[Bldg-sim] LEED Baseline system definition

[Javier Duran]

i agree with that, in this case biomass is consider renewable, but in can't
be offset from energy cost
thaks a lot for all your coments

> A basic principle of Appendix G is that fuel switching is not an energy

> on the type and source of the biomass fuel, it may be considered "renewable"
> for LEED. If it qualifies as a renewable energy source, the energy cost
> becomes zero in the proposed case, and significant savings might be realized
