Zero Energy Building Economic and Energetic Assessment with Simulated and Real Data Using Photovoltaics and Water Flow Glazing

The new paradigm of Net Zero Energy buildings is a challenge for architects and engineers, especially in with large glazing areas. Water Flow Glazing (WFG) dynamic façade technology shown to reduce heating cooling loads significantly. Photovoltaic panels placed on building roofs can generate enough electricity from solar energy without generating greenhouse gases operation or taking up other footprints. This paper investigates the techno-economic viability grid-connected photovoltaic system combined water flow glazing. An accurate assessment economic energetic feasibility carried out through simulation software on-site tests an actual prototype. also includes analysis global warming potential reduction. A prototype WFG envelope has been tested. data reported primary savings 62% 60% CO2 equivalent emission reduction when comparing reference triple Finally, report array showed Yield Factor Levelized Cost system. Savings over operating lifetime compensate high initial investment that these two technologies require.
