The Influence Of Thermochromic Glazing Parameters On Energy Saving And Comfort Criteria.pdf

Identify the influence of thermochromic glazing parameters for office buildings in hot climates using dynamic building simulations and sensitivity analysis techniques.
Thermochromic glazing (TC) has the capability to modulate its thermo-optical properties dynamically and reversibly when a change in its temperature occurs.
TC glazing for building application has to be doped with other metals to improve its properties: transition temperature, visible transmittance, solar modulation.
TC glazing has a potential to: reduce energy consumption, improve thermal and visual comfort, has a greater efficiency for hot climates.
4096 simulations were performed using thermal and daylighting simulations with EnergyPlus and sensitivity analysis method with a Python code with the SAlib.
Analysis on several indexes and on 4 locations (hot tropical climates) office building configuration.
Moment-Independent Measure (Borgonovo, 2007): the assessment of “the influence of the entire input distribution on the entire output distribution without reference to a particular moment of the output”.
Normalized output indexes: energy consumption index (Iec), thermal comfort index (Ith), visual comfort index (Iv).
Distribution of input parameters: filtering model outputs according to a criteria, sorting given inputs by glazing size (small, medium, large).
Visible comfort: [0.70; 1]
Energy consumption: [0; 0.40]
