I thought this group might be interested as well so here is the link... Read more

In addition to improvements to the traditional gravity system, pressure- and vacuum-assisted flushing systems are available that offer superior performance—albeit often with some increase in flushing noise.

Happy Monday all!

Does anyone know where one can locate weather files (EPW) that has predicted future data for climate change?

Thanks in advance.
