No significant change in EUI by use of electrochromic windows

I have used electrochromic windows with four tint shades and the EUI did not decrease as it should have according to the study done by many. The EUI for the use of single-pane clear glass is 203.79 Kwh/m2 and the EUI for EC glazing is reduced to only 202.49 Kwh/m2. Is it a problem with the schedule or has something gone wrong?
