Life Cycle Assessment of Dynamic Water Flow Glazing Envelopes: A Case Study with Real Test Facilities

High initial costs hinder innovative technologies for building envelopes. Life Cycle Assessment (LCA) should consider energy savings to show relevant economic benefits and potential reduce consumption CO2 emissions. Cost (LCC) Energy (LCE) focus on investment, operation, maintenance, dismantling, disposal, and/or recycling the building. This study compares LCC LCE analysis of Water Flow Glazing (WFG) envelopes with traditional double triple glazing facades. The assessment considers initial, operational, disposal as well different systems heating cooling. Real prototypes have been built in two locations record real-world data yearly operational energy. WFG consistently showed a higher investment than glazing. final demonstrates that are better over operation phase only when it is compared double-glazing. However, 50 years concluded between 36% 66% emissions reduction 30% 70% could be achieved.
