Summed total 123.1545 47.5058 215.2448 208.2254 248.9037

Sorry heres an update i was looking at the wrong results.

Heating = 123
Cooling = 47
Aux = 215
lighting = 208
DHW = 248

there quite different from what i quoted above

Like your saying dhw is quite high. seems kinda crazy that its twice the heating demand of the building

Ok, no problem. The cooling is still a small player as I suspected.

Looking at those numbers, it's not worth troubling yourself over the cooling. If I were you, instead of adding shading, I'd be focusing on lighting and fan powers and maybe trying to shave a little off the space heating side. The DHW is normally quite tricky to influence much but you never know your luck.
