In Portugal, it was half, and in Austria, it was still a third. Despite the growth of cities, the dream of a little house in the countryside is widely held. <a href=\"https:\/\/de.statista.com\/statistik\/daten\/studie\/39010\/umfrage\/bestand-der-einfamilienhaeuser-in-deutschland-seit-2000\/\">In 2019, there were around 15.9 million single-family homes in Germany, with around 60 new ones being added every day<\/a>. In the USA, the number of newly built single-family homes increased by 12 percent in 2020. Even in a country as small as Switzerland, almost 6,500 new single-family homes are built every year.<\/p>\n<p>The ongoing boom in residential construction is hugely relevant for the climate. First, due to the rising global emissions in the construction sector, and second, because structures built today will probably still be standing in 20 to 30 years and therefore inevitably have an influence on the global carbon footprint. All in all, there is enormous climate protection potential here.<\/p>\n<\/div><\/section>\n<section  class='av_textblock_section av-hm5a1-23-ff01e895cd7257d0a28eed94e52ed896'  itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/BlogPosting\" itemprop=\"blogPost\" ><div class='avia_textblock'  itemprop=\"text\" ><div  class='hr av-42s8bh-25-1aaa26b604da7e9a9ce9c91c7d3f93dc hr-small  avia-builder-el-9  el_before_av_hr  avia-builder-el-first '><span class='hr-inner '><span class=\"hr-inner-style\"><\/span><\/span><\/div>\n<h2 style=\"text-align: center;\"><strong>\u201eEvery building that is planned from now on must already be well on its way to climate neutrality \u2013 starting with energy neutrality.\u201d<\/strong><\/h2>\n<p style=\"text-align: center;\"><em>\u2013 Zero Energy Project<\/em><\/p>\n<div  class='hr av-2grbp9-24-df43e31a381b2a70b8c8a70a4c1c841d hr-small  avia-builder-el-10  el_after_av_hr  avia-builder-el-last '><span class='hr-inner '><span class=\"hr-inner-style\"><\/span><\/span><\/div>\n<\/div><\/section>\n\n<style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-knzw0jz7-35ea99bd183b21f574d781a845c7ddd7\">\n#top .av_textblock_section.av-knzw0jz7-35ea99bd183b21f574d781a845c7ddd7 .avia_textblock{\n-webkit-column-count:2;\n-moz-column-count:2;\ncolumn-count:2;\n}\n\n@media only screen and (max-width: 989px){ \n#top .av_textblock_section.av-knzw0jz7-35ea99bd183b21f574d781a845c7ddd7 .avia_textblock{\ncolumn-count:1;\n}\n.av_textblock_section.av-knzw0jz7-35ea99bd183b21f574d781a845c7ddd7 .avia_textblock.av_multi_colums > p:first-child{\nmargin-top:0.85em;\n}\n}\n<\/style>\n<section  class='av_textblock_section av-knzw0jz7-35ea99bd183b21f574d781a845c7ddd7'  itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/BlogPosting\" itemprop=\"blogPost\" ><div class='avia_textblock av_multi_colums'  itemprop=\"text\" ><p>There are legislative initiatives for climate-friendly building worldwide. In the Canadian province of British Columbia, for example, the government has introduced the <em>Energy Step Code<\/em>, a five-step program according to which all newly built homes must demonstrate a net zero energy balance by 2032. According to the EU buildings directive, all new buildings must be designed as \u201cnearly zero-energy\u201d buildings from 2021, although the interpretation of the law is left to the member states.<\/p>\n<p>In Germany, the Buildings Energy Act (Geb\u00e4udenenergiegesetz \u2013 GEG) has been decisive for the modernization of existing and new buildings since November 1, 2020. Its minimum standards primarily relate to energy consumption for heating and heat protection. Stricter requirements apply to government-subsidized <a href=\"https:\/\/www.kfw.de\/inlandsfoerderung\/Privatpersonen\/Neubau\/Das-KfW-Effizienzhaus\/\">KfW 55, 40 or 40 Plus efficiency homes<\/a>, with the latter requiring homes to be able to generate and store their own power.<\/p>\n<p>However, the regulations that are currently applicable are in no way sufficient for enabling compliance with the Paris climate protection agreement. Even though everybody is talking about climate justice, it barely plays any role at all in private home construction. This is indeed regrettable, but also highly understandable in view of the personal and financial burden that building a house represents in most cases.