That was the\nfirst time I dealt with the issue of shading in the urban area,\u201d she says.<\/p>\n\n\n\n<p>For Anai Green, it was a defining period. She kept mulling over\ndifferent approaches to shading and lighting, but also light pollution and the\nissue of excessive heat production in the city, known as&nbsp;the <a href=\"https:\/\/www.sciencedirect.com\/science\/article\/pii\/S0301479717303201\">urban heat island effect<\/a>. The right technology for her idea did not yet exist, and when it\nbecame available, it was too expensive.&nbsp;<\/p>\n\n\n\n<p>\u201cI wanted something that combines shading and lighting, while at the same time reduces light pollution \u2013 but what I had in mind wasn\u2019t practicable at the time, so I waited. As soon as the materials and technology I needed for my idea became available at an affordable price, I created Lumiweave.\u201d<\/p>\n\n\n\n<p>Green describes Lumiweave as an &#8220;advanced multilayer fabric&#8221; composed of four layers, each with an individual function. And although the concept itself sounds tangible, the intricate technology that goes into the development of the fabric is everything but simple. &#8220;The main components of Lumiweave are a flexible OPV (organic photovoltaic) sheet that is adhered to a UV resistant fabric. This fabric is imprinted with conductive copper-based ink that is acting as a circuit board. Intertwined with this fabric are polymer strips with LEDs.&#8221; <\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" width=\"708\" height=\"1024\" src=\"https:\/\/www.zavit.org.il\/intl\/wp-content\/uploads\/2020\/10\/Luminweave_Anai-Green-Tel-Aviv-708x1024.jpg\" alt=\"\" class=\"wp-image-3482\" srcset=\"https:\/\/www.zavit.org.il\/intl\/wp-content\/uploads\/2020\/10\/Luminweave_Anai-Green-Tel-Aviv-708x1024.jpg 708w, https:\/\/www.zavit.org.il\/intl\/wp-content\/uploads\/2020\/10\/Luminweave_Anai-Green-Tel-Aviv-207x300.jpg 207w, https:\/\/www.zavit.org.il\/intl\/wp-content\/uploads\/2020\/10\/Luminweave_Anai-Green-Tel-Aviv-768x1111.jpg 768w, https:\/\/www.zavit.org.il\/intl\/wp-content\/uploads\/2020\/10\/Luminweave_Anai-Green-Tel-Aviv-1062x1536.jpg 1062w, https:\/\/www.zavit.org.il\/intl\/wp-content\/uploads\/2020\/10\/Luminweave_Anai-Green-Tel-Aviv-1416x2048.jpg 1416w, https:\/\/www.zavit.org.il\/intl\/wp-content\/uploads\/2020\/10\/Luminweave_Anai-Green-Tel-Aviv-scaled.jpg 1770w\" sizes=\"(max-width: 708px) 100vw, 708px\" \/><figcaption><em>\u201cI wanted something that combined shading and lighting, while at the same time reduces light pollution.&#8221; &#8211; Anai Green, designer of Lumiweave.

