    Race-to-Zero November Dialogues Programme
    https://unfccc.int/climate-action/race-to-zero/race-to-zero-november-dialogues-programme

    On 9-19 November the High-Level Champions for Global Climate Action are convening the Race to Zero Dialogues, in close collaboration with the Marrakech Partnership. In the spirit of inclusivity, the events are being hosted across multiple time-zones, allowing myriad speakers from all over the world to reflect on progress made on mitigation and adaptation. 2020 has been a challenging year for everyone, but these dialogues will chart how entire sectors are already rapidly transitioning to a zero-carbon future. The Race To Zero Dialogues will serve as critical input to the UNFCCC Climate Dialogues from 23 Nov – Dec 4, which are advancing work to governing the rules of the Paris Agreement. Together, both Dialogues will set the stage for the Anniversary of the Paris Agreement on 12 December as the world embarks on the ‘Race to Zero’ towards COP26 in 2021.

    The water vapour and surface albedo feedbacks in that particular model are much stronger than in any of the CMIP models used in IPCC, which are more closely informed by observations & physical understanding



    Is the climate crisis pushing the world towards a ‘point of no return’? | The Independent
    https://www.independent.co.uk/...change/climate-change-crisis-tipping-point-world-warm-b1721822.html

    “The results presented in the paper are interesting but are really at odds with the science community’s understanding of how the climate is changing,” says Prof James Renwick, head of the school of geography, environment and earth sciences at the Victoria University of Wellington.

    “The latest round of climate model simulations show that if greenhouse gas emissions were to stop immediately, there is likely to be very little further increase in temperatures and no sign of warming resuming in future.”

    The models used by the IPCC are more advanced and better able to simulate the behaviour of the Earth’s feedback loops, says Prof Mark Maslin, a climate scientist at University College London.

    “These results do need to be confirmed by more complex climate models used in the IPCC reports, because these results come from one model which has not undergone the rigorous cross checking and testing that is usual for climate models,” he says.

    In their paper, the authors note the simplicity of their model by saying that they “encourage other model builders to explore our discovery in their [bigger] models, and report on their findings”.

    It is important to understand that it is not too late to take actions to address the climate crisis, says Prof Betts: “I really wouldn’t want people to take [the research paper] seriously and start getting worried that the climate catastrophe is now unavoidable.”

    Claims that the world is “doomed” to suffer extremely high levels of warming can be detrimental to global efforts to tackle the climate crisis, explains Leo Barasi, author of the Climate Majority.

    “Claims the world is irreversibly doomed to runaway warming, and no amount of emission cuts can help us, can always find an audience, just like claims that climate change is nothing to worry about,” he told The Independent.

    LINKOS: je to o ztrate obalky toho domu na m2 a rok, energie, ktera tu ztratu pokreje je jina vec.

    styl jakej o tom treba uvazuju ja v nasich proporcich - rozdil mezi pasivnim standardem a nasim nejakym zhruba nizkoenergetickym je 10 kWh/m2/rok (jsme vypoctove okolo 25, pasiv 15 nebo min). to znamena, pri nasi podlahovy plose, vypoctove spotrebu o 3 MWh/rok navic (oproti pasivu). jenze realne to jde pres ventilacni TC, ktery protoze se zivi vnitrnim vzduchem ma vysokou efektivitu, protoze stale stejne stabilni teplotu vstupniho vzduchu. tzn. pokud potrebujeme ziskat za rok celkove rekneme 7.5 MWh, tak v TC je spotrebovano realne okolo 2.5 MWh el. energie. zaroven ale spotreba TC na vytapeni je koncentrovana do ty nejchladnejsi casti roku - kdy se pro snizeni spotreby el. energie v TC pouziva krbova vlozka s vymenikem (ohriva akumulacni nadrz). rekneme ze teda potrebujeme dotovat par zimnich MWh drevem (tepelna energie, ktera omezi spotrebu energie tep. cerpadlem). tech par MWh je docela mala hromadka dreva u domu (rekneme do 3 m3?). je to cely orientacni, ale ramcove to tak bude.

