In addition to a workshop and its own aircraft hangar complete with a replica of Lindbergh\u2019s Spirit of St. Louis, it also had all kinds of cutting-edge gadgets on display, such as a dishwasher and a refrigerator that could be operated without ice blocks. Keck\u2019s House of Tomorrow was also far ahead of its time in other respects. During construction, it was discovered by chance that the glass fronts resulted in pleasant temperatures even before a heating system was installed, and thus the first passive solar house of the modern era was born. The experience that Keck gained with his House of Tomorrow led to the development of the first Thermopane multi-pane insulating glass a few years later.<\/p>\n<\/div><\/section>\n\n<style

stands like a tree on a plot of land originally not considered suitable for development. The front of the building is glazed, while the back is thermally insulated. What makes it special is that the whole house slowly rotates on its axis. On hot days, the glass fa\u00e7ade is turned away from the sun; on cold days, it is turned toward it to take advantage of the greenhouse effect. The photovoltaic system on the roof also adjust itself to face the sun like a sunflower. The Heliotrope was the first PlusEnergy house in the world to produce more energy than it consumes. In addition to the PV system, there are tube collectors visibly attached to the balcony railings that heat the water and the rooms. Rainwater harvesting, composting toilets and a reed bed treatment plant help make the building fully renewable, emission-free and carbon-neutral.<\/p>\n<\/div><\/section>\n\n<style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-595ojv-7a6b7cf9e4f64feecf92a1261fb6bdcc\">\n#top .hr.hr-invisible.av-595ojv-7a6b7cf9e4f64feecf92a1261fb6bdcc{\nheight:25px;\n}\n<\/style>\n<div  class='hr av-595ojv-7a6b7cf9e4f64feecf92a1261fb6bdcc hr-invisible  avia-builder-el-13  el_after_av_textblock  el_before_swe_special_images '><span class='hr-inner '><span class=\"hr-inner-style\"><\/span><\/span><\/div>\n<div class=\"flex_column av_one_full flex_column_div  avia-builder-el-14  el_after_av_hr  el_before_av_textblock \"><div class=\"swe-special-images swe-special-images-2 text\"><div class=\"part-1\"><div class=\"image-container image-container-image-1\"><img decoding=\"async\" src=\"https:\/\/sonnenallee.sma.de\/wp-content\/uploads\/2023\/06\/Rolf_Disch2.jpg\" alt=\"\" aria-label=\"\" \/><\/div><div><\/div><div class=\"custom-text\"><section  class='av_textblock_section av-av_textblock-cec65c98b84b831c854269d805741d7d'  itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/BlogPosting\" itemprop=\"blogPost\" ><div class='avia_textblock'  itemprop=\"text\" ><p>The core of the Heliotrope \u2013 a 14-meter-high column with a diameter of almost three meters \u2013 was planned by Rolf Disch, a trained carpenter, to be made of wood. This proved to be one of the biggest challenges. \u201cThere are lots of holes in the column for the doors to rooms, and until then there was no method at all to calculate the structural analysis. That first had to be developed by mathematicians at the University of Zurich,\u201d recalled Disch. \u201cThe next big challenge was to find the right glue for the wood. \u201cIt needed to be just as flexible or rigid as the wood in order to withstand the lateral stresses resulting from strong winds.\u201d<\/p>\n<\/div><\/section><\/div><\/div><div class=\"part-2\"><div class=\"image-container image-container-image-2\"><div class=\"image-container-inner\"><img decoding=\"async\" src=\"https:\/\/sonnenallee.sma.de\/wp-content\/uploads\/2023\/06\/Heliotrop_Kern.jpg\" alt=\"\" aria-label=\"\" \/><\/div><\/div><\/div><\/div><\/div>\n<section  class='av_textblock_section av-ljfhmrt5-b03ffd82a3e6949d582bce4a36655966'  itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/BlogPosting\" itemprop=\"blogPost\" ><div class='avia_textblock'  itemprop=\"text\" ><p>The Heliotrope has now stood on its wooden base for almost 30 years and bears witness to the beginnings of sustainable building in the 1990s. It is also the first protected historic building where the photovoltaic system is covered by the protected status.<\/p>\n<h2>\u201cFar too expensive; won\u2019t work\u201d<\/h2>\n<p>For architect Rolf Disch, the Heliotrope was by no means a one-hit wonder. For EXPO 2000, his firm built the \u201cSolar Settlement at Schlierberg\u201d in Freiburg, comprising 59 residential buildings built from timber and with roofs made of photovoltaic modules, as well as the \u201cSun Ship\u201d commercial and residential building. At the time, neither banks nor developers were willing to undertake the project. \u201cEveryone said it was far too expensive and wouldn\u2019t work,\u201d said Disch. \u201cBut I wanted to know for sure, so I founded a property development company myself. We finally financed the project on the private capital market with the support of Alfred Ritter and his sister Marli Hoppe Ritter of Ritter Sport, who had faith in us.\u201d Today, the solar-powered housing development generates around 420,000 kWh of solar power a year, and as in Utrecht\u2019s new <a href=\"https:\/\/sonnenallee.sma.de\/elektromobilitaet\/die-stadt-als-reallabor\/\"