Eitan Ben Ami, the director of the\nEnvironment and Sustainability Authority of Tel Aviv, sees a wide range of\npossible applications for Lumiweave. \u201cThe fabric can be used in many public\nplaces \u2013 any street, park, or parking lot. One of the first locations we\nthought about implementing Lumiweave is between the train station at Tel Aviv\nUniversity and the university campus. It\u2019s a long steep walk without any shade.\nAlso, the beach area would be a great place to try Lumiweave. That\u2019s why we\nlike the idea so much, it is widely applicable, and Tel Aviv has an abundance\nof space that doesn\u2019t have any shade.\u201d<\/p>\n\n\n\n<p>\u201cAlso, it\ndoes not have to be a permanent installation,\u201d adds Green. \u201cFor instance, we\nusually have many festivals in Israel, and those events consume a lot of electricity.\nLumiweave could really be an advantage in such a setting. It\u2019s very flexible\nand mobile.\u201d<\/p>\n\n\n\n<p>After\nexperts have deemed the concept worth supporting, the municipality has decided\nto provide the necessary resources to further develop and refine Lumiweave.\nAccording to Ben Ami, the city of Tel Aviv is always on the lookout for new\ninnovative ideas that can contribute to the city\u2019s sustainability and\nlivability. \u201cWe look anywhere possible for great new innovative ideas, and we\nvery much believe in the potential of Lumiwave,\u201d says Ben Ami.<\/p>\n\n\n\n<p>Various\noffices and departments are working together in order to provide the best\npossible support for Lumiweave and to ensure its success in Tel Aviv. As stated\nby Ben Ami, the Environment and Sustainability Authority is collaborating with\ndifferent departments of the Tel Aviv Municipality like Tel Aviv Global, the\nDepartment for Gender Equality and Women Programs, the Innovation Department,\nTel Aviv Hub, and others.<\/p>\n\n\n\n<p>\u201cThe collaboration with different partners is what gives us the strength to pursue and successfully implement projects like Lumiweave. This is important to us. That\u2019s why we are still working together with EcoWave, another great climate initiative located in Jaffa, Tel Aviv\u2019s old city, and the winner of the first Women4Climate Tech Challenge last year,\u201d he adds.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" width=\"1024\" height=\"510\" src=\"https:\/\/www.zavit.org.il\/intl\/wp-content\/uploads\/2020\/10\/4.-Solution-Luminweave-Anai-Green-Tel-Aviv-1024x510.png\" alt=\"\" class=\"wp-image-3486\" srcset=\"https:\/\/www.zavit.org.il\/intl\/wp-content\/uploads\/2020\/10\/4.-Solution-Luminweave-Anai-Green-Tel-Aviv-1024x510.png 1024w, https:\/\/www.zavit.org.il\/intl\/wp-content\/uploads\/2020\/10\/4.-Solution-Luminweave-Anai-Green-Tel-Aviv-300x149.png 300w, https:\/\/www.zavit.org.il\/intl\/wp-content\/uploads\/2020\/10\/4.-Solution-Luminweave-Anai-Green-Tel-Aviv-768x382.png 768w, https:\/\/www.zavit.org.il\/intl\/wp-content\/uploads\/2020\/10\/4.-Solution-Luminweave-Anai-Green-Tel-Aviv-1536x765.png 1536w, https:\/\/www.zavit.org.il\/intl\/wp-content\/uploads\/2020\/10\/4.-Solution-Luminweave-Anai-Green-Tel-Aviv-2048x1019.png 2048w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><figcaption><em>A pilot of Lumiweave is planned to be implemented in Anai Green\u2019s hometown of Tel Aviv, as soon as a prototype is ready to be deployed. Photo: courtesy<\/em><\/figcaption><\/figure>\n\n\n\n<p class=\"has-medium-font-size\"><strong>Women4Climate\nTech Challenge<\/strong><\/p>\n\n\n\n<p>The Women4Climate Tech Challenge is an initiative by C40, \u201c<a href=\"https:\/\/www.c40.org\/about\">a network of the world\u2019s 94 largest cities, committed to addressing climate change<\/a>.\u201d The goal of the Women4Climate Tech Challenge is striving to diversify the innovation sector, which, according to Silvia Marcon, the head of Women4Climate, is heavily dominated by men. \u201cMen outnumber women 5 to 1 in the innovation sector, and men have also historically built most of our cities. We believe that with more diversification \u2013 and not only in innovation but the whole STEM sector (Science, technology, engineering, and mathematics) \u2013 we will make more progress tackling climate change in cities. We want to inspire and engage young women and create role models that give them the confidence to live up to their potential and become part of a change.