    pro nas tohle reseni znamena, ze nemusime dum utesnovat (koncept hybridniho vetrani), neni tu ten koncept ty striktni regulace vstupu a vystupu vzduchu, ale vzduch se neustale vymenuje, jen neprichazi centralne.

    jestli tu sezonni vyssi spotrebu TC pokreje zadna nebo jedna nebo dve hromadky dreva mi treba v nasem pripade neprijde moc rozdil. spotrebu TC v prubehu roku (krom jinyho) by mel pokryvat solar + baterky.

    u tech nulovejch/pozitivnich domu mi prijde zradny to, ze tam lze spoustu veci skryt za to, ze se postavi obrovska FV, pricemz ale realne ten dum treba tak efektivni neni a pres zimu jede z gridu. v tom mi prijdou nejpoctivejsi ty offgrid reseni, pripadne reseni, ktery maj grid spis jen jako backup - tam pak nic nejde vypoctove nafejkovat :)

    Plans for 50,000 hydrogen-powered taxis in Paris – pv magazine International
    https://www.pv-magazine.com/2020/11/12/plans-for-50000-hydrogen-powered-taxis-in-paris/

    European electric transmission company body ENTSO-E has unveiled details of a project to install 11 GWh of electrolyzed hydrogen storage capacity across ten locations around the French capital by the end of the decade.

    ...

    The project envisages the construction of ten locations around the French capital, each of which would feature 20-50 MW of grid-connected electrolyzer capacity and 100-500 MWh of hydrogen gas storage capacity.

    ENTSO-E's summary of the scheme stated the hydrogen would be generated from electrolysis powered by “decarbonized and green electricity sources,” wording which suggests a role for nuclear or even for thermal power generated in carbon capture and storage facilities.

    PAD: tak pokud jsem správně pochopil koncept jedna se o náročnost domu "primární" tedy fosilní energie prepoctenou na metr čtvereční obytné plochy. Proto se do domů které jsou na hraně a nesplnily by pasiv často montuje tepelné čerpadlo.
    Nulové a aktivní k tomu mají ještě solární elektrárny atd...

    LINKOS: ja nerozporuju, ze cim vetsi je energeticka efektivita, tim lepe - ovsem je treba se divat na cely cyklus te energie. co je lepsi: postavit novy dum, treba i pasivni (vyroba vsech materialu, prace, doprava, zasitovani, dostavba navazujicich sluzeb jako mhd, skoly, atp) nebo rekonstrukce starsiho domku do nizkoenergeticeho standardu? techto konverzaci jsem mel s mamou fakt hodne (postupne se z pozice nadsence do pasivu zmenila na jejich kritika - hlavne rika, ze je fakt tezky to postavit tak, aby to opravdu fungovalo, za rozumne penize). nikomu to tlacit nebudu, ale pro me pasivni novostavba neni - ani z hlediska komfortu bydleni, ani financne, ani ekologicky. usetrene penize radeji investuju do vetsi fotovoltaiky, kterou mohu pritapet a v budoucnu treba i krmit stroje (auto, atp). ale kazdy to ma jinak - kdyz nekdo napriklad fakt chce stavet novostavbu, nechce topit biomasou, vyhovuje mu rekuperace, muze to davat smysl. bohudik mame na vyber;)

    Je to na delsi diskuzi. Resim to asi 3 roky, mam primy reference, byl jsem na par mistech a realizacich. Jeden z nejlepsich kamosu minuly rok kolaudoval nizkoenergeticky dum (3 skla, nadkrokevni izolace, 16cm PS, rekuperacka s aktivnim tepelnym cerpadlem), atd. Ted jsem tedy ve fazi ze znovu vsechno do zakladu proargumentovavat a vysvetlovat dusledky uz nedavam :-) Takze se omlouvam.

    Treba ta rekuperacni jednotka. V rekuperacce [kovovy vymenik, ucinnost 60+%] nebudu mit zabudovane tepelne cerpadlo ani prihrev, ale IR panely po baraku (uz timhle konceptem nedosahnes pasiv normativne). Mam argumenty proc jo a proc ne.

