18:04:45 From Mark Gale - Low Carbon Gordano : Could everyone please state affiliation next to their name, thanks in advance. 18:09:27 From Chris Harmer : Will the overheads be made available? 18:10:14 From Anne Chapman, Green House : Jonathan has written a chapter in Green House's 2019 book 'Facing up to Climate Reality' on Linking Cities and the Climate: is urbanisation inevitable'. See https://www.greenhousethinktank.org/fucr-book.html 18:12:25 From Green House Thinktank : If the speakers agree we often put the presentations on our website. 18:15:33 From Duncan Baker-Brown : I’m happy with that... 18:17:25 From Duncan Baker-Brown : What a fabulous presentation from Jonathan….. always very good. 18:18:29 From Kirsten de Keyser : Will Jonathan's slides be available afterwards? Loads of really fantastic facts and figs there! 18:20:10 From Anne Chapman, Green House : Yes, I hope we can put them on the 'past events' page of www.greenhousethinktank.org, along with recordings of this event. URL for Maya's report - https://www.greenhousethinktank.org/uploads/4/8/3/2/48324387/urban_planning_hong_kong_style_aug2020.pdf 18:20:21 From Galaxy J3 : sorry missed much of the prev presentation interbet down very good Thank you re slides ..I would like then too 18:20:37 From Kirsten de Keyser : Thanks! 18:21:09 From Galaxy J3 : And me thanks 18:21:54 From Mark Gale - Low Carbon Gordano : How can we get our academic institutions to to use lean design in the steel and concrete elements of new buildings on their campuses. For example UWE has just built a new faculty building for engineering, which appears cost engineered and not resource engineered, an educational mistake? 18:22:15 From Tom Lines (Brighton & Hove Greens) : The pandemic has greatly accelerated existing trends towards homeworking and online retailing. These reduce the need for large offices, their dispersal into suburbs amd smaller towns, the use of much less space for shops and reduction in commuting. Town- and city-centre land and buildings can then be reused for housing or regreening. How much of an opportunity does that offer? 18:24:01 From Jay Ginn : shouldnt we embrace localisation instead of accepting irbanisation with all its downsides? 18:24:46 From shayok - 350 NYC : HK has a massive housing inequity and affordability issue. How is this a model? 18:25:47 From Duncan Baker-Brown : What urban model is affordable in a nonsense free-market economy like the one we live in? 18:25:56 From Peter Gringinger : Is continuing urbanisation really inevitable or desirable? Move to urban areas is often caused by lack of opportunities and/or land grabs and other undesirable social developments. 18:27:17 From shayok - 350 NYC : Will someone address the very expensive/inequitous waste management issues created by cities? 18:27:55 From Jay Ginn : seems to build on the ideas of le corbusier 18:28:42 From Prashant Vaze : The housing cost and inequality is not a result of the high rise, but the fact income is unequal, the developers are sitting on land (brownfield) that they refuse to develop to keep prices high. 18:28:55 From Prashant Vaze : referring to Hong Kong 18:30:59 From Peter Gringinger : With respect to resources use need to head towards Circular Cities 18:31:07 From shayok - 350 NYC : Pretty amazing that this speaker can completely ignore this: https://www.cnn.com/2020/04/25/asia/hong-kong-social-distancing-coronavirus-intl-hnk/index.html 18:31:40 From Stephen McKenna : Some thoughts - London is 50% greenspace and urban areas are low density. Former Chief Planning Officer for city says generally 6-8 storeys is ideal density and we should look at the volume not just the area covered by development. Urbanisation needs to be reduced at ground level aided by digitisation we don't need GF so much as in past so ground should be used for food growing, nature, carbon sinks etc. IN other countries material displacement is possible eg use of bamboo. Carbon role means villages are better than cities in many places. Compact city is better than linear in carbon terms. I am Cllr on planning cttee in Surrey. 