[Equest-users] Effect of reflectivity on building energy consumption

[RobertWichert]

Dear Nimesh Prajapati,

It looks like your gas consumption went DOWN with increased 
absorptivity.  This makes sense to me since the building will absorb 
more solar heat and keep itself warm.

It looks like your electric consumption went UP with increased 
absorptivity.  This also makes sense since the building heat loads are 
increased by the additional solar heat.

Am I getting this correct?
