At HOINKA, we support you from the initial planning stage through to successful certification. <\/p>\n<p data-path-to-node=\"8\">As of January 1, 2023, all sizes of residential buildings can be certified: The Assessment System for Sustainable Small-Scale Residential Construction (BNK) for buildings with 1 to 5 residential units and the Assessment System for Sustainable Buildings (BNG) for buildings with more than 5 residential units.<\/p>\n<h2 data-path-to-node=\"11\">The Key to Funding: BNK\/BNG as a Prerequisite for QNG and KfW<\/h2>\n<p data-path-to-node=\"12\">The BNG\/BNK certificate is one of the most important certifications required to obtain the <a href=\"https:\/\/hoinka.com\/leistungen\/qng\/\">QNG (Quality Seal for Sustainable Buildings)<\/a> and, consequently, to qualify for KfW\u2019s <a href=\"https:\/\/hoinka.com\/leistungen\/qng\/\">Climate-Friendly New Construction (KFN)<\/a> funding program.<\/p>\n<ul data-path-to-node=\"13\">\n<li>\n<p data-path-to-node=\"13,0,0\">Through the BEG program (Federal Funding for Energy-Efficient Buildings), you can obtain low-interest loans for climate-friendly new construction projects.<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"13,1,0\">Projects that meet the requirements for QNG-Plus or QNG-Premium and are awarded a sustainability certificate are eligible for even higher funding.<\/p>\n<\/li>\n<\/ul>\n<h2 data-path-to-node=\"15\">The Certification Process: How We Support You<\/h2>\n<p data-path-to-node=\"16\">The certification process runs parallel to the planning and construction of the building. A certified BNK\/BNG auditor will guide your project from the planning phase through to completion. Certification takes place in several structured steps:  <\/p>\n<ol start=\"1\" data-path-to-node=\"17\">\n<li>\n<p data-path-to-node=\"17,0,0\">Selecting a BNK\/BNG Auditor: These are experts in sustainable construction (such as architects, engineers, or energy consultants) who have been trained by BiRN (the Institute for Resource-Efficient and Sustainable Construction) and who will assist you with implementation.<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"17,1,0\">Registration of the project with BiRN: The client registers the building for certification and concludes contracts with the auditor and the BiRN certification body.<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"17,2,0\">Establishing Sustainable Planning Goals &#038; Documentation: Together, we define the goals, prepare the necessary documents, and, upon completion of construction, review the documentation to ensure the certificate is successfully issued.<\/p>\n<\/li>\n<\/ol>\n<h2 data-path-to-node=\"19\">An Overview of
