There is one fundamental difference between your shot an the sample shot you linked that no one seems to be addressing: The sample has highly reflective windows on all the buildings, each of which are reflecting each other. There are reflections.
Your photo is of an isolated building that either does not appear to have very reflective windows, or is simply not reflecting anything other than a dull sky. If you want the same kind of
pop as the sample you are referring to, then you need to find the same kind of buildings in the same circumstances: They need to reflect each other!
If you photograph isolated buildings with windows reflecting nothing other than a bland sky, then you shouldn't expect anything other than bland windows. ;) Go downtown, or change the angle at which you are photographing to include more intriguing reflections...and I think your problems will solve themselves.
I do not believe any special processing was involved in the sample photo, either. There was obviously some exposure and contrast manipulation to the authors taste. There are other colors in the scene, as muted as they are. If there was any special processing, I'd say the author simply boosted the "Aqua" color channel's saturation setting a bit...and that's it. But I would NOT state that is the primary source of the intriguing reflections...the source of the intriguing reflections is simply the fact that there ARE reflections, a facet that is entirely lacking in your photo.