18:32:39 From Mark Gale - Low Carbon Gordano : Add strawboard to timber a renewable resource that grows on an annual cycle and can then have its carbon locked up in the building for decades, win win! 18:40:45 From Mark Gale - Low Carbon Gordano : Buildings - This is the purpose we currently think we need it for, HOWEVER times change and it must be potentially adaptable for range of future uses. How easy is it to repurpose it should be the first question asked by its financiers. 18:45:17 From Kirsten de Keyser : That was awesome! Thanks Duncan 18:45:19 From johanna mawson : Lots of great references and ideas thank you 18:45:44 From Sarah Finch : Thank you Duncan - really interesting. masses of food for thought 18:45:54 From Lynette Chipp : Will this recording bb 18:45:55 From Cllr Jonathan Essex, Green House : @Duncan BB - great inspiring presentation. The solutions are out there already - and can be repurposed! 18:46:03 From Kirsten de Keyser : Where are Maya's slides available, her presentation was far too short! 18:46:29 From Mark Gale - Low Carbon Gordano : Problems or just challenges? 18:46:41 From Lynette Chipp : Will this recording be shared, please? I was late to get in and it is moving very fast. I'd love to be able to watch it later. 18:47:10 From Sarah Finch : Hi Lynette - yes - the recording will be available on YouTube and we’ll send everyone hte link 18:47:30 From Sarah Finch : Hi Kerstin - you can read the report Maya’s talk was based on here: https://www.greenhousethinktank.org/uploads/4/8/3/2/48324387/urban_planning_hong_kong_style_aug2020.pdf 18:47:35 From Lynette Chipp : Soo pleased about that. I couldn't get into last weeks either. 18:48:14 From Anne Chapman, Green House : The slides and the recording will be made available at https://www.greenhousethinktank.org/past-events.html 18:48:32 From Kirsten de Keyser : Thanks Sarah! 18:48:51 From Lynette Chipp : Thanks. 18:51:21 From Duncan Baker-Brown : Here here Becky! 18:52:40 From Prashant Vaze : how much do speakers think COVID and the switch to working from home will undermine city living in the longer term. Is Zoom-based work here to stay? 18:54:56 From Duncan Baker-Brown : Here is a link to the Wasted City book I referenced https://www.youtube.com/watch?v=6hcT8H0q9-M 18:56:14 From Duncan Baker-Brown : Actually that was a link to a video of Location & Vassall…. Here’s the book link https://valiz.nl/en/#publications 18:57:54 From johanna mawson : park hill in Sheffield is an interesting example - was very successful until de industrialisation steel workers loosing jobs and others steady decline - also indoor spaces good but sat in a bit of a bleak corbusian ‘landscape’ 19:01:14 From Neil Pitcairn (UKWIN) : How to ensure a healthy generational mix in high rise? Young families need accessible and safe play and mixing areas. Older people who may not need to "play" so much, need to socialise with all ages. 19:01:44 From Mark Gale - Low Carbon Gordano : Do you want to spend 30-40% of your income on food, I think not? I am a farmer 19:05:03 From Mark Gale - Low Carbon Gordano : Farming a very precarious life, thats why migration to the cities occurs. 19:05:41 From johanna mawson : How to ensure high rise is balanced by quality outdoor space and connectedness through densified urban areas - land values and ownership is a key barrier 19:06:05 From Maya De Souza : i agree Mark. Farming even more precarious with climate change. 19:06:13 From Jay Ginn : well said Jonathan 19:08:11 From johanna mawson : Maya spoke about Frieburg - there are some very successful urban developments providing high quality living environments served by great transport infrastructure - 19:09:05 From Maya De Souza : Yes - great community feel in places like Vauban - Freiburg. 