Re: Simulating a GrassRoof

["Dr.Karl-Christian Rauch" <Rauch-Muenster@xxxxxxxxxxx>]

Dear Anil,
I remember an article in APPLIED ENERGY, Solar Energy Research
Volume 7 Nos. 1-3 November 1980, pp229-242
Applied Science Publishers Ltd., England, 1980

Heating and Cooling Buildings by Flow of Water over the Roof
Authors: M.S.Sodha, A.Srivastava, A.Kumar, and G.N.Tiwari
Centre of Energy Studies, Indian Institute of Technology, 
Hauz Khas, New Delhi, 110029, India

This paper presents an analysis for the reduction of the heat flux
that occurs by constant flow of water in a network of pipes buried 
in a roof.. An air gap is introduced into the roof to achieve maximum 
thermal load levelling (summer like winter).

Not quite yet what you are searching for; but indeed I think, this
is an interesting paper for your job.

Kind regards
Dr.Karl-Christian Rauch
