Hi Chou,

I understand that the meaning of these loads are:
Monthly Heating/Cooling loads: it's the monthly average sume of all gains and loses of your space
Hourly gains: it indicates for every hour of a specific day what its the behaviuor of each kind of energy flow
Specific gain hourly or monthly allow you to know the behaviuor of that energy transferEach point allows you to know differents aspects. The first only gives you the total for every month, the second allows you analize what load is important in a specific day and the last aspect allows you to know the anual behaviuor of a specific transfer of energy.

I don't know if it's clearly now or I confuse you more
