What’s New
- New article: Reversible Mechanical Connection — how to design joints so components can be released, inspected, and reused instead of destroyed during removal.
- New article: Layered Construction Sequencing — how to build in layer order so future crews can remove fast-changing parts without damaging slow ones.
- New article: Connection Hierarchy Mapping — how to classify building joints by release cycle, performance duty, and recoverable value before choosing the connection detail.
- New article: Disassembly-Ready Documentation Set — how to hand over the schedules, inventories, release instructions, and stewardship record future crews need to recover building components intact.
- New article: Building Resource Passport (BRP) — how asset-level resource records turn material-passport evidence into circularity, data-quality, carbon, and recovery signals owners and investors can use.
- New article: Material-Passport Schema and Interoperability — how to structure passport fields, identifiers, evidence, data quality, and exchange mappings so circular-building data can travel between systems.
- New article: BIM-Linked Material Tracking — how to keep material-passport data tied to model objects, quantities, locations, classifications, and as-built updates instead of a drifting spreadsheet.
- New article: Volumetric Modular Construction — how factory-built room modules can become recoverable assets when their boundaries, interfaces, records, and relocation routes are designed from the start.
- New article: Panelized Construction — how factory-made wall, floor, roof, and façade panels can become recoverable assemblies rather than larger pieces of mixed waste.
- New article: Cross-Laminated Timber (CLT) and Mass Timber — how engineered timber’s circular value depends on certification, connection design, moisture history, and credible recovery routes.
- New article: Hempcrete and Bio-Based Wall Systems — how hemp-lime walls can support circular construction when binder chemistry, moisture control, code pathway, and end-of-life separation are handled honestly.
- New article: Mycelium Composites in Construction — how to use grown fungal bio-composites without overclaiming their structural, moisture, fire, or end-of-life performance.
- New article: Adaptive Reuse — how to test whether an existing building can carry a new use before demolition destroys its structure, carbon stock, fabric, and recoverable material value.
- New article: Shearing Layers (Six S’s) — how to read a building as layers that change at different speeds so fast-changing work does not destroy long-life value.
- New article: Long Life, Loose Fit — how to design durable building layers and changeable infill so a building can keep serving new uses instead of defaulting to demolition.
- New article: Open Building (Support and Infill) — how to separate durable shared support from changeable infill so buildings can adapt without damaging their long-life layers.
- New article: Reused Structural Steel — how to recover beams, columns, and other members as identifiable products with the evidence needed for structural reuse rather than scrap recycling.
- New article: Recycled Concrete Aggregate (RCA) — and Its Limits — how to recover concrete as aggregate without confusing low-grade downcycling with closed-loop circularity.
- New article: Salvaged Building Components Marketplace — how recovered building products become specifiable, purchasable, and movable before demolition speed destroys their value.
- New article: Deconstruction Contract — how to pay for careful dismantling, documented recovery, quality grading, and reuse routing instead of only fast clearance.
- New article: Light-as-a-Service — how lighting performance contracts can align ownership, maintenance, data, finance, and recovery instead of merely financing an LED retrofit.
- New article: EU Level(s) Framework — how the European Commission’s common building-assessment framework turns circularity, whole-life carbon, resource use, resilience, comfort, and life-cycle value into comparable project evidence.
- New article: LEED v5 Circularity Treatment — how LEED v5 turns embodied carbon, reuse, product selection, product-circularity evidence, and waste diversion into certification prerequisites and credits.
- New article: Revised EU Construction Products Regulation (CPR) Effective 2026 — how EU product-market law changes construction-product data, digital passports, sustainability evidence, and circularity claims without by itself proving building-level recoverability.
- New article: Bankability Gap (Circular Construction Finance) — why circular construction needs finance-grade evidence before lenders, investors, and owners can credit its long-term value.
- New article: Circular Retrofit Investment Case — how to compare retrofit with demolition and replacement using retained material value, avoided embodied carbon, operational improvement, finance eligibility, and future adaptability in one asset case.
- New article: Performance-Contract Risk Dump — how circular service contracts fail when ownership, maintenance, finance, insurance, and recovery duties outrun the provider’s control and risk capacity.
- New article: Showcase-Pilot Trap — how to learn from circular-construction pilots without mistaking exceptional funding, procurement freedom, or publicity value for repeatable market proof.

What’s New
- New article: Butterfly Diagram (Technical and Biological Cycles) — how to sort circular building claims by the material route they actually depend on.
- New article: R-Strategies (R0–R9 / 9R Framework) — how to rank circular construction moves by the value they actually preserve.
- New article: Linear Construction (the “Take-Make-Demolish” Baseline) — how to recognize the one-way material path that circular building practice is trying to replace.
- New article: Embodied Carbon (vs Operational Carbon) — how to separate material-side emissions from the carbon cost of operating a building.
- New article: Whole-Life Carbon Assessment — how to place circular building claims inside a full life-cycle carbon boundary.
- New article: Buildings as Material Banks (BAMB) — how to treat a standing building as recoverable stock instead of future demolition waste.
- New article: Bolt Don’t Weld — how reversible mechanical fastening preserves component value for future removal, repair, and reuse.
- New article: Material Passport — how structured material and product records preserve the evidence needed for reuse, recovery, and circular asset decisions.
- New article: Digital Product Passport (DPP) for Construction Products — how EU product-level records carry construction-product evidence into circular building data.