19:09:10 From johanna mawson : Highly consultative approach to city administration led development that we don’t use here in uk 19:09:30 From Prashant Vaze : how much could taxation of unused bedrooms, underutilised brown field sites, taxation of second homes help densify cities without new build. It feels like a lot of the built environment is used to store wealth rather than live 19:10:45 From johanna mawson : and the lack of social housing 19:12:05 From Anne Chapman, Green House : Another good book on this, is 'Rethinking the Economics of Land and Housing', by Josh Ryan-Collins, Toby Lloyd and Laurie Macfarlane 19:12:20 From johanna mawson : And water quality issues - impact on the bay 19:14:43 From johanna mawson : and the outdoor space at park hill was poor 19:15:41 From Maya De Souza : In response to Joanna’s point, water quality much improved with the Harbour Area Treatment Schemes - they have an annual swim across the harbour with senior Env Dept officials joining in. Selling land at a high price enables the govt to pay for such schemes. 19:15:55 From johanna mawson : There is a very successful housing complex behind park hill but it is being sold off via right to buy as every where 19:16:14 From johanna mawson : called Hyde park 19:19:19 From johanna mawson : Yes there has been significant investment I worked with an engineer involved - but my point is when you get extreme densification these major structuralist interventions are needed with v high embodied impacts 19:20:01 From Maya De Souza : Some good projects using less concrete at London Olympics site.. any good examples of using concrete in a modular disassemblable way? 19:20:47 From Mark Gale - Low Carbon Gordano : 2nd staircase for your staff! 19:21:03 From Anne Chapman, Green House : If only! 19:21:37 From Lisa Mitchell : I have to leave now but thanks so much to all of the speakers tonight, some real food for thought. 19:22:31 From Neil Pitcairn (UKWIN) : A number of local authorities are reviewing their waste local plans. There should be opportunities to recast these plans so they are integrated with building codes, and space allotted to ensure reuse,disassembly and reassembly. 19:23:04 From Duncan Baker-Brown : Well said Jonathan - we need to mine the anthropocene and close down ‘normal mines 19:24:25 From Anne Chapman, Green House : On agriculture, I've just written this report - https://gef.eu/wp-content/uploads/2021/02/GEF-Agriculture-report-v4.pdf 19:24:34 From Prashant Vaze : How much can retrofit of old prewar homes actually improve the building envelope. Can it be made good enough to allow heat pumps be used to make net-zero homes? I feel people underestimate the difficulty of retrofit though I do agree there need 19:24:43 From Mark Gale - Low Carbon Gordano : Just to let everyone know a 1,100 ha (4 square mile) solar farm is proposed in east anglia on good quality arable land, Food or electricity, you can't eat the latter! 19:26:26 From Anne Chapman, Green House : You can still graze sheep beneath the solar PV, but I agree we should not be using good quality arable land, lots of other land that could be used. 19:27:23 From Mark Gale - Low Carbon Gordano : And roofscapes 19:27:56 From Anne Chapman, Green House : If you want to hear about future Green House events and publications you can sign up for our newsletter here - https://www.greenhousethinktank.org/support-us.html 19:28:31 From Neil Pitcairn (UKWIN) : UK building codes allow very small room spaces compared to other countries in Europe. Not compatible with home working! 19:28:39 From Duncan Baker-Brown : This was a brilliant event. Thank you! 19:28:42 From Maya De Souza : Good point Becky - investment is often associated with pouring concrete. 19:29:04 From Prashant Vaze : brilliant event thanks all of you and Anne 19:29:04 From Liz Batten - Transition Southampton : Thanks for a very interesting set of talks and lots to think about :) 19:29:16 From Cllr Jonathan Essex, Green House : https://www.chathamhouse.org/2018/06/making-concrete-change-innovation-low-carbon-cement-and-concrete. We need to Make Concrete Change! 19:29:24 From Maya De Souza : Thanks Duncan - great to hear your presentation on C/E! 19:29:30 From johanna mawson : Thank you all speakers - very thought provoking and some very interesting facts and examples 19:29:38 From Amy Smith : thank you 19:29:47 From Lynette Chipp : Thank you.