    Tady je to OT, v prislusnym auditku je to akorat na shit-storm + placani nesmyslu od ID: CUKI. Idealne pokec u pivka a projektu, beta-projektu a navrhu. Asi bych casem zalozil nejake auditko kam budu postovat ruzne fragmenty s obrazkama a argumentama. Ted na to nemam.

    LINKOS: Hele ja tu stavbu hodne resim a splneni normativnich naroku na pasiv, oproti kvalitni nizkoenergeticke stavbe je fakt velky financni krok a hlavne velky kompromis v uzivani. Neni to zdaleka jen o nejaky prolepeni oken, tesnosti obalky atp.

    Ja jsem se smiril ze budu mit treba z 95+% pasiv (klidne ve finale 97), ale ten posledni krok k dosazeni splneni normy platit nehodlam. Navic ani pasiv neni v dusledku uplny pasiv. Je to arbitrarne urcena norma a splnit jeji princip z 95% proste bohate staci.

    Less is More

    Book review: ‘Less is More: How Degrowth Will Save the World’ by Jason Hickel | degrowth.info
    https://www.degrowth.info/...k-review-less-is-more-how-degrowth-will-save-the-world-by-jason-hickel/

    The most valuable contribution of Less is More is that it provides an accessible and compelling introduction to ecological and social critiques of growth, and how degrowth could address these, for anyone who is remotely interested in a liveable future on this planet. Beyond the degrowth-curious then, this is a book that I can easily see becoming a staple of introductory reading lists on our current ecological crisis and ways forward. An introduction it certainly is though, and hopefully, for most readers Less is More will be just the start of their exploration of degrowth, rather than the full extent of it.

    Still, from a degrowther’s point of view, the arrival of Less is More means that you will no longer have to persuade your friends and relatives to wade through stuffy academic jargon for them to understand why you won’t shut up about this ‘degrowth’ thing. Jason Hickel has us covered.


    What does degrowth mean? A few points of clarification
    https://www.tandfonline.com/doi/abs/10.1080/14747731.2020.1812222

    Degrowth is a planned reduction of energy and resource use designed to bring the economy back into balance with the living world in a way that reduces inequality and improves human well-being. Over the past few years, the idea has attracted significant attention among academics and social movements, but for people new to the idea it raises a number of questions. Here I set out to clarify three specific issues: (1) I specify what degrowth means, and argue that the framing of degrowth is an asset, not a liability; (2) I explain how degrowth differs fundamentally from a recession; and (3) I affirm that degrowth is primarily focused on high-income nations, and explore the implications of degrowth for the global South.

    LINKOS: no tak pro nas to treba smysl nedavalo - tlustsi zdi, tzn. docela zvetseni pudorysu pri stejny podlahovy plose a celkem znatelnej vydaj navic. pokud to nakonec znamena, ze se pres zimu usetri par polen, je nekde mira, pres kterou to smysl nedava a to je potreba nejak zohlednit. samozrejme pokud to nekomu za investici stoji, at to udela. a to mluvim z perspektivy, kdy mi jde o moznost snizeni ty provozni uhlikovy stopy a moznost energeticko materialovy lokalizace. v tomhle ramci ten pasivninstandard pro nas vysel jako prehnanej (prehnane zamerenej na jeden parametr)

    TADEAS: ta náročnost pasivu oproti kvalitní nízkoenergetické stavbě není zas o tolik větší. Problém je v tom, že mnoho věcí co by měla mít každá nová stavba nejsou standart. Například těsnost obálky, páska okolo oken, dostatečná vrstva izolace pod paracety, dobře provedené zateplení stropu, odpovídající tloušťkou izolace. Atd...
    Pokud se na mnohých stavbách tyhle věci neřeší, tak parametry co mají mnohé domy splňovat splňují jen na papíře.
    Pokud je pak tlak na dodržení těchto věcí jen u pasivních domu není se co divit, že je na ně prohlíženo jako na drahé a složité. Přitom spousta věcí jsou docela jednoduchá řešení, jen pro stavebníky nejsou moc zažité
