GLOBAL CO2 EMISSIONS ALONE. NOT ONLY THAT, IT ALSO CONSUMES MORE THAN HALF OF ALL MATERIAL RESOURCES AND PRODUCES BY FAR THE MOST WASTE. HOW CAN WE DEAL WITH OUR RAW MATERIALS MORE SUSTAINABLY IN THE FUTURE IN ORDER TO GENERATE LESS WASTE, CONSUME LESS ENERGY AND ULTIMATELY MINIMIZE CO2 EMISSIONS?

A CIRCULAR SYSTEM WITHIN BUILDINGS SERVE AS MATERIAL STORAGE FACILITIES IN ADDITION TO THEIR INTENDED FUNCTION MIGHT BE A WAY. WITHOUT LOSS, THE RESOURCES USED FOR CONSTRUCTION CAN BE REMOVED AT THE END OF THE BUILDING‘S LIFE AND REUSED FOR NEW PROJECTS OR RECYCLED IN AN OPTIMIZED WAY. FOR THIS VISION A NEW ARCHITECTURAL APPROACH IS NEEDED, WITH THE FOCUS ON DISASSEMBLY CONNECTIONS OF INDIVIDUAL COMPONENTS, ROBUST AND THUS DURABLE ELEMENTS THAT ARE PURE IN THEIR MATERIALITY. THE HOUSE OF JOINTS REPRESENTS A GUIDELINE TO IMPLEMENT THIS
VISION OF NEW ARCHITECTURE. STRUCTURED BY 5 LIFETIME LAYERS, BUILDING COMPONENTS CAN BE DESIGNED TO ANSWER SPECIAL REQUIREMENTS. STRUCTURAL COMPONENTS ARE MEANT TO BE ROBUST AND LONG LASTING. SKIN COMPONENTS ARE SUGGESTED TO BE PURE IN MATERIALITY, TO PROVIDE RECYCLING ABILITY AFTER ITS LIFE SPAN. THE SERVICE LAYER REQUIRES PLANNING SINCE IT HARDLY CAN BE OPTIMIZED IN MATERIAL. THE SPACE LAYER REQUIRES ALTERNATIVES THAT CAN SERVE LONGER THAN E.G. DRY WALLS AND AVOID WASTE. THE STUFF LAYER SERVES INDIVIDUAL NEEDS AND CAN BE OPTIMIZED BY DECISIONS TOWARDS SUSTAINABLY FURNITURE E.G. CONSIDERING THIS GUIDELINE A BUILDING CAN BE DISMANTLED EASILY INTO ITS RECYCLABLE/ REUSABLE COMPONENTS AND CAN PREPARE THE CITY FOR A FUTURE PIGGY BANK.
DURING THE DESIGN PROCESS, INFORMATION ON MATERIALS AND COMPONENTS USED CAN BE DOCUMENTED IN THE BIM MODEL SO THAT A DIGITAL PASSPORT CAN BE GENERATED AFTER COMPLETION. THE GOAL IS TO CREATE A DATA SET THROUGH THE DIGITAL DOCUMENTATION OF ALL BUILDINGS THAT OPTIMISES PROCESSES REGARDING RENOVATION AND REUSE. IN ADDITION, THESE STEP-BY- STEP INTERVENTIONS OF A BUILDING CAN BE DOCUMENTED. IN AN IDEAL IMPLEMENTATION OF THIS STRATEGY, THE CITY COULD BE OUR STOREHOUSE OF MATERIALS FROM WHICH WE HELP OURSELVES AND ACHIEVE AN OPTIMAL USE OF RESOURCES. UNTIL NOW, WE HAVE ONLY PLANNED BUILDINGS FOR THEIR USEFUL LIFE. WE SHOULD START PLANNING BEYOND THAT, TO KNOW WHAT HAPPENS TO THE MATERIAL OF A BUILDING AFTER ITS LIFETIME. THE ADDED VALUE FOR THE CITY IS CLEARLY CALCULABLE. BUILDINGS ARE NO LONGER POTENTIAL WASTE PRODUCERS, BUT VALUABLE MATERIAL STORES FROM WHICH THE CITY CAN BENEFIT. ULTIMATELY, THE MOST IMPORTANT THING FOR THE DESIGN PROCESS IS THE EXTERNAL APPEARANCE. WE SHOULD BECOME AWARE OF HOW WE INFLUENCE THE ARCHITECTURAL LANGUAGE WITH THE MEASURES MENTIONED. AS SOON AS WE DESIGN A BUILDING ACCESSIBLE TO DISMANTLING, WE REVEAL THE CONSTRUCTION AND PRESENT THE STRUCTURE AND CONNECTIONS. THE RESULT IS AUTOMATIC ARCHITECTURE THAT DEALS HONESTLY WITH ITS MATERIALS AND THEIR CONSTRUCTION AND MAKES THEM READABLE. THE WAY WE TRANSLATE THIS INTO ACTION COULD RESULT IN AN EXCITING NEW AESTHETIC.
