kfw 40 nh, for example, stipulates
The building may only be awarded QNG-PLUS if 1 • at least 70% of the wood, wood products and/or wood-based materials used can be proven to originate from sustainable forestry.
at least 30% of the mass of the concrete used in above-ground and underground construction, the earthworks materials and planting substrates (total mass) have a significant recycling content.
• Greenhouse gas emissions in the building life cycle do not exceed 28 kg CO2-equivalent/m² per year and 2 • the determined non-renewable primary energy demand in the building life cycle does not exceed 96 kWh/m² per year.
the client has contractually obligated all construction companies to comply with the QNG quality requirements for pollutant avoidance and the companies declare compliance upon completion of their services.
required evidence for 1 • listing of all used wood products or wood-based materials by trade including information on the percentage share of the total volume or total mass and the available certificates. For determining the absolute amount of wood, the reference size is to be standardized to mass or volume. • PEFC certificates (Programme for the Endorsement of Forest Certification Schemes) • FSC certificates (Forest Stewardship Council) • if applicable, comparable certificates or individual proofs confirming that the criteria of PEFC or FSC applicable for the respective country of origin are met • final invoices and scope of services of the trades with relevant materials in excerpts • delivery notes of certified wood or wood-based materials for 2 • mass balance of all used concretes, earth materials and planting substrates by trade including information on the percentage share of the total mass of the building material. • declaration by the construction companies regarding the standard-compliant use of recycled concrete. • test certificates for mineral recycling materials issued by recognized testing bodies (external monitoring). These must not be older than six months at the time of delivery of the recycled material. • delivery notes. • manufacturer declarations.
The building may only be awarded QNG-PLUS if 1 an analysis and assessment of the building’s hazard at the location by selected natural hazards has been conducted. Captured and assessed are the current and future hazard due to local consequences of climate change in relation to 1.1 winter storm, hail, heat, heavy rain, lightning strike, snow load, 1.2 flooding and 1.3 radon and 2 all known and expected above-average natural hazard risks at the location with structural or technical features of the building or the building’s nearby outdoor areas having been addressed and documented or organizational risk management measures provisioned within the building operation.
Supplementary assessment bases for 1.1 • For the analysis and assessment of the hazard from winter storm, hail, heat, heavy rain, lightning strike and snow load at the building site, the freely accessible information system “GIS-ImmoRisk Naturgefahren”1 (hereinafter “ImmoRisk”) must be used. for 1.2 • The basis for the analysis and assessment are available information in flood hazard maps or other suitable sources. The choice of data is up to the user. Data from public agencies are preferred. for 1.3 • The basis is the classification of the property as a radon precaution area according to the respective federal state’s classification. The Federal Office for Radiation Protection provides an overview for this purpose.
and so on and so forth. Only very few craftsmen continue to do that.
