I guess that he mould might have been on the walls because the property needed pointing. If the pointing is bad then the rain soaks into the walls. When the wall dries out after the rain it acts like a fridge and the wall gets cold. You then get condensation on the wall because it is colder than normal. I pointed the walls. However, It takes about 1 year for every inch thickness of the wall to completely dry out. So it would take about 9 years to dry out fully. So the mould problem continued. I also insulated under the floorboards with solid insulation between joists. The solid insulation was held up with thick chicken wire nailed under the joists. The solid insulation meant that if water was spilt on the floorboards then the joists will get not get permanently soaked. If fibreglass was used then the joists would become permantly wet and rotif the fibreglass became wet. While I insulated under the floor I insulated the central heating pipework with Bylaw 30 insulation which is twice as thick as the normal pipe insulation. This saves about 1KW of heat when the central heating is working. Insulating the pipes is more important than insulatiing the floor. 1KW is about 20% of the heat of the whole flat. I insulated the cold water pipe as well so that it would not freeze and break. I then changed the draughty front and back doors and installed double glazed doors. They obviously stopped the draughts. They also were air tight so they didn't let mice in. I don't have mice in the flat anymore. It was a permanent problem before. I changed the boiler to a condensing boiler that is over 90% efficient when my old boiler became uneconomic to fix. That saved about 12% of the heating bill. My boiler is getting used less often so it is going to last longer and need less maintenace. I did similar things to my other property. I got the double glazing done by a cheaper company and the quality of the work was about the same as the expensive company. In some ways it was better and in some ways worse. I didn't have a mould problem on this property. That property is a house so I had a roof on it. I put solar panels on the roof. I did this while the government was paying me for the electricity that it produces for the next 20 years. It will take me 20 years to get my money back for the solar panels. But my tenants also get half price electricity as well. If you add the two together (the tenants and me) then it takes about 10 years to get our money back. I put 4KW peak of solar panels on the roof. That is enough to cover all the electricity needs of the house over the year. 50% of the electricity from the panels is used by the tenants. The other 50% is sent back into the grid because it is producing too much for the needs of the tenants at the time. The value of the property will go up in value as well. My tenants don't want to leave now because the properties are so comfortable and cheap to live in. At the beginning of this my tenants in the flat were always complaining and getting me into trouble with the the local Council to fix the mould etc. I tried to do this. I didn't know how to fix these problems at the beginning. As time went on I found more solutions until I completely fixed all the problems. I did these jobs in small projects over 15 years. It was financially hard for those years as I spent the money on these solutions. I write all this because it might inspire you to do something similar. Even if you are a renter it is good for you to know how mould can be fixed so you might want to talk about solutions with your landlord or estate agent. He might want to fix the problems and have an easy life. My estate agent charges me less because he knows he is getting less hassle looking after the properties. It is not always about making the most money from the tenants. I accept that for many landlords it is all about making the most money possible so they won't want to spend the money. I am enthusiastic about reducing energy in buildings. I would like to see a greener world. I have studied about this subject. Other people are not interested. Also, for some people it is too daunting a task to take on. If you as a renter gently pass this information on to your landlord who is ameanable to all this it might be less daunting for him or her. Best wishes.

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!

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.

I recently participated in the review of a building design and the builders explained that solar panels were not being installed because they wouldn't be profitable.

[@blackmadra]

I used to work for one of the software providers you mentioned early in the video. After many years of working on LEED buildings I have come to the conclusion that LEED is a scam. It is simply a money making scheme that allows building owners to pretend that they care about the environment. As a building designer/energy analyst there are so many loopholes you can exploit to get your building a higher rating. In the mid 2010's The US Green Building Council outsourced the review of LEED submission to India which resulted in an even lower quality of scrutiny than before. I worked on a number of high profile office buildings, industrial plants and data centers in the US, EU and Middle East. USGBC are only interested in making money.

Interesting video. In the UK Breeam is said both ways but mainly Bree Am. The point you didn’t raise is that most large office or other commercial buildings are constructed by a developer / pension fund and then rented to a tenant. So the extra capital cost of construction is paid by the developer / fund but the running cost saving is taken by the tenant. So far in the UK at least there has been no real rent adjustment for this as rents are normally pegged to existing buildings. Developers / pension funds that I work with do want to build “green” but the cost appraisal / income calculation falls over. The UK Government via local planning rules has introduced high Breeam standards but these are not always being achieved as they are being successfully challenged on being uneconomic in areas of lower or even median rents. This needs to be urgently addressed, probably by tax breaks, so all new buildings and refurbishments are to a high standard.