<\/p>\n<\/div><\/section>\n<div class=\"flex_column av_one_full flex_column_div  avia-builder-el-12  el_after_av_textblock  el_before_av_textblock \"><div class=\"swe-special-images swe-special-images-1 subtitle\"><div class=\"image-container image-container-image-1\"><img decoding=\"async\" src=\"https:\/\/sonnenallee.sma.de\/wp-content\/uploads\/2021\/04\/NetZero_Teil1_900x666.jpg\" alt=\"\" aria-label=\"The Blue House in Erasmushove proves how stylish sustainable architecture is.\" \/><small class=\"copyright avia-copyright\">Source: Active House, www.activehouse.info<\/small><\/div><span class=\"image-subtitle\"><span class=\"image-subtitle-inner image-description\">The Blue House in Erasmushove proves how stylish sustainable architecture is.<\/span><\/span><div class=\"image-container image-container-image-2\"><div class=\"image-container-inner\"><img decoding=\"async\" src=\"https:\/\/sonnenallee.sma.de\/wp-content\/uploads\/2021\/04\/NetZero_Teil1_798x547.jpg\" alt=\"\" aria-label=\"The Blue House in Erasmushove proves how stylish sustainable architecture is.\" \/><small class=\"copyright avia-copyright\">Source: Active House, www.activehouse.info<\/small><\/div><\/div><\/div><\/div>\n<section  class='av_textblock_section av-knzw0jz7-19-a2b72025bf7f9329b7149d66bac80175'  itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/BlogPosting\" itemprop=\"blogPost\" ><div class='avia_textblock'  itemprop=\"text\" ><div  class='hr av-42s8bh-21-590f53abd0c2e22cce2bf4ae78bb619a hr-small  avia-builder-el-14  el_before_av_hr  avia-builder-el-first '><span class='hr-inner '><span class=\"hr-inner-style\"><\/span><\/span><\/div>\n<h2 style=\"text-align: center;\"><strong>\u201eThe nearly zero or very low amount of energy required should be covered to a very significant extent by energy from renewable sources, including energy from renewable sources produced on-site or nearby\u201c<\/strong><\/h2>\n<p style=\"text-align: center;\"><em>\u2013 EU buildings directive<\/em><\/p>\n<div  class='hr av-2grbp9-20-3a7141ad6172d42c83591931285b6718 hr-small  avia-builder-el-15  el_after_av_hr  avia-builder-el-last '><span class='hr-inner '><span class=\"hr-inner-style\"><\/span><\/span><\/div>\n<\/div><\/section>\n\n<style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-knzw0jz7-18-d169f99ca09952fc4650137821241ae2\">\n#top .av_textblock_section.av-knzw0jz7-18-d169f99ca09952fc4650137821241ae2 .avia_textblock{\n-webkit-column-count:2;\n-moz-column-count:2;\ncolumn-count:2;\n}\n\n@media only screen and (max-width: 989px){ \n#top .av_textblock_section.av-knzw0jz7-18-d169f99ca09952fc4650137821241ae2 .avia_textblock{\ncolumn-count:1;\n}\n.av_textblock_section.av-knzw0jz7-18-d169f99ca09952fc4650137821241ae2 .avia_textblock.av_multi_colums > p:first-child{\nmargin-top:0.85em;\n}\n}\n<\/style>\n<section  class='av_textblock_section av-knzw0jz7-18-d169f99ca09952fc4650137821241ae2'  itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/BlogPosting\" itemprop=\"blogPost\" ><div class='avia_textblock av_multi_colums'  itemprop=\"text\" ><p>In most cases, purchasing or building a home marks a new chapter in your life \u2013 starting a family or adding to it, a career move or inheritance. These are emotional topics and times, and climate change is perhaps not at the top of your internal to-do list. In addition, home-builders probably underestimate the climate protection potential of their little house.<\/p>\n<p>Anybody who still dares to tackle the topic must first master the technical jargon: eco-balance; efficiency house; primary, useful and end energy; insulation values; thermal bridges; etc. Consistent definitions? In your dreams. Because experts and a handful of idealists have been the ones to set the tone so far with regard to climate-neutral and sustainable construction, ways of thinking have become established that a lay person may find difficult to understand. Thus, when the energy requirements of a house are calculated, the power consumption of its occupants is generally left out in the cold. Aha.

At the same time, we&#8217;ve all seen very old timber buildings \u2013 so obviously this bias is wrong.\u201d He believes conventions play a massive role. \u201cThe first generation of prefabricated houses from the 1970s still influences many people today,\u201d said the planner. That leads to the contradiction: \u201cWe want to do something environmentally friendly, but we do not want to deviate from conventional buildings.\u201d Clay plaster and hemp insulation, in turn, generally do not find favor straight away.

