Lighting is a concern in Passive Houses and the comments posted are good points. However, in this house ninety percent of the lights that were used are either CFL's or LED's. All track lighting uses the Helios LED Head initial 5.8 watts and stabilized at 4.9 watts (also dimmable). This is substantially different than a common MR16 low voltage incandescent fixture or PAR 30 please compare wattages. The house has an abundance of natural light in the daytime and at night depending on the owners preference there are multiple lighting options. Passive House does need to meet a Primary Energy requirement of ≤ 120 kWh/m2/year (38.1 kBtu/sf/yr) so all energy use is scrutinized. Currently this house is tracking a LEED for Homes Platinum rating and for lighting we are anticipating maximum points for EA8.