The <a href=\"https:\/\/www.klimahaeuser-schallstadt.de\/\" target=\"_blank\" rel=\"noopener\">Schallstadt climate houses<\/a> are the architect\u2019s first PlusEnergy buildings to feature built-in cooling. Quite simply, in summer, cold water flows through the underfloor heating system instead of hot water. \u201cTen or fifteen years ago, I would have thought that we\u2019d have to make it work without cooling,\u201d said project manager Dr. Tobias Bube. \u201cBut the last ten summers here have been the ten hottest since climate records began. We are in the midst of climate change and the summers are terribly hot \u2013 there is simply nothing else we can do. Heating is one thing, but cooling is also becoming more important.\u201d The building design also allows for transportation in the form of electric bicycles and electric car-sharing to encourage residents to forgo owning cars. The underground parking garage under the building will be closed to internal combustion vehicles and reserved for electric cars and bicycles.<\/p>\n<\/div><\/section>\n\n<style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-215n83v-ec0416d985dde4173bb985389fa8652b\">\n#top .hr.hr-invisible.av-215n83v-ec0416d985dde4173bb985389fa8652b{\nheight:50px;\n}\n<\/style>\n<div  class='hr av-215n83v-ec0416d985dde4173bb985389fa8652b hr-invisible  avia-builder-el-24  el_after_av_textblock  el_before_av_image '><span class='hr-inner '><span class=\"hr-inner-style\"><\/span><\/span><\/div>\n\n<style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-ljfiba6b-851654e19e8d37e7c6fa8fa5f287ebbb\">\n.avia-image-container.av-ljfiba6b-851654e19e8d37e7c6fa8fa5f287ebbb img.avia_image{\nbox-shadow:none;\n}\n.avia-image-container.av-ljfiba6b-851654e19e8d37e7c6fa8fa5f287ebbb .av-image-caption-overlay-center{\ncolor:#ffffff;\n}\n<\/style>\n<div  class='avia-image-container av-ljfiba6b-851654e19e8d37e7c6fa8fa5f287ebbb av-styling- avia-align-center  avia-builder-el-25  el_after_av_hr  el_before_av_hr '   itemprop=\"image\" itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/ImageObject\" ><div class=\"avia-image-container-inner\"><div class=\"avia-image-overlay-wrap\"><img decoding=\"async\" class='wp-image-12824 avia-img-lazy-loading-not-12824 avia_image ' src=\"https:\/\/sonnenallee.sma.de\/wp-content\/uploads\/2023\/06\/SMA_Sonnen_Artikel_Solararchitektur_Weiermatten_900x666.jpg\" alt='' title='SMA_Sonnen_Artikel_Solararchitektur_Weiermatten_900x666'  height=\"666\" width=\"900\"  itemprop=\"thumbnailUrl\" srcset=\"https:\/\/sonnenallee.sma.de\/wp-content\/uploads\/2023\/06\/SMA_Sonnen_Artikel_Solararchitektur_Weiermatten_900x666.jpg 900w, https:\/\/sonnenallee.sma.de\/wp-content\/uploads\/2023\/06\/SMA_Sonnen_Artikel_Solararchitektur_Weiermatten_900x666-300x222.jpg 300w, https:\/\/sonnenallee.sma.de\/wp-content\/uploads\/2023\/06\/SMA_Sonnen_Artikel_Solararchitektur_Weiermatten_900x666-768x568.jpg 768w, https:\/\/sonnenallee.sma.de\/wp-content\/uploads\/2023\/06\/SMA_Sonnen_Artikel_Solararchitektur_Weiermatten_900x666-705x522.jpg 705w\" sizes=\"(max-width: 900px) 100vw, 900px\" \/><\/div><\/div><\/div>\n\n<style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-1tdp7gr-9fbb7598496f6fab64d8bdf46397ab56\">\n#top .hr.hr-invisible.av-1tdp7gr-9fbb7598496f6fab64d8bdf46397ab56{\nheight:50px;\n}\n<\/style>\n<div  class='hr av-1tdp7gr-9fbb7598496f6fab64d8bdf46397ab56 hr-invisible  avia-builder-el-26  el_after_av_image  el_before_av_three_fourth '><span class='hr-inner '><span class=\"hr-inner-style\"><\/span><\/span><\/div>\n<div class='flex_column av-1snx4yz-2b5eec79b43ab030deeff6b27964f950 av_three_fourth  avia-builder-el-27  el_after_av_hr  el_before_av_one_fourth  first flex_column_div '     ><section  class='av_textblock_section av-ljfiukaa-ad1013073acfa7aa564d9b23c3a7f1c5'  itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/BlogPosting\" itemprop=\"blogPost\" ><div class='avia_textblock'  itemprop=\"text\" ><h2>Showcase of an Austrian pioneer\u2019s work<\/h2>\n<p>Like Disch, Austrian Georg W.

