Building Materials and Man Made Global Warming. Really. We all know it by experience from a hot side walk or asphalt parking lot. Grass never gets hot. https://www.omicsgroup.org/journals...rban-city-area-2165-784X.1000110.php?aid=4790 This paper represents a comparative study aiming to investigate the heat impact on the vertical surfaces of buildings temperature based on their thermal behaviors. This study was carried out based on four building materials commonly used in Malaysia namely brick, concrete, granite and white concrete tiles. In order to investigate the thermal performance on the building materials, surface temperature sensors, data logging system as well as infrared thermography procedures were used, respectively. As the thermal impact to the materials was measured using infrared thermometric and thermographic, a field work of thermal value can be simply observed as a “seeing heat” effect. The results indicate that bricks had the capability to absorb and store heat greater than other materials during peak daytime event. The normalized (total heat/solar radiation) of brick materials was 0.093, which was the highest value compared to others. A brick material shows the highest impact of heat in 51% than white granite material and it releases a substantial amount of heat into the atmosphere through radiation and convection factors. The types of material used at exterior wall buildings have significant impact to the surrounding environment. The use of suitable materials contributes to the reduction of the air temperature due to heat transfer phenomena. Furthermore https://encrypted.google.com/search?q=how+hot+did+the+ashphalt+get?#q=how+hot+did+the+asphalt+get? Roads and lots could double as water heaters. Pavement covers as much as 45 percent of urban areas—and asphalt makes a sizeable contribution to the urban heat-island effect. On a steamy summer day, the surface of a road may get as hot as 60 degrees Celsius (140 degrees Fahrenheit). And https://encrypted.google.com/search?q=how+hot+did+the+side+walk+get? Wolke found that a hot sidewalk might only get up to 145°F. Anyone who is concerned about Man Made Climate Change should let others address CO2 Theory and address a real issue. Building materials. No plankton or similar will gobble up the expanding heat magnifying and storing systems of man made construction. <applause> <applause> <bow> < stand up applause> <wave> Suggestions for more earth neutral material except, Earth. Grass won't grow on the sides of high rise towers, will it? Maybe something like a Space Shuttle tile but designed for our lower temperature requirements. Or something being developed for space vehicle reentry heat shielding that might "spin off" to the construction industry. MRI's are an aerospace "spin off". Moi r > g Across an immense, unguarded, ethereal border, Canadians, cool and unsympathetic, regard our America with envious eyes and slowly and surely draw their plans against us.
It is a trade off. The heat absorbed in summer is a negative, The heat absorbed in cooler months/winter is a positive. Passive solar design is not new at all. Plant leafy trees on the sunny side of your house. In summer they will provide shielding from heat; in the winter the leaves fall off, the sun gets through, and you get a little extra warmth. There are several dynamics to this. In the end however, an existing home is more environmentally friendly than a new home because no new materials are needed and no new waste is created.
Not about comfort. About weather altering construction getting bigger and bigger as a major player in Man Made Climate Change, such as less rain around big cities and sprawl in the Midwest & drought for farmers. What's the alternative for asphalt? Wood has good thermal properties for buildings but, unfortunately it is flammable.
It is about comfort. Weather altering construction would include servicing the residents with energy. Even the EPA discusses the things I have discussed. You were the one who brought up the subject of heat islands. Part of the reason they exist is because of lack of trees. Trees serve multiple purposes. You don't necessarily need an alternative to asphalt--you just have to create gaps in in. An alternative is cobblestones/pavers though as it allows the water to better soak into the water table. Roofs can be painted white but people don't like white roofs because they show stains. There are green roofs which are covered in vegetation. Parking lots could be reduced in size or allowed to be made of something other than concrete or asphalt.
So is breaking up parking lots. I have seen a study somewhere or the other that between 50-90% of the acreage in our larger cities is hardscaped. I was watching a city council meeting on TV once that convinced me that my city doesn't have a clue what they are doing in this regard. First in one part of the city, they were voting to approve a plan to allegedly fight heat island effects in that area that included cutting down the trees and replacing them with flower pots hanging on light posts among other ridiculously wrong ideas. In the same meeting they turned down a zoning appeal by a business that wanted to have less than the required number of paved parking spaces for the size of the building they were constructing. We have some ridiculous requirements in that regard mostly as a way of forcing all commercial property to now be built in high density commercial sectors instead of being scattered about which in turn aggrevates the heat island effect, There is one area of the city that is on a hill in full sun with hardly a tree of any size in sight because of these ridiculous parking lot requirements and other than Walmart on Black Friday, you will never see one of these parking lots even close to full.
