Construction started in November 2022 and the building will be available for occupation in 2025.<\/p>\n<p>The building was designed and planned completely in <a href=\"https:\/\/www.pbctoday.co.uk\/news\/digital-construction\/bim-news\/vectorworks-officially-launches-its-2023-version-of-bim-and-cad-product-line\/115632\/\" target=\"_blank\" rel=\"noopener noreferrer\">Vectorworks Architect<\/a>, with model coordination occurring in BIMcollab. There is an above-ground planned floor area of approximately 19,500 m2, including a central atrium that helps <a href=\"https:\/\/www.pbctoday.co.uk\/news\/building-control-news\/natural-building-ventilation-importance\/107624\/\" target=\"_blank\" rel=\"noopener noreferrer\">circulate air vertically<\/a> to reduce energy requirements.<\/p>\n<p>Designed in the shape of an arc triangle; floor plate offsets provide visual interest and form a rooftop terrace that\u2019s partially covered and allows visitors to enjoy the view of Bern city as well as the distant Alps.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<h3 id=\"cmsTopBoundary\">Timber plays a significant role in the sustainable archictecture of BERN 131<\/h3>\n<div>\n<p>AEC designers chose to utilise timber in BERN 131 not only for efficiency purposes, but for the material&#8217;s green credentials as well.<\/p>\n<p>Wood is much lighter than steel or concrete, meaning use of heavy machinery on site can be reduced and more components can be prefabricated offsite. This can reduce embodied carbon in projects significantly, which is a huge benefit when embodied carbon in building projects accounts for roughly 13% of total global carbon emissions.<\/p>\n<p>Another benefit of timber construction is its <a href=\"https:\/\/www.pbctoday.co.uk\/news\/mmc-news\/can-timber-construction-help-the-industry-achieve-net-zero\/120370\/\" target=\"_blank\" rel=\"noopener noreferrer\">cost effectiveness, as a renewable resource<\/a>. The material is also incredibly durable if maintained well, with innovations in wood engineering such as cross-laminated timber (CLT), glued-laminated timber (glulam), and nail-laminated timber (NLT) allowing AEC professionals to construct wooden buildings that are much taller and more durable than has ever been possible.<\/p>\n<h3>A complete envelope and PV panels contribute to the development&#8217;s sustainability<\/h3>\n<p>Among other sustainable solutions in the BERN 131 project is a carefully planned HVAC concept, which partner Florian L\u00fcnstedt described:<\/p>\n<p>\u201cThe building technology concept was developed to use as little energy as possible for ventilation and heating as well as cooling. The atrium in the center of the building is used as an exhaust plenum. This means less energy is needed for air transportation. The whole mass of the building is used to store heat and cold.<\/p>\n<p>The envelope is well insulated so that little energy is lost in winter. Intelligent control of blinds allows solar gains in the winter and prevents high energy input in summer. Then, where possible, <a href=\"https:\/\/www.pbctoday.co.uk\/news\/energy-news\/pv-panels\/105300\/\" target=\"_blank\" rel=\"noopener noreferrer\">the roof is covered by photovoltaic panels<\/a>, as are the parapets of the fa\u00e7ade.\u201d<\/p>\n<\/div>\n<p><span style=\"color: #111111; font-family: Roboto, sans-serif; font-size: 22px;\">Atelier 5 relies on Vectorworks for design, analysis, and planning<\/span><\/p>\n<div class=\"\">\n<div class=\"container\">\n<div class=\"row\">\n<div class=\"col-12 col-md-10 offset-md-1\">\n<div>\n<p>Executing a large project like BERN 131 requires excellent planning and collaboration tools. Atelier 5 relied on\u00a0<a href=\"http:\/\/vectorworks.net\/architect\" target=\"_blank\" rel=\"noopener noreferrer\">Vectorworks Architect<\/a>\u00a0design and building information modeling (BIM) software for this project. L\u00fcnstedt said this about the software:<\/p>\n<p>\u201cWith the intelligent tools in Vectorworks, work processes can be accelerated, summarized, and simplified. The structuring of the floors with the referenced layers leads to a realistic model that can react quickly to adjustments, corrections, or revisions in the planning process.\u201d<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<div class=\"\">\n<div class=\"container\">\n<div class=\"row\">\n<div class=\"col-12 col-md-10 offset-md-1\">\n<h3>BIM was essential for the scale of sustainable architecture in the project<\/h3>\n<div>\n<p>The use of BIM was required by the client and defined the progression of the BERN 131 project. BIM allowed Atelier 5 to treat one model as the project\u2019s source of truth \u2014 from the model, the architecture firm created sectional and elevation plans, as well as various visualizations to communicate with stakeholders.<\/p>\n<p>Developer Losinger Marazzi will also use the model to determine material quantities and cost calculations, 3D coordination, and tenders.<\/p>\n<p>\u201cWorking with BIM was essential for this project,\u201d said Anna Trifari, BIM manager for the BERN 131 project. \u201cThe shape and structure of the building are very complex, which is why the 3D model has already been used in many situations for clarification and illustration. In addition, many different consultants and contractors were involved, so interdisciplinary exchange played an important role.\u201d<\/p>\n<p>Atelier 5 used the industry foundation classes (IFC) file format to collaborate with consultants. With Vectorworks, they exported an IFC-specified model and were able to import the IFC data from others. They also took advantage of the BIM collaboration file format (BCF) for BIM issue management. \u201cThe direct import of BCF files into Vectorworks and the subsequent editing of clashes are both very helpful and easy to use,\u201d Trifari said.<\/p>\n<p>\u201cWorking in 3D with Vectorworks works very well and we use the intelligent tools for almost all new projects,\u201d said Trifari. \u201cThe possibility to view the project in the model helps to understand complex situations better and faster. Time can be saved by using the purpose-built tools in the software and by automatically creating sections and views.\u201d<\/p>\n<\/div>\n<p><strong>This post originally appeared on the <a
