Sotiris asked the same question in Eplus mailing list, and someone
posted this link. I'll just post it here as well to share it with
the rest.<br>

were working on green roofs, but perhaps not same research
methodology/ scope. I am not doing green roof at this time
but I did it couple of years ago while I was doing my PhD at
PennState working under supervision of Dr. Jelena Srebric
and did all my experimental work inside an full-scale
environmental chamber. In that way I was able to control
environmental conditions such as radiation, air
temp/RH/speed. Moreover, I measured simultaneously
conduction, radiation (short and long wave), convection and
evapotranspiration, as well as water content of substrate,
LAI, plants and substrate temperature. It was a very
detailed work probably beyond the scope of Sotiris’ initial
question and I had to design and built a new apparatus to
measure all these heat fluxes. I would be glad to talk more
in detail, but perhaps we are going little bit beyond the
scope of this mail list.<o:p></o:p></span></p>

the same. We wanted to have a fully validated green roof
model (based on physics principles), and back on those days
we could not find the type/quality of experimental data to
do this job so we produced this laboratory-grade data. <o:p></o:p></span></p>

or higher. However, typical LAI values for extensive
green roofs (substrate/soil thickness less than 6”)
are around 1–3. For my PhD Thesis at PennState I
measured among other things the LAI of a healthy green
roof sample with <i>Delosperma nubigenum</i>. The LAI
was 2.7. </span><o:p></o:p></p>