Another idea I saw in Las Vegas - they had a parking area that was "roofed" with solar panels that shaded the cars. Trees don't do well there.
Somewhere or the other I have seen parking decks covered with vegetation. I forget where but it was kind of neat looking. Of course, you would probably get sued for a million if someone got stung by a bee at one of those. I would prefer parking decks over these vast expanse parking lots but at something like $30K/space to construct, they are pricey.
I know a contractor friend who is also a representative of a company that can provide a thin, insulating, 'paint' to any building but the cost is sometimes prohibitive.
Well... Asbestos is a mineral that was mined since the ancients and was considered the wonder mineral since it's water resistant, weather resistant, insulating, electricity proof and flexible. This mineral was mined and by the 20th century, in my country at least, saw a ban of brown and blue types of asbestos. in 1985 this was by act of parliament prohibited because, the hazards of asbestos to the lungs wasn't diagnosed until such a build up was terminal, years later. The nature of this danger is dose/exposure based, where the more exposure to the mineral when it's disturbed/broken is bad, and builds up and the poor soul doesn't even know until it's too late. In 1999, in the UK, the last of the three types of asbestos 'White Asbestos' the form of asbestos that was considered the least harmful, due to the same of the mineral being pine needle shaped rather than a jagged spiky shaped mineral (blue and brown asbestos) that was banned in 1985, this White Asbestos, the last to be banned in the UK was banned by act of parliament. It is practise to assume there's asbestos in any building built before the year 2000 until proved otherwise by tests and certifying it to be an asbestos free site. You have to apply to HSE to get that certificate. If your asbestos survey finds asbestos, it's then marked.noted. If it's broken/disturbed and proves harmful, then it must be removed. HSE is a government body for health and safety at work. It's a mineral that's been mined because it was considered a miracle since Ancient Rome to the 1980's... Has the halt in asbestos consumption (here) given way to other less heat resistant materials like glass? - the recent technological advances in sky scraper builds for bigger, stronger, lighter buildings/big shiny glass and steel making for perhaps huge green houses or concentrated communities (these buildings are using energy 24/7) spread out over the pavement/street and all the activity in the streets like power cables, gas/propane piping, jet fuel for airport to airport, the London Underground, Crossrail, WiFi fibre optic cables, the sewers; all this activity going on under a surface that also makes it warmer because it's tarmac. A airport runway is to a highway as a highway is to a driveway. The reason why airports are the hottest (LHR/London Heathrow is London's hottest location) is because the 2 runways there are thicker because they need to be stronger for all the take offs and landings. That huge lump of tarmac at the airport, where the jet fuel gets piped to and from LGW/London's Gatwick Airport. I shouldn't imagine all the jet fumes making things any easier, but those runways can get hot.
How about draping buildings in "shade cloth" such a used by plant nurseries. Truly I hang shade cloth from the eaves of my home to keep the sun off the stucco and one can feel the difference between the shaded and the sun lit stucco. A non heat sink material that allows air flow between the building and the drape. Maybe something like blinds that adjust to keep the sun from getting through. This is about neutralizing the building as a heat sink. Not interior comfort. Okay? For now.
In my neighborhood the cats would climb up and down it and rip it to shreds. There are lots of things that could work but zoning laws, building codes etc are going to be the bane of many many people who try such things.
This guy is brilliant. I believe he designed Ford's HQ. https://www.amazon.com/William-McDonough/e/B001KIKWHM He designs products by only doing "good", less bad is still bad and hurts in the long run.
I read your link and his Wiki page but, don't see anything about addressing the heat islands from buildings & roads, per #1 upload. Did I miss something? Please point it out.
Yup.... terrible thinking....... https://permaculturenews.org/2012/1...ack-where-it-belongs-in-the-earth-tedx-video/ TONY LOVELL ON SOIL CARBON: PUTTING CARBON BACK WHERE IT BELONGS – IN THE EARTH (TEDX VIDEO)