Okay, after scrolling through the comments it seems like you have plans to do an EP on passive house. You are on top of it, I should have known! Well done!

Very informative and useful. Thanks for sharing.

On a social and community basis, I think it's better for us to reconnect with the natural world with green architecture. It's also better for the world.

Has Deltec Homes come across your net zero residential search yet Matt? Besides their 360˚ homes, they have green net zero homes. An old friend from high school runs it, neat stuff!

i find it funny how much footage of that failed "vertical forest" building that's now pretty much abandoned and at risk of crumbling at the weight of the overgrown flora that no one wants to trim, because it's impossible to live there thanks to the ungodly amount of mosquitoes. unless that's a different tree building...

[@firstlast-cs6eg]

How insulating is the fungus? Hopefully they don't make perfect the enemy of good enough. Like so what if some buildings can't be net zero because of the concentration of occupancy to roof space? That doesn't mean you can't produce the buildings greener and put solar panels or green space on the roof. Green space is basically putting gardens on the roof for insulation and shade, and it also means more plant growth for carbon capture and a pleasant place for occupants to visit.

Would love more talk on timber buildings. Their feasibility, how they've been doing until now, and their cost

[@UndecidedMF]

Good suggestion.

[@jesseyoung7855]

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.

Very interesting video. I've been seeing some on hempcrete. Also on bamboo. Just watched your video on algae for making plastics. A lot of new technologies coming out. Thanks for bringing them to us.

I have been designing and building passive solar homes for 40 years. The current retirement project is a net zero as well. When done thoughtfully it is simply the smartest way to design a building. I'm surprised LEED is still around as last time I looked into it the extra costs and effort to attain points and certification at times did not make financial sense to me. Simplicity, solar orientation and energy efficiency summarizes my goal when trying to attain the best results. Net zero is the most promising solution.

Hi Matt, love the format of these videos, do you have a reference list for the stats you've mentioned? Thanks

[@OutdoorLonghair]

It would be nice to get transparent Photo Voltaic windows to stop the UV heating in summer and take advantage of passive solar heating in the winter. Both would make a drastic difference in energy consumption. Also rooftop solar preheated then point of use water heaters. The solar heat storage potential of water has a lot to offer that we tend to overlook. The mycelium would work well for bag dome structures like they do with concrete, just inflate the double walled dome and let it grow to fill in between. ...Any way, it's Just a thought

[@cliffwoodbury5319]

Its pretty obvious that paying the extra money is well worth the price. Most will pay off the building just as fast and even if it takes some time longer these buildings are build so well they will be standing for 100's of years and the saving during the buildings lifetime would be mind boggling in comparison to less green buildings.

Cold Sores(Herpes) is best treated and Cured with Natural Roots and Herbs from my experience and how I was Cured of genital Herpes. Herbal medicine eradicate the virus, symptoms & Outbreak totally from inside and has no side effect... This is real and i used it just four weeks and tested Negative later. contact through whatsapp: [phone]or inbox email; [e-mail]

[@troyfred2562]

I am so on board for a lot of the ideas presented. We may have to rethink how we make cities. In a place the the US where we have ample land, but dense concentrations of people in cities (like New York, Chicago etc), perhaps we need to stop building close and up, and more spread out an wide, allowing more green areas (to beautify as well as for CO's reduction), as well as lowering what buildings need in the first place. If we made most of the power we need per structure, it becomes less needed to have more and more power plants.

Hard to imagine how you could miss Passive House, a German standard that has proven itself for over a 1/4 century. It is now the required standard for most all new buildings in the EU. "Passivhaus" includes all building types from houses to schools to skyscrapers. The modeled thermal performance requires they reduce heating and cooling demand by 90% compared to typical building methods. Subsequent evaluation has shown that on average they exceed their modeled performance - unlike many others' systems claims. The best and easiest way to get to net zero is to start by reducing energy demand in the first place. It's a lot easier to produce the energy you need on site when you barely use any. The primary objective is to focus on the passive part of the building - the envelope - and ensure superior windows, insulation, orientation, air tightness and detailing. Yet Passive Houses are fully compatible with most other green initiatives like living roofs and walls, rainwater collection, solar panels etc.

[@UndecidedMF]

Thanks for bringing that up. I didn't miss it, but left it out intentionally. This was focused on office buildings and large structures. A dedicated passive house video is in the works.

[@ronvandereerden4714]

@@UndecidedMF Well, Passive House is not limited in any way to small buildings. Here in Vancouver we have 42, 45 and 60 storey passive houses in the works - through they are residential. Looking forward to your coverage.
