CIBSE Gain - Temperature rise

Question

I understand that you get different heat gains in the following scenarios: 
 
 Within CIBSE gain tool allow temperature to rise by 1degC 
 Within room data increase summer design temp by 1degC 
 
 There is a calculation procedure for the first scenario in the Hevacomp manual, however can you advise where this calculation originates from? is it a CIBSE Guide etc?

Hi Michael 
 
This is from CIBSE Guide A - Section 5; Thermal response and plant sizing. 5.A2.5 - Effects of allowing room temperature to rise above set point