\u201d<\/p>\n\n\n\n<p>This year, the Women4Climate Tech Challenge received 105 applications and is looking for ten finalists. The call for applications is open to any woman in any city that is part of the C40 initiative. The goal is to find the best woman-led climate-solutions, whether for city planning, climate change adaptation, renewable energies, or other climate-related concepts, and pair them with cities that are part of the selection process of the challenge.<\/p>\n\n\n\n<p>Marcon\nemphasizes that the goal of Women4Climate is not only to find the best idea but\nto ensure that each concept becomes a feasible project that can be incorporated\ninto the urban infrastructure. \u201cWorking with the 10 finalists and support them\nwith specific training like pitching and engaging with city officials is part\nof an important learning process. The presentation and communication of a\nproject are just as vital as the idea itself because it has to match the city\u2019s\nrequirements and planning objectives,\u201d says Marcon.<\/p>\n\n\n\n<p>&#8220;Working\nwith C40 projects is different than working with any other project,&#8221; says\nBen Ami. &#8220;C40 really provides the foundation and the support that young\nideas need in order to develop. From start to finish, C40 keeps guiding us as a\nprofessional team. Just recently, the city of Tel Aviv was the first city in\nIsrael to finish and present its climate adaptation plan before the government,\nin large part due to the support of C40. It&#8217;s a really unique\norganization,&#8221; he adds.<\/p>\n\n\n\n<p>&#8220;I&#8217;ve already participated in other tech competitions, but I must say none of them were like Women4Climate Tech Challenge. I really felt that the people at C40 cared about me. I received their support and advice every step of the way. It was wonderful. I strongly believe that with the help of C40 and the Tel Aviv Municipality, Lumiweave has the potential to contribute to the city&#8217;s sustainability and its climate adaptation,&#8221; Green concludes.<\/p>\n\n\n\n<p><em>This ZAVIT article was also published in&nbsp;<a href=\"https:\/\/www.israel21c.org\/smart-urban-fabric-provides-shade-and-solar-energy\/\">Israel21c<\/a>&nbsp;on 10\/22\/2020.<\/em><\/p>\n","protected":false},"excerpt":{"rendered":"<p>The idea for Lumiweave was born while Green was working on another project for the city of Bat Yam, just &#8230;<\/p>\n","protected":false},"author":182,"featured_media":3490,"comment_status":"open","ping_status":"open","sticky":true,"template":"","format":"standard","meta":[],"categories":[15,11,8],"tags":[],"acf":[],"post-meta-fields":{"_edit_lock":["1603718731:11"],"_thumbnail_id":["3490"],"_edit_last":["11"],"subtitle":["Anai Green, this year\u2019s winner of the Women4Climate Tech Challenge, has created a novel outdoor fabric called Lumiweave, combining the benefits of renewable off-the-grid solar energy with day-time shading in one material."],"_subtitle":["field_59d3d36ea7fe1"],"_wpml_media_duplicate":["1"],"_wpml_media_featured":["1"],"_oembed_65485f269d007320b20e3c651be75360":["<iframe title=\"Lumiweave \u2013 The evolution of light and shade\" width=\"640\" height=\"360\" src=\"https:\/\/www.youtube.com\/embed\/TbdRIcrftxY?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture\" allowfullscreen><\/iframe>"],"_oembed_time_65485f269d007320b20e3c651be75360":["1603700214"]},"_links":{"self":[{"href":"https:\/\/www.zavit.org.il\/intl\/wp-json\/wp\/v2\/posts\/3481"}],"collection":[{"href":"https:\/\/www.zavit.org.il\/intl\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.zavit.org.il\/intl\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.zavit.org.il\/intl\/wp-json\/wp\/v2\/users\/182"}],"replies":[{"embeddable":true,"href":"https:\/\/www.zavit.org.il\/intl\/wp-json\/wp\/v2\/comments?post=3481"}],"version-history":[{"count":12,"href":"https:\/\/www.zavit.org.il\/intl\/wp-json\/wp\/v2\/posts\/3481\/revisions"}],"predecessor-version":[{"id":3506,"href":"https:\/\/www.zavit.org.il\/intl\/wp-json\/wp\/v2\/posts\/3481\/revisions\/3506"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.zavit.org.il\/intl\/wp-json\/wp\/v2\/media\/3490"}],"wp:attachment":[{"href":"https:\/\/www.zavit.org.il\/intl\/wp-json\/wp\/v2\/media?parent=3481"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.zavit.org.il\/intl\/wp-json\/wp\/v2\/categories?post=3481"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.zavit.org.il\/intl\/wp-json\/wp\/v2\/tags?post=3481"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
