Hello,
it depends what You exactly allow or not allow in your design...
For final design is needed for me to answer me many technical questions (geographic location, indoor technology equipment, building envelope - both of them for setting indoor heat gains, as well as outdoor heat gains ), your budget for cooling system, - wich could be a combination which uses heat-solar collectors with technology to use sun for cooling, or photo-voltaic solar collector to supply simply cooling technology machnery by electricity, each variant could be differently energy efficient with different financial pay-back period.
Are you willing do dispute and cooperate ?
