Appendix G (Table 3.1) states that lighting power for building facades has to be modeled in the energy simulation. However, it is not clear if landscape lighting should also be taken into account. Do we have to implement the external lighting of the building grounds (walkways, landscape lighting...)? Thanks

All energy use within the LEED project boundary must be included. Landscape lighting should be included within the space lit. If none of the tradable surfaces apply then it is an unregulated, process load and must be modeled identically in both models.