[\u2026] As a result of this, we have been able to develop our avant-garde buildings into net plus-energy buildings, make increased use of renewable materials, develop concepts for self-sufficient urban districts, and also realize new concepts for communal living.\u201d What is also nice about this \u201cexciting logbook from the architect\u2019s point of view\u201d (publisher), with its chronological overview of projects from social housing to row houses, is that emerging problems have not been left out.<\/p>\n<\/div><\/section><\/div><div class='flex_column av-10ohk97-4cdc6ba1409e37162a2b51a93fe18bd9 av_one_fourth  avia-builder-el-29  el_after_av_three_fourth  el_before_av_hr  flex_column_div '     ><style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-ljfiwcfs-9c2f378bd08c1268f7ec4613fd77a704\">\n.avia-image-container.av-ljfiwcfs-9c2f378bd08c1268f7ec4613fd77a704 img.avia_image{\nbox-shadow:none;\n}\n.avia-image-container.av-ljfiwcfs-9c2f378bd08c1268f7ec4613fd77a704 .av-image-caption-overlay-center{\ncolor:#ffffff;\n}\n<\/style>\n<div  class='avia-image-container av-ljfiwcfs-9c2f378bd08c1268f7ec4613fd77a704 av-styling- avia-align-center  avia-builder-el-30  avia-builder-el-no-sibling '   itemprop=\"image\" itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/ImageObject\" ><div class=\"avia-image-container-inner\"><div class=\"avia-image-overlay-wrap\"><img decoding=\"async\" class='wp-image-12832 avia-img-lazy-loading-not-12832 avia_image ' src=\"https:\/\/sonnenallee.sma.de\/wp-content\/uploads\/2023\/06\/SMA_Sonnen_Artikel_Solararchitektur_Georg_Reinberg_900x666.jpg\" alt='' title='SMA_Sonnen_Artikel_Solararchitektur_Georg_Reinberg_900x666'  height=\"900\" width=\"666\"  itemprop=\"thumbnailUrl\" srcset=\"https:\/\/sonnenallee.sma.de\/wp-content\/uploads\/2023\/06\/SMA_Sonnen_Artikel_Solararchitektur_Georg_Reinberg_900x666.jpg 666w, https:\/\/sonnenallee.sma.de\/wp-content\/uploads\/2023\/06\/SMA_Sonnen_Artikel_Solararchitektur_Georg_Reinberg_900x666-222x300.jpg 222w, https:\/\/sonnenallee.sma.de\/wp-content\/uploads\/2023\/06\/SMA_Sonnen_Artikel_Solararchitektur_Georg_Reinberg_900x666-522x705.jpg 522w\" sizes=\"(max-width: 666px) 100vw, 666px\" \/><\/div><\/div><\/div><\/div>\n<style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-v8o3e3-0db541c6b00292cd8356c45021b86ef9\">\n#top .hr.hr-invisible.av-v8o3e3-0db541c6b00292cd8356c45021b86ef9{\nheight:50px;\n}\n<\/style>\n<div  class='hr av-v8o3e3-0db541c6b00292cd8356c45021b86ef9 hr-invisible  avia-builder-el-31  el_after_av_one_fourth  el_before_av_textblock '><span class='hr-inner '><span class=\"hr-inner-style\"><\/span><\/span><\/div>\n<section  class='av_textblock_section av-ljgsue61-217ac817cbd1fa952cd5bc14ae86c952'  itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/BlogPosting\" itemprop=\"blogPost\" ><div class='avia_textblock'  itemprop=\"text\" ><h2>SMA supports young architects at the Solar Decathlon<\/h2>\n<p>In 2022, the international\u00a0<a href=\"https:\/\/sde21.eu\/de\/\" target=\"_blank\" rel=\"noopener\">Solar Decathlon Europe 2021\/2022<\/a>\u00a0competition was held in Germany for the first time.
