        I had a query  whether  ASHRAE 90.1 mentions what value has to
be taken for wall and roof absorptance as it mentions for U value . As
absorptance value has great impact on heat gains and further on energy

Can we have a better wall absorptance in proposed case from base case
so to improve energy performance

Any response will be highly appreciable.