Unfortunately not.<\/p>\n<p>After all, a zero energy or plus energy building is still a long way from being climate neutral in the sense of having completely balanced greenhouse gas emissions. A building is truly climate neutral only when it causes as many or fewer greenhouse gas emissions relative to what it saves over its entire service life or compensates for them by generating renewable energy. And this equation packs a punch, because the service life of a building begins with its construction, and construction begins with obtaining raw materials for its foundations \u2013 an almost endless chain of climate-damaging activities. All of their CO2 emissions must subsequently be compensated for, whereby climate-friendly construction, building materials and logistics have a positive influence on the eco-balance.<\/p>\n<p>\u201eIn principle, the environmental impact of a building in terms of production and disposal is not regulated in Germany,\u201d explained Joost Hartwig, Managing Director of the <em>Ina Planungsgesellschaft<\/em>. \u201cSo it can consume and emit as much as it wants during construction. The emissions accumulated by the first day of occupation equate to between 20 and 30 years of operation even by today\u2019s high efficiency standards. So I emit enough for the next 20 years in one go, just so that I can put up a new house. There you can see already that somehow the wrong things are being promoted.\u201c<\/p>\n<p>\u201eWe must look at the entire lifecycle of a building instead. I mean construction, use, maintenance and dismantling\u201c, explained Wolfgang Stumpf, course leader at the <em>Department for Building and Environment at the Danube University Krems<\/em> and a member of building lifecycle initiative <em>IG Lebenszyklus Bau<\/em>.<\/p>\n<\/div><\/section>\n<div  class='av_promobox av-knzwkz3c-c4b58090598614973f0efaaf307b720e avia-button-no  avia-builder-el-27  el_after_av_textblock  el_before_av_textblock '><div class='avia-promocontent'><p>With a climate-neutral building (net zero building), the balance of greenhouse gas emissions is offset over its lifecycle.<\/p>\n<p>When calculating a building\u2019s total emissions over its service life, the following factors need to be taken into account:<\/p>\n<p>\u2022 Extraction and production of raw materials including transport<br \/>\n\u2022 Construction including installation, transport and logistics<br \/>\n\u2022 Use, maintenance, repair, replacement parts, modification and renovation<br \/>\n\u2022 Demolition and disposal or recycling<\/p>\n<p>Here, the key is to reduce, reduce and reduce again. On the credit side, there are recycled and recyclable building materials and \u2013 very importantly \u2013 the output of energy for consumption elsewhere. For a climate-neutral building, it is not enough to supply yourself with energy. To compensate for the emissions from production and construction, ongoing overproduction of energy at your location is essential.<\/p>\n<\/div><\/div>\n<section  class='av_textblock_section av-hm5a1-10-0c10856ef12ac12d95078b4ab68fa059'  itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/BlogPosting\" itemprop=\"blogPost\" ><div class='avia_textblock'  itemprop=\"text\" ><div  class='hr av-42s8bh-9-10e213910ae618d0b79567af07fcdafa hr-small  avia-builder-el-29  el_before_av_hr  avia-builder-el-first '><span class='hr-inner '><span class=\"hr-inner-style\"><\/span><\/span><\/div>\n<h2 style=\"text-align: center;\"><strong>\u201eIt has great dynamism worldwide.\u201c<\/strong><\/h2>\n<p style=\"text-align: center;\"><em>\u2013 Felix Jansen, DGNB<\/em><\/p>\n<div  class='hr av-2grbp9-8-8d6fa835869301a018f4d6847536608e hr-small  avia-builder-el-30  el_after_av_hr  avia-builder-el-last '><span class='hr-inner '><span class=\"hr-inner-style\"><\/span><\/span><\/div>\n<\/div><\/section>\n\n<style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-knzwohlh-7267948731ce853e55cf97181b0f7baf\">\n#top .av_textblock_section.av-knzwohlh-7267948731ce853e55cf97181b0f7baf .avia_textblock{\n-webkit-column-count:2;\n-moz-column-count:2;\ncolumn-count:2;\n}\n\n@media only screen and (max-width: 989px){ \n#top .av_textblock_section.av-knzwohlh-7267948731ce853e55cf97181b0f7baf .avia_textblock{\ncolumn-count:1;\n}\n.av_textblock_section.av-knzwohlh-7267948731ce853e55cf97181b0f7baf .avia_textblock.av_multi_colums > p:first-child{\nmargin-top:0.85em;\n}\n}\n<\/style>\n<section  class='av_textblock_section av-knzwohlh-7267948731ce853e55cf97181b0f7baf'  itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/BlogPosting\" itemprop=\"blogPost\" ><div class='avia_textblock av_multi_colums'  itemprop=\"text\" ><p>In holding this view, the two experts are part of an international movement that believes more stringent standards are required in the interests of the climate goals.